Evopshych is not useless, just a tool that's really, really easy to shoot yourself in the foot with. Buyer beware, I guess. It can be done right - for a beautiful example, read or skim Homicide by wilson and daly.
In the context of mating things are complicated by the fact that evopsych itself says that female tastes are very plastic, designed to adapt to whatever is "fit" in each time and society. They're set around puberty, and are much more varied than male tastes. Which I guess is actionable info - there are women that like almost anything, but not much point in trying to conquer every woman. Or even to conquer one particular woman.
