it's also been proven that men over exaggerate their numbers due to social pressure stud status, you ain't a man unless you are fucking a different bitch every night init and on the other hand women under report their numbers because of the social stigma of being the local bike branded a dirty slag
That's what the researchers say innit.
Personally though I'm not so sure. The surveys are anonymous, so there seems no reason to lie. Unless they're lying to themselves, which I guess is possible. But I think it's more likely that 80% of the women really are chasing 20% of the men. That's what I'd do if I was a woman-actually I'd chase just the top 1%, because the vast majority of men are hideous creeps.
