This has come up a bunch on HN and I don't want to rehash dozens of earlier comments, but the search bar will give you plenty of cites.
I'm not sure what you mean by "hereditarian" given that even the genetic studies obviously point to significant heritability.
This is always a funny conversation because on the one side you have people saying "intelligence is both heritable and correlated with nearly every outcome we care about."
On the other hand you have people saying "nuh uh! It's only... medium-high heritability and medium-high correlation with other positive outcomes," as if it makes any material difference to any downstream question.
Again, the search bar will avail, but the answers you're giving here are very early-90s.
Why don't you just share what your estimate is?
Is it zero?
It's totally OK if we're just not going to persuade each other or develop any productive ideas in this thread! I've said all I originally wanted to say.
