I guess being raised in a white environment allows them to more attuned with their white side

That was my theory as well.

American mulattoes are a tricky category. American blacks are about 25% white, to begin with. Mostly British. So when they mate with a white person, their offspring is about 62.5% white.

I am aware of that, which would explain the difference if the mulattoes had an IQ the mean between the blacks and whites used in the same study. However, the mulattoes have an average IQ higher than the mean between those other races.

Well, phenotypical expression is generally a polygenic affair. There's no guarantee that a mix within a white and black person would produce a child that has an average of their iqs. The resultant child could have an IQ higher or lower than the average.

I think there's a selection bias as well. Lightskins are privileged in the black community and due to their better aesthetics, its likely they'd be preferred for adoptions as well. Attractive orphans are much more likley to get adopted. I think these mulattoes might be as high as 70-75% white.
