Scientists Can Now Predict Intelligence From Brain Activity

Chelsea Leu in Wired: 

But now that neuroscientists have used maps of people’s brains to accurately predict intelligence, reality creeps ever so much closer to fiction.

By intelligence, in this case, the scientists mean abstract reasoning ability, which they inferred by mapping and analyzing the connections within people’s brains. But the study, published today in "Nature Neuroscience", is compelling because it gets at a fundamental and very uncomfortable truth: Some brains are better than others at certain things, simply because of the way they’re wired. And now, scientists are closer to being able to determine precisely which brains those are, and how they got that way.
