" I have sat through entire conferences on adolescent human behavior without ever hearing the words power and sex, even though to me they are what teen life is all about. When I bring it up, usually everyone nods and thinks it’s marvelously refreshing how a primatologist looks at the world, then continue on their merry way focusing on self-esteem, body image, emotion regulation, risk-taking, and so on. Given a choice between manifest human behavior and trendy psychological constructs, the social sciences always favor the latter. Yet among teens, there is nothing more obvious than the exploration of sex, the testing of power, and the seeking of structure. "
