According to a recent study of the brains of identical and fraternal twins, differences in the amount of gray matter in the frontal lobes are not only genetically influenced but are significantly correlated with differences in intelligence.

What if there are not only two nostrils, two eyes, two lobes, and so forth, but two psyches as well, and they are separately equipped? They go through life like Siamese twins inside one person.... They can be just a little different, like identical twins, or they can be vastly different, like good and evil.
Norman Mailer
If you analyze a host of real world outcomes using adoption studies, fraternal v. identical twin studies, twins-raised-apart studies, the history of early childhood intervention research, naturally-occurring experiments, differences between societies, changes over history, and so forth, you tend to come up with nature and nurture as being about equally important: maybe fifty-fifty. The glass is roughly half-full and half-empty.
Steve Sailer
We all know- or at least we are told continually- that we are a divided people. And we know there's a degree of truth in it. We have too often allowed our differences to prevail among us. We have too often allowed ambitious men to play off those differences for political gain. We have too often retreated behind our differences when no one really tried to lead us beyond them. But all our differences hardly measure up to the values we all hold in common... I am running for the Senate because... I want to make the system work again, and I am convinced that is what all Americans really want.
Joseph (Joe) Biden
It is ironic that a movement that made its reputation championing the irrelevance of biological differences when those differences were to most women's disadvantage immediately returned to biological determinism when those differences were to the most women’s advantage.
Warren Farrell
The evolvers are people who cause things to change. The maintainers of the status quo do everything to keep things from changing. And, there I see differences of perception. Differences in vision. Differences in interpretation, and differences in temperament, in personality. The number of evolvers are much fewer than the maintainers of the status quo. And amongst the evolvers, there are some who are initiators, some who go along with what other people recognize to be new or different.
