Steve Hsu giving a talk @ Google on the topic, with myriad citations: [VIDEO] Four studies cited on this handy chart: [LINK] It's very well-established science that you could have easily googled, but downvoting unpopular research, pointing and shrieking "eugenics!" is a better argumentation technique, I suppose.

It's only bold because there is a large number of people (often state founded, often controlling at least the lower levels of education, often with major influence on media) who strongly feel otherwise -- with no numbers to back them up, of course. --- If you actually do want to get to the bottom of it, I can heartily recommend Ian Deary's "Intelligence: A Short Introduction" as a place to start. [LINK] (Who knows, if you dig around a bit you might even be able to find a PDF, perhaps at Emil Kirkegaard's website.) You can also choose to spend an hour on this talk by Stephen Hsu who does research on IQ and genetics: [VIDEO] You can read some of Plomin's stuff -- he is very much into genetics: [LINK] There's a paper I can't find at the moment that looks at almost 4000 non-related people, give them an IQ test each + scan their DNA for typical SNPs with a DNA chip. That gives us almost 8,000,000 pairs where we know how similar their IQ score and DNA was. That gives us almost 8,000,000 points we can plot into a 2D coordinate system (and we can of course also throw statistics at them). It turns out that there is a clear correlation between measured IQ and measured SNPs (i.e., the point cloud is denser along a line). In other words, there is a statistical relation between DNA and IQ. This is a result that is extremely hard to explain away if one believes in nurture, SES, microaggressions, racism, ESL difficulties, etc. Since it is such a rhetorically important paper, I hope somebody

I am growing more disturbed in recent years by how true this statement is in our current society. While not all behavior is hereditary, genetics plays a massive role. I wish it were not taboo to talk about this more openly. While I have found few, at least there are some people attempting to give this subject more consideration: [LINK] [VIDEO]
