This is something that cannot and should not be avoided though ... I remember reading this article in GQ magazine, many many moons ago, about fast twitch fibers being found more readily in people of West African Descent which is what makes them better sprinters (this is why your 100m, 200m races are dominated by people from America, West Africa and the Carribbeans) ... naturally I started to discuss this with a African American Studies Professor I was friends with at the time, and the response wasn't that the research was incorrect, but that it shouldn't be talked about because white supremacists, or other racists would seize upon it to make an argument that since athleticism could be so advantaged by race then intelligence could too.

It makes me sad that America's racial history makes things like this way more fraught with all sorts of dangers than it needs to be, but eventually we do have to do these kinds of research and find out how these things are related to our ancestors ... I for one, think we'll find that skin color has vanishingly little to do with these sorts of things ... I mean, in the matter of fast twitch muscles fiber, it turns out that not all black people have that advantage, only a small group of people from West africa

People will always try to describe things according to race in this country, but I think that as long as we're reasonably careful/responsible with the way we carry out the inquiry, it will benefit us in the long run.

FWIW, I'm white and Jewish, and I have a TT (ie, the opposite of this "intelligence gene").

Well even they do not look for co-relations we all know that Jewish and Chinese are the most intelligent ones. I read a recent study that showed most of the successful entrepreneurs are from Israel or China.
