When you think about cheating, it ’s only natural to think of John Mayer or Alex Pettyfer-esque philandering. But did you know that women are just as guilty? In a study by scientists and psychologists from the University of Texas and California State University, heterosexual women in relationships are likely to seek out alternative mates in what they call a “mate-switching hypothesis”, which says that humans have evolved to keep testing their relationships and looking for better partners for the long haul.
The study takes into account the behaviour of past societies, stating that our female ancestors faced three kinds of scenarios that would prompt them to switch mates — a perceived decline in value of their current partner, an increase in their own value, and the presence of potential partners of higher value that weren’t around before. Perhaps you can also add to that, the ever-tempting gallery under the hashtag # ManCrush Mondays.
Another study by the University of Queensland put it down to hormones like vasopressin — it influences feelings of empathy, trust and affection, so it makes sense that it would have an effect on sexual behaviour. Whether or not the gene mutates is dependant on your parents, since you get one from each of them. However, beyond running a gamut of tests, it ’s not easy to find out if you carry this mutation. You know when he says “it ’s not my fault ”? Yeah.
