Terminal and Non-terminal Punishments

What happens if you don’t pay your taxes?

I’ve never actually tried this, but I’m pretty sure the sequence of events goes like this:

  • The government sends you a letter saying "hey, you really should pay your taxes".
  • The government sends you a few more letters, just in case you forgot about the first.
  • The government sends police to your house to inform that you have been charged with tax evasion.
  • If you continue to refuse to pay your taxes, a judge finds you guilty of tax evasion.
  • If you still refuse to pay, a judge sends you to jail.

Here jail is the terminal punishment. Demands 1-4 above are backed up by threat of jail1. But there is no threat that gets you to go to jail; if you refuse, armed men and women will drag you there by force (and a...

The Nixon Problem

Richard Nixon would likely have gone down in history as one of America’s greatest presidents, if not for Watergate.

To my mind, his greatest successes were détente with China and the end of the convertibility of dollars into gold, but he also deserves kudos for ending the war in Vietnam, continuing the process of desegregation, establishing the EPA, and signing the anti-ballistic missile treaty.

Nixon was willing to try unconventional solutions and shake things up. He wasn’t satisfied with leaving things as they were. This is, in some sense, a violation of political norms.

When talking about political norms, it’s important to separate them into their two constituent parts.

First, there are the norms of policy. These are the standard terms of the debate. In some countries, they may look like a (semi-)durable centrist consensus. In others they may require accepting single-party rule as a given.

Second are the...

Post-modernism and Political Diversity

I was reading a post-modernist critique of capitalist realism – the resignation to capitalism as the only practical way to organize a society, arising out of the failure of the Soviet Union – and I was struck by something interesting about post-modernism.

Insofar as post-modernism stands for anything, it is a critique of ideology. Post-modernism holds that there is no privileged lens with which to view the world; that even empiricism is suspect, because it too has a tendency to reproduce and reify the power structures in which in exists.

A startling thing then, is the sterility of the post-modernist political landscape. It is difficult to imagine a post-modernist who did not vote for Bernie Sanders or Jill Stein. Post-modernism is solely a creature of the left and specifically that part of the left that rejects the centrist compromise beloved of the incrementalist or market left.

The Character of Leaders is the Destiny of Nations

The fundamental problem of governance is the misalignment between means and ends. In all practically achievable government systems, the process of acquiring and maintaining power requires different skills than the exercise of power. The core criteria of any good system of government, therefore, must be selecting people by a metric that bears some resemblance to governing, or perhaps more importantly, having a metric that actively filters out people who are not suited to govern.

When the difference between means and ends becomes extreme, achieving power serves only to demonstrate unsuitability for holding it. Such systems are inevitably doomed to collapse.

Many people (I am thinking most notably of neo-reactionaries) put too much stock in the incentives or institutions of government systems. Neo-reactionaries look at the institutions of monarchies and claim they lead to stability, because monarchs have a large personal incentive to improve their kingdom and their lifetime tenure should...

The Fifty Percent Problem

Brexit was always destined to be a shambles.

I haven’t written much about Brexit. It’s always been a bit of a case of “not my monkeys, not my circus”. And we’ve had plenty of circuses on this side of the Atlantic for me to write about.

That said, I do think Brexit is useful for illustrating the pitfalls of this sort of referendum, something I’ve taken to calling “The 50% Problem”.

When QALYs Are Wrong – Thoughts on the Gates Foundation

Every year, I check in to see if we’ve eradicated polio or guinea worm yet. Disease eradications are a big deal. We’ve only successfully eradicated one disease – smallpox – so being so close to wiping out two more is very exciting.

Still, when I looked at how much resources were committed to polio eradication (especially by the Gates Foundation), I noticed they seemed incongruent with its effects. No polio eradication effort can be found among GiveWell’s top charities, because it is currently rather expensive to prevent polio. The amount of quality-adjusted life years (QALYs, a common measure of charity effectiveness used in the Effective Altruism community) you can save with a donation to preventing malaria is just higher than for polio.

I briefly wondered if it might not be better for all of the effort going to polio eradication to instead go to anti-malaria programs. After...

Why External Debt is so Dangerous to Developing Countries

I have previously written about how to evaluate and think about public debt in stable, developed countries. There, the overall message was that the dangers of debt were often (but not always) overhyped and cynically used by certain politicians. In a throwaway remark, I suggested the case was rather different for developing countries. This post unpacks that remark. It looks at why things go so poorly when developing countries take on debt and lays out a set of policies that I think could help developing countries that have high debt loads.

The very first difference in debt between developed and developing countries lies in the available terms of credit; developing countries get much worse terms. This makes sense, as they’re often much more likely to default on their debt. Interest scales with risk and it just is riskier to lend money to Zimbabwe than to Canada.

But interest payments...

Against Novelty Culture

So, there’s this thing that happens in certain intellectual communities, like (to give a totally random example) social psychology. This thing is that novel takes are rewarded. New insights are rewarded. Figuring out things that no one has before is rewarded. The high-status people in such a community are the ones who come up with and disseminate many new insights.

On the face of it, this is good! New insights are how we get penicillin and flight and Pad Thai burritos. But there’s one itty bitty little problem with building a culture around it.

Good (and correct!) new ideas are a finite resource.

This isn’t news. Back in 2005, John Ioannidis laid out the case for “most published research findings” being false. It turns out that when you have a small chance of coming up with a correct idea even using statistical tests for to find false positives can...

Hidden Disparate Impact

It is against commonly held intuitions that a group can be both over-represented in a profession, school, or program, and discriminated against. The simplest way to test for discrimination is to look at the general population, find the percent that a group represents, then expect them to represent exactly that percentage in any endeavour, absent discrimination.

Harvard, for example, is 17.1% Asian-American (foreign students are broken out separately in the statistics I found, so we’re only talking about American citizens or permanent residents in this post). America as a whole is 4.8% Asian-American. Therefore, many people will conclude that there is no discrimination happening against Asian-Americans at Harvard.

This is what would happen under many disparate impact analyses of discrimination, where the first step to showing discrimination is showing one group being accepted (for housing, employment, education, etc.) at a lower rate than another.

Science Is Less Political Than Its Critics

A while back, I was linked to this Tweet:

It had sparked a brisk and mostly unproductive debate. If you want to see people talking past each other, snide comments, and applause lights, check out the thread. One of the few productive exchanges centres on bridges.

Bridges are clearly a product of science (and its offspring, engineering) – only the simplest bridges can be built without scientific knowledge. Bridges also clearly have a political dimension. Not only are bridges normally the product of politics, they also are embedded in a broader political fabric. They change how a space can be used and change geography.

Hacked Pacemakers Won’t Be This Year’s Hot Crime Trend

Or: the simplest ways of killing people tend to be the most effective.

A raft of articles came out during Defcon showing that security vulnerabilities exist in some pacemakers, vulnerabilities which could allow attackers to load a pacemaker with arbitrary code. This is obviously worrying if you have a pacemaker implanted. It is equally self-evident that it is better to live in a world where pacemakers cannot be hacked. But how much worse is it to live in this unfortunately hackable world? Are pacemaker hackings likely to become the latest crime spree?

Electrical grid hackings provide a sobering example. Despite years of warning that the American electrical grid is vulnerable to cyber-attacks, the greatest threat to America’s electricity infrastructure remains… squirrels.

Hacking, whether it’s of the electricity grid or of pacemakers gets all the headlines. Meanwhile fatty foods and squirrels do all the real damage.

You Shouldn’t Believe In Technological Unemployment Without Believing In Killer AI

As interest in how artificial intelligence will change society increases, I’ve found it revealing to note what narratives people have about the future.

Some, like the folks at MIRI and OpenAI, are deeply worried that unsafe artificial general intelligences – an artificial intelligence that can accomplish anything a person can – represent an existential threat to humankind. Others scoff at this, insisting that these are just the fever dreams of tech bros. The same news organizations that bash any talk of unsafe AI tend to believe that the real danger lies in robots taking our jobs.

Let’s express these two beliefs as separate propositions:

  1. It is very unlikely that AI and AGI will pose an existential risk to human society.
  2. It is very likely that AI and AGI will result in widespread unemployment.

Can you spot the contradiction between these two statements? In the common imagination, it would require an AI that can approximate human capabilities to drive significant unemployment. Given that humans are the largest existential risk to other humans (think thermonuclear war and climate change), how could equally intelligent and capable beings, bound to subservience, not present a threat?

Why does surgery have such ineffective safety regulation?

Did you know that half of all surgical complications are preventable? In the US alone, this means that surgeons cause between 50,00 and 200,000 preventable deaths each year.

Surgeons are, almost literally, getting away with murder.

Why do we let them? Engineers who see their designs catastrophically fail often lose their engineering license, even when they’re found not guilty in criminal proceedings. If surgeons were treated like engineers, many of them wouldn’t be operating anymore.

Indeed, the death rate in surgery is almost unique among regulated professions. One person has died in a commercial aviation accident in the US in the last nine years. Structural engineering related accidents killed at most 251 people in the US in 20161 and only approximately 4% of residential structure failures in the US occur due to deficiencies in design2.

The Biggest Tech Innovation is Selling Club Goods

Economists normally splits goods into four categories:

  • Public goods are non-excludable (so anyone can access them) and non-rival (I can use them as much as I want without limiting the amount you can use them). Broadcast television, national defense, and air are all public goods.
  • Common-pool resources are non-excludable but rival (if I use them, you will have to make do with less). Iron ore, fish stocks, and grazing land are all common pool resources.
  • Private goods are excludable (their access is controlled or limited by pricing or other methods) and rival. My clothes, computer, and the parking space I have in my lease but never use are all private goods.
  • Club goods are excludable but (up to a certain point) non-rival. Think of the swimming pool in an apartment building, a large amusement park, or cellular service.

Sanderson’s Law Applies To Cultures Too

For the uninitiated, Sanderson’s Law (technically, Sanderson’s First Law of Magic) is:

An author's ability to solve conflict with magic is DIRECTLY PROPORTIONAL to how well the reader understands said magic.

Brandon Sanderson wrote this law to help new writers come up with satisfying magical systems. But I think it’s applicable beyond magic. A recent experience has taught me that it’s especially applicable to fantasy cultures.

I recently read Sunset Mantle by Alter S. Reiss, a book that falls into one of my favourite fantasy sub-genres: hopeless siege tales.

Context Windows

When you’re noticing that you’re talking past someone, what does it look like? Do you feel like they’re ignoring all the implications of the topic at hand (“yes, I know the invasion of Iraq is causing a lot of pain, but I think the important question is, ‘did they have WMDs?’”)?

Does Amateurish Writing Exist

[Warning: Spoilers for Too Like the Lightning]

What marks writing as amateurish (and whether “amateurish” or “low-brow” works are worthy of awards) has been a topic of contention in the science fiction and fantasy community for the past few years, with the rise of Hugo slates and the various forms of “puppies”.

I’m not talking about the learning works of genuine amateurs. These aren’t stories that use big words for the sake of sounding smart (and at the cost of slowing down the stories), or over the top fanfiction-esque rip-offs of more established works (well, at least not since the Wheel of Time nomination in 2014).

The Awkward Dynamics of the Conservative Leadership Debates

Tanya Granic Allen is the most idealistic candidate I’ve ever seen take the stage in a Canadian political debate. This presents some awkward challenges for the candidates facing her, especially Mulroney and Elliot.

First, there’s the simple fact of her idealism. I think Granic Allen genuinely believes everything she says. For her, knowing what’s right and what’s wrong is simple. There isn’t a whole lot of grey. She even (bless her) probably believes that this will be an advantage come election time. People overwhelming don’t like the equivocation of politicians, so Granic Allen must assume her unequivocal moral stances will be a welcome change

For many people, it must be. Even for those who find it grating, it seems almost vulgar to attack her. It’s clear that she isn’t in this for herself and doesn’t really care about personal power. Whether she could maintain that innocence in the face of...

Not Just Zoning: Housing Prices Driven By Beauty Contests

No, this isn’t a post about very pretty houses or positional goods. It’s about the type of beauty contest described by John Maynard Keynes.

Imagine a newspaper that publishes one hundred pictures of strapping young men. It asks everyone to send in the names of the five that they think are most attractive. They offer a prize: if your selection matches the five men most often appearing in everyone else’s selections, you’ll win $500.

You could just do what the newspaper asked and send in the names of those men that you think are especially good looking. But that’s not very likely to give you the win. Everyone’s tastes are different and the people you find attractive might not be very attractive to anyone else. If you’re playing the game a bit smarter, you’ll instead pick the five people that you think have the broadest appeal.

Against Job Lotteries

In simple economic theory, wages are supposed to act as signals. When wages increase in a sector, it should signal people that there’s lots of work to do there, incentivizing training that will be useful for that field, or causing people to change careers. On the flip side, when wages decrease, we should see a movement out of that sector.

This is all well and good. It explains why the United States has seen (over the past 45 years) little movement in the number of linguistics degrees, a precipitous falloff in library sciences degrees, some decrease in English degrees, and a large increase in engineering and business degrees1.

Improvement Without Superstition

When you make continuous, incremental improvements to something, one of two things can happen. You can improve it a lot, or you can fall into superstition. I’m not talking about black cats or broken mirrors, but rather humans becoming addicted to whichever steps were last seen to work, instead of whichever steps produce their goal.

I’ve seen superstition develop first hand. It happened in one of the places you might least expect it – in a biochemistry lab. In the summer of 2015, I found myself trying to understand which mutants of a certain protein were more stable than the wildtype.

Four Narratives on Mohammed Bin Salman

Since June 21st of this year, Mohammed bin Salman (often known by his initials, MBS) has been the crown prince of Saudi Arabia. This required what was assuredly not a palace coup, because changes of government or succession are never coups, merely “similar to coups”, “coup-like”, “coup-esque”, or “coupLite™” 1. As crown prince, MBS has championed a loosening of religious restrictions on women and entertainment, a decrease in reliance on oil for state revenues, and a harder line with Qatar and Iran.

Media coverage has been, uh, split. Here’s an editorial in The Washington Post comparing MBS to Putin, while an editorial in The New York Times fawningly declares “Saudi Arabia’s Arab Spring, at Last”2. Given that there’s so much difference in opinion on MBS, I thought it might be useful to...

When Remoter Effects Matter

In utilitarianism, “remoter effects” are the result of our actions influencing other people (and are hotly debated). I think that remoter effects are often overstated, especially (as Sir Williams said in Utilitarianism for and against) when they give the conventionally ethical answer. For example, a utilitarian might claim that the correct answer to the hostage dilemma1 is to kill no one, because killing weakens the sanctity of human life and may lead to more deaths in the future.

When debating remoter effects, I think it’s worthwhile to split them into two categories: positive and negative. Positive remoter effects are when your actions cause others to refrain from some negative action they might otherwise take. Negative remoter effects are when your actions make it more likely that others will engage in a negative action2.

Warriors and Soldiers

In 2006, Dr. Atul Gawande wrote an article in The New Yorker about maternal care entitled “How Childbirth Went Industrial”. It’s an excellent piece from an author who consistently produces excellent pieces. In it, Gawande charts the rise of the C-section, from its origin as technique so dangerous it was considered tantamount to murder (and consequently banned on living mothers), to its current place as one of the most common surgical procedures carried out in North American hospitals.

The Graph Model of Conflict Resolution – Sensitivity Analysis

Last week, I used the Graph Model of Conflict Resolution to find a set of stable equilibria in the present conflict between North Korea and the USA. They were:

  • The tense status quo (s. 0)
  • An American troop withdrawal, paired with North Korea giving up its nuclear weapons (s.10)
  • All out conventional warfare on the Korean Peninsula (s. 4)
  • All out nuclear warfare on the Korean Peninsula (s. 5)

But how much can we trust these results? How much to they depend on my subjective ranking of the belligerent’s preferences? How much do they depend on the stability metrics I used?

The Graph Model of Conflict Resolution – Introduction

Why do things happen the way they do?

Every day, there are conflicts between decision makers. These occur on the international scale (think the Cuban Missile Crisis), the provincial level (Ontario’s sex-ed curriculum anyone?) and the local level (Toronto’s bike lane kerfuffle). Conflict is inevitable. Understanding it, regrettably, is not.

The final results of many conflicts can look baffling from the outside. Why did the Soviet Union retreat in the Cuban missile crisis? Why do some laws pass and others die on the table?

The most powerful tool I have for understanding the ebb and flow of conflict is the Graph Model of Conflict Resolution (GMCR). I had the immense pleasure of learning about it under the tutelage of Professor Keith Hipel, one of its creators. Over the next few weeks, I’d like to share it with you.

Regulation Revisited

Previously I described regulation as a regressive tax. It may not kill jobs per se, but it certainly shifts them towards people with university degrees, largely at the expense of those without. I’m beginning to rethink that position; I’m increasingly worried that many types of regulation are actually leading to a net loss of jobs. There remains a paucity of empirical evidence on this subject. Today I’m going to present a (I believe convincing) model of how regulations could kill jobs, but I’d like to remind everyone that models are less important than evidence and should only be the focus of discussion in situations like this, where the evidence is genuinely sparse.

Living Beyond Your Time Means

[3 minute read]

Most of us are familiar with what it looks like when someone we know is living beyond their means. Expensive vacations, meals, or possessions pile up, accompanied by a veritable mountain of credit card debt. People fall into the horrible habit of paying one credit card off with another and get punished by punitive credit card interest rates.

If someone lives beyond their means for years, they may never be able to retire. Only frantic work keeps them just ahead of the tsunami of debt.

People living beyond their means often have a higher material standard of living then their friends. They have a nicer house, nicer cars, take nicer vacations and eat out more. But they tend to be more stressed out. Every month they have to figure out how to make ends meet.

For people who like possessions and don’t mind stress, it can be...

They don’t hate your values; they just assign them no weight

Previously, I talked about akrasia as one motive for socially conservative legislation. I think the akrasia model is useful when explaining certain classes of seemingly hypocritical behaviour, but it’s far from the only reason for social conservatives to push for legislation that liberals oppose. At least some legislation comes from a desire to force socially conservative values on everyone1.

Liberals are terrible at understanding the values underlying conservative legislation. When an anti-abortion single issue voter took a reproductive rights seminar at Yale, he was surprised to hear that many of his classmates believed that anti-abortion laws were aimed entirely at controlling women’s sexuality, rather than stopping the (to his eyes) moral crime of abortion2.

Socially Conservative Legislation as Akrasia Managment

If you hang out with people obsessed with self-improvement, one term that you’ll hear a lot is akrasia. A dictionary will tell you that akrasia means “The state of mind in which someone acts against their better judgement through weakness of will.”

Someone who struggles with it will have more visceral stories. “It’s like someone else is controlling me, leaving me powerless to stop watching Netflix” is one I’ve often heard. Or “I know that scrolling through Facebook for five hours is against my goals, but I just can’t help myself”.

Meditations on Regulation, or the Case of the $10,000 Staircase

Breaking news: a retired mechanic spent one afternoon and $550 building a staircase. This is news because the City of Toronto said it would cost $65,000 for them to do it. They’ve since walked back that estimate, claiming it won’t be that expensive (instead, the final cost looks to be a mere $10,000).

Part of this is materials and labour. The city will probably go for something a bit more permeant than wood – probably concrete or metal – and will probably have higher labour costs (the mechanic hired a random guy off the street to help out, which is probably against city procurement policy). But a decent part (perhaps even the majority) of the increased costs will be driven by regulation.

First there’s the obvious compliance activities: site assessment, community consultation, engineering approval, insurance approval. Each of these will take the...

Minimum Standards or Broad Access?

There are two sides to every story. Zoning and maximum occupancy regulations are exclusionary and drive up the price of housing. They are also necessary to prevent exploitative landlords from leaving their tenants in squalor. Catastrophic health insurance plans leave patients uncovered for many of the services they might need. They’re also often the only plans that are rational for younger people to buy.

Where you come down on either of these – or any similar cases where there’s a clear trade-off between maximum access and minimum standards – is probably heavily dependent on your situation. If you’re an American millennial without an employer-provided or parental health care plan, you’re probably quite incensed about the lack of catastrophic health care insurance. For healthy young adults, those plans were an excellent deal.

Similarly, workaholics in the Bay Area sometimes want to...

To have lobbyists on your side

There is perennial debate in Canada about whether we should allow a “two-tiered” healthcare system. The debate is a bit confusing – by many measures we already have a two-tiered system, with private clinics and private insurance – but ultimately hinges on the ability of doctors to mix fees. Currently it is illegal for a doctor to charge anything on top of the provincially mandated fee structure. If the province is willing to pay $3,000 for a procedure, you cannot charge $5,000 and ask your patients (or their insurance) to make up the difference.

Supporters of a mixed system argue that it will alleviate wait times for everyone. Detractors argue that it will create a cumbersome, unfair system and paradoxically increase wait times. It’s enough to convince me that I don’t know what the fuck a two-tier healthcare system would have as its first order effects.

Some thoughts on Canadian “family values” conservatives

I’d like to expand on one of the points I raised yesterday about Canadian social conservatives and the sorts of things they can expect from Andrew Scheer, because I think the Canadian approach to “family values” conservatism is desperately under-theorized.

Yesterday I claimed that the main way that Harper pushed so-called family values was through economic incentives to have a 1950s-style nuclear family. Both income splitting and the Universal Child Care Benefit were designed to make it more feasible to have a single income family.

This is a radically different tack than taken by American family values candidates, who primarily exercise their beliefs by banning sex education, fighting against gay marriage and adoption, and restricting access to abortion1. The American approach attempts to close off all alternatives but a heterosexual, monogamous, child-producing marriage. The Canadian approach is to bribe people into this (and to...

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...

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...

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.

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...

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 once you 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...

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...

Checks and balances can’t last if they make governing impossible

There is an interesting post by Professor Bryan Caplan spinning limited government as an insurance policy against wild swings in political climate. You should go read the whole thing, but I’ll summarize for the lazy.

Professor Caplan makes his case using a thought experiment with an angel. This angel talks to you during Obama’s inauguration and offers you a bargain. The terms are simple If you accept, neither Obama nor Trump will be able to get much done. You trade away Obamacare and in exchange you don’t get Trump’s immigration policies. Professor Caplan frames this as a form of political insurance, a guarantee of mediocracy instead of potentially wild swings.

Professor Caplan points out that this insurance (which might be sounding pretty tempting to you right about now) is actually similar to the concept of limited government, something we already know how to achieve.

On Political Norms and Scandals

Prime Minister Justin Trudeau rang in 2017 with an ethics scandal. Electoral reform and President Trump might have pushed it out of the news, but it still bears talking about.

Maybe it’s just that my memory is fuzzy before 2004, but I feel like there was a point in Canadian politics when scandals weren’t a run of the mill occurrence. It seems like we’ve been treated to a non-stop parade of them since the sponsorship scandal. There was the In-and-Out scandal, that time Maxime Bernier left classified documents with his Hell’s Angels girlfriend, that horrible mess with Afghan detainees, the Robocalls (and associated criminal charges!), the F-35s, the senate, and now the Aga Khan.

There’s also been a host of minor scandals that didn’t even make it into this list, like the $50 million of G8 money spent to make Tony Clement’s...

Trump is Marius, not Caesar

Yonatan Zunger has an article in Medium claiming that the immigration executive order from last Friday is the “trial balloon” for a planned Trump coup. I don’t think this is quite correct. While I no longer have much confidence that America will still be a democracy in 50 years, I don’t think Trump will be its first dictator.

I do think the first five points in Dr. Zunger’s analysis are fairly sound. I’m not sure if they are true, but they’re certainly plausible. It is true, for example, that it is unusual to file papers for re-election so quickly. Barack Obama didn’t file his re-election form until 2011. Whether this means that Trump will use campaign donations to enrich his family remains to be seen, but the necessary public disclosures of campaign expenses make this falsifiable. Give it a year and we’ll know.

Unfortunately, the 6th point is much...

Levels of Reading or: How I Learned to Stop Worrying and (Occasionally) Love Literary Fiction

Annoyed with me describing If on a winter’s night a traveller as “very literary” one too many times, my partner Tessa challenged me to explain what I meant by “literary”.

This presented a problem, because I’ve been using literary as a shorthand for “that type of book that people who review books for a living get really excited about but I never seem to like” – basically as a category label, not as a descriptive phrase. Even worse, If on a winter’s night a traveller didn’t really fit into the category anyway; it’s a book that I’m heartily enjoying.

To answer Tessa’s question, I had to abandon using “literary” as a category label and instead treat it as a handle for a concept. But first, I needed a concept.
