Full quote

In both sexes, the European brains show an outbending of the hemispheric
surface in the occipital and frontal poles and of the
whole dorsal aspect of the hemispheres, whereas the
Japanese brains show an outbending in the interposed
regions. That means that the Japanese brains are
shorter, but wider than the European brains

Any neuro people care to weigh in on the effective difference this causes in the two's intellectual abilities?

Wider brain means stronger ability to process complex patterns like advanced math. Large frontal lobe gives more creativity and ingenuity.

Didn't look to closely, but Caucasian it seems have higher word fluency, word generation, so creativity.

Pretty much the stereo types.

Japanese it appears have adaptions to their language

Also the Japanese anime area... Okay that bit might be made up.

I don't think you can rationally learn anything from brain geometry, rather you take what you observe from performance testing and map that on to brain geometry to learn something about brain function.

For example, having more interstitial neurons (the ones connecting different parts of the brain) would suggest more creativity. But I don't think we see that with the Japs.

So it suggests that the assumptions about creativity may be wrong and instead creativity may come from a more logic based approach. It could be that a bigger frontal lobe leads to more creativity.

Creativity is abstract reasoning

Does this have implications for intelligence?
