How does (intra-human) cultural variation in individualism/collectivism feed into this?
Those are finer-grained variations, and aren’t explained by sexual diploidy, since all humans are sexually diploid.
To the extent that such finer-grained variation is possible, it suggests that the constraint you’re positing isn’t actually that much of a constraint.
Maybe I’m still missing the point of the post.
