I enjoyed reading a review of Sick Societies. Seems like it's difficult to find the right balance between "primitive cultures are stupid" and "everything in primitive cultures is full of deep wisdom that we modern people are unable to understand".
As usual, the public opinion moves as a pendulum; on the social level it goes from "we are 100% correct about everything, there is nothing to learn from others" to "everything would be better if we replaced our ways by the wisdom of others".
In the rationalist community, I think we started at the position of thinking about everything explicitly, and we keep getting "post-rationalist" reminders of Chesterton's fences, illegible wisdom hidden in traditions (especially Buddhism), et cetera. Which is good, in moderate doses. But it is also good to admit that sometimes things that seem stupid... are actually stupid. Not every seemingly stupid behavior contains a hidden wisdom; sometimes people are stupid and/or stuck in horrible Nash equilibria.
As usual, the frustrating answer is "it depends". If we see something that doesn't make sense to us, it is good to try figuring out whether there is a good reason we missed. But this doesn't mean there always is a good reason. It doesn't even mean (as Chesterton would implore us) that we can find out why exactly some tribe started doing this many years ago. Maybe they simply made a mistake! Or they had a mad leader who was good at killing those who opposed him, but his policy proposals were disastrous. They were just as fallible as we are; possibly much more.
I don't have an exact definition, but approximately it is a behavior that is justified by false beliefs, and if only one person did it, we would laugh at them, and the person would only be hurting themselves... but if many people start doing it, and they add an extra rule that those who don't do the thing or even argue against doing the thing must be punished, they can create a Nash equilibrium where people doing the thing hurt themselves, but people who refuse to do the thing get hurt more by their neighbors. And where people, if they were allowed to thin... (read more)
