Now, men report, on average, having had sex with two to four times as many women as women to men. And this does not make sense.
Creswell argues that this results from the difference between the way they count their partners: Men estimate; women enumerate.
She quotes one particularly interesting piece of evidence that this is true: at about 6:06 in the talk she claims that the key piece of evidence is that 80% of mens' estimates of the number of partners is divisible by 5.
Is her hypothesis (that the key explanation of the different reported numbers results from women counting and men estimating) consistent with other research?
