Men with higher IQ's are less likely to cheat on their wives and hence, more faithful, says a new study.

The intelligent men put greater values on monogamy and sexual exclusivity than the less intelligent people. Evolution is the causative factor for this circumstance. The analysis of social trends also found that women do not follow the same trend.

The studies about this topic also showed that the correlation between intelligence and monogamy in men has its origins in the evolutionary development.

The study is done by Dr Satoshi Kanazawa, from London School of Economics and Political Science. This is published in the journal, Social Psychology Quarterly.
