Men with higher intelligence may be more likely to stay faithful and committed in their romantic relationships, according to a new scientific study. The research, which analysed over 200 men, points to a clear link between cognitive abilities and healthier partnership behaviours.
The Science Behind Smarter Relationships
The study was conducted by researchers at Oakland University and published in the journal Personality and Individual Differences. The team, led by data analyst and social scientist Gavin Vance, examined 202 heterosexual men who had each been in a relationship for at least six months.
Participants were tested on their ability to solve puzzles and unpick patterns in sequences of numbers and letters. The findings, released on Tuesday 2 December 2025, revealed that men who scored higher on these specific intelligence tests often reported a more stable and positive romantic life.
Key Traits of Intelligent Partners
The analysis showed these men expressed greater commitment to their partners and were less likely to display jealousy or insult their significant others. They also tended to avoid using controlling "mate-retention" tactics, which are behaviours designed to make it difficult for a partner to leave the relationship.
Furthermore, the study indicated that these individuals were less tempted by risky behaviour outside their relationship. They also reported fewer issues with erectile dysfunction and exhibited fewer psychopathic tendencies.
Understanding the Limitations and Future Research
The authors have been careful not to overstate their conclusions. The study did not measure acts of infidelity directly but instead suggests that men with this particular psychological profile, shaped by their intelligence, are more compatible with remaining faithful.
They stress that the findings are modest and cannot definitively prove cause and effect, as the results rely on the men's own reports of their behaviour. However, the team believes the results warrant further investigation and follow-up analysis.
This research aligns with a similar study from the University of Sydney published earlier in the year, which found that couples where the male partner has high emotional intelligence experience greater satisfaction and trust.
In the modern landscape of online dating, where appearances often take precedence, this new insight suggests that intelligence and problem-solving abilities could be a significant, yet overlooked, foundation for a happy and healthy long-term relationship.
