A new study by evolutionary psychologist Dr. Satoshi Kanazawa of the London School of Economics proposes that women are more comfortable with their sexual orientation than men due to evolutionary pressures. Dr. Kanazawa’s research, published in Biological Reviews, suggests that women’s experiences with “polygamous marriages” throughout history have led to greater sexual fluidity.
Defining Sexual Orientation: A Multifaceted Approach
The study challenges the traditional view of fixed sexual orientations, arguing that women’s attraction is more influenced by factors like their partner, reproductive status, and circumstances. Dr. Kanazawa emphasizes that brain and genital responses are the most accurate indicators of sexual orientation, highlighting three key aspects: non-exclusivity, fluidity over time, and variability across individuals.
Data-Driven Insights from the National Longitudinal Study of Adolescent Health
The research analyzed data from the National Longitudinal Study of Adolescent Health (Add Health), a 10-year longitudinal study of American adolescents. The study measured sexual orientation through self-identification and assessed changes in sexual attraction over time.
Key Findings: Women’s Sexual Fluidity and Reproductive Success
The findings revealed that women exhibited greater sexual fluidity compared to men. Additionally, the study found a correlation between sexual fluidity and reproductive success in women, with more sexually fluid women having more children. Conversely, women who married and had children early demonstrated less sexual fluidity.
Evolutionary Interpretation: Sexual Fluidity as a Reproductive Advantage
Dr. Kanazawa posits that women’s sexual fluidity evolved as an adaptive trait, facilitating the formation of strong social bonds and alliances, which in turn increased reproductive success.
