The Left has argued for years that there is no meaningful correlation between brain size and intelligence. Though science, and common sense, say otherwise, there has been an ongoing campaign to misinform and confuse the public in this matter.
Nobody claims that absolute brain size is a sign of greater intelligence; if this were the case, then elephants and whales would be far more intelligent than humans. Body size must be taken into consideration. Furthermore, nobody claims that there is a perfect correlation either; some people with large brains will be stupid, and some people with small brains will be geniuses. Nevertheless, there is a robust correlation, somewhere in the neighborhood of .4.
The reason the Left is so loath to admit this correlation is that it means that any discovery of average brain size differences between the races would present a challenge to their beliefs. Just as the rabbis of old built a fence around the Torah, reasoning that if Jews obeyed rabbinical injunctions, they would be less likely to transgress against actual Torah commandments, so too does the Left build fences around their faith. In this case, they both deny that there are brain size differences (taking body size into account) between the races and that such differences can be a smoking gun for actual I.Q. differences. Building these fences makes them feel safe and secure in their faith.
However, a recent Oregonian article (from 12/13/11, as of today not yet available online) does admit, indirectly, that brain size can be correlated with intelligence – at least among cabbies!
Street smarts help cabbies’ brains grow
London taxi drivers aren’t like the rest of us. Researchers have known for more than a decade that these elite cabbies – who train for years to master “the knowledge,” a mental map of 25,000 streets – have a larger than average rear hippocampus, a brain region linked to learning and navigation.
What scientists didn’t know was whether the drivers grew bigger hippocampi as they trained or whether they had big ones (and thus an innate navigation advantage) to begin with. So a team followed three groups: trainees who successfully acquired the Knowledge and became cabbies; trainees who failed to qualify; and a control group of non-taxi drivers; over four years, testing them and scanning their brains before, during and after training.
The team found that the brains of qualifying trainees were no different from those of nonqualifying trainees or non-taxi drivers before beginning training. But as the cabbies learned the Knowledge, their hippocampi grew, literally changing their minds…
The hippocampi of unsuccessful trainees stayed the same throughout, which could suggest that successful cabbies really do have an innate advantage: Their brains are more malleable than others’.
The mainstream media does have a lot of faith in the stupidity of the masses, that they are unable to put two and two together. I fear that they may be right. The masses need bigger brains.
