"In experiments, volunteers who sniffed sweat samples from people experiencing certain feelings, such as fear or disgust, felt those emotions themselves. When volunteers smelled the odor of disgusted people, their lips curled just as they do when smelling something disgusting, says Dalton"
Interesting article. I'm curious as to how much reliable research has been done into contagious emotions. It sounds a bit farfetched the way they describe it in the quote above. The idea is talked about in a Live Science article too [0], but also not much detail is given. I haven't read much about it, but it sounds like one of those single paper non-reproduced ideas that's interesting enough on its own for people to keep talking about it. Does anyone who knows more about this than me have other opinions?
