A new study challenges the stereotype that muscular men are less intelligent, finding that those with masculine body shapes tend to be smarter and less promiscuous. Researchers from Oakland University discovered that young men with higher intelligence often exhibit physical traits such as a strong hand grip and a greater shoulder-to-hip ratio, commonly known as a V-shaped torso.
Key Findings
The study, published in the journal Evolutionary Psychological Science, involved 41 men aged 18 to 34. Participants underwent intelligence tests, provided sexual history questionnaires for a promiscuity score, and had their grip strength, BMI, height, and body shape measured. Results showed significant positive correlations between intelligence, grip strength, and shoulder-to-hip ratio, while a negative correlation emerged between intelligence and promiscuous behaviors.
Challenging Stereotypes
Lead author Tara DeLecce stated, 'Our findings more align with the idea that, at least among men, intelligence is related to physical health and/or good genes but is inversely related to promiscuous sexual behaviour.' This suggests that highly intelligent men may be more successful in monogamous, long-term relationships rather than casual encounters. The researchers propose that evolving towards sexual exclusivity may require higher intelligence to navigate successfully.
Body Shape and Attractiveness
The V-shaped body, exemplified by celebrities like Dwayne 'The Rock' Johnson and Arnold Schwarzenegger, is associated with masculinity and physical health. In contrast, a pear-shaped body with narrower shoulders and broader hips, seen in figures like Leonardo DiCaprio and Michael McIntyre, is less linked to these traits. Interestingly, previous research indicates that women often prefer men with more feminine faces, and a separate study found that meat consumption is linked to perceptions of masculinity.
Implications
The study provides a nuanced view of how physical and cognitive traits relate to overall fitness. It suggests that intelligence may play a role in mating success within monogamous contexts, challenging the notion that brawn and brains are mutually exclusive. Further research is needed to explore these dynamics across larger and more diverse populations.
