Dr. Cordelia Fine, with a Ph.D. in cognitive neuroscience from University College London, notes in her summary of many gender studies in her book, Delusions of Gender, about gender and the brain a) several studies have found no difference in hemispheric size in neonates; b) the allegedly bigger female corpus (callosum) is in dispute and c) size vs function has not been proven: as Dr. Fine notes, “getting from brain to behavior has proved a challenge.” There may be biological difference in brain, but what do they show us about our thinking?
