There’s an excellent journal out there which collects the reults of improbable research. This particular story doesn’t belong there at all: it belongs in one about believable research. Another way of putting this might be that the result is blindingly obvious to anyone who knows anything at all about sex.

So, using various cleverly constructed experiements the researchers tried to work out whether being flirted with by those apparently available made men and women react differently. The answer was yes.

Men who were flirted with seemed to have less connection with their own pre-existing relationship. They were less likely to forgive a transgression by their partner for example.

However, women, when flirted with, were more likely to forgive their man such mistakes: evidence that they became more committed to their relationship the more temptation was put in their path.

We can all make up a number of possible explanations for this behavior. The traditional evolutionary one, that men are more likely to be interested in spreading it around than women are. Or perhaps a slightly subtler version of the same thing: that men are indeed more likely to wander and the refusal to forgive trifling mistakes was a method of building up the excuse bank, the justifications for why he might be right to stray.

However, my own theory is a great deal less complex and accords much better with my own experience of the world. Men are easily pleased creatures so the risks of switching from one woman to another, from one sequential monogamous relationship to another are fairly low. Finding a decent man is however a rather more difficult prospect….this might be because of the quality of men in general or it might be because women are a little pickier, this makes no difference to the logic here….thus women once they’ve got someone Mr. Half-Right are reluctant to give him up for what they know the average quality of the others in the available pool is.

If you like, for men there are indeed many more fish in the sea while for women there’s only a few with the requisite piscine qualities and an awful lot of pond life floating around them.
