To begin with, they quantified the sum and area of dark issue (infrequently called “thinking matter”) in 116 sections of the mind to discover which regions had the greatest sex contrasts. Next, the group scored these territories on each sweep as either falling into the “female-end” zone, the “male-end” zone, or some place in the center.
It worked out that perhaps 6 in each 100 of the brains they examined were reliably a solitary sex. Numerous others had an intricate interwoven pattern of manly and female highlights that fluctuated broadly from individual to individual.
To check their discoveries, the group utilized comparable techniques to break down more than 5,500 individuals’ identity characteristics and conduct. While a few exercises were more typical in ladies (counting scrapbooking, visiting on the telephone, and staying in contact with mother) and others in men, (for example, hitting the fairway, playing computer games, and betting), 98% of those contemplated didn’t fit an obvious sex profile.
