You think sexual selection theory isn't a good explanation of behavioral sex differences?

It's a good explanation for non-humans. But explaining differences in human behaviour via genes quickly runs counter to human universality.

How is this distinguishable from blank slate hypotheses

In the same way as with actual slates. Saying their present content need not depend on previous content is not the same as saying they were initially blank, or initially identical.

Pinker was right to say the Blank Slate is wrong, but so is the Immutable Slate, which claims we cannot change our inborn dispositions.

The ratio of genetic determination vs susceptibility to environmental adaptation is probably variable and entirely genetically determined.

That’s true for most aspects of our bodies (e.g. muscle mass & skin tone), but genes don’t determine the scope of human thought - except by making it universal.

What makes you so sure that this has to be true? There are probably conditions under which a degree of innately enforced groupthink would have adaptive benefits for the group, and I don't think that it is impossible to encode tendencies for that genetically.

Suppose that’s true. What happens when somebody, a mutant perhaps, points out the groupthink about an idea? Presumably human brains can represent variants of that idea. What, other than an irrational *culture*, could prevent them from adopting such a variant?

Like differences in height, having different kinds of minds is a normal part of population diversity. However, history is full of purges of intellectuals, infidels (and their offspring) etc. especially when rulers wanted to breed more collectivist or docile societies.

It seems that most people have to difficulty to accept irrational beliefs when presented by high ranking ingroup members (especially in childhood and adolescence) and to stick to them, even when presented with clear evidence to the contrary. That has obvious adaptive value.

You two seem to both agree on the difference between hard changes and impossible changes and just seem to disagree because you're stressing different things

I think that homo sapiens is not so successful because we are more intelligent than other hominids, but because we sacrificed universality for programmability. It happened via mutations that bias the mind towards authoritarian groupthink ("normies") and against rationality.
