Do you think it's the identical twin / fraternal twin studies? The comparative population studies? The adoption studies? Which do you think separates out the influence of institutionalized bias that is epigenetic / environmental?

@DrDebraSoh @jordanbpeterson @RichardBSpencer @KirkegaardEmil Any of you care to comment?

Maybe you don't accept the premise that bias is heritable? If not, what definition of heritability are you using?

I mean, one very obvious way in your question is just including skin tone along with IQ etc. to predict income. When that is done, skin tone has just about no validity. I am currently working on a big paper where I did these kinds of regressions for 5 large public datasets.

So, if IQ differences had some causal influence from bias against skin tone (attitudes of educators, self-identification, verbal abuses and other stressors), wouldn’t that day set hide that info behind the racial IQ gap?

I mean, that’s kind of the reason I’m asking too. Your response has all of these assumptions in it - about which kinds of biases can affect development in this way, what directions those affectors have moved.. What is the actual signal you use to make those conclusions?

Because clearly, when we measure bias, we find a lot of it in our current society. Throughout career advancement, penalization, and basic emotional response, we know many different biases exists. How does one extract this from the heritability signal, since it is heritable.
