Behave: The Biology of Humans at Our Best and Worst Quotes

“Testosterone has far less to do with aggression than most assume. Within the normal range, individual differences in testosterone levels don’t predict who will be aggressive. Moreover, the more an organism has been aggressive, the less testosterone is needed for further aggression. When testosterone does play a role, it’s facilitatory—testosterone does not 'invent' aggression. It makes us more sensitive to triggers of aggression. Also, rising testosterone levels foster aggression only during challenges to status. Finally, crucially, the rise in testosterone during a status challenge does not necessarily increase aggression; it increases whatever is needed to maintain status. In a world in which status is awarded for the best of our behaviors, testosterone would be the most prosocial hormone in existence.”

“Testosterone makes us more willing to do what it takes to attain and maintain status. And the key point is what it takes. Engineer social circumstances right, and boosting testosterone levels during a challenge would make people compete like crazy to do the most acts of random kindness. In our world riddled with male violence, the problem isn't that testosterone can increase levels of aggression. The problem is the frequency with which we reward aggression.”
