It's one of the perils of theorizing about sex differences: Our own expectations and intuitions get in the way. We hear about a study that reveals a significant sex gap and we immediately jump to conclusions.
Behavioral science has now shown us that many of the gender differences we habitually chalk up to biology or evolution aren't as set in stone as we assume.
What if the presumed sex difference in infidelity isn't as set-in-stone as we assume it is? What if power does predict unfaithfulness, but no more so for men than women?
While men would be wise to grasp the possibility that there are no absolute moral truths, and that not all people have equal needs, women can be encouraged to separate feeling from thinking long enough to protect themselves from unfair treatment.
