Goodbye, IQ Tests: Brain Imaging Predicts Intelligence Levels
An anonymous reader writes "Research from Washington University in St. Louis has identified variations in brain scans that they believe identify portions of the brain that are responsible for intelligence (abstract). As suspected (and as explained by cartoons) brain size does play a small role; they said that brain size accounts for 6.7 percent of variance in intelligence. Recent research has placed the brain's prefrontal cortex, a region just behind the forehead, as providing for 5 percent of the variation in intelligence between people. The research from Washington University targets the left prefrontal cortex, and the strength of neural connections that it has to the rest of the brain. They think these differences account for 10 percent of differences in intelligence among people. The study is the first to connect those differences to intelligence in people."
Unless the MRI can show the brain as a series of miniature illustrations, these guys are about 121 years late to the game. But maybe that's just my approbativeness showing...
When you have nothing left to burn you must set yourself on fire
yeah, but now we could quantify how much intelligence a person is wasting.
I still prefer my method of estimating other people's IQ by correcting their spelling errors.

I assume you haven't heard the adage that goes "A fool learns from his mistakes. A wise man learns from the fool's mistake"
In other words, when there are no fools around the wise man doesn't learn anything at all. :-)
The Tao of math: The numbers you can count are not the real numbers.
If you have higher intelligence you get more experience points for completing the same quest or killing the same amount of creatures.
