Robin Hanson proposed stores where banned products could be sold. There are a number of excellent arguments for such a policy—an inherent right of individual liberty, the career incentive of bureaucrats to prohibit everything, legislators being just as biased as individuals. But even so (I replied), some poor, honest, not overwhelmingly educated mother of five children is going to go into these stores and buy a “Dr. Snakeoil’s Sulfuric Acid Drink” for her arthritis and die, leaving her orphans to weep on national television.
I was just making a simple factual observation. Why did some people think it was an argument in favor of regulation?
On questions of simple fact (for example, whether Earthly life arose by natural selection) there’s a legitimate expectation that the argument should be a one-sided battle; the facts themselves are either one way or another, and the so-called “balance of evidence” should reflect this. Indeed, under the Bayesian definition of evidence, “strong evidence” is just that sort of evidence which we only expect to find on one side of an argument.
But there is no reason for complex actions with many consequences to exhibit this onesidedness property. Why do people seem to want their policy debates to be one-sided?
Politics is the mind-killer. Arguments are soldiers. Once you know which side you’re on, you must support all arguments of that side, and attack all arguments that appear to favor the enemy side; otherwise it’s like stabbing your soldiers in the back. If you abide within that pattern, policy debates will also appear one-sided to you—the costs and drawbacks of your favored policy are enemy soldiers, to be attacked by any means necessary.
One should also be aware of a related failure pattern, thinking that the course of Deep Wisdom is to compromise with perfect evenness between whichever two policy positions receive the most airtime. A policy may legitimately have lopsided costs or benefits. If policy questions were not tilted one way or the other, we would be unable to make decisions about them. But there is also a human tendency to deny all costs of a favored policy, or deny all benefits of a disfavored policy; and people will therefore tend to think policy tradeoffs are tilted much further than they actually are.
If you allow shops that sell otherwise banned products, some poor, honest, poorly educated mother of five kids is going to buy something that kills her. This is a prediction about a factual consequence, and as a factual question it appears rather straightforward—a sane person should readily confess this to be true regardless of which stance they take on the policy issue. You may also think that making things illegal just makes them more expensive, that regulators will abuse their power, or that her individual freedom trumps your desire to meddle with her life. But, as a matter of simple fact, she’s still going to die.
We live in an unfair universe. Like all primates, humans have strong negative reactions to perceived unfairness; thus we find this fact stressful. There are two popular methods of dealing with the resulting cognitive dissonance. First, one may change one’s view of the facts—deny that the unfair events took place, or edit the history to make it appear fair. (This is mediated by the affect heuristic and the just-world fallacy.) Second, one may change one’s morality—deny that the events are unfair.
Some libertarians might say that if you go into a “banned products shop,” passing clear warning labels that say Things In This Store May Kill You, and buy something that kills you, then it’s your own fault and you deserve it. If that were a moral truth, there would be no downside to having shops that sell banned products. It wouldn’t just be a net benefit, it would be a one-sided tradeoff with no drawbacks.
Others argue that regulators can be trained to choose rationally and in harmony with consumer interests; if those were the facts of the matter then (in their moral view) there would be no downside to regulation.
Like it or not, there’s a birth lottery for intelligence—though this is one of the cases where the universe’s unfairness is so extreme that many people choose to deny the facts. The experimental evidence for a purely genetic component of 0.6–0.8 is overwhelming, but even if this were to be denied, you don’t choose your parental upbringing or your early schools either.
I was raised to believe that denying reality is a moral wrong. If I were to engage in wishful optimism about how Sulfuric Acid Drink was likely to benefit me, I would be doing something that I was warned against and raised to regard as unacceptable. Some people are born into environments—we won’t discuss their genes, because that part is too unfair—where the local witch doctor tells them that it is right to have faith and wrong to be skeptical. In all goodwill, they follow this advice and die. Unlike you, they weren’t raised to believe that people are responsible for their individual choices to follow society’s lead. Do you really think you’re so smart that you would have been a proper scientific skeptic even if you’d been born in 500 ce? Yes, there is a birth lottery, no matter what you believe about genes.
Saying “People who buy dangerous products deserve to get hurt!” is not tough-minded. It is a way of refusing to live in an unfair universe. Real tough-mindedness is saying, “Yes, sulfuric acid is a horrible painful death, and no, that mother of five children didn’t deserve it, but we’re going to keep the shops open anyway because we did this cost-benefit calculation.” Can you imagine a politician saying that? Neither can I. But insofar as economists have the power to influence policy, it might help if they could think it privately—maybe even say it in journal articles, suitably dressed up in polysyllabismic obfuscationalization so the media can’t quote it.
I don’t think that when someone makes a stupid choice and dies, this is a cause for celebration. I count it as a tragedy. It is not always helping people, to save them from the consequences of their own actions; but I draw a moral line at capital punishment. If you’re dead, you can’t learn from your mistakes.
Unfortunately the universe doesn’t agree with me. We’ll see which one of us is still standing when this is over.
