Conflicts of interest with men
Because males and females can best enhance their fitness in different ways, conflicts of interest between women and men are, unfortunately, an intrinsic part of the mating game.
A man can enhance his fitness by investing in his children and by maxi- mizing his number of mates, but time and resources devoted to one interfere with the other. These trade-offs lead to variation in male strategies, with the polar types immortalized in the words of Draper and Harpending45 as “cads” (low investment males seeking to maximize mating opportunities) and “dads” (high investment males committed to one sexual partner).
The trade-offs facing men define the choices facing women. Should a woman try to secure an investing mate (who may have lower mate value in other respects) or should she content herself with getting good genes and immediate resources from a non-investing cad? She will have trouble doing both at the same time, because the behavior that attracts a cad (flaunting her sexuality) will put off a dad (who wants evidence of fidelity), and vice versa.
