Some of the science around oxytocin is good, and some of it is so tainted with stereotypes of femininity that we might as well dress it up in a frilly pink tutu: “Oxytocin makes you love your baby.” “Oxytocin makes you love your man.” “Monogamous men make more oxytocin than men who’re going to cheat on you.” While oxytocin does seem to be associated with a number of psychological states in various mammals, and higher levels of oxytocin are associated with more pro-social behaviors, there are simply too many other factors that produce these things to treat oxytocin as a solo player.
