Men who are smart enough to be faithful in love are also smarter in general according to a new study. Recent research by Satoshi Kanazawa indicates that there is a link between intelligence and monogamous men. It has to do with human evolution.
There is sufficient evidence in nature to show that the beginnings of human relationships were primarily polygamous in nature. The proof begins with the slightly larger body size of the male sex, as compared to women. Kanazawa also believes prehistoric women were promiscuous and in polygamous (one man, several female sexual partners) relationships, just by looking at how man has developed in comparison to our closest relatives, the primates.
This trait is believed to be useful in fighting off the competition for available women. The gorilla is an extreme example of this type of society, being a great deal larger than the female. The Gorillas testes are however notably smaller than the Bonobo and Chimpanzee, theoretically because their harems are more exclusive to him, leaving less necessity for large dose of sperm to compete with other males.Additionally, Kanazawa points out that the male member may have evolved into a mushroom shape to overcome female promiscuous behavior. This appendage could theoretically extract or scoop old semen from a woman’s cervix, before depositing his own new seed.
Intelligence and Monogamy
The basis of Kanazawa’s thesis is that men may have needed polygamous societies in the past to survive, but in modern society, the intelligent man has the more highly developed brain to leave biology behind in exchange for fostering secure, intimate, trusting relationships. The dumber guy worries less about cheating, more easily falling victim to his baser instincts.
The basis of this conclusion falls under a large U.S. survey looking at IQ and attitudes of men towards monogamous vs. polygamous relationships. The evidence suggests that the more intelligent the man, the more he valued the idea of a monogamous relationship. Of the women surveyed, they showed much less predictability of preference to monogamy based on their intelligence.
As far as female evolutionary theory goes, women have had to adapt very little considering they are still faithful to one mate regardless of a monogamous or polygamous relationship. Therefore, women would have less biological reason to value sexual exclusivity. Indeed, recent studies have found that women experience less guilt while cheating.
Could it be that more intelligent men are simply more adept at concealing infidelity? Perhaps it is the intelligent women who choose to be more honest and forthright. What about the highly intelligent men who have been accused of cheating, such as Eliot Spitzer and John F. Kennedy? Do positions of power put a spin on this theory? Where does this leave us?
What we do know is that love, romance, security, intimacy, and exclusivity are all needed to experience the 7 stages of relationships, which is one of the most beautiful experiences a person can have. If it takes intelligence to understand that, then so be it.
