“There's no crime gene. There's no addiction gene. There's just like there's really no obesity gene. There's lots of genetic differences and so there's a there's a distribution.”

Genetic research has significantly altered how experts understand behavioral development, as traits like personality and psychopathology are roughly fifty percent heritable.

“all these traits are about 50 we say heritable that is where the differences are caused by inherited dna differences the other half is environmental but it's not due to these systematic family effects”

Denying the genetic basis for individual and group differences, including in intelligence, leads to a misunderstanding of social inequality and harmful political policies.

“Nevertheless, there are actually moral risks to denying IQ and its importance in everyday life because if you don't understand that this is a real phenomenon and that some people have more of it than others, then what you're going to end up saying is, "Look, there's a class of people who are just pr”
