Fidelity of married men depends on their IQ

According to some researchers, men subconsciously choose monogamous relationships, considering them as the safest option for relationships.

English scientists found that fidelity in marriage on the part of a man is directly proportional to the level of his intellectual development. In other words, the smarter the spouse, the less likely they are to cheat.

This is explained, first of all, by choosing monogamy in family life, men get rid of possible stress with the search, and then secret meetings with a partner, which as a result makes his reproductive system healthy.

Earlier, German scientists found that men are faithful to their wives, thanks to the hormone oxytocin, under the influence of which they avoid even the most beautiful women.
