+Why _is_ the blank slate doctrine so compelling, that so many feel the need to protect it at all costs? 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. We could certainly imagine that none of the relevant selection pressures 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.
