Just for the record, saying intelligence is 80% hereditary isn't the same as saying that 80% of a person (or group's) intelligence is due to genetics.
It means that 80% of the *variation* in intelligence within a specific population - (usually white middle-class people, for heritability studies, as it happens) - is due to genetics. The other 20% due to environmental factors.
So, the difference between the dumbest and smartest person in a group is 60% - 80% due to genetic difference, 20% environmental difference ..but even then, people dispute this.
And if you think environment has little influence on individual cognitive development, just imagine a child raised in a cardboard box, or a kid raised by wolves. It's going to have a pretty big impact...
I'm not commenting on race relations, I don't really care. This is purely a comment on the statistic, that - the way it was presented seems pretty misleading to me.
So you're probably going to tell me to fuck off, because you seem like a bit of a dick!
Whites are just re-segregating themselves anyway.

But whatever, take it easy!
