You Never Noticed Why Yawns Are Contagious

You're sitting in a meeting. Someone yawns. You yawn too, without deciding to. It feels meaningless. It isn't. In this video, you'll discover why your brain reflexively catches other people's yawns — and why that reflex has nothing to do with being tired. You'll trace the science from Robert Provine's early experiments, through Atsushi Senju's research on empathy and autism, to Elizabeth Cirulli's twin studies on genetics, all the way back to a theory about brain temperature and survival among your earliest ancestors. What starts as an involuntary twitch in a boardroom turns out to be one of the oldest forms of communication your species ever developed.
