Women are better at reading emotions from other people's facial expressions than men are. A new study suggests that oxytocin, the sociability-inducing hormone that women get by the bucketload from childbirth, boosts mood-reading. Researchers in Zurich found that men could also read moods from faces much better after they were sprayed with synthetic oxytocin -- but only for a short time.
So, gentlemen, if you ever find yourself caught in an "if you really loved me you'd read my mind" loop, carry a discrete supply of oxytocin in a nasal sprayer and give yourself an edge. Think of it as leveling the playing field.
Who knows, maybe someday they will put the stuff in the water supply, like fluoride, to improve social life.
