There's a huge positive chunk of hypocrisy that we're missing there - hypocrisy allows us to have ideals higher than we can (and do) attain in our actions. It can have a tremendously aspirational effect. The phrase "all men are created equal" was written by rich, white slaveowners. Eliezer feels that if hypocrisy had been banned, they would have written the same phrase, and set all their slaves free. I fear that if hypocrisy had been banned, they would have kept their slaves and instead written "all rich, white men are created equal". And future progress would have been ruled out.
Ah, now there's a powerful argument.
But at the same time, if hypocrisy had not decreased, we would still have rich white slaveowners.
It should be assumed by default that when I talk about the benefits of overcoming bias, I am talking about the sort of human being who comes into existence when they set out to overcome their own biases by acts of mental will and training. Not, necessarily, the sort of entity that you get if you do neurosurgery on a human; nor the sort of entity that would have evolved if deception and self-deception had not been part of the ancestral environment.
The sort of human being who makes a continual effort to overcome hypocrisy, and who manages to do so, will probably set the slaves free.
(Claiming that "ideal Bayesians" would not have sponsored an Inquisition obscures this point, since it launches too great a counterfactual; this was probably a mistake of writing, if not of fact.)
George Orwell saw the descent of the civilized world into totalitarianism, the conversion or corruption of one country after another; the boot stamping on a human face, forever, and remember that it is forever. You were born too late to remember a time when the rise of totalitarianism seemed unstoppable, when one country after another fell to secret police and the thunderous knock at midnight, while the professors of free universities hailed the Soviet Union’s purges as progress. It feels as alien to you as fiction; it is hard for you to take seriously. Because, in your branch of time, the Berlin Wall fell. And if Orwell’s name is not carved into one of those stones, it should be.
Orwell saw the destiny of the human species, and he put forth a convulsive effort to wrench it off its path. Orwell’s weapon was clear writing. Orwell knew that muddled language is muddled thinking; he knew that human evil and muddled thinking intertwine like conjugate strands of DNA:1
Orwell was clear on the goal of his clarity:
To make our stupidity obvious, even to ourselves—this is the heart of Overcoming Bias.
Evil sneaks, hidden, through the unlit shadows of the mind. We look back with the clarity of history, and weep to remember the planned famines of Stalin and Mao, which killed tens of millions. We call this evil, because it was done by deliberate human intent to inflict pain and death upon innocent human beings. We call this evil, because of the revulsion that we feel against it, looking back with the clarity of history. For perpetrators of evil to avoid its natural opposition, the revulsion must remain latent. Clarity must be avoided at any cost. Even as humans of clear sight tend to oppose the evil that they see; so too does human evil, wherever it exists, set out to muddle thinking.
1984 sets this forth starkly: Orwell’s ultimate villains are cutters and airbrushers of photographs (based on historical cutting and airbrushing in the Soviet Union). At the peak of all darkness in the Ministry of Love, O’Brien tortures Winston to admit that two plus two equals five:2
I am continually aghast at apparently intelligent folks—such as Robin Hanson’s colleague Tyler Cowen—who don’t think that overcoming bias is important.3 This is your mind we’re talking about. Your human intelligence. It separates you from an orangutan. It built this world. You don’t think how the mind works is important? You don’t think the mind’s systematic malfunctions are important? Do you think the Inquisition would have tortured witches, if all were ideal Bayesians?
Tyler Cowen apparently feels that overcoming bias is just as biased as bias: “I view Robin’s blog as exemplifying bias, and indeed showing that bias can be very useful.” I hope this is only the result of thinking too abstractly while trying to sound clever. Does Tyler seriously think that scope insensitivity to the value of human life is on the same level with trying to create plans that will really save as many lives as possible?
Orwell was forced to fight a similar attitude—that to admit to any distinction is youthful naiveté:
Maybe overcoming bias doesn’t look quite exciting enough, if it’s framed as a struggle against mere accidental mistakes. Maybe it’s harder to get excited if there isn’t some clear evil to oppose. So let us be absolutely clear that where there is human evil in the world, where there is cruelty and torture and deliberate murder, there are biases enshrouding it. Where people of clear sight oppose these biases, the concealed evil fights back. The truth does have enemies. If Overcoming Bias were a newsletter in the old Soviet Union, every poster and commenter of Overcoming Bias would have been shipped off to labor camps.
In all human history, every great leap forward has been driven by a new clarity of thought. Except for a few natural catastrophes, every great woe has been driven by a stupidity. Our last enemy is ourselves; and this is a war, and we are soldiers.
