When asked to resolve a moral dilemma, such as choosing to save five lives from a runaway train by sacrificing one life, oxytocin-sniffing Dutch men more often saved fellow countrymen over Arabs and Germans than those who didn’t get a hormonal whiff.
“Earlier research of oxytocin paints a very rosy view of it. We thought it was odd a neurological system that survived evolution would make people indiscriminately loving toward others,” said social psychologist Carsten De Dreu of the University of Amsterdam, co-author of a Jan. 10 study in the Proceedings of the National Academy of Sciences. “Under oxytocin we saw an increase of in-group favoritism, which has the downside of discrimination against people who are not part of your group.”The questions this raises are interesting. In modern Western society at least, the idea of love is almost a secular religion; it is seen as an unequivocally positive phenomenon, whose only fault is that it is, alas, not everywhere, not washing over everyone and making everything alright. Anyone who dissents from this opinion must be some kind of pitiably twisted curmudgeon; entire subgenres of Hollywood romantic comedies have been made about such sourpusses seeing the light and gaining a new faith in the redeeming power of love, replete with montage sequences. But if the biological conditions underlying the phenomena of love also measurably amplify less positive tendencies, such as reducing empathy to those outside of one's in-group, could love follow religion into becoming something once seen as universally good that has been subjected to more radical reassessment? Perhaps, in future, we'll see the same rational scepticism that has been applied to the virtue of religious faith applied to the universal beneficience of love?
