The cosmetics industry is a reflection of female-female competition
Even if men have good grades, women don't like acne, allergies, ectomorphs, loners, fatties, geeks, and the lopsided (Buss, 1999; Miller, 1998, 2000). Women also strive mightily to repair these things in their flawed sons.

(The cosmetics industry is a reflection of female-female competition, not just of lies that allure males.) Whether in groups of wolves, rhesus, chimps, or fans of Nat Angier, offspring have different opportunities as a function of mother's social position.
