I'm just not sure if he's truly followed through with the implications of what he says

he?

Jordan Peterson. I'd expect Sargon fans to be aware of him

Jordan Peterson uses our natural biological urges as a lense through which to see why people don't mesh with acting in the PC way.

I'm not sure he advocates biologicalism just points out that trying to socially engineer people to act a different way than is natural is a bad idea.

Well, I believe he does hold that IQ is partially heritable

and that social hierarchies are based on principles, that those who embody those ideals reach the top, and those near the top are more likely to reproduce and survive

I'm connecting some of the dots though

surely some cultures cannot be developed or adopted by a group of people of just any IQ

and that personality surely affects ones values

openness, conscientiousness, extravertedness, agreeableness, neuroticism

You're interpretting IQ very interestingly here

IQ hasn't really changed for humans for the entirety of history

IQ is a proxy for G, general intelligence

Just the ability to maximise its use

are you sure about that?

Well of course it doesn't change a 100 IQ is fixed to the avrage

Completely, unless you want to go back to pre-human beings

how about pre-history? in our evolutionary development, surely our G factor increased from our ape-like ancestors

as soon as we became "human," we all stopped?

what of the difference in IQ after the divergence of the races?

different environments caused a divergence of development in human beings

it would be surprising if everyone's IQ ended up being the same through their long period of separated development

Oh there's probably divergence

different environments resulted in different challenges to survival and different optimal social orders

but not enough to matter

resulting in different cultures

IQ is best considered on an individual basis really

does anyone have data on racial iq diffrences over time?

I disagree. Groups behave a bit more deterministically based on IQ

over recent history, maybe

Well let me ask you a question

look up the Flynn effect

Is IQ all that matters to a society's direction and decisions?

nope

no, I think personality is a factor as well

as well as a host of other things, like the historical narrative and philosophy which may form the basis of those decisions

however those two not necessarily independent of those traits

Yeah so they are factors

But how big a factor?

well, for example, Asians have higher IQ than Caucasians, but they are likely more collectivist due to a personality difference
