Scientists from Boston University found that blondes have the highest intelligence scores among women. Research results It was published On the ResearchGate portal.
Almost three thousand women participated in the experiment. Those with blonde hair had the highest average IQ score of 103.2. Blondes also had the smallest standard deviation (12.8), indicating that intellectual abilities were more evenly distributed within this group.
Brown-haired women, who made up the majority (73%) of the study participants, also performed well, with an average IQ of 102.7. However, their groups had a wide range of values (standard deviation 13.8).
Representatives with red and black hair had lower scores: the average IQ of red-haired women was 101.2 points (3.8% of the entire sample), while black-haired women had 100.5 points (2.5%).
Within the scope of the research, the male part of the sample was also examined. The leaders here were brown-haired men with an average IQ of 105.4 points. Blondes took second place with 104.3 points. Men with red and black hair showed more modest results, with 100.6 and 98.7 points, respectively.
Researchers emphasize that the discovered relationship between hair color and intelligence is most likely due to social and economic factors rather than biological predisposition. These findings challenge stereotypes about the connection between people’s mental abilities and different hair shades.
