So Briffault's law states "Where the female can derive no benefit from association with the male, no such association takes place."

Does the same law not apply to men? If a man derives no benefit from associating with a female, does any association take place? I'd say no. Maybe the benefits are different but the statement applies if you switch the genders in the law.

You show me a guy that spends time with a woman, and I'll show you someone that at least believes they are receiving some sort of benefit even though they may actually be deluding themselves.
