Only if you are truly open to the possibility of being wrong can you ever learn, says researcher Alex Edmans. In an insightful talk, he explores how confirmation bias -- the tendency to only accept information that supports your personal beliefs -- can lead you astray on social media, in politics and beyond, and offers three practical tools for finding evidence you can actually trust. (Hint: appoint someone to be the devil's advocate in your life.)
