Terrible but not likely, likely but not terrible

May 17 JDN 2458985

The human brain is a remarkably awkward machine. It’s really quite bad at organizing data, relying on associations rather than formal categories.

It is particularly bad at negation. For instance, if I tell you that right now, no matter what, you must not think about a yellow submarine, the first thing you will do is think about a yellow submarine. (You may even get the Beatles song stuck in your head, especially now that I’ve mentioned it.) A computer would never make such a grievous error.

The human brain is also quite bad at separation. Daniel Dennett coined a word “deepity” for a particular kind of deep-sounding but ultimately trivial aphorism that seems to be quite common, which relies upon this feature of the brain. A deepity has at least two possible readings: On one reading, it is true, but utterly trivial. On another, it would be profound if true, but it simply isn’t true. But if you experience both at once, your brain is triggered for both “true” and “profound” and yields “profound truth”. The example he likes to use is “Love is just a word”. Well, yes, “love” is in fact just a word, but who cares? Yeah, words are words. But love, the underlying concept it describes, is not just a word—though if it were that would change a lot.

One thing I’ve come to realize about my own anxiety is that it involves a wide variety of different scenarios I imagine in my mind, and broadly speaking these can be sorted into two categories: Those that are likely but not terrible, and those that are terrible but not likely.

In the former category we have things like taking an extra year to finish my dissertation; the mean time to completion for a PhD is over 8 years, so finishing in 6 instead of 5 can hardly be considered catastrophic.

In the latter category we have things like dying from COVID-19. Yes, I’m a male with type A blood and asthma living in a high-risk county; but I’m also a young, healthy nonsmoker living under lockdown. Even without knowing the true fatality rate of the virus, my chances of actually dying from it are surely less than 1%.

But when both of those scenarios are running through my brain at the same time, the first triggers a reaction for “likely” and the second triggers a reaction for “terrible”, and I get this feeling that something terrible is actually likely to happen. And indeed if my probability of dying were as high as my probability of needing a 6th year to finish my PhD, that would be catastrophic.

I suppose it’s a bit strange that the opposite doesn’t happen: I never seem to get the improbability of dying attached to the mildness of needing an extra year. The confusion never seems to trigger “neither terrible nor likely”. Or perhaps it does, and my brain immediately disregards that as not worthy of consideration? It makes a certain sort of sense: An event that is neither probable nor severe doesn’t seem to merit much anxiety.

I suspect that many other people’s brains work the same way, eliding distinctions between different outcomes and ending up with a sort of maximal product of probability and severity.
The solution to this is not an easy one: It requires deliberate effort and extensive practice, and benefits greatly from formal training by a therapist. Counter-intuitively, you need to actually focus more on the scenarios that cause you anxiety, and accept the anxiety that such focus triggers in you. I find that it helps to actually write down the details of each scenario as vividly as possible, and review what I have written later. After doing this enough times, you can build up a greater separation in your mind, and more clearly categorize—this one is likely but not terrible, that one is terrible but not likely. It isn’t a cure, but it definitely helps me a great deal. Perhaps it could help you.

Darkest Before the Dawn: Bayesian Impostor Syndrome

Jan 12 JDN 2458860

At the time of writing, I have just returned from my second Allied Social Sciences Association Annual Meeting, the AEA’s annual conference (or AEA and friends, I suppose, since there several other, much smaller economics and finance associations are represented as well). This one was in San Diego, which made it considerably cheaper for me to attend than last year’s. Alas, next year’s conference will be in Chicago. At least flights to Chicago tend to be cheap because it’s a major hub.

My biggest accomplishment of the conference was getting some face-time and career advice from Colin Camerer, the Caltech economist who literally wrote the book on behavioral game theory. Otherwise I would call the conference successful, but not spectacular. Some of the talks were much better than others; I think I liked the one by Emmanuel Saez best, and I also really liked the one on procrastination by Matthew Gibson. I was mildly disappointed by Ben Bernanke’s keynote address; maybe I would have found it more compelling if I were more focused on macroeconomics.

But while sitting through one of the less-interesting seminars I had a clever little idea, which may help explain why Impostor Syndrome seems to occur so frequently even among highly competent, intelligent people. This post is going to be more technical than most, so be warned: Here There Be Bayes. If you fear yon algebra and wish to skip it, I have marked below a good place for you to jump back in.

Suppose there are two types of people, high talent H and low talent L. (In reality there is of course a wide range of talents, so I could assign a distribution over that range, but it would complicate the model without really changing the conclusions.) You don’t know which one you are; all you know is a prior probability h that you are high-talent. It doesn’t matter too much what h is, but for concreteness let’s say h = 0.50; you’ve got to be in the top 50% to be considered “high-talent”.

You are engaged in some sort of activity that comes with a high risk of failure. Many creative endeavors fit this pattern: Perhaps you are a musician looking for a producer, an actor looking for a gig, an author trying to secure an agent, or a scientist trying to publish in a journal. Or maybe you’re a high school student applying to college, or a unemployed worker submitting job applications.

If you are high-talent, you’re more likely to succeed—but still very likely to fail. And even low-talent people don’t always fail; sometimes you just get lucky. Let’s say the probability of success if you are high-talent is p, and if you are low-talent, the probability of success is q. The precise value depends on the domain; but perhaps p = 0.10 and q = 0.02.

Finally, let’s suppose you are highly rational, a good and proper Bayesian. You update all your probabilities based on your observations, precisely as you should.

How will you feel about your talent, after a series of failures?

More precisely, what posterior probability will you assign to being a high-talent individual, after a series of n+k attempts, of which k met with success and n met with failure?

Since failure is likely even if you are high-talent, you shouldn’t update your probability too much on a failurebut each failure should, in fact, lead to revising your probability downward.

Conversely, since success is rare, it should cause you to revise your probability upward—and, as will become important, your revisions upon success should be much larger than your revisions upon failure.

We begin as any good Bayesian does, with Bayes’ Law:

P[H|(~S)^n (S)^k] = P[(~S)^n (S)^k|H] P[H] / P[(~S)^n (S)^k]

In words, this reads: The posterior probability of being high-talent, given that you have observed k successes and n failures, is equal to the probability of observing such an outcome, given that you are high-talent, times the prior probability of being high-skill, divided by the prior probability of observing such an outcome.

We can compute the probabilities on the right-hand side using the binomial distribution:

P[H] = h

P[(~S)^n (S)^k|H] = (n+k C k) p^k (1-p)^n

P[(~S)^n (S)^k] = (n+k C k) p^k (1-p)^n h + (n+k C k) q^k (1-q)^n (1-h)

Plugging all this back in and canceling like terms yields:

P[H|(~S)^n (S)^k] = 1/(1 + [1-h/h] [q/p]^k [(1-q)/(1-p)]^n)

This turns out to be particularly convenient in log-odds form:

L[X] = ln [ P(X)/P(~X) ]

L[(~S)^n) (S)^k|H] = ln [h/(1-h)] + k ln [p/q] + n ln [(1-p)/(1-q)]

Since p > q, ln[p/q] is a positive number, while ln[(1-p)/(1-q)] is a negative number. This corresponds to the fact that you will increase your posterior when you observe a success (k increases by 1) and decrease your posterior when you observe a failure (n increases by 1).

But when p and q are small, it turns out that ln[p/q] is much larger in magnitude than ln[(1-p)/(1-q)]. For the numbers I gave above, p = 0.10 and q = 0.02, ln[p/q] = 1.609 while ln[(1-p)/(1-q)] = -0.085. You will therefore update substantially more upon a success than on a failure.

Yet successes are rare! This means that any given success will most likely be first preceded by a sequence of failures. This results in what I will call the darkest-before-dawn effect: Your opinion of your own talent will tend to be at its very worst in the moments just preceding a major success.

I’ve graphed the results of a few simulations illustrating this: On the X-axis is the number of overall attempts made thus far, and on the Y-axis is the posterior probability of being high-talent. The simulated individual undergoes randomized successes and failures with the probabilities I chose above.

Bayesian_Impostor_full

There are 10 simulations on that one graph, which may make it a bit confusing. So let’s focus in on two runs in particular, which turned out to be run 6 and run 10:

[If you skipped over the math, here’s a good place to come back. Welcome!]

Bayesian_Impostor_focus

Run 6 is a lucky little devil. They had an immediate success, followed by another success in their fourth attempt. As a result, they quickly update their posterior to conclude that they are almost certainly a high-talent individual, and even after a string of failures beyond that they never lose faith.

Run 10, on the other hand, probably has Impostor Syndrome. Failure after failure after failure slowly eroded their self-esteem, leading them to conclude that they are probably a low-talent individual. And then, suddenly, a miracle occurs: On their 20th attempt, at last they succeed, and their whole outlook changes; perhaps they are high-talent after all.

Note that all the simulations are of high-talent individuals. Run 6 and run 10 are equally competent. Ex ante, the probability of success for run 6 and run 10 was exactly the same. Moreover, both individuals are completely rational, in the sense that they are doing perfect Bayesian updating.

And yet, if you compare their self-evaluations after the 19th attempt, they could hardly look more different: Run 6 is 85% sure that they are high-talent, even though they’ve been in a slump for the last 13 attempts. Run 10, on the other hand, is 83% sure that they are low-talent, because they’ve never succeeded at all.

It is darkest just before the dawn: Run 10’s self-evaluation is at its very lowest right before they finally have a success, at which point their self-esteem surges upward, almost to baseline. With just one more success, their opinion of themselves would in fact converge to the same as Run 6’s.

This may explain, at least in part, why Impostor Syndrome is so common. When successes are few and far between—even for the very best and brightest—then a string of failures is the most likely outcome for almost everyone, and it can be difficult to tell whether you are so bright after all. Failure after failure will slowly erode your self-esteem (and should, in some sense; you’re being a good Bayesian!). You’ll observe a few lucky individuals who get their big break right away, and it will only reinforce your fear that you’re not cut out for this (whatever this is) after all.

Of course, this model is far too simple: People don’t just come in “talented” and “untalented” varieties, but have a wide range of skills that lie on a continuum. There are degrees of success and failure as well: You could get published in some obscure field journal hardly anybody reads, or in the top journal in your discipline. You could get into the University of Northwestern Ohio, or into Harvard. And people face different barriers to success that may have nothing to do with talent—perhaps why marginalized people such as women, racial minorities, LGBT people, and people with disabilities tend to have the highest rates of Impostor Syndrome. But I think the overall pattern is right: People feel like impostors when they’ve experienced a long string of failures, even when that is likely to occur for everyone.

What can be done with this information? Well, it leads me to three pieces of advice:

1. When success is rare, find other evidence. If truly “succeeding” (whatever that means in your case) is unlikely on any given attempt, don’t try to evaluate your own competence based on that extremely noisy signal. Instead, look for other sources of data: Do you seem to have the kinds of skills that people who succeed in your endeavors have—preferably based on the most objective measures you can find? Do others who know you or your work have a high opinion of your abilities and your potential? This, perhaps is the greatest mistake we make when falling prey to Impostor Syndrome: We imagine that we have somehow “fooled” people into thinking we are competent, rather than realizing that other people’s opinions of us are actually evidence that we are in fact competent. Use this evidence. Update your posterior on that.

2. Don’t over-update your posterior on failures—and don’t under-update on successes. Very few living humans (if any) are true and proper Bayesians. We use a variety of heuristics when judging probability, most notably the representative and availability heuristics. These will cause you to over-respond to failures, because this string of failures makes you “look like” the kind of person who would continue to fail (representative), and you can’t conjure to mind any clear examples of success (availability). Keeping this in mind, your update upon experiencing failure should be small, probably as small as you can make it. Conversely, when you do actually succeed, even in a small way, don’t dismiss it. Don’t look for reasons why it was just luck—it’s always luck, at least in part, for everyone. Try to update your self-evaluation more when you succeed, precisely because success is rare for everyone.

3. Don’t lose hope. The next one really could be your big break. While astronomically baffling (no, it’s darkest at midnight, in between dusk and dawn!), “it is always darkest before the dawn” really does apply here. You are likely to feel the worst about yourself at the very point where you are about to finally succeed. The lowest self-esteem you ever feel will be just before you finally achieve a major success. Of course, you can’t know if the next one will be it—or if it will take five, or ten, or twenty more tries. And yes, each new failure will hurt a little bit more, make you doubt yourself a little bit more. But if you are properly grounded by what others think of your talents, you can stand firm, until that one glorious day comes and you finally make it.

Now, if I could only manage to take my own advice….

Pascal’s Mugging

Nov 10 JDN 2458798

In the Singularitarian community there is a paradox known as “Pascal’s Mugging”. The name is an intentional reference to Pascal’s Wager (and the link is quite apt, for reasons I’ll discuss in a later post.)

There are a few different versions of the argument; Yudkowsky’s original argument in which he came up with the name “Pascal’s Mugging” relies upon the concept of the universe as a simulation and an understanding of esoteric mathematical notation. So here is a more intuitive version:

A strange man in a dark hood comes up to you on the street. “Give me five dollars,” he says, “or I will destroy an entire planet filled with ten billion innocent people. I cannot prove to you that I have this power, but how much is an innocent life worth to you? Even if it is as little as $5,000, are you really willing to bet on ten trillion to one odds that I am lying?”

Do you give him the five dollars? I suspect that you do not. Indeed, I suspect that you’d be less likely to give him the five dollars than if he had merely said he was homeless and asked for five dollars to help pay for food. (Also, you may have objected that you value innocent lives, even faraway strangers you’ll never meet, at more than $5,000 each—but if that’s the case, you should probably be donating more, because the world’s best charities can save a live for about $3,000.)

But therein lies the paradox: Are you really willing to bet on ten trillion to one odds?

This argument gives me much the same feeling as the Ontological Argument; as Russell said of the latter, “it is much easier to be persuaded that ontological arguments are no good than it is to say exactly what is wrong with them.” It wasn’t until I read this post on GiveWell that I could really formulate the answer clearly enough to explain it.

The apparent force of Pascal’s Mugging comes from the idea of expected utility: Even if the probability of an event is very small, if it has a sufficiently great impact, the expected utility can still be large.

The problem with this argument is that extraordinary claims require extraordinary evidence. If a man held a gun to your head and said he’d shoot you if you didn’t give him five dollars, you’d give him five dollars. This is a plausible claim and he has provided ample evidence. If he were instead wearing a bomb vest (or even just really puffy clothing that could conceal a bomb vest), and he threatened to blow up a building unless you gave him five dollars, you’d probably do the same. This is less plausible (what kind of terrorist only demands five dollars?), but it’s not worth taking the chance.

But when he claims to have a Death Star parked in orbit of some distant planet, primed to make another Alderaan, you are right to be extremely skeptical. And if he claims to be a being from beyond our universe, primed to destroy so many lives that we couldn’t even write the number down with all the atoms in our universe (which was actually Yudkowsky’s original argument), to say that you are extremely skeptical seems a grievous understatement.

That GiveWell post provides a way to make this intuition mathematically precise in terms of Bayesian logic. If you have a normal prior with mean 0 and standard deviation 1, and you are presented with a likelihood with mean X and standard deviation X, what should you make your posterior distribution?

Normal priors are quite convenient; they conjugate nicely. The precision (inverse variance) of the posterior distribution is the sum of the two precisions, and the mean is a weighted average of the two means, weighted by their precision.

So the posterior variance is 1/(1 + 1/X^2).

The posterior mean is 1/(1+1/X^2)*(0) + (1/X^2)/(1+1/X^2)*(X) = X/(X^2+1).

That is, the mean of the posterior distribution is just barely higher than zero—and in fact, it is decreasing in X, if X > 1.

For those who don’t speak Bayesian: If someone says he’s going to have an effect of magnitude X, you should be less likely to believe him the larger that X is. And indeed this is precisely what our intuition said before: If he says he’s going to kill one person, believe him. If he says he’s going to destroy a planet, don’t believe him, unless he provides some really extraordinary evidence.

What sort of extraordinary evidence? To his credit, Yudkowsky imagined the sort of evidence that might actually be convincing:

If a poorly-dressed street person offers to save 10(10^100) lives (googolplex lives) for $5 using their Matrix Lord powers, and you claim to assign this scenario less than 10-(10^100) probability, then apparently you should continue to believe absolutely that their offer is bogus even after they snap their fingers and cause a giant silhouette of themselves to appear in the sky.

This post he called “Pascal’s Muggle”, after the term from the Harry Potter series, since some of the solutions that had been proposed for dealing with Pascal’s Mugging had resulted in a situation almost as absurd, in which the mugger could exhibit powers beyond our imagining and yet nevertheless we’d never have sufficient evidence to believe him.

So, let me go on record as saying this: Yes, if someone snaps his fingers and causes the sky to rip open and reveal a silhouette of himself, I’ll do whatever that person says. The odds are still higher that I’m dreaming or hallucinating than that this is really a being from beyond our universe, but if I’m dreaming, it makes no difference, and if someone can make me hallucinate that vividly he can probably cajole the money out of me in other ways. And there might be just enough chance that this could be real that I’m willing to give up that five bucks.

These seem like really strange thought experiments, because they are. But like many good thought experiments, they can provide us with some important insights. In this case, I think they are telling us something about the way human reasoning can fail when faced with impacts beyond our normal experience: We are in danger of both over-estimating and under-estimating their effects, because our brains aren’t equipped to deal with magnitudes and probabilities on that scale. This has made me realize something rather important about both Singularitarianism and religion, but I’ll save that for next week’s post.

Revealed preference: Does the fact that I did it mean I preferred it?

Post 312 Oct 27 JDN 2458784

One of the most basic axioms of neoclassical economics is revealed preference: Because we cannot observe preferences directly, we infer them from actions. Whatever you chose must be what you preferred.

Stated so badly, this is obviously not true: We often make decisions that we later come to regret. We may choose under duress, or confusion; we may lack necessary information. We change our minds.

And there really do seem to be economists who use it in this bald way: From the fact that a particular outcome occurred in a free market, they will infer that it must be optimally efficient. (“Freshwater” economists who are dubious of any intervention into markets seem to be most guilty of this.) In the most extreme form, this account would have us believe that people who trip and fall do so on purpose.

I doubt anyone believes that particular version—but there do seem to be people who believe that unemployment is the result of people voluntarily choosing not to work, and revealed preference has also led economists down some strange paths when trying to explain what sure looks like irrational behavior—such as “rational addiction” theory, positing that someone can absolutely become addicted to alcohol or heroin and end up ruining their life all based on completely rational, forward-thinking decision planning.

The theory can be adapted to deal with these issues, by specifying that it’s only choices made with full information and all of our faculties intact that count as revealing our preferences.

But when are we ever in such circumstances? When do we ever really have all the information we need in order to make a rational decision? Just what constitutes intact faculties? No one is perfectly rational—so how rational must we be in order for our decisions to count as revealing our preferences?

Revealed preference theory also quickly becomes tautologous: Why do we choose to do things? Because we prefer them. What do we prefer? What we choose to do. Without some independent account of what our preferences are, we can’t really predict behavior this way.

A standard counter-argument to this is that revealed preference theory imposes certain constraints of consistency and transitivity, so it is not utterly vacuous. The problem with this answer is that human beings don’t obey those constraints. The Allais Paradox, the Ellsberg Paradox, the sunk cost fallacy. It’s even possible to use these inconsistencies to create “money pumps” that will cause people to systematically give you money; this has been done in experiments. While real-world violations seem to be small, they’re definitely present. So insofar as your theory is testable, it’s false.

The good news is that we really don’t need revealed preference theory. We already have ways of telling what human beings prefer that are considerably richer than simply observing what they choose in various scenarios. One very simple but surprisingly powerful method is to ask. In general, if you ask people what they want and they have no reason to distrust you, they will in fact tell you what they want.

We also have our own introspection, as well as our knowledge about millions of years of evolutionary history that shaped our brains. We don’t expect a lot of people to prefer suffering, for instance (even masochists, who might be said to ‘prefer pain’, seem to be experiencing that pain rather differently than the rest of us would). We generally expect that people will prefer to stay alive rather than die. Some may prefer chocolate, others vanilla; but few prefer motor oil. Our preferences may vary, but they do follow consistent patterns; they are not utterly arbitrary and inscrutable.

There is a deeper problem that any account of human desires must face, however: Sometimes we are actually wrong about our own desires. Affective forecasting, the prediction of our own future mental states, is astonishingly unreliable. People often wildly overestimate the emotional effects of both positive and negative outcomes. (Interestingly, people with depression tend not to do this—those with severe depression often underestimate the emotional effects of positive outcomes, while those with mild depression seem to be some of the most accurate forecasters, an example of the depressive realism effect.)

There may be no simple solution to this problem. Human existence is complicated; we spend large portions of our lives trying to figure out what it is we really want.
This means that we should not simply trust that whatever it is happens is what everyone—or even necessarily anyone—wants to happen. People make mistakes, even large, systematic, repeated mistakes. Sometimes what happens is just bad, and we should be trying to change it. Indeed, sometimes people need to be protected from their own bad decisions.

The backfire effect has been greatly exaggerated

Sep 8 JDN 2458736

Do a search for “backfire effect” and you’re likely to get a large number of results, many of them from quite credible sources. The Oatmeal did an excellent comic on it. The basic notion is simple: “[…]some individuals when confronted with evidence that conflicts with their beliefs come to hold their original position even more strongly.”

The implications of this effect are terrifying: There’s no point in arguing with anyone about anything controversial, because once someone strongly holds a belief there is nothing you can do to ever change it. Beliefs are fixed and unchanging, stalwart cliffs against the petty tides of evidence and logic.

Fortunately, the backfire effect is not actually real—or if it is, it’s quite rare. Over many years those seemingly-ineffectual tides can erode those cliffs down and turn them into sandy beaches.

The most recent studies with larger samples and better statistical analysis suggest that the typical response to receiving evidence contradicting our beliefs is—lo and behold—to change our beliefs toward that evidence.

To be clear, very few people completely revise their worldview in response to a single argument. Instead, they try to make a few small changes and fit them in as best they can.

But would we really expect otherwise? Worldviews are holistic, interconnected systems. You’ve built up your worldview over many years of education, experience, and acculturation. Even when someone presents you with extremely compelling evidence that your view is wrong, you have to weigh that against everything else you have experienced prior to that point. It’s entirely reasonable—rational, even—for you to try to fit the new evidence in with a minimal overall change to your worldview. If it’s possible to make sense of the available evidence with only a small change in your beliefs, it makes perfect sense for you to do that.

What if your whole worldview is wrong? You might have based your view of the world on a religion that turns out not to be true. You might have been raised into a culture with a fundamentally incorrect concept of morality. What if you really do need a radical revision—what then?

Well, that can happen too. People change religions. They abandon their old cultures and adopt new ones. This is not a frequent occurrence, to be sure—but it does happen. It happens, I would posit, when someone has been bombarded with contrary evidence not once, not a few times, but hundreds or thousands of times, until they can no longer sustain the crumbling fortress of their beliefs against the overwhelming onslaught of argument.

I think the reason that the backfire effect feels true to us is that our life experience is largely that “argument doesn’t work”; we think back to all the times that we have tried to convince to change a belief that was important to them, and we can find so few examples of when it actually worked. But this is setting the bar much too high. You shouldn’t expect to change an entire worldview in a single conversation. Even if your worldview is correct and theirs is not, that one conversation can’t have provided sufficient evidence for them to rationally conclude that. One person could always be mistaken. One piece of evidence could always be misleading. Even a direct experience could be a delusion or a foggy memory.

You shouldn’t be trying to turn a Young-Earth Creationist into an evolutionary biologist, or a climate change denier into a Greenpeace member. You should be trying to make that Creationist question whether the Ussher chronology is really so reliable, or if perhaps the Earth might be a bit older than a 17th century theologian interpreted it to be. You should be getting the climate change denier to question whether scientists really have such a greater vested interest in this than oil company lobbyists. You can’t expect to make them tear down the entire wall—just get them to take out one brick today, and then another brick tomorrow, and perhaps another the day after that.

The proverb is of uncertain provenance, variously attributed, rarely verified, but it is still my favorite: No single raindrop feels responsible for the flood.

Do not seek to be a flood. Seek only to be a raindrop—for if we all do, the flood will happen sure enough. (There’s a version more specific to our times: So maybe we’re snowflakes. I believe there is a word for a lot of snowflakes together: Avalanche.)

And remember this also: When you argue in public (which includes social media), you aren’t just arguing for the person you’re directly engaged with; you are also arguing for everyone who is there to listen. Even if you can’t get the person you’re arguing with to concede even a single point, maybe there is someone else reading your post who now thinks a little differently because of something you said. In fact, maybe there are many people who think a little differently—the marginal impact of slacktivism can actually be staggeringly large if the audience is big enough.

This can be frustrating, thankless work, for few people will ever thank you for changing their mind, and many will condemn you even for trying. Finding out you were wrong about a deeply-held belief can be painful and humiliating, and most people will attribute that pain and humiliation to the person who called them out for being wrong—rather than placing the blame where it belongs, which is on whatever source or method made you wrong in the first place. Being wrong feels just like being right.

But this is important work, among the most important work that anyone can do. Philosophy, mathematics, science, technology—all of these things depend upon it. Changing people’s minds by evidence and rational argument is literally the foundation of civilization itself. Every real, enduring increment of progress humanity has ever made depends upon this basic process. Perhaps occasionally we have gotten lucky and made the right choice for the wrong reasons; but without the guiding light of reason, there is nothing to stop us from switching back and making the wrong choice again soon enough.

So I guess what I’m saying is: Don’t give up. Keep arguing. Keep presenting evidence. Don’t be afraid that your arguments will backfire—because in fact they probably won’t.

Procrastination is an anxiety symptom

Aug 18 JDN 2458715

Why do we procrastinate? Some people are chronic procrastinators, while others only do it on occasion, but almost everyone procrastinates: We have something important to do, and we should be working on it, but we find ourselves doing anything else we can think of—cleaning is a popular choice—rather than actually getting to work. This continues until we get so close to the deadline that we have no choice but to rush through the work, lest it not get done at all. The result is more stress and lower-quality work. Why would we put ourselves through this?

There are a few different reasons why people may procrastinate. The one that most behavioral economists lean toward is hyperbolic discounting: Because we undervalue the future relative to the present, we set aside unpleasant tasks for later, when it seems they won’t be as bad.

This could be relevant in some cases, particularly for those who chronically procrastinate on a wide variety of tasks, but I find it increasingly unconvincing.

First of all, there’s the fact that many of the things we do while procrastinating are not particularly pleasant. Some people procrastinate by playing games, but even more procrastinate by cleaning house or reorganizing their desks. These aren’t enjoyable activities that you would want to do as soon as possible to maximize the joy.

Second, most people don’t procrastinate consistently on everything. We procrastinate on particular types of tasks—things we consider particularly important, as a matter of fact. I almost never procrastinate in general: I complete tasks early, I plan ahead, I am always (over)prepared. But lately I’ve been procrastinating on three tasks in particular: Revising my second-year paper to submit to journals, writing grant proposals, and finishing my third-year paper. These tasks are all academic, of course; they all involve a great deal of intellectual effort. But above all, they are high stakes. I didn’t procrastinate on homework for classes, but I’m procrastinating on finishing my dissertation.

Another common explanation for procrastination involves self-control: We can’t stop ourselves from doing whatever seems fun at the moment, when we should be getting down to work on what really matters.

This explanation is even worse: There is no apparent correlation between propensity to procrastinate and general impulsiveness—or, if anything, the correlation seems to be negative. The people I know who procrastinate the most consistently are the least impulsive; they tend to ponder and deliberate every decision, even small decisions for which the extra time spent clearly isn’t worth it.

The explanation I find much more convincing is that procrastination isn’t about self-control or time at all. It’s about anxiety. Procrastination is a form of avoidance: We don’t want to face the painful experience, so we stay away from it as long as we can.

This is certainly how procrastination feels for me: It’s not that I can’t stop myself from doing something fun, it’s that I can’t bring myself to face this particular task that is causing me overwhelming stress.

This also explains why it’s always something important that we procrastinate on: It’s precisely things with high stakes that are going to cause a lot of painful feelings. And anxiety itself is deeply linked to the fear of negative evaluation—which is exactly what you’re afraid of when submitting to a journal or applying for a grant. Usually it’s a bit more metaphorical than that, the “evaluation” of being judged by your peers; but here we are literally talking about a written evaluation from a reviewer.

This is why the most effective methods at reducing procrastination all involve reducing your anxiety surrounding the task. In fact, one of the most important is forgiving yourself for prior failings—including past procrastination. Students who were taught to forgive themselves for procrastinating were less likely to procrastinate in the future. If this were a matter of self-control, forgiving yourself should be counterproductive; but in fact it’s probably the most effective intervention.

Unsurprisingly, those with the highest stress level had the highest rates of procrastination (causality could run both ways there); but this is much less true for those who are good at practicing self-compassion. The idea behind self-compassion is very simple: Treat yourself as kindly as you would treat someone you care about.

I am extraordinarily bad at self-compassion. It is probably my greatest weakness. If we were to measure self-compassion by the gap between how kind you are to yourself and how kind you are to others, I would probably have one of the largest gaps in the world. Compassion for others has been a driving force in my life for as long as I can remember, and I put my money where my mouth is, giving at least 8% of my gross income to top-rated international charities every year. But compassion for myself feels inauthentic, even alien; I brutally punish myself for every failure, every moment of weakness. If someone else treated me the way I treat myself, I’d consider them abusive. It’s something I’ve struggled with for many years.

Really, the wonder is that I don’t procrastinate more; I think it’s because I’m already doing most of the things that people will tell you to do to avoid procrastination, like scheduling specific tasks to specific times and prioritizing a small number of important tasks each day. I even keep track of how I actually use my time (I call it “descriptive scheduling”, as opposed to conventional “normative scheduling”), and use that information to make my future schedules more realistic—thus avoiding or at least mitigating the planning fallacy. But when it’s just too intimidating to even look at the paper I’m supposed to be revising, none of that works.

If you too are struggling with procrastination (and odds of that are quite high), I’m afraid that I don’t have any brilliant advice for you today. I can recommend those scheduling techniques, and they may help; but the ultimate cause of procrastination is not bad scheduling or planning but something much deeper: anxiety about the task itself and being evaluated upon it. Procrastination is not laziness or lack of self-control: It’s an anxiety symptom.

I don’t care what happened in that video

Jan 27 JDN 2458511

Right now there is an ongoing controversy over a viral video of a confrontation between young protesters wearing MAGA hats and an elderly Native American man. Various sources are purporting to show “a fuller picture” and “casting new light” and showing “a different side”. Others are saying it’s exactly as bad as it looks.

I think it probably is as bad as it looks, but the truth is: I don’t care. This is a distraction.

If you think litigating the precise events of this video is important, you are suffering from a severe case of scope neglect. You are looking at a single event between a handful of people when you should be looking at the overall trends of a country of over 300 million people.

First of all: The government shutdown only just ended. There are still going to be a lot of pieces to pick up. That’s what we should be talking about. That’s what we should be posting about. That’s what we should be calling Senators about. This is a national emergency. The longer this lasts, the worse it is going to get. People will die because of this shutdown—from tainted food and polluted water and denied food stamps. Our national security is being jeopardized—particularly with regard to cybersecurity.

The shutdown was also a completely unforced error. Government shutdowns shouldn’t even exist, and now that this one is over, we need to change the budget process so that this can never happen again.

And if you want to talk about the racist, sexist, and authoritarian leanings of Trump supporters, that’s quite important too. But it doesn’t hinge upon one person or one confrontation. I’m sure there are Trump supporters who aren’t racist; and I’m sure there are Obama supporters who are. But the overall statistical trend there is extremely strong.

I understand that most people suffer from severe scope neglect, and we have to live in a world filled with such people; so maybe there’s some symbolic value in finding one particularly egregious case that you can put a face on and share with the world. But if you’re going to do that, there’s two things I’d ask of you:

1. Make absolutely sure that this case is genuine. Nothing will destroy your persuasiveness faster than holding up an ambiguous case as if it were definitive.
2. After you’ve gotten their attention with the single example, show the statistics. There are truths, whole truths, and statistics. If you really want to know something, you use statistics.

The statistics are what this is really about. One person, even a hundred people—that really doesn’t matter. We need to keep our eyes on the millions of people, the directions of entire nations. For a lot of people, looking at numbers is boring; but there are people behind those numbers, and numbers are what tell us what’s really going on in the world.

For example: Trump really does seem to have brought bigotry out in the open. Hate crimes in the US increased for the third year in a row last year.

Then there are his direct policy actions which are human rights violations: The number of children detained at the border has skyrocketed to almost 13,000.

On the other hand, the economy is doing quite well: Unemployment stands at about 4%, and median income is increasing and poverty is decreasing.
Global extreme poverty continues its preciptious decline, but global climate change is getting worse, and already past the point where some serious consequences are going to be unavoidable.

Some indicators are more ambiguous: Corporate profits are near their all-time high, even in inflation-adjusted terms. That could be a sign of an overall good economy—but it also clearly has something to do with redistribution of income toward the wealthy.

Of course, all of those things were true yesterday, and will be true tomorrow. They were true last week, and will be true next week. They don’t lend themselves to a rapid-fire news cycle.

But maybe that means we don’t need a rapid-fire news cycle? Maybe that’s not the best way to understand what’s going on in the world?
