Infidelity in a woman occurs about half as often as in a man, but it is a more bewildering concept.

Although experts disagree on actual figures, most do concur that infidelity by man is far more prevalent than that by woman, generally by a two to one margin. Yet, far more Internet searches are performed on "infidelity and woman" than there are for the masculine counterpart. A closer look reveals why.

Women are not as bewildered by a man s adultery as men are bewildered by a female s. A big reason for this is cultural - society tells us that "Men can t help themselves". Indeed, in some cultures, male polygamy is not only acceptable but preferred. Female adultery, however, is not accepted in most cultures. Only about 10% of the different societies in the history of humanity have been matrilineal, and relatively few of those accepted women having multiple husbands as a social norm.

It is thus logical to expect more Internet searches on infidelity in woman. A man in Western society was always assured that as long as he was a good provider, he wouldn t have to worry about his wife straying. So when the woman does cheat, it s bewildering enough to send a man to the search engines looking for "infidelity woman".
