Okay, I am being facetious. But a new study found that inhaling oxytocin made study subjects feel more positively about strangers.
ABC News reported on the study by Angeliki Theodoridou, a psychologist at the University of Bristol, UK. This makes sense, because oxytocin has previously been shown to reduce activity in the amygdala, the part of the brain that makes pre-conscious, friend-or-foe decisions. Oxytocin seems to act as a trust signal, letting us gradually approach other people.
Theodoridou was on the team led by Eric Hollander that found oxytocin reduced symptoms of autism and increased adult autistics' ability to detect emotional meaning in speech.
