Video Description

“There's a very pervasive belief that human nature is fundamentally selfish, but I know for a fact that that can't be true in part because my life was saved by a stranger a long time ago when I was 19.” Subscribe to Big Think on YouTube ► https://www.youtube.com/channel/UCvQECJukTDE2i6aCoMnS-Vg?sub_confirmation=1 Up next, Why psychopaths rise to power | Brian Klaas ► https://www.youtube.com/watch?v=PpyIZ4DGIK8 Is it possible that kindness and cruelty aren’t opposites, but points along the same spectrum of human nature?
