Evidence for a link between genetics and intelligence. This should not be terribly surprising… genetics is responsible for a *lot* about a person, from physicality to personality. But for some reason, some people get damn upset when you start discussing the idea that there is a genetic basis for intelligence. Sure, environment – from the quality of your nutrition to the quality of your parents to the quality of you schooling – plays a role. Epigenetics plays a role. But why *wouldn’t* genetics play a role? The reason why humans are smarter than chimps isn’t because we have better school lunch programs.

One obvious notion to be drawn from the recognition of a genetic basis for intelligence is that it should be possible to breed for it… or against it. And boy howdy do a whole lot of people not want to consider *that* possibility.

Study also concludes that the “smart genes” studied also have a role in autism.
