<artificially delaying maturity might result in higher intelligence> I don't think intelligence is affected. Just the ability to learn new tricks. Intelligence in adults of age 25 is, I gather, pretty much equal for males and females, but I guess I should ask Google. It's the learning new tricks part which is seized up at puberty. Learning new languages with new sounds is really really hard for people aged 25, but really, really easy for people aged 3. Maths is a language. Learning it after puberty is really, really hard. The grounding is needed before brain growth is finished. Smart people can do a good job of it when older, but they too do much better if started younger. Good old Google: < While there are essentially no disparities in general intelligence between the sexes, a UC Irvine study has found significant differences in brain areas where males and females manifest their intelligence. The study shows women having more white matter and men more gray matter related to intellectual skill, revealing that no single neuroanatomical structure determines general intelligence and that different types of brain designs are capable of producing equivalent intellectual performance. “These findings suggest that human evolution has created two different types of brains designed for equally intelligent behavior,” said Richard Haier, professor of psychology in the Department of Pediatrics and longtime human intelligence researcher, who led the study with colleagues at UCI and the University of New Mexico. “In addition, by pinpointing these gender-based intelligence areas, the study has the potential to aid research on dementia and other cognitive-impairment diseases in the brain.” Study results appear on the online version of NeuroImage. In general, men have approximately 6.5 times the amount of gray matter related to general intelligence than women, and women have nearly 10 times the amount of white matter related to intelligence than men. Gray matter represents information processing centers in the brain, and white matter represents the networking of – or connections between – these processing centers. This, according to Rex Jung, a UNM neuropsychologist and co-author of the study, may help to explain why men tend to excel in tasks requiring more local processing (like mathematics), while women tend to excel at integrating and assimilating information from distributed gray-matter regions in the brain, such as required for language facility. These two very different neurological pathways and activity centers, however, result in equivalent overall performance on broad measures of cognitive ability, such as those found on intelligence tests. > today.uci.edu Those are seriously weird differences. Women's brains being fully grown 3 years sooner must mean quite a lot in that grey/white difference. Mqurice
