CNN Reports: The Search for Genius

From CNN.com: Brainteaser: Scientists Dissect the Mystery of Genius

""If I showed you two brains side by side, one with an IQ of 150, one with an IQ of 75, I can't tell the difference," says Jay Giedd of the National Institute of Mental Health, one of the most experienced researchers in the field.

But Jung and his colleague Dr. Richard Haier of the University of California, Irvine, claim they are on the verge of refining imaging techniques to a point that would make traditional intelligence tests obsolete."

They're suggesting that the amount of grey matter correlates with intelligence, so the ability to measure grey matter will do away with the need for intelligence tests. I think this is an unnecessarily limited view. Since women have much more white matter than men (men have more grey than white), I suppose it figures male scientists would think measuring only grey matter was reasonable. ;-)

Anyway, "Genius: Quest for Extreme Brain Power," hosted by Dr. Sanjay Gupta, airs at 10 p.m. ET Sunday.
