Understanding Radiation via Antennas

It can be hard to grasp that radio waves, deadly radiation, and the light we can see are all the same thing. How can electromagnetic (EM) radiation – photons – sometimes penetrate walls and sometimes not? How can some forms of EM radiation be perfectly safe and others damage our DNA? How can radio waves travel so much further than gamma rays in air, but no further through concrete?

It all comes down to wavelength. But before we get into that, we should at least take a glance at what EM radiation really is.

Electromagnetic radiation takes the form of two orthogonal waves. In one direction, you have an oscillating magnetic field. In the other, an oscillating electric field. Both of these fields are orthogonal to the direction of travel.

These oscillations take a certain amount of time to complete, a time which is calculated by observing the peak value of one of the fields and then measuring how long it takes for the field to return to that value. Luckily, we only need to do this once, because the time an oscillation takes (called the period) will stay the same unless acted on by something external. You can invert the period to get the frequency – the number of times oscillations occur in a second. Frequency uses the unit Hertz, which are just inverted seconds. If something has the frequency 60Hz, it happens 60 times per seconds.

EM radiation has another nifty property: it always travels at the same speed, a speed commonly called “the speed of light” [1] (even when applied to EM radiation that isn’t light). When you know the speed of an oscillating wave and the amount of time it takes for the wave to oscillate, you can calculate the wavelength. Scientists like to do this because the wavelength gives us a lot of information about how radiation will interact with world. It is common practice to represent wavelength with the Greek letter Lambda (λ).

Put in a more mathy way: if you have an event that occurs with frequency f to something travelling at velocity v, the event will have a spatial periodicity λ (our trusty wavelength) equal to v / f. For example, if you have a sound that oscillates 34Hz (this frequency is equivalent to the lowest C♯ on a standard piano) travelling at 340m/s (the speed of sound in air), it will have a wavelength of (340 m/s)/(34 s-1) = 10m. I’m using sound here so we can use reasonably sized numbers, but the results are equally applicable to light or other forms of EM radiation.

Wavelength and frequency are inversely related to each other. The higher the frequency of something, the smaller its wavelength. The longer the wavelength, the lower the frequency. I’m used to people describing EM radiation in terms of frequency when they’re talking about energy (the quicker something is vibrating, the more energy it has) and wavelength when talking about what it will interact with (the subject of the rest of this post).

With all that background out of the way, we can actually “look” at electromagnetic radiation and understand what we’re seeing.

Wavelength is very important. You know those big TV antennas houses used to have?

Turns out that they’re about the same size as the wavelength of television signals. The antenna on a car? About the same size as the radio waves it picks up. Those big radio telescopes in the desert? Same size as the extrasolar radio waves they hope to pick up.

Even things we don’t normally think of as antennas can act like them. The rod and cone cells in your eyes act as antennas for the light of this very blog post [2]. Chains of protein or water molecules act as antennas for microwave radiation, often with delicious results. The bases in your DNA act as antennas for UV light, often with disastrous results.

These are just a few examples, not an exhaustive list. For something to be able to interact with EM radiation, you just need an appropriately sized system of electrons (or electrical system; the two terms imply each other). You get this system of electrons more or less for free with metal. In a metal, all of the electrons are delocalized, making the whole length of a metal object one big electrical system. This is why the antennas in our phones or on our houses are made of metal. It isn’t just metal that can have this property though. Organic substances can have appropriately sized systems of delocalized electrons via double bonding [3].

EM radiation can’t really interact with things that aren’t the same size as its wavelength. Interaction with EM radiation takes the form of the electric or magnetic field of a photon altering the electric or magnetic field of the substance being interacted with. This happens much more readily when the fields are approximately similar sizes. When fields are the same size, you get an opportunity for resonance, which dramatically decreases the loss in the interaction. Losses for dissimilar sized electric fields are so high that you can assume (as a first approximation) that they don’t really interact.

In practical terms, this means that a long metal rod might heat up if exposed to a lot of radio waves (wavelengths for radio waves vary from 1mm to 100km; many are a few metres long due to the ease of making antennas in that size) because it has a single electrical system that is the right size to absorb energy from the radio waves. A similarly sized person will not heat up, because there is no single part of them that is a unified electrical system the same size as the radio waves.

Microwaves (wavelengths appropriately micron-sized) might heat up your food, but they won’t damage your DNA (nanometres in width). They’re much larger than individual DNA molecules. Microwaves are no more capable of interacting with your DNA than a giant would be of picking up a single grain of rice. Microwaves can hurt cells or tissues, but they’re incapable of hurting your DNA and leaving the rest of the cell intact. They’re just too big. Because of this, there is no cancer risk from microwave exposure (whatever paranoid hippies might say).

Gamma rays do present a cancer risk. They have a wavelength (about 10 picometres) that is similar in size to electrons. This means that they can be absorbed by the electrons in your DNA, which kick these electrons out of their homes, leading to chemical reactions that change your DNA and can ultimately lead to cancer.

Wavelength explains how gamma rays can penetrate concrete (they’re actually so small that they miss most of the mass of concrete and only occasionally hit electrons and stop) and how radio waves penetrate concrete (they’re so large that you need a large amount of concrete before they’re able to interact with it and be stopped [4]). Gamma rays are stopped by the air because air contains electrons (albeit sparsely) that they can hit and be stopped by. Radio waves are much too large for this to be a possibility.

When you’re worried about a certain type of EM radiation causing cancer, all you have to do is look at its wavelength. Any wavelength smaller than that of ultraviolet light (about 400nm) is small enough to interact with DNA in a meaningful way. Anything large is unable to really interact with DNA and is therefore safe.

Epistemic Status: Model. Looking at everything as antenna will help you understand why EM radiation interacts with the physical world the way it does, but there is a lot of hidden complexity here. For example, eyes are far from directly analogous to antennas in their mechanism of action, even if they are sized appropriately to be antennas for light. It’s also true that at the extreme ends of photon energy, interactions are based more on energy than on size. I’ve omitted this in order to write something that isn’t entirely caveats, but be aware that it occurs.

Footnotes:

[1] You may have heard that the speed of light changes in different substances. Tables will tell you that the speed of light in water is only about ¾ of the speed of light in air or vacuum and that the speed of light in glass is even slower still. This isn’t technically true. The speed of light is (as far as we know) cosmically invariant – light travels the same speed everywhere in the galaxy. That said, the amount of time light takes to travel between two points can vary based on how many collisions and redirections it is likely to get into between two points. It’s the difference between how long it takes for a pinball to make its way across a pinball table when it hits nothing and how long it takes when it hits every single bumper and obstacle. ^

[2] This is a first approximation of what is going on. Eyes can be modelled as antennas for the right wavelength of EM radiation, but this ignores a whole lot of chemistry and biophysics. ^

[3] The smaller the wavelength, the easier it is to find an appropriately sized system of electrons. When your wavelength is the size of a double bond (0.133nm), you’ll be able to interact with anything that has a double bond. Even smaller wavelengths have even more options for interactions – a wavelength that is well sized for an electron will interact with anything that has an electron (approximately everything). ^

[4] This interaction is actually governed by quantum mechanical tunneling. Whenever a form of EM radiation “tries” to cross a barrier larger than its wavelength, it will be attenuated by the barrier. The equation that describes the probability distribution of a particle (the photons that make up EM radiation are both waves and particles, so we can use particle equations for them) is approximately  (I say approximately because I’ve simplified all the constants into a single term, k), which becomes  (here I’m using k1 to imply that the constant will be different), the equation for exponential decay, when the energy (to a first approximation, length) of the substance is higher than the energy (read size of wavelength) of the light.

This equation shows that there can be some probability – occasionally even a high probability – of the particle existing on the other side of a barrier.  All you need for a particle to traverse a barrier is an appropriately small barrier. ^

An Update on a Prediction

Back in February, I predicted that the slew of scandals Trudeau was facing wouldn’t decrease his approval ratings. To put numbers on this, I gave my confidence intervals for Trudeau’s approval ratings in April.

Thanks to the “Leader Meter“, it’s easy for me to check up on how Trudeau is doing. As of right now, the most recent poll has him at 48% approval (this is conveniently the first poll since April 1st, making it useful for the purposes of checking my prediction), while Éric Grenier’s model has him at 50.6% approval.

Both of these are within all three probability intervals I offered. In addition, Trudeau was polling higher in March than he was in February, further evidence that the scandals in February (and the abandonment of electoral reform) haven’t hurt his popularity.

I continue to believe that the erosion of political norms around scandals during Steven Harper’s time in office has played a large role in Trudeau’s enduring popularity.

On Low-Income Voters and Self-Interest

Neil McDonald’s new column points out that Trump’s low-income supporters voted against their own economic self-interest. This presents a fine opportunity for Mr. McDonald to lecture those voters about how bad Trump’s policies will be for them, as if they couldn’t have figured it out themselves.

I say: some of Trump’s supporters voted against their own self-interest? So what? Hillary Clinton’s well-off supporters, from Sam Altman, to many of my friends in the Bay Area did as well.

Back in Canada, I have even more examples of people who voted against their self-interest. They include myself, Mr. McDonald (in all likelihood), a bevy of well off technologists and programmers, and a bunch of highly educated students who expect to start high-paying jobs before the next election.

Just like Trump’s lower-income voters, we knew what we were getting into. We understood that we were voting for higher taxes for people like us. We voted for higher taxes because we like the things taxes buy – infrastructure, social services, and science funding, to name a few.

I have no doubt Mr. McDonald would understand this. But when it comes to low-income voters putting their aspirations for their country above their self-interest, he’s flabbergasted.

Americans are raised to believe that anything is possible in America if you are pure of heart and willing to work hard, which is nonsense, and that anyone can become president, which is even more foolish, and that free markets always make the right decision, which is nuts.

They are told that rugged individualism is the American way, which it isn’t, and that government is never the solution, which it sometimes most definitely is.

Mr. McDonald forgot to wonder if the people voting for Trump might desperately want these things to be true. What if the people he’s talking about really wanted everything he listed to be true and saw voting for Trump as their best chance to make them reality? What if they understood what they might lose and chose to vote anyway? Why should he believe they’re less likely to evaluate the consequence of a vote than he is? If any of these are true, are these voters still sheep led astray by right-wing politicians? Or are the politicians just responding to a real demand from their constituents?

These are the sorts of questions I’d like to see journalists who want to write about people – especially low-income people – voting against their economic self-interest grapple with.

It’s certainly unlikely that Mr. Trump will be able to deliver everything his supporters hope he will or everything he’s promised. That makes him a liar, or more charitably, overambitious. It doesn’t make his followers worthy of scorn for the simple act of voting for the type of society they wanted.

I would like to note that I view many of Trump’s policies as wrong-headed and profoundly lacking in compassion. I have no objections to someone scorning Trump voters because those voters seem to prefer fear to compassion and division to equity. I simply object to the hypocrisy of journalists mocking low-income Republicans for the same actions for which they lionize well-off Democrats (replace with Conservatives and Liberals if you’re in Canada and it still holds).

Why should people vote for their economic self-interest anyway? Sure, studies show that money totally can buy happiness, but it’s not the only thing that can. You can also become happy by living in a place that embodies your values. What left-wing think pieces criticizing the poor for voting against their interests miss is that this is true no matter how much money you make.

Here’s one theory of political consensus: if everyone votes for the policies that will be most to their own economic benefit, we’ll end up with compromise policies that tend to economically benefit everyone reasonably well. Here’s a different take: if everyone votes for the type of country they want to live in, we’ll end up with a country that fits everyone’s preferences reasonably well.

If you look at the exit poll data, it looks like people are pursuing a mix of these two strategies. Hillary Clinton won among people making less than $50,000 per year and Donald Trump won among people making more. While this may look like people are mainly voting in their economic interest, all of these margins were remarkably thin and notably much smaller than they were in the last election cycle. This could be indicative of more and more people voting aspirationally, rather than economically.

One interesting tidbit for Mr. McDonald though – if you look at the exit poll data, it turns out low income voters are the ones least likely to vote against their own self-interest.

International Trade Explained with Jellybeans

Imagine that you’re a young teenager who really loves red jellybeans. You love them so much that you unabashedly call them your favourite food. It’s only the red ones though – you find all other jellybeans disgusting. For the purposes of this extended metaphor, you will have a sister. Like you, she loves one colour of jellybeans, but unlike you she only loves the green ones.

Image Credit: Larry Jacobsen on Flickr

Your parents are stingy. They long ago realized that they could save a lot of money by paying you for your chores in jellybeans, instead of with an allowance. To prop up this system, they’ve forbidden both you and your sister from buying jellybeans in any store. Both of you can only get jellybeans from your parents. You each get a few jellybeans of your preferred colour each time you complete a chore.

You keep a small horde of jellybeans in a jar in your room. Chores are irregular and you don’t want to risk having a jellybean craving but no way to get jellybeans. It’s pretty inconvenient that you and your sister like different flavours of jellybeans. If this wasn’t the case, you could use jellybeans as a sort of currency, trading them back and forth for various small things. For example, if only you liked the same jellybeans, she could give you jellybeans in exchange for using your new Nintendo Switch for a bit, while you could give her jellybeans to help you sneak out at night. You do this sometimes already, but only when you both want something of the other at the same time.

One day your sister takes the bus to a friend’s house. On the way, she happens to sit next to an economics professor. She complains to the professor about her plight and the professor offers a solution. Your sister comes home that night with a large grin splitting her face.

The scheme she proposes to you is simple. When you don’t have two things to trade at the same time, you’ll use jellybeans as your currency. If you agree to accept her jellybeans as payment, she’ll accept yours. You’ll both have the understanding that someday your sibling will trade those jellybeans back to you for some other thing. As the first trade, she offers you fifteen of her green jellybeans for one hour on your Nintendo Switch.

You think about it for a few minutes. It’s true that the fifteen green jellybeans are worthless to you. But they aren’t worthless to your sister and she will probably eventually want them back. As long as you trust that she’ll be around in the future and will still want green jellybeans, you may as well accept the trade. You’ve now realized that green jellybeans are useful to you even though you can’t eat them to feed your jellybean cravings.

You and your sister successfully trade like this for a few weeks. There are some wild fluctuations in your horde of jellybeans – some days it’s mostly red, other days it’s almost entirely green – but over the long run it tends towards red and you get to enjoy all of the benefits of trading with your sister. You’ve successfully snuck out to see your friends three times, while she’s made it halfway through the new Zelda game. It’s at this point where she comes to you with a discovery.

She’s invented a chemical that she can mix with a jellybean to double its size. She can’t make very much of it, only enough to make thirty new jellybeans a day. She makes a deal with you: she’ll use the chemical on your jellybeans in the proportion that they appear in her stash, but she’ll still own them afterwards and they’ll be worth twice as much in future trades.

Slowly the trading relationship changes. Your sister does fewer favours for you – although she doesn’t stop completely. Meanwhile, an increasing amount of your wealth of jellybeans end up with her, despite her playing your Switch very often. You don’t mind this arrangement, because you end up with many more jellybeans than you would have without her. Your sister doesn’t mind either, because it’s made playing the Switch much more accessible to her. That said, there are some negatives for her as well. She’s gotten noticeably weaker without the exercise from chores.

Eventually your parents catch on to this and confiscate your sister’s chemistry set. Furthermore, they punish her by cutting her jellybean allotment in half. Now, she’ll make half of what you do for the same chores. Worried about the effect of video games on her, they also limit the total screen time either of you is allowed (they ignore you whining that this is totally unfair) and demand that you each do one chore per day.

You still trade after this, although now things swing in the other direction. Your sister has to scrimp and save to afford time on the Switch, whereas you have an easier time hiring her as a lookout.

A few weeks later, your parents go on vacation. While they’re gone, they want you both to record the chores you do. When they get back, they’ll question you separately about the honesty of the chore log. If you both agree that it’s true (and they can see the chores actually got done), they’ll give you jellybeans for all the chores recorded on it.

They also switch up the compensation a bit. You’ve been spending more time inside these days, now that you’re lending the Switch to your sister less often, while your sister has gotten strong from all the yard-work she’s been doing. Your parents don’t really approve of this, so they’re changing the rewards that chores give.

Under the new rules, your sister still makes generally less than you, but it isn’t evenly distributed; she makes almost as much as you for chores inside of the house and much less than you for chores outside it. This is crappy for you, because now you’re the weak one. Your sister can do chores outside in half the time it would take you.

You and your sister immediately hatch a plan to do each other’s chores and later divide the spoils evenly. Your parents are too clever for this though. They tell you they’ll be watching your jellybean transactions for the next little bit. If you two split the difference and lie, they’ll know and they’ll ground both of you for a week. You’re both dejected, doomed to doing chores you aren’t good at. In a last-ditch effort to find something more palatable, your sister emails her economist friend from earlier.

She comes back a few hours later, contemplative. The economist offered a solution, but it seems odd.

The economist recommended that you lie about the chores; your sister will do all of the ones outside and you’ll do all of the ones inside. To get around your parent’s crude attempt at lie detection, you’ll do something simple. You won’t split the difference; you’ll accept payment in full for the chores you claimed to do and get to spend it as if it were yours.

Even though this seems unfair, it leaves both you and your sister better off overall. By focusing on the chores you’re both quickest at, you can maximize the number of jellybeans you earn for each unit of time you spend working. You both agree to this plan.

When they get back, your parents are suspicious of your sister’s muscles and the deep impression you’ve worn in the couch. They monitor your transactions for quite some time. But they never find any evidence that you averaged your take with your sister and eventually they give up and leave you alone.

In the fall, your sister plans to leave for the annual mother-daughter fishing trip your extended family does. The trip lasts two whole weeks. In the weeks leading up to the trip, you begin to panic. While your sister is gone, you won’t be able to get any of your jellybeans from her. Combine this with your worry that you will have fewer chances to earn jellybeans for chores with only one parent home and you start to have a problem. What if you run out of jellybeans because a bunch of the red ones are hoarded by your sister?

To counter this, you stop accepting your sister’s green jellybeans in trade for favours and only trade green jellybeans back to her when you need something done. Eventually you run out of green jellybeans. Now you can’t get her to do anything. You won’t risk your red jellybeans so close to her trip.

Unfortunately, you don’t get all of your jellybeans back this way. Your sister begins to hoard them, knowing that they’re the only thing she can use to really get you to do anything for her. Despite you trying to get all your jellybeans back, you’ve made her hold onto them even tighter.

She’s pretty annoyed with all of this, because she wants to trade with you like before. In desperation, she emails her economist friend. Once again, the economist comes through for you. Your sister offers you a deal. She currently has 100 red jellybeans. At the end of every day, you can convert up to twenty green jellybeans for red ones at a rate of one to one. Normally you wouldn’t bother with this (and sometimes one of you lacks the means to), but she’ll give you this option for the next week so that you can accept her jellybeans with confidence.

This works quite well. Your mutually beneficial trades resume. When your sister leaves for her fishing expedition, she only has ten of your jellybeans left. You’re not going to run out in her absence.


Everything that was observed between the two siblings trading with jellybeans can be observed (in one form or another) between countries trading.

For this metaphor to work, the medium of exchange (jellybeans of different colours) had to be something that was so similar as to be essentially the same thing while being treated as vastly different by the participants. This is how people in different countries treat each other’s money.

As a Canadian, I need Canadian Dollars to pay my expenses. If I walk into a grocery store or get on a bus and try to pay with Swiss Francs or Japanese Yen, I will be refused service. Because I want to eat and take the bus, if I were sell goods or services outside of Canada, I would only accept as payment:

  1. Canadian Dollars
  2. Something else I know is trivially convertible to Canadian Dollars at a stable rate

People in other countries are in the same boat as me. Even if there’s something they want to sell me, they can’t unless I can provide them something that holds stable value for them. Canadian Dollars are only valuable to them insofar as they can use them to buy things they want in Canada or, if they don’t want anything in Canada, trade them for something they want with someone who wants something in Canada.

You can’t get something for nothing. For someone to send me goods (that aren’t simply a gift) from outside of Canada, they must want something in Canada or know about someone who does. This is the principle that allowed you to trade with your sibling. Her jellybeans weren’t inherently useful to you, but they were stably convertible into things that were, which made it reasonable for you to accept them as payment.

The ease of currency conversion often hides this from us. To see it, you need to look at exchange rates. Exchange rates are nothing more than a measure of the relative demand for goods and services produced by countries and debts denominated in their currencies.

When America was in financial crisis and Canada was raking in huge oil profits, people wanted Canadian Dollars just as much as they wanted American Dollars. Now that America has recovered, people would prefer to have American Dollars (USD) and so the Canadian Dollar is only worth about $0.75 US. Had either you or your sister been able to offer much more valuable services, you might have seen an exchange rate other than 1:1, with it favouring whoever offered the better stuff.

If I’m right about this, we’d expect to see countries import as much as they export. Trade deficits shouldn’t exist. As Donald Trump might be happy to remind you, trade deficits do indeed exist. What’s going on? How is this possible?

Trade deficits can occur when trade is financed via debt. A country might borrow money denominated in another currency (which has a more stable value than its own) and use that borrowed money to purchase things. This is essentially a country promising that it will have exports of value to the lender at some point in the future. This is how developing nations can have trade deficits, but it isn’t generally how developed nations pull them off.

We can view America (and other developed nations with a trade deficit) as similar to your sister when she had the tools to create more jellybeans out of otherwise worthless chemicals. She was definitely doing less things of direct value for you than you were for her (e.g. she was standing lookout for you much less often than she was borrowing video games from you), but she was able to do this sustainably because she had a way of making the jellybeans to pay for it.

Developed nations can have a trade deficit in a sustainable way because other countries will give them raw materials or physical goods simply for the privilege of holding debt denominated in their currency or being able to buy property within their borders. The sophisticated financial systems of developed countries allow them to reliably and safely (most of the time) create money for anyone willing to invest. How do you get money to invest if you don’t live there? You trade for it!

Developed countries are still providing goods and services to their trade partners, even if they aren’t tangible or recorded on balance sheets as exports. Sometimes this does mean that trade is funded by loans, but crucially, the debt is generally denominated in the currency of the debtor country. This makes repayment much, much easier.

Countries have many more options for repaying debts denominated in their own currencies. Japan can safely have a government debt of several times its GDP because the debt is denominated in Yen. Japan controls the means to print more Yen, so is able to pay its debt just by printing more money. There are obviously problems with just printing money (i.e. inflation), but these apply less to Japan because of its overall economic situation (i.e. deflation). On the other hand, Greece’s debt burden was so bad specifically because it can’t print the Euros its debt is denominated in itself. It needs to produce things other countries want in order to raise the cash it needs to pay down its debt.

There are certainly ways that funding trade via financial products can go sour. If the financial system that provides for the trade deficit relies on high consumer debt, then a financial shock could make it all come crashing down and deprive a country of the exports they’re used to receiving. But when trade deficits are based on the security and sophistication of a nation’s financial institutions (or the value of its real estate, or something else that is relatively stable), that nation stands to benefit enormously. It can receive tangible goods just by letting other countries invest or loan with its currency.

Seen this way, Canada’s trade deficit with China (as an example) is caused because many Chinese people have been willing to ship us manufactured goods in exchange for the ability to invest in our companies, buy real estate in Toronto and Vancouver, and make loans to us.

There are trade-offs here. On one hand, foreign investment in housing has probably made living in Toronto and Vancouver less affordable. On the other hand, it has made electronics and manufactured goods available at lower prices than they would otherwise be. Whether this is good or bad for you personally depends on where you live and how often you buy manufactured goods.

There are also trade-offs around employment here. It’s not a simple matter of trade with developing nations costing us manufacturing jobs. It probably has! But I’d like to point out if trade has cost us jobs in manufacturing, it has certainly created jobs in construction and in finance. Houses aren’t built without workers and investments can’t be made without investment assistants and portfolio managers. These may not be manufacturing jobs, but they’re still jobs.

This shades into the next example from the jellybean world. When you and your sister could both work jobs at very different rates of compensation, you weren’t made worse off by letting you sister do half of the chores. You weren’t really in competition with you sister. Despite much of the rhetoric about trade being a competition, trade with another country isn’t a competition with that country.

When split up between two countries that are trading, jobs don’t get done based on who had the competitive advantage. Since trade cannot happen unless both parties benefit (remember, if no one outside Canada wants anything Canada produces, I will be unable to buy anything outside of Canada with Canadian dollars) the fact that trade is happening at all means that each country has something the other wants. Given this, what gets traded will be determined by the relative advantages industries in each country have over the industries within that country. This is the comparative advantage theory of trade.

China has the advantage of relatively cheap labour but has the disadvantage of relatively high corruption. When you compare China with Canada, China’s manufacturing sector is advantaged over their financial sector, so they will tend send Canada manufactured goods in exchange for Canadian financial instruments.

Even when your sister was making less than you for every chore, you and her were still able to trade for mutual benefit. You got to do only the chores you found easiest while still gaining enough jellybeans to trade for things you wanted from your sister. People (and countries) don’t act blindly to maximize the amount of money they make. They have other desires as well. You would have only been in competition with your sister if you wanted to blindly maximize your total haul, without a thought for how much leisure it would cost you.

Competition would also come up if your parents were looking to minimize the amount they paid for chores. In this case, your sister would have had a competitive advantage. But this isn’t a competition within your trading relationship with you sister! Here you would be competing for the business of some third party (your parents).

You are never competing with your trade partners within the context of the trading relationship. It would be impossible for the whole American economy to move to China (no matter how often Donald Trump claims it is happening) because if this happened China would refuse to sell America anything and America would again require indigenous industries. If industries get outsourced and aren’t replaced by something else that adds value, you’ll see them pop right back up in their original country. Outsourcing is only cheaper when you have things of value to buy the outsourced products with.

You can be competing with your trade partners for third party business, but the answer here isn’t to raise tariffs and abandon trade. Instead, you can reap the benefits of an integrated supply chain and the overall lower costs you see when countries focus on their comparative advantages. For example, Apple has become one of the largest companies in the world by marrying American business expertise, stability, and engineering know-how with Chinese and Taiwanese manufacturing, which allows them to compete with Samsung, a Korean company (which also makes use of Taiwanese/Chinese manufacturing).

Apple products would be more expensive if manufactured solely in the United States. They wouldn’t be a global luxury brand if they were designed and marketed from China. Apple wouldn’t be a global behemoth without trade. When the CEOs of companies stand up for international trade, they’re doing so because they understand this.

It is possible for a country to be in a state such that basically no one wants to trade with them, often because they produce very little of value to anyone else. Take North Korea as an example here. They’re able to trade some coal to China (in exchange for manufactured goods) and managed to make a one-off trade with Pakistan (swapping missiles for atomic bomb designs and materials), but by and large the rest of the world doesn’t want to trade with them. Since the government is pursuing a policy of juche (“self-reliance”), North Korea isn’t much bothered by this.

Unfortunately, lack of trade doesn’t always happen by choice. Venezuela spent more than a decade squandering oil wealth on everything but productive infrastructure. When oil prices were high this was fine. Venezuelans could trade oil to other countries and in return they received all of the food, medicine, and manufactured goods they could want. This worked while global oil demand outstripped supply. Now that demand for oil has considerably lessened, Venezuela is facing serious difficulties importing necessities.

Because there’s little of value in Venezuela, no one wants to hold on to the Venezuelan currency (the Bolivar). Currently about all its good for is buying sub-par oil. This would suggest that Venezuela should be unable to important much of anything and indeed that’s what we’re observing.

In the jellybean world, we saw something similar. When your sister was about to leave on her trip, you didn’t want to trade with her, because her currency would soon be worthless. She was able to convince you to trade by using her reserves of your jellybeans.

Venezuela is currently able import goods via a similar mechanism. During the oil boom, the government of Venezuela was able to amass a significant number of American Dollars. It is now using this stockpile to pay for imports. Venezuela actually has three official exchange rates. If you are importing key goods, the government will turn your Bolivars into USD at a very preferential rate, 10 Bolivars for 1 USD. If you’re importing less critical goods, you’ll get fewer dollars per Bolivar. If you’re just a private citizen, the government will give you a much worse deal, something like 190 Bolivars to the dollar. It will also limit the amount you can exchange at any one time.

At the time of writing, the unofficial exchange rate was 3014 Bolivars per USD. You can make a lot of money if you bring USD into Venezuela, convert it to Bolivars on the black market, then use the government to convert it back to USD. The only loser here is the Venezuelan government (and you if you’re caught – please don’t actually do this).

Propping up the value of a currency this way is very expensive. If the Bolivar loses no more purchasing power, then Venezuela can limp along like this for two more years. If oil becomes cheaper or Venezuela becomes less able to export it, then Venezuela will lose purchasing power and that grace period shrinks. Once Venezuela exhausts its currency reserves it will be essentially unable to import anything and this story will end the same way every story about socialism ends: with a horrific famine.

This of course assumes that Venezuela doesn’t attempt to seize what it needs from its neighbours using force. Throughout this post I’ve assumed that trade has been undertaken freely for the mutual benefit of all participants. This hasn’t always been the case.

Colonialism is perhaps the best example of trade where one participant was compelled to participate. In colonies Europeans used force to extract resources and labour from non-Europeans. The colonizing Europeans would then ship these raw goods back to their home country in exchange for manufactured goods they couldn’t get from in the colony.

Trade was only ever disastrous for the colonized. They were forced to produce cash crops or mine until they were nearly dead from exhaustion, all in exchange for goods that they would never receive and had little use for even if they had.

There’s one last concept to cover. Let’s return to the jellybean metaphor!


Your sister gets deeply addicted to a game on your Nintendo Switch. Unfortunately, she’s still getting far fewer jellybeans than you are. She has to do a lot of chores just to get to play it at all, many of which aren’t particularly fun or pleasant. Because of your control of the Switch, you don’t have to do any chores; you always have some of your sister’s jellybeans to trade for whatever you need. While your sister might be happy while playing her game, she’s deeply peeved about all the chores she has to do in order to be able to play it all.

Eventually, your sister’s desire for video games overcomes the number of jellybeans she can earn. You allow her to pay you in IOUs. Soon she’s racked up hundreds of them. When she finally beats the game and has free time for other things, she realizes that she’s going to have to spend weeks working and giving you all the jellybeans just to pay off the debt she owes.

She tries to default, but you go to your parents. They decide that she can’t be trusted to pay off the debt on her own, so they’ll give you red jellybeans for every chore she completes until she’s settled the account. Now your sister is stuck doing all the chores without any benefit to herself. It takes her weeks to dig herself out of her hole and start receiving green jellybeans again.


Even when trade technically makes people better off, it can be a devil’s bargain. The benefits of modern medicine and technology (like smartphones) are so overwhelming that many developing economies must set aside a significant amount of their potential productivity creating products that aren’t locally useful so that they have something developed countries want and will trade medicine and technology for.

This can lead to vast monocultures of cash crops grown only for foreign export, stifling unsafe textile factories, and vast poisonous open pit mines.

It’s not just modern necessities that cause countries to give over vast portions of their economies to export. Poor (one might even say predatory) lending practices by world financial institutions have left many nations with unsustainable foreign debts, denominated in foreign currencies.

Remember, the only way to get foreign currencies is by having something foreign countries want and being willing to sell it to them. As long as a country has foreign debts to service, it must leave aside a chunk of its productivity for foreign rather than domestic priorities. If the pie is big and the slice set aside for other countries is small, this is sustainable. But when a small pie requires a big slice, disaster can strike. Debt relief for struggling countries remains an urgent humanitarian priority.

In real life, the IMF and the World Bank have taken a role not unlike that of your parents in the metaphor. They threaten poor debtor countries with dire consequences unless they continue to pay down their (often) ridiculously large debts. This occurs even when debts were racked up by dictators, or are for money that was stolen from the public purse by corrupt administrators.

All serious advocates of international trade need to acknowledge and grapple with the negative consequences trade can have.

But I’m hopeful. I refuse to believe that there exists no way we can make essential generic medicine and essential modern technology available to all of the people of the world except through unsafe working conditions and environmental destruction. Debt write-offs can fix some of the problems, but other reforms can only occur once the narrative around trade changes.

Framing trade as an adversarial process allows business interests to push for the rollback of worker and environmental protections where they exist and fight their introduction where they don’t. Protectionist rhetoric, whether it comes from Donald Trump or Bernie Sanders, is wrong and hurts workers the world over. Trade isn’t a competition. Framing it that way may be useful for politicians when they are competing for votes, but it won’t improve the material situation of anyone, at home or abroad.

As prosperity increases, all of these problems become more tractable. International trade remains one of the best ways we have of increasing prosperity. We can’t afford to go without it. Trade is something people should be able to agree on, whether they want to meet the UN’s Sustainable Development Goals and ensure a just global society, or just plain get rich.


My primary source was Joseph Heath’s wonderful economics book, Filthy Lucre (subtitled Economics for People who Hate Capitalism). It systematically dismantles 12 common economic fallacies, 6 beloved of the left and 6 beloved by the right. Trade is covered in Chapter 5: Uncompetitive in Everything.

The rest comes from reading too many articles on Wikipedia and too many news think pieces. Some things only became clear to me as I was writing this, like the difference between Japan’s debt and Greece’s. I’m also indebted (heh) to Tessa Alexanian, who explained to me why trade can be bad for developing countries. She influenced most of the ideas laid out in that section (that said, I should get all the credit for any errors).

As usual, this blog post should only be taken as an accurate account of my own views, not the views of anyone else.

Cutting the Gordian Knot: Bad Solutions to Good Paradoxes

Russel’s Paradox

In a village, the barber shaves everyone who does not shave himself, but no one else. Who shaves the barber.

Imagine The Barber as similar to The Pope. When he is in his shop, cutting hair, he is The Barber and has all of the powers that entails, just as The Pope only possesses the full power of papacy when speaking “from the chair”. When The Barber isn’t manifesting this mantle, he’s just Glen, the nice fellow down the lane. Glen shaves his own beard. The Barber therefore doesn’t have to.

Alternatively, the barber is a woman.

Omnipotence Paradox

Can God create a rock so large that he himself cannot lift it?

It depends.

In Christian theology, God is often considered all-knowing, all-powerful, and all-loving. Some theologians dispute each of these, but most agree he has at least some mix of those three attributes. It turns out the answer to this paradox depends on which theologians are right.

This question is only interesting if god is all-powerful. If God isn’t all powerful, then this question will be determined by which is greater: his power of creation, or his power to manipulate creation. That’s a boring answer, so let’s focus on the cases where God is all powerful.

If God is all-knowing, then we’ll probably be left unsatisfied. God will know if he can or cannot create the boulder, so he’ll probably feel no need to test if he can.

If God is not all-knowing but is all-loving, then the question will only be answered if God cannot lift the first boulder he creates. If he can lift the first one, he will quickly realize that he could end up spending all of eternity trying to make a big enough boulder on the off chance that this is the one he finally cannot lift. An all-loving God would not abandon his flock for such a meaningless task, so we’ll never see the answer.

If God is neither all-knowing nor all-loving and has at least a bit of curiosity, then we should be able to eventually observe him trying to create a boulder large enough that he cannot lift it. This God won’t know the answer and wouldn’t necessarily care that finding out requires abandoning all of his other duties.

Given that this question was first posed right before the crusades, I believe that we’re experiencing the third scenario. The mere act of raising this paradox caused God to turn his face away from the world and worry about more interesting problems than those caused by a bunch of jumped up apes.

Zeno’s Paradox

If you want to go somewhere, you first have to get halfway there. But to get to the midpoint, you have to go a quarter of the way. But to get to a quarter… When you subdivide like this, you’ll see that there are an infinite number of steps you must take to go anywhere. You cannot accomplish an infinite number of tasks in a finite time, therefore, movement is impossible.  

It’s a common mistake that space is infinitely sub-dividable. In fact, there is a limit to how finely you can cut space. You cannot cut the universe more finely than 1.61x 10-35m, a length called the Planck Length. The Planck length is to the width of a hair as the width of a hair is to the whole universe. It’s an unimaginably tiny length.

An important property of halving things: you get really small numbers very quickly. If you halve a distance of 1m a mere 116 times, you’ll have cut the distance as finely as it is possible to cut anything. At this point, you can halve the distance no more and you can proceed to your destination, one Planck length at a time.

Sorites Paradox

There is a pile of sand in front of you. If you remove a grain of sand from it, it will still be a pile. If you remove another, it will still be a pile. But if you keep removing them, eventually it won’t be. When does it stop being a pile?

I’m emailing ISO and the NIST about this one. I expect to have an answer after ten years and three hundred committee meetings.

The Ship of Theseus

Image Credit: Verity Cridland on Flickr

The Athenian Theseus bequeathed his ship to the city. As the ship aged, the Athenians kept it in perfect condition by replacing any planks and fittings that rotted away. Eventually, the entire ship had been replaced. This caused all of the philosophers in Athens to wonder: was it still Theseus’s Ship.

We could leave this one to ISO as well, but luckily as a Canadian I have another recourse.

The Comprehensive Economic and Trade Agreement between the EU (of which Greece is a member) and Canada considers a car “Made in Canada” or “Made in Europe” if at least 50% of the car came from there and at least 20% of the manufacturing occurred there.

Treating boats with a similar logic, we can see that as long as the Athenians were using local materials and labour (and weren’t outsourcing to the Persians or Phoenicians), the ship would count as “Made in Greece”. Since the paradox specifically states that the Athenians were doing all the restoring, this is probably a safe assumption.

If we take this and assume that Theseus had a solid grounding in trademark law – which would allow us to assume that he made his ship a protected brand like Harris Tweed, Kobe beef, Navaho, and Scotch – then we can see that the ship would still fall under the Theseus’s Ship™ brand. Most protected brands require a certain geographic origin, but we’ve already been over that in this case.

Even when philosophers argue that the boat is no longer Theseus’s Ship, they have to admit it is Theseus’s Ship™.

Unexpected Hanging Paradox

Image Credit: Adam Clarke on Flickr

A prisoner is sentenced to hanging by a judge. The judge stipulates that the sentence will be carried out on one of the days in the next week, that it will be carried out before noon, and that it must be a surprise to the prisoner.

The prisoner smirks, believing he will never be hung. He knows that if it is Thursday at noon and he hasn’t been hung, then the hanging would have to be on Friday. But then it wouldn’t be a surprise. So logically, he has to be hung before Friday. If this is the case though, he can’t be hung on Thursday, because if he hasn’t been hung by noon on Wednesday then a hanging on Thursday won’t be a surprise. Following through this logic, the prisoner could only be hung on the Monday. But then it will be no surprise at all!

This is indeed a problem if the judge is as good at logic as the prisoner. But if the judge remains blissfully unaware of logical induction, there is no paradox here. The judge will assume that by picking a day at random she can surprise the prisoner. The prisoner will no doubt be quite surprised when he is hung.

This becomes more likely if we set the problem in America, where some judges are elected and therefore aren’t governed by anything so limiting as qualifications.

History, Literature, Politics

Book Review: Hirohito and the Making of Modern Japan

Hirohito and the Making of Modern Japan is the second book I’ve read about World War II and culpability. I apparently just can’t resist the urge to write essays after books like this, so here we go again. Since so much of what I got out of this book was spurred by the history it presented, I’m going to try and intersperse my thoughts with a condensed summary of it.

Aside from the prologue, which takes place just after Hirohito’s (arguably) extra-constitutional surrender, the book follows Hirohito’s life chronologically. Hirohito’s childhood was hardly idyllic. He spent most of it being educated. Meiji Era Japan drew heavily from Prussia and in Hirohito’s education, I saw an attempt to mold him into a Japanese Frederick the Great.

I think Dr. Bix is right to spend as much time on Hirohito’s childhood as he does. Lois McMaster Bujold once criticized authors who write characters that pop out of a box at 22, fully formed. It’s even more lamentable when historians do this.

The baby Hirohito

Had Dr. Bix skipped this part, we’d have no explanation for why Hirohito failed so completely at demonstrating any moral fibre throughout the war. In order to understand Hirohito’s moral failings, we had to see the failings in Hirohito’s moral education. Dr. Bix does an excellent job here, showing how fatuous and sophistic the moral truths Hirohito was raised with were. His instructors lectured him on the moral and temporal superiority of the Imperial House over the people of Japan and the superiority of the people of Japan over the people of the world. Japan, Hirohito was taught, had to steward the rest of Asia towards prosperity – violently if need be.

For all that Hirohito might have been a pacifist personally, his education left him little room to be a pacifist as a monarch.

This certainly isn’t without precedent. The aforementioned Frederick the Great was known to complain about his “dog’s life” as a general. Frederick would have much preferred a life of music and poetry to one of war, but he felt that it was his duty to his country and his people to lead (and win wars).

Hirohito would have felt even more pressure than Frederick the Great, because he probably sincerely believed that it was up to him to save Asia. The explicitly racist immigration policies of western nations, their rampant colonialism, and their refusal to make racial non-discrimination a key plank of the League of Nations made it easy for Hirohito’s teachers to convince him that he (and through him, all of Japan) was responsible for protecting “the yellow race”.

It is unfortunate that Hirohito was raised to be an activist emperor, because as Dr. Bix points out, the world was pretty done with monarchs by the time Hirohito was born. Revolutions and First World War had led to the toppling of many of the major monarchies (like Russia, Austria-Hungary, and Germany). Those countries that still had monarchies heavily circumscribed the power of their monarchs. There were few countries left where monarchs both ruled and reigned. Yet this is what Hirohito’s teachers prepared him to do.

After an extensive education, Hirohito entered politics as the prince-regent for his ailing father, the Taisho Emperor. As regent, he attended military parades, performed some of the emperor’s religious duties, appointed prime ministers, and began to learn how Japanese politics worked.

There was a brief flourishing of (almost) true democracy based on party politics during the reign of the Taisho Emperor. Prime Ministers were picked by the emperor on the advice of the genrō, an extraconstitutional group of senior statesmen who directed politics after the Meiji Restoration (in 1868). The incapacity of Hirohito’s father meant that the genrō were free to choose whomever they wanted. Practically, this meant that cabinets were formed by the leader of the largest party in the Diet (the Japanese parliament). Unfortunately, this delicate democracy couldn’t survive the twin threats of an activist monarch and independent military.

The prime minister wasn’t the only power centre in the cabinet. The army and navy ministers had to be active duty officers, which gave the military an effective veto over cabinets ­– cabinets required these ministers to function, but the ministers couldn’t join the cabinet without orders from their service branch.

With an incompetent and sick emperor, the military had to negotiate with the civilian politicians – it could bring down a government, but couldn’t count on the genrō to appoint anyone better, limiting its bargaining power. When Hirohito ascended to the regency, the army began to go to him. By convincing Hirohito or his retinue to back this candidate for prime minister or that one, the military gained the ability to remove cabinets and replace them with those more to their liking.

This was possible because under Hirohito, consulting the genrō became a mere formality. In a parody of what was supposed to happen, Hirohito and his advisers would pick their candidate for prime minister and send him to Saionji, the only remaining genrō. Saionji always approved their candidates, even when he had reservations. This was good for the court group, because it allowed them to maintain the fiction that Hirohito only acted on advice and never made decisions of his own.

As regent, Hirohito made few decisions of his own, but the court group (comprised of Hirohito and his advisors) began laying the groundwork to hold real power when he ascended to the throne. For Hirohito, his education left him little other choice. He had been born and raised to be an active emperor, not a mere figurehead. For his entourage, increasing Hirohito’s influence increased their own.

I’m not sure which was more powerful: Hirohito or his advisors? Both had reasons for trusting the military. Hirohito’s education led him to view the military as a stabilizing and protective force, while his advisors tended to be nationalists who saw a large and powerful military as a pre-requisite for expansion. Regardless of who exactly controlled it, the court group frequently sided with the military, which made the military into a formidable political force.

Requiring active duty military officers in the cabinet probably seemed like a good idea when the Meiji Constitution was promulgated, but in retrospect, it was terrible. I’m in favour of Frank Herbert’s definition of control: “The people who can destroy a thing, they control it.” In this sense, the military could often control the government. The instability this wrought on Japan’s cabinet system serves as a reminder of the power of vetoes in government.

In 1926, the Taisho emperor died. Hirohito ascended to throne. His era name was Shōwa – enlightened peace.

Hirohito after his enthronement ceremony

As might be expected, the court group didn’t wait long after Hirohito’s ascension to the throne to begin actively meddling with the government. Shortly after becoming emperor, Hirohito leaned on the prime minister to commute the death sentence of a married couple who allegedly planned to assassinate him. For all that this was a benevolent action, it wreaked political havoc, with the prime minister attacked in the Diet for falling to show proper concern for the safety of the emperor.

Because the prime minister was honour bound to protect the image of Hirohito as a constitutional, non-interventionist monarch, he was left defenseless before his political foes. He could not claim to be acting according to Hirohito’s will while Hirohito was embracing the fiction that he had no will except that of his prime minister and cabinet. This closed off the one effective avenue of defense he might have had. The Diet’s extreme response to clemency was but a portent of what was to come.

Over the first decade of Hirohito’s reign, Japanese politics became increasingly reactionary and dominated by the army. At the same time, Hirohito’s court group leveraged the instability and high turnover elsewhere in the government to become increasingly powerful. For ordinary Japanese, being a liberal or a communist became increasingly unpleasant. “Peace Preservation Laws” criminalized republicanism, anarchism, communism, or any other attempt to change the national fabric or structure, the kokutai – a word that quickly became heavily loaded.

In the early 1930s, political criticism increasingly revolved around the kokutai, as the Diet members realized they could score points with Hirohito and his entourage by claiming to defend it better than their opponents could. The early 1930s also saw the Manchurian Incident, a false flag attack perpetrated by Japanese soldiers to give a casus belli for invading Manchuria.

Despite opposition from both Hirohito and the Prime Minister, factions in the army managed to leverage the incident into a full-scale invasion, causing a war in all but name with China. Once the plotters demonstrated that they could expand Hirohito’s empire, he withdrew his opposition. Punishments, when there were any, were light and conspirators were much more likely to receive medals that any real reprimand. Dr. Bix believes this sent a clear message – the emperor would tolerate insubordination, as long as it produced results.

After the Manchurian Incident (which was never acknowledged as a war by Japan) and the occupation of Manchuria, Japan set up a client kingdom and ruled Manchuria through a puppet government. For several years, the situation on the border with China was stable, in spite of occasional border clashes.

This stability wasn’t to last. In 1937, there was another incident, the Marco Polo Bridge Incident.

When an unplanned exchange of fire between Chinese and Japanese troops broke out in Beijing (then Peking), some in the Japanese high command decided the time was ripe for an invasion of China proper. Dr. Bix says that Hirohito was reluctant to sanction this invasion (over fears of the Soviet Union), but eventually gave his blessing.

Japan was constantly at war for the next eight years. Over the course of the war, Dr. Bix identified several periods where Hirohito actively pushed his generals and admirals towards certain outcomes, and many more where Hirohito disagreed with them, but ultimately did nothing.

I often felt like Dr. Bix was trying to have things both ways. He wanted me to believe that Hirohito was morally deficient and unable to put his foot down when he could have stood up for his principles and he wanted me to believe that Hirohito was an activist emperor, able to get what he wanted. This of course ignores a simpler explanation. What if Hirohito was mostly powerless, a mere figurehead?

Here’s an example of Dr. Bix accusing Hirohito of doing nothing (without adequate proof that he could have done anything):

When Yonai failed to act on the long-pending issue of a German alliance, the army brought down his cabinet and Hirohito did nothing to prevent it. (Page 357)

On the other hand, we have (in Hirohito’s own words) an admission that Hirohito had some say in military policy:

Contrary to the views of the Army and Navy General Staffs, I agreed to the showdown battle of Leyte, thinking that if we attacked at Leyte and America flinched, then we would probably be able to find room to negotiate. (Page 481)

I really wish that Dr. Bix had grappled with this conflict more and given me much more proof that Hirohito actually had the all the power that Dr. Bix believes he did. It certainly seems that by Hirohito’s own admission, he was not merely a figurehead. Unfortunately for the thesis of the book, it’s a far leap from “not merely a figurehead” to “regularly guided the whole course of the war” and Dr. Bix never quite furnishes evidence for the latter view.

I was convinced that Hirohito (along with several other factions) acted to delay the wartime surrender of Japan. His reasoning for this was the same as his reasoning for the Battle of Leyte. He believed that if Japan could win one big victory, they could negotiate an end to the war and avoid occupation – and the risk to the emperor system that occupation would entail. When this became impossible, Hirohito pinned all his hopes on the Soviet Union, erroneously believing that they would intercede on Japan’s behalf and help Japan negotiate peace. For all that the atomic bombings loomed large in the public statement of surrender, it is likely that behind the scenes, the Soviet invasion played a large role.

Leaving aside for a minute the question of which interpretation is true, if Hirohito or a clique including him wielded much of the power of the state, he (or they) also suffered from one of the common downfalls of rule by one man. By Dr. Bix’s account, they were frequently controlled by controlling the information they received. We see this in response to the Hull note, an pre-war American diplomatic communique that outlined what Japan would have to do before America would resume oil exports.

At the Imperial Conference on December 1, 1941, Foreign Minister Tōgō misled the assembled senior statesmen, generals and admirals. He told them that America demanded Japan give up Manchuria, which was a red line for the assembled leaders. Based on this information, the group (including Hirohito) assented to war. Here’s a quote from the journal of Privy Council President Yoshimichi Hara:

If we were to give in [to the United States], then we would not only give up the fruits of the Sino-Japanese War and the Russo-Japanese War, but also abandon the results of the Manchurian Incident. There is no way we could endure this… [I]t is clear that the existence of our empire is threatened, that the great achievement of the emperor Meiji would all come to naught, and that there is nothing else we can do. (Page 432)

The problem with all this is that Hull cared nothing for Manchuria, probably didn’t even consider it part of China, and would likely have been quite happy to let Japan keep it. By this point, the Japanese conquest of Manchuria had been a done deal for a decade and the world had basically given up on it being returned to China. Hull did want Japan to withdrawn from French Indochina (present day Vietnam) and China. Both of these demands were unacceptable to many of the more hawkish Japanese leaders, but not necessarily to the “moderates”.

Foreign Minister Tōgō’s lie about Manchuria was required to convince the “moderates” to give their blessing to war.

Hirohito presides over a similar meeting in 1943

A word on Japanese “moderates”. Dr. Bix is repeatedly scornful of the term and I can’t help feeling sympathetic to his point of view. He believes that many of the moderates were only moderate by the standards of the far-right extremists and terrorists who surrounded them. It was quite possible to have an international reputation as a moderate in one of the pre-war cabinets and believe that Japan had a right to occupy Chinese territory seized without even a declaration of war.

I don’t think western scholarship has necessarily caught up here. On Wikipedia, Privy Council President Hara is described as “always reluctant to use military force… he protested against the outbreak of the Pacific war at [the Imperial Conference of December 1]”. I would like to gather a random sample of people and see if they believe that the journal entry above represents protesting against war. If they do, I will print off this blog post and eat it.

Manipulation of information played a role in Japan’s wartime surrender as well. Dr. Bix recounts how Vice Foreign Minister Matsumoto Shinichi presented Hirohito with a translation of the American demands that replaced one key phrase. The English text of the demands read: “the authority of the Emperor… to rule the state shall be subject to the Supreme Commander of the Allied Powers”. In the translation, Shinichi replaced “shall be subject to” with “shall be circumscribed by”.

Hirohito, who (in Dr. Bix’s estimation) acted always to preserve his place as emperor accepted this (modified) demand.

Many accounts of World War II assume the civilian members of the Japanese cabinet were largely powerless. Here we see the cabinet shaping two momentous decisions (war and peace). They were able to do this because they controlled the flow of information to the military and the emperor. Hirohito and the military didn’t have their own diplomats and couldn’t look over diplomatic cables. For information from the rest of the world, they were entirely at the mercy of the foreign services.

One man rule can give the impression of a unified elite. Look behind the curtain though and you’ll always find factions. Deprived of legitimate means of conflict (e.g. contesting elections), factions will find ways to try and check each other’s influence. Here, as is often the case, that checking came via controlling the flow of information. This sort of conflict-via-information has real implications in current politics, especially if Donald Trump tries to consolidate more power in himself.

But how was it that such a small change in the demand could be so important? Dr. Bix theorized that Hirohito’s primary goal was always preserving the power of the monarchy. He chose foreign war because he felt it was the only thing capable of preventing domestic dissent. The far-right terrorism of the 1930s was therefore successful; it compelled the government to fight foreign wars to assuage it.

In this regard, the atomic bombs were actually a godsend to the Japanese leadership. They made it clear that Japan was powerless to resist the American advance and gave the leadership a face-saving reason to end the war. I would say this is conjecture, but several members of the court clique and military leadership actually wrote in their diaries that the bombs were “good luck” or the like. Here’s former Prime Minister Yonai:

I think the term is perhaps inappropriate, but the atomic bombs and the Soviet entry into the war are, in a sense, gifts from the gods [tenyu, also “heaven-sent blessings”]. This way we don’t have to say that we quit the war because of domestic circumstances. I’ve long been advocating control of our crisis, but neither from fear of an enemy attack nor because of the atomic bombs and the Soviet entry into the war. The main reason is my anxiety over the domestic situation. So, it is rather fortunate that we can now control matters without revealing the domestic situation. (Page 509)

Regardless of why exactly it came about, the end of the war brought with it the problem of trying war criminals. Dr. Bix alleges that there was a large-scale conspiracy amongst Japan’s civilian and military leadership to hide all evidence of Hirohito’s war responsibility, a conspiracy aided and abetted by General Douglas McArthur.

Hirohito and MacArthur

The general was supreme commander of the allied occupation forces and had broad powers to govern Japan as he saw fit. Dr. Bix believes that in Hirohito, McArthur saw a symbol he could use to govern more effectively. I’m not sure if I was entirely convinced of a conspiracy – a very good conspiracy leaves the same evidence as no conspiracy at all – but it is undeniable that the defenses of the “Class A” war criminals (the civilian and military leadership charged with crimes against peace) were different from the defenses offered at Nuremburg, in a way that was both curious and most convenient for Hirohito.

Both sets of war criminals (in Tokyo and Nuremburg) tried to deny the legitimacy of “crimes against the peace” and claim their trials were just victor’s justice. But notably absent from all of the trials of Japanese leaders was the defense of “just following orders” that was so emblematic of the Nazis tried at Nuremburg. Unlike the Nazis, the Japanese criminals were quite happy to take responsibility. It was always them, never the emperor. I don’t think this is just a case of their leader having survived; I doubt the Nuremburg defendants would have been so loyal if Hitler had lived.

Of course, there is a potential parsimonious explanation for everyone having their stories straight. Hirohito could have been entirely innocent. Except, if Hirohito was so innocent, how can we explain the testimony Konoe made to one of his aides?

Fumimaro Konoe was the last prime minister before the Pearl Harbour attack and an opponent of war with the United States. He refused to take part in the (alleged) cover up. He was then investigated for war crimes and chose to kill himself. Of Hirohito, he said:

“Of course His Imperial Majesty is a pacifist and he wished to avoid war. When I told him that to initiate war was a mistake, he agreed. But the next day, he would tell me: ‘You were worried about it yesterday but you do not have to worry so much.’ Thus, gradually he began to lead to war. And the next time I met him, he leaned even more to war. I felt the Emperor was telling me: ‘My prime minister does not understand military matters. I know much more.’ In short, the Emperor had absorbed the view of the army and the navy high commands.” (Page 419)

Alas, this sort of damning testimony was mostly avoided at the war crimes trials. With Konoe dead and the rest of Japan’s civilian and military leadership prepared to do whatever it took to exonerate Hirohito, the emperor was safe. Hirohito was never indicted for war crimes, despite his role in authorizing the war and delaying surrender as he searched for a great victory.

Some of the judges were rather annoyed by the lack of indictment. The chief judge wrote: “no ruler can commit the crime of launching aggressive war and then validly claim to be excused for doing so because his life would otherwise have been in danger… It will remain that the men who advised the commission of a crime, if it be one, are in no worse position than the man who directs the crime be committed”.

This didn’t stop most of the judges from passing judgement on the criminals they did have access to. Some of the conspirators paid for their loyalty with their lives. The remainder were jailed. None of them spent much more than a decade in prison. By 1956, all of the “Class A” war criminals except the six who were executed and three who died in jail were pardoned.

The business and financial elite, two groups which profited immensely from the war got off free and clear. None of them were even charged. Dr. Bix suggests that General McArthur vetoed it. He had a country to run and couldn’t afford the disruption that would be caused if all of the business and financial elite were removed.

This leaves the Class B and Class C war criminals, the officers who were charged with more normal war crimes. Those officers who were tried in other countries were much more likely to face execution. Of the nearly 6,000 Class B and Class C war criminals charged outside of Japan, close to 1,000 were executed. A similar number were acquitted. Most of the remainder served limited criminal sentences.

Perhaps the greatest injustice of all was the fate of Unit 731. None of them were ever charged, despite carrying out bacteriological research on innocent civilians. They bought their freedom with research data the Americans coveted.

For all that their defenses differed from the Nuremburg criminals, the Japanese war criminals tried in Tokyo faced a similar fate. A few of them were executed, but most of them served sentences that belied the enormity of their crimes. Life imprisonments didn’t stick and pardons were forthcoming once the occupation ended. And as in Germany, some of the war criminals even ended up holding positions in government. Overall, the sentences gave the impression that in 1945, wars of aggression were much less morally troubling than bank robberies.

I had thought the difficulties Germany faced in denazification – and holding former Nazi’s accountable – were unique. This appears to be false. It seems to be very difficult to maintain the political will to keep war criminals behind bars after an occupation ends, as long as their crimes were not committed against their own people.

In light of this, I think it can be moral to execute war criminals. While I generally oppose the death penalty, this opposition is predicated on there being a viable alternative to execution for people who have flagrantly violated the social contract. Life imprisonment normally provides this, but I no longer believe that it can in the case of war criminals.

The Allies bear some of the blame for the clemency war criminals received. Japan’s constitution required them to seek approval from a majority of the nations that participated in the Tokyo trial. Ultimately, a majority of the eleven nations that were involved in the tribunal put improved ties with Japan over moral principles and allowed clemency to be granted. This suggests that even jailing war criminals outside their country of origin or requiring foreign consent for their pardon can be ineffective.

With both of these options removed, basic justice (and good incentive structures) seem to require all major war criminals to be executed. A rule of thumb is probably to execute any war criminal who would have otherwise be sentenced to twenty years or more of prison. It’s only these prisoners who stand to see their sentence substantially reduced in the inevitable round of pardons.

I also believe that convicted war criminals (as a general class) probably shouldn’t be trusted with the running of a country. To be convicted of war crimes proves that you are likely to flagrantly violate international norms. While people can change, past behaviour remains the best predictor of future behaviour. Therefore, it makes sense to try and remove any right war criminals might otherwise have to hold public office in a way that is extremely difficult to reverse. This could take the form of constitutional amendments that requires all victimized countries to consent to each individual war criminal that wishes to later hold public office, or other similarly difficult to circumvent mechanisms.

This is one area where the International Criminal Court (ICC) could prove its worth. If the ICC is able to deliver justice and avoid bowing to political pressure in any of its cases, then the obvious way of dealing with war criminals would be to send them to the ICC.

The section of the book that covers the war crimes trials and post-war Japan is called “The Unexamined Life”. I think the title is apt. There’s no evidence that Hirohito ever truly grappled with his role in the war, whatever it was. At one point, in response to a question about his war responsibility, Hirohito even said: “I can’t answer that question because I haven’t thoroughly studied the literature in this field”. This answer would be risible even if Hirohito were completely blameless. If there was anyone who knew how much responsibility Hirohito bore for the war, it was the man himself.

In the constitution promulgated by the occupying Americans, Hirohito became a constitutional monarch in truth. Dr. Bix reports that Hirohito was miffed to find that he could no longer appoint prime ministers and cabinets. He adjusted poorly to his lack of role and spent most of the fifties and sixties hoping that he could be made politically useful again. This never happened, although some conservative prime ministers did go to him for advice from time to time. His one consolation was the extra-constitutional military and intelligence briefings he received, but this was a far nod from the amount of information he received during the war.

Ultimately, the only punishment that Hirohito faced was his irrelevance. That is, I think, too small a price to pay for launching (or at the very least, approving) wars of aggression that killed millions of people.

The last section of the book also includes the only flaw I noticed: Dr. Bix cites a poll where 57% of the population (of Japan) thought Hirohito bore war responsibility or were unsure whether he did. Dr. Bix goes on to claim that this implies that Hirohito’s evasive answers were out of step with the opinion of the majority of the Japanese population. I think (although I can’t prove; the original source is Japanese) that this is probably obscuring the truth.

Assuming that a decent fraction of the respondents were unsure, then we’re looking at a plurality (43%) of Japanese believing Hirohito bore no responsibility and smaller fractions unsure and believing he did. If at least 14% of the respondents were unsure (common for polls like this), then you could flip the stance of Dr. Bix’s sentence and have just as much proof. This sort of thing is a common enough tactic of people who want to stretch their data a bit further than it’s worth.

This shades into the larger issue of trust. How much should I trust Dr. Bix? He obviously knows a lot more about Hirohito than I do and he can speak and read Japanese (I cannot). This makes this book more authoritative than previous books by Americans that relied entirely on translations of Japanese scholarship, but it also makes verifying his sources more difficult.

I was able to find critiques of the book by Japanese scholars. That said, skimming through the titles of other works by the scholars has me fairly convinced that they come from the vein of Japanese conservatism that is rife with war apologism and historical revisionism.

On a whole, this has left me somewhat unsatisfied. I’m convinced that Hirohito was more than a harmless puppet leader. I’m also convinced he didn’t wield absolute power. By Dr. Bix’s own admission, he acted contrary to his own wants very often. For me, this doesn’t jibe with autocratic power. My best interpretation of Dr. Bix’s research is that Hirohito was an influential member of one organ of the Japanese state. He wielded significant but not total influence over national policy. I do not believe that Hirohito was as free to act as Dr. Bix claims he was.

I do believe Dr. Bix when he says that Hirohito’s role expanded as the war went on. If nothing else, he became the most experienced of all of Japan’s leaders at the same time as the myth of his divinity and benevolence became most entrenched. Furthermore, Hirohito and his retinue were most free to act when the army and navy were at loggerheads. This became more and more common after 1937.

Dr. Bix actually posits that these disagreements were the ultimate reason that Hirohito could grasp real power. The cabinet (which included civilian, army, and navy decision makers) was supposed to work by consensus. Where there were deep divisions, they would paper over them with vague statements and false consensus, without engaging in the give and take of negotiation that real consensus requires. Since everything was done in Hirohito’s name, he and the court group could twist the vague statements towards their preferred outcomes – all the while pretending Hirohito was a mere constitutional monarch promulgating decisions based on the advice of the cabinet.

This system was horribly inefficient and at least one person tried to reform it. Unfortunately, their “reform” would have led to a military dictatorship. Here’s a quote about the troubles facing one of the pre-war prime ministers:

“Right-wing extremists and terrorists repeatedly assailed him verbally, while the leading reformer in his own party, Mori, sought to break up the party system itself and ally with the military to create a new, more authoritarian political order.” (Page 247)

I’m used to seeing “reformers” only applied positively, but if you’re willing to look at reform as “the process of making the government run more effectively”, I suppose that military dictatorships are one type of reform. I think it’s good to be reminded that efficiency is not the only axis on which we should judge a government. It may be quite reasonable to oppose reforms that will streamline the government when those reforms come at the cost of other values, like fairness, transparency, and freedom of speech.

It’s my habit to try and draw lessons from the history I read. Because Dr. Bix’s book covers so troubled a time, I did not find it lacking in lessons. But I had hoped for something more than lessons from the past. I had hoped to know definitively how much of the fault for Japan’s role in World War II should lie at the feet of Hirohito.

Despite this being the whole purpose of the book, I was left disappointed. It is almost as if Dr. Bix let his indignation with Hirohito’s escape from any and all justice get the better of him. Hirohito and the Making of Modern Japan tried to pin almost every misdeed during Hirohito’s reign on the emperor personally. In overreaching, it left me unsure of how much of itself to believe. I cannot discount it entirely, but I also cannot accept wholesale.

It doesn’t help that Dr. Bix paints a portrait of the emperor so intimate as to humanize him. While Dr. Bix seems to want us to view Hirohito as evil, I could not help but see him as a flawed man following a flawed morality. As far as I can tell, Hirohito would have been happiest as a moderately successful marine biologist. But marine biology is not what was asked of him and unfortunately, he did what he saw as his duty.

Here I again wish to make a comparison with Eichmann in Jerusalem. Had Hirohito not been singularly poor at introspection, or had he not had “an inability to think, namely, to think from the standpoint of somebody else” (while Hannah Arendt said this about Adolf Eichmann, I think it applies equally well to Hirohito), Hirohito could have risen above the failings in his moral education and acted as a brake on Japanese militarism.

Hirohito did not do this. And because of his actions (and perhaps more importantly, his inaction), terrible things came to pass.

The possibility for individuals to do terrible things despite having no malice in their hearts is what caused Hannah Arendt to coin the phrase “the banality of evil”. Fifty years later, we still expect the worst deeds humans can commit to only come from the hands of monsters. There is certainly security in that assumption. When we believe terrible things can only be done deliberately and with malice, we allow ourselves to ignore the possibility that we may be involved in unjust systems or complicit in terrible deeds.

It’s only when we remember that terrible things require no malice, that one may do them even while being a normal person or while acting in accordance with the values they were raised with, that we can properly introspect about our own actions. It is vital that we all take the time to ask “are we the baddies?” and ensure that our ethical systems fail gracefully.

Obviously, Hirohito did none of this. That’s all on him. No matter how you cut the blame pie, Hirohito did nothing to stop the Rape of Nanjing, the attack on Pearl Harbour, the Bataan Death March,  and the forced massed suicides of Okinawans. Hirohito demonstrated that he had the power to order a surrender. Yet he did not do this when the war was all but lost and Japanese cities were bombed daily. He delayed surrender time and again, hoping for some other option that would allow him to cling to whatever scraps of power he had.

For all that Dr. Bix failed to convince me that Hirohito was one of the primary architects of the war, he did convince me that Hirohito bore a large measure of responsibility. I agree that Hirohito should have been a Class A war criminal. I agree that Hirohito escaped all but the faintest touch of justice for his role in the war. And I agree that Hirohito’s escape from justice has made it more difficult for Japan to accept the guilt it should bear for its wars of aggression.

Pump Six and the Perils of Speculative Fiction

I just finished Pump Six, a collection of short stories by Paolo Bacigalupi. A few weeks prior to this, I read Ted Chiang’s short story collection, Stories of Your Life and Others and I couldn’t help but be struck by the contrast between them. Ted Chiang writes stories about different ways the world could work. Paolo Bacigalupi writes stories about different ways the future could happen.

These are two very different sorts of speculation. The first requires extreme attention to detail in order to make the setting plausible, but onceyou clear that bar, you can get away with anything. Ted Chiang is clearly a master at this. I couldn’t find any inconsistencies to pick at in any of his stories.

When you try to predict the future – especially the near future – you don’t need to make up a world out of whole cloth. Here it’s best to start with plausible near future events and let those give your timeline a momentum, carrying you to where you want to go on a chain of reason. No link has to be perfect, but each link has to be plausible. If any of them leave your readers scratching their heads, then you’ve lost them.

Predicting the future is also vulnerable to the future happening. Predictions are rooted in their age and tend to tell us more about the context in which they were made than about the future.

I think Pump Six is a book where we can clearly see and examine both of these problems.

First, let’s talk about chains of events. The stories The Fluted Girl, The Calorie Man, The Tamarisk Hunter, and Yellow Card Man all hinge on events that probably seem plausible to Bacigalupi, but that feel deeply implausible to me.

The Fluted Girl imagines the revival of feudalism in America. Fiefs govern the inland mountains, while there is a democracy (presumably capitalist) on the coasts. This arrangement felt unstable and unrealistic to me.

Feudal societies tend to have much less economic growth than democracies (see part 2 of Scott’s anti-reactionary FAQ). Democracies also aren’t exactly great at staying calm about atrocities right on their doorsteps. These two facts combined make me wonder why the (Coloradan?) feudal society in The Fluted Girl hasn’t been smashed by its economically (and therefore, inevitably militarily) more powerful neighbours.

In The Tamarisk Hunter, the Colorado River is slowly being covered by a giant concrete straw, a project that has been going on for a while and requires massive amounts of resources. The goal is to protect the now diminished Colorado River from evaporation as it winds its way into a deeply drought-stricken California.

In the face of a bad enough drought, every bit counts. But there are much more cost effective ways to get your drinking water. The Colorado river today has an average discharge of 640m3/s. In a bad drought, this would be lower. Let’s say it’s at something like 200m3/s.

You could get that amount of water from building about 100 desalination plants, which would cost something like $100 billion today (using a recently built plant in California as a baseline). Bridges cost something like $3,000 per m2 (using this admittedly flawed report for guidance), so using bridges to estimate the cost, the “straw” would cost about $300 million per kilometer (using the average width of the Colorado river). Given the relative costs of the two options, it is cheaper to replace the whole river (assuming reduced flow from the drought) with desalination plants than it is to build even 330km (<200 miles) of straw.

A realistic response to a decades long California drought would involve paying farmers not to use water, initiating water conservation measures, and building desalination plants. It wouldn’t look like violent conflict over water rights up and down the whole Colorado River.

In The Calorie Man and Yellow Card Man, bioengineered plagues have ravaged the world and oil production has declined to the point where the main source of energy is once again the sun (via agriculture). Even assuming peak oil will happen (more on that in a minute), there will always be nuclear power. Nuclear power plants currently provide for only ten percent of the world’s energy needs, but there’s absolutely no good reason they couldn’t meet basically all of them (especially if combined with solar, hydro, wind, and if necessary, coal).

With improved uranium enrichment techniques and better energy storage technology, it’s plausible that sustainable energy sources could, if necessary, entirely displace oil, even in the transportation industry.

The only way to get from “we’re out of oil” to “I guess it’s back to agriculture as our main source of energy” is if you forget about (or don’t even consider) nuclear power.

This is why I think the stories in Pump Six tell me a lot more about Bacigalupi than about the future. I can tell that he cares deeply about the planet, is skeptical of modern capitalism, and fearful of the damage industrialization, fossil fuels, and global warming may yet bring.

But the story that drove home his message for me wasn’t any of the “ecotastrophes”, where humans are brought to the brink of destruction by our mistreatment of the planet. It was The People of Sand and Slag that made me stop and wonder. It asks us to consider what we’d lose if we poison the planet while adapting to the damage. Is it okay if beaches are left littered with oil and barbed wire if these no longer pose us any threat?

I wish more of the stories had been like that, instead of infected with the myopia that causes environmentalists to forget about the existence of nuclear power (when they aren’t attacking it) and critics of capitalism to assume that corporations will always do the evil thing, with no regard to the economics of the situation.

Disregard for economics and a changing world intersect when Bacigalupi talks about peak oil. Peak oil was in vogue among environmentalists in the 2000s as oil prices rose and rose, but it was never taken seriously by the oil industry. As per Wikipedia, peak oil (as talked about by environmentalists in the ’00s, not as originally formulated) ignored the effects of price on supply and demand, especially in regard to unconventional oil, like the bitumen in the Albertan Oil Sands.

Price is really important when it comes to supply. Allow me to quote from one of my favourite economics stories. It’s about a pair of Texan brothers who (maybe) tried to corner the global market for silver and in the process made silver so unaffordable that Tiffany’s ran an advertisement denouncing them in the third page of the New York Times. The problems the Texans ran into as silver prices rose are relevant here:

But as the high prices persisted, new silver began to come out of the woodwork.

“In the U.S., people rifled their dresser drawers and sofa cushions to find dimes and quarters with silver content and had them melted down,” says Pirrong, from the University of Houston. “Silver is a classic part of a bride’s trousseau in India, and when prices got high, women sold silver out of their trousseaus.”

Unfortunately for the Hunts, all this new supply had a predictable effect. Rather than close out their contracts, short sellers suddenly found it was easier to get their hands on new supplies of silver and deliver.

“The main factor that has caused corners to fail [throughout history] is that the manipulator has underestimated how much will be delivered to him if he succeeds [at] raising the price to artificial levels”

By the same token, many people underestimated the amount of oil that would come out of the woodwork if oil prices remained high – arguably artificially high, no thanks to OPEC – for a prolonged period. As an aside, it’s also likely that we underestimate the amount of unconventional water that could be found if prices ever seriously spiked, another argument against the world in The Tamarisk Hunter.

This isn’t to say that there won’t be a peak in oil production. The very real danger posed by global warming and the fruits of investments in alternative energy when oil prices were high will slowly wean us off of oil. This formulation of peak oil is much different than the other one. A steady decrease in demand for oil  will be hard on oil producing regions, but it won’t come as a sharp shock to the whole world economic order.

I don’t know how much of this could have been known in 2005, especially to anyone deeply embedded in the environmentalist movement. As an exoneration, that’s wonderful. But this is exactly my point from above. You can try and predict the future, but you can only predict from your flawed vantage point. In retrospect, it is often easier to triangulate the vantage point than to see the imagined future as plausible.

Another example: almost all science fiction before the late 00s drastically underestimated the current prevalence in mobile devices. In series that straddle the divide, you often see mobile devices mentioned much more in the latter books, as authors adjust their visions of the future to take into account what they now know in the present.

Writing is hard and the critic will always have an easier time than the author. I don’t mean to be so hard on Bacigalupi, I really did enjoy Pump Six and it’s caused me to do no end of thinking and discussing since I finished reading it. In this regard, it was an immensely successful book.

The Pitfalls of One-Man Rule

In light of the leaks about Michael Flynn, just about everyone, from America’s allies to its intelligence officers, seems to be reconsidering how much intelligence they share with Donald Trump’s White House. I can’t think of anything more damaging to President Trump’s ability to govern than various domestic and allied agencies (semi-)publicly mulling whether or not to share information with him.

It’s not that I think this will cause irreparable damage to his public image. At this point, you can be swayed by other people’s opinion of Trump or you can’t. Trump’s base doesn’t care what a bunch of intelligence geeks in suits think about him. They just want to see jobs come back.

It’s just that Trump is already beginning to experience one of the most significant failure modes of single-person rule: isolation.

One of the little talked about virtues of democracy is how its decentralizing tendency makes isolation of key decision makes much more difficult. Take Canada as an example. There are 338 Members of Parliament, each based in a different geographic region and expected to regularly travel there and respond to the concerns of the local residents. Each MP also has several aides, responsible for briefing them and keeping them in the loop. Cabinet Ministers have all of this, plus they’ll have one or two MPs acting as their assistants in matters of their portfolio. Prime Minister Justin Trudeau is accountable to his constituents, his cabinet, his MPs, and through them, all of Canada.

It is very difficult to influence Mr. Trudeau’s decision making by influencing the information he receives. Government agencies can attempt it, but Mr. Trudeau is broadly popular, which makes this much more difficult. To hide information from a leader, you need a quorum. While this can be accomplished by a vocal minority, it becomes very difficult to gather even this in the face of enthusiastic majority support.

In addition, the diverse information channels Mr. Trudeau has access to mean that he is very likely to hear about any notable news that leaks out a department, even if his chief of staff or one of his cabinet ministers doesn’t want him to.

This has the effect of making power struggles somewhat transparent. In general, power among the elites is apportioned based on the results of elections and measured in terms of Members of Parliament and political capital (or, more concretely, opinion polling and what this means for re-election chances). All of this information is a matter of public record. Anyone who wants to know what elite faction is currently dominant and how much political capital it has left can find this out with a simple Google search.

On the other end of the spectrum, we have the Vatican. Pope Francis was elected through an opaque process and few Catholics saw his election coming. The power games of the cardinals are hidden from most congregants and their reasons for voting how they do are between them and their god. Francis will reign until he dies or steps down, but the power games of the elites (read: the cardinals) haven’t stopped. Instead of jockeying for position directly, they will jockey by trying to control the flow of information to Francis. If one group of cardinals succeeds (or even partially succeeds), they will wield significant invisible influence.

This same sort of opacity is what makes the “science” of Kremlinology appealing. Without clear information, it takes a hundred subtle hints to figure out who has power (and perhaps even more critically, who is being listened to by those with power).

Right now, it seems like Donald Trump is in a situation that is closer to the Pope than the Prime Minister of Canada.

This normally isn’t the case for presidents. They’re deeply embedded in the fabric of a party and have multiple channels for information – as well as multiple factions they depend on for support. Trump lacks both history and (in his mind, at least) dependency. The route of last resort for information to travel to the president is through donors. Trump has closed off this route by believing he’s entirely self-made.

All of this means that Trump is at serious risk of being controlled by one or two influential advisors. If this happens, there really are limited options for his party to bring him back in line and coordinate on a legislative agenda if the interests of those advisors don’t align with the interests of the Republican party.

This is what should be keeping congressional Republicans up at night. Trump should be staying up at night wondering about what his agencies are refusing to tell him.

Governments have to rely on veritable armies of analysts to keep them swimming in the data they need to act. You want to launch an airstrike on a suspected terrorist? You’re going to need a dozen people to correlate a hundred small tidbits of information to positively identify them with enough time to spare to launch a cruise missile or a drone.

These people tend not to be that loyal to any particular party (at least when it comes to how they do their job). While the heads of departments are often political appointees, their deputies are career men and women who have come up through the civil service. Whatever they lack in loyalty to parties, they make up for in loyalty to the system. This is generally enough to allay any fears about them hiding information or failing to perform their role.

Enter Donald Trump, who seems like he might just try and rip the whole system down around their ears. Do you think they’re going to stand for that? If you can’t believe that they have conviction and a genuine loyalty to the system, at least believe that they have some instinct for self-preservation. Career civil servants rely on the system for a paycheck, after all.

Imagine you’re an intelligence officer, fairly high up. You know how much of a threat Russia is. You’ve been watching them for a decade and you’ve seen how they’re gobbling up territory along their borders, trying to reclaim some slice of their lost empire. You think Trump is going to give some of the intelligence you just collected to Russia, blowing the cover of a source or two. So, you hide it. It’s easy enough to do. All you really have to do is flag it as routine, not pass it up the chain of command. It’s almost the same as phoning it in, really.

Imagine you are Trump. Intelligence is drying up. What do you do? You can go yell at your CIA Department head (who might be loyal to you). He or she can go yell at some subordinates. And they’ll promise to do better. They might, for a week or two, or they might not. Maybe you start getting more intelligence, but it’s all of terrible quality.

What do you do? What can you do?

In the end, Trump is one man. He has maybe a hundred people who are personally loyal to him. If we’re generous, we might call it 150. But I think we have to cap it at Dunbar’s number. He can’t count on an unbroken chain of personal loyalty either, because there is a disconnect between the career civil servants and the political appointees.

Trump and all of his henchmen can rant and rail all they want. But at the end of the day, they can’t compel. They can’t hold guns to the heads of every CIA analyst and demand they tell the administration everything they know. They can’t even fire them all. You can’t solve an intelligence shortage by getting rid of all your intelligence analysts. At a certain point, you just have to give up.

Think I’m exaggerating? Think this couldn’t possibly work on Trump? Read Eichmann in Jerusalem and you’ll learn it worked on the Nazis. Where open resistance failed, obstructionism and carefully cultivated laziness succeeded.

Power is in many ways an illusion and a fragile one at that. Break it and you might not be able to put it back together. If Trump threatens the CIA (or any other agency; you can also image the DoJ taking forever to close an investigation or the EPA having a bunch of trouble finishing an inspection and giving an all clear) and fails to deliver on his threat (likely), then the jig is up. He’s lost all ability to change anyone’s behaviour through threats.

So, this is the problem Trump faces. He has the presidency and he intends to use it to make sweeping changes to America. But without close cooperation with lawmakers, his term is going to look a lot like an attempt at one-man rule. Certainly, this should be frightening for everyone who cares about checks and balances in America.

But it should also frighten Trump’s supporters. One man rule is a terrible system of government. If Trump makes a serious go at it, his cabinet and advisors will be at each other’s throats (when he isn’t around) in next to no time and he’ll face persistent (but impossible to end) resistance from almost every Federal department. I don’t know how exactly Trump plans to make America great again, but I bet he isn’t prepared for large scale passive resistance.

The final remaining question then is: will this resistance show up, or are the early rumours exaggerated. On this point, the world is watching and hoping that the ordinary civil servants of America display the requisite moral courage to passively resist Trump’s most damaging requests.

Thoughts (and Data) on Charity & Taxes

The other day, I posed a question to my friends on Facebook:

Do you think countries with higher taxes see more charitable donations or fewer charitable donations? What sort of correlation would you expect between the two (weak positive? weak negative? strong positive? strong negative?).

I just crunched some numbers and I’ll post them later. First I want to give people a chance to guess and test their calibration.

I was doing research for a future blog post on libertarianism and wanted to check one of the fundamental assumptions that many libertarians make: in the absence of a government, private charity would provide many of the same social services that are currently provided by the government.

I honestly wasn’t sure what I’d find. But I was curious to see what people would suggest. Answer fell into four main camps:

  1. Charitable giving and support for a welfare state might be caused by the same thing, so there will be a weak positive correlation.
  2. Tax incentives for charitable donations shift the utility of donating, such that people in higher tax countries will donate more, as they get more utility per dollar spent (they get the same good feelings from charity, but also receive a bigger rebate come tax time). People who thought up this mechanism predicted a weak positive correlation.
  3. This whole thing will be hopeless confounded by other variables and no conclusion would survive proper controls.
  4. Libertarians are right. Taxes drain money that would go to private charity, so we should see a strong(ish) negative correlation.

I was surprised (but probably shouldn’t have been) to find that these tracked people’s political views. The more libertarian I thought someone was, the more likely they were to believe in a negative correlation. Meanwhile, people who were really into the welfare state tended to assume that charitable donations and taxes would be correlated.

In order to figure out who was right, I grabbed the most recent World Giving Index and correlated it with data about personal income tax levels (and sales tax levels, just to see what happened).

There are a number of flaws with this analysis. I’m not looking for confounding variables. Like at all. When it comes to things as tied to national character as charity and taxes (and how they interact!), this is a serious error in the analysis. I’m also using pretty poor metrics. It would be best to compare something like average tax rate with charitable donation amount per capita. Unfortunately, I couldn’t find any good repositories of this data and didn’t want to spend the hours it would take to build a really solid database of my own.

I decided to restrict my analysis to OECD countries (minus Turkey, which I was missing data on). You’ll have to take my word that I made this decision before I saw any of the data (it turns out that there is essentially no correlation between income tax rate and percent of people who donate to charity when looking at all countries where I have data for both).

Caveats aside, what did I see?

There was a weak correlation (I’m using a simple Pearson correlation, as implemented by Google sheets here, nothing fancy) between the percentage of a population that engaged in charitable giving and the highest income tax bracket in a country. There was a weaker, negative correlation between sales tax and the percent of a population that engaged in charitable giving, but more than 60% of this came from the anchoring effect of the USA, with its relatively high charitable giving and lack of Federal sales tax. The correlation with income tax rates wasn’t similarly vulnerable to removing the United States (in fact, it jumped up by about 12% when they were removed).

Here’s the graphs. I’ve deliberately omitted trend lines because I’m a strong believer in the constellation test.

 

All the data available is in a publicly viewable Google Sheet.

I don’t think these data give a particularly clear answer about the likelihood of private charity replacing government sponsored welfare programs in a hypothetical libertarian state. But they do suggest to me that the burden of proof should probably rest on libertarians. These results should make you view any claims that charitable giving is held back by the government with skepticism, but it should by no means prevent you from being convinced by good evidence.

I am happy to see that my results largely line up with better academic studies (as reported by the WSJ). It seems that if we look at the past few decades, decreasing the tax rates in the highest income brackets have been associated with decreasing charitable giving, at least in the United States. Whether this represents a correlated increase in selfishness, or fewer individuals donating as the utility of donating decreases is difficult to know.

The WSJ article also mentions that government grants to a charity reduce private donation by about 75% of the grant amount. I don’t know if this represents donations that are lost entirely, or merely substituted for other (presumably needier) charities. If it’s the first, then this would be strong evidence for the libertarian perspective. If it’s the latter, then it means that many people intuitively understand and accept the key effective altruism concept of “room for more funding“, at least as far as the government is concerned.

Conclusions

Finding good answers to the question of whether private charity would replace government welfare turned out to be harder than I thought. The main problem was the quality of data that is easily available. While it was easy to find statistics good enough for a simple, limited analysis, I wasn’t able to find a convenient table with all of the data I needed. This is where actual researchers have a huge advantage over random people on the internet. They have access to cheap labour in the volumes necessary to find and tabulate high quality data.

I’m very glad I posed the question to my friends before figuring out the answer. It never occurred to me to consider the effect of tax incentives on charitable giving. I’m now of the weakly held opinion that the main way taxes affect charitable donations is by offsetting the costs with rebates. I’m also fascinated by the extent to which people’s guesses tracked their political leanings. This shows that (on my Facebook wall, at least) people hold opinions that are motivated by a genuine desire to see the most effective possible government. Differing axioms and exposure to different data lead to differing conceptions of what this would be, but everyone is ultimately on the same team.

I will try and remember this next time I think someone’s preferred government policy is a terrible idea. It’s probably much more productive to try and figure out why they believe their policy objectives will lead to the best outcomes and arguing about that, rather than slipping into clichéd insults.

I was also reminded that it’s fun and rewarding to spend a few hours doing data analysis (especially when you get the same results as studies that get reported on in the WSJ).

Ethics, Politics, Quick Fix

Don’t confuse constitutional rights with social norms

When Ken over at Popehat gets into a full-on rant about people who don’t understand rights, I’m often sympathetic. It was Ken who made me understand that people who don’t understand rights are a threat to everyone. When many people are misinformed about their rights, those rights become easier to take away.

When Scott at Slate Star Codex talks about good social norms, I’m very keen to listen. Scott helped me understand that social groups are worth cultivating and that it’s a good idea to think about how your group norms will change your experience of interacting with people.

So, when Tessa linked me to a Slate Star Codex post where Scott disagreed with Ken, I had some thinking to do.

The Slate Star Codex post is a response to a piece Ken put up after the furor around Justine Sacco’s tweets a few years back. Ken is defending the right of everyone else on Twitter to say whatever they like in response to Justine Sacco’s thoughtless tweets. The particular part Scott highlights is:

The phrase “the spirit of the First Amendment” often signals approaching nonsense. So, regrettably, does the phrase “free speech” when uncoupled from constitutional free speech principles. These terms often smuggle unprincipled and internally inconsistent concepts — like the doctrine of the Preferred First Speaker. The doctrine of the Preferred First Speaker holds that when Person A speaks, listeners B, C, and D should refrain from their full range of constitutionally protected expression to preserve the ability of Person A to speak without fear of non-governmental consequences that Person A doesn’t like. The doctrine of the Preferred First Speaker applies different levels of scrutiny and judgment to the first person who speaks and the second person who reacts to them; it asks “why was it necessary for you to say that” or “what was your motive in saying that” or “did you consider how that would impact someone” to the second person and not the first. It’s ultimately incoherent as a theory of freedom of expression.

Scott disagrees. He argues that there is a spirit of the First Amendment and it’s summed up by Eliezer Yudkowsky with: “Bad argument gets counterargument. Does not get bullet. Never. Never ever never for ever.”

Scott asks to imagine at what point damaging responses become appropriate:

What does “bullet” mean in the quote above? Are other projectiles covered? Arrows? Boulders launched from catapults? What about melee weapons like swords or maces? Where exactly do we draw the line for “inappropriate responses to an argument”?

Scott’s eventual line in the sand is: “Bad argument gets counterargument. Does not get bullet. Does not get doxxing. Does not get harassment. Does not get fired from job. Gets counterargument. Should not be hard.”

I’m sympathetic to what Scott was trying to do here, but ultimately, I’m on the side of Ken.

Scott wants to talk about the spirit of the First Amendment, which is fine. But the spirit he wants to read into it is divorced from the reality of constitutional rights. The First Amendment, like many of the rights in the US Constitution, is a negative right – it prevents the government from acting in a certain way, rather than saying it must provide people with a certain thing. The US Government can’t stop you from saying what you want, but it has no obligation to make you heard. If everyone ignores you, the government will not intervene.

It’s pretty weird to try and read a positive spirit into a negative right. The framers of the Bill of Rights knew when the rights they were setting down were negative rights. They understood the difference between negative and positive rights. To claim that the spirit of a definitely negative right is actually positive feels like an unfair attempt to halo a set of normative ethics (or perhaps aesthetics) with the positive affect that many Americans hold for their constitution.

As far as the government is concerned, as long as people are debating and silencing through legal means, there actually isn’t a distinction between trying to debate and trying to silence. Neither type of speech can be stopped. And I think it’s trivially easy to come up with examples for why neither should be stopped as a matter of routine (if you need inspiration, think of what your worst political enemies call “hate speech” and shudder about it being banned).

Luckily, negative speech and association rights and the government monopoly on force means that it is really hard to credibly threaten people’s freedom of association, so Scott is free to build a subculture that shares his beliefs about normative ethics. A subculture is free to demand positive rights for all members within the context of subculture related discussions and has free association as the perfect tool for enforcing it.

I’m glad that this is what rationalists are trying to do and I like our subculture and all, but we can’t claim that our weird norms are universal positive rights. I know this is a common thing for subcultures to do, but it’s embarrassing.
