-This kind of [claim to be non-disprovable](https://www.lesswrong.com/posts/fAuWLS7RKWD2npBFR/religion-s-claim-to-be-non-disprovable) seems like the kind of thing you would only invent if you _were_ subconsciously worried about _X_ being threatened by new discoveries, and wanted to protect your ability to backtrack and re-gerrymander your definition of _X_ to protect your existing beliefs.

+If being an oblivious science nerd isn't an option, half-measures won't suffice. I think we can do better by going meta and analyzing the _functions_ being served by the constraints on our discourse and seeking out clever self-aware strategies for satisfying those functions _without_ [lying about everything](/2017/Jan/im-sick-of-being-lied-to/). We mustn't fear opening the dread meta-door in front of whether there actually _are_ dread doors that we must fear opening.

+Why _is_ the blank slate doctrine so compelling, that so many feel the need to protect it at all costs? (As I once felt the need.) It's not ... if you've read this far, I assume you _will_ forgive me—it's not _scientifically_ compelling. If you were studying humans the way an alien superintelligence would, trying to _get the right answer for the right reasons_, you wouldn't put a whole lot of prior probability on the hypothesis "Both sexes and all ancestry-groupings of humans have the same distribution of psychological predispositions; any observed differences in behavior are solely attributable to differences in their environments." _Why_ would that be true? We _know_ that sexual dimorphism exists. We _know_ that reproductively isolated populations evolve different traits to adapt to their environments, like [those birds with differently-shaped beaks that Darwin saw on his boat trip](https://en.wikipedia.org/wiki/Darwin%27s_finches). We could certainly imagine that none of the relevant selection pressures on humans happened to touch the brain—but why? Wouldn't that be kind of a weird coincidence?

+If the blank slate doctrine isn't _scientifically_ compelling—it's not something you would invent while trying to build shared maps that reflect the territory—then its appeal must have something to do with some function it plays in _conflicts_ over the shared map, where no one trusts each other to be doing Actual Social Science rather than lying to fuck everyone else over.

+And that's where the blank slate doctrine absolutely _shines_—it's the [Schelling point](/2019/Oct/self-identity-is-a-schelling-point/) for preventing group conflicts! If you admit that there could differences between groups, you open up the questions of in what exact traits and of what exact magnitude, which people have an incentive to lie about to divert resources and power to their group by [establishing unfair conventions and then misrepresenting those contingent bargaining equilibria](/2020/Jan/book-review-the-origins-of-unfairness/) as some "inevitable" natural order.
