YouTube Description

as posted by the channel

Picture this: you're scrolling through social media, and you come across a famous quote attributed to a well-known business leader. Instinctively, you nod in agreement — after all, if someone that successful said it, it must be true, right?

But as Professor Alex Edmans points out, even genuine statements based on personal experience can be misleading. In this video lesson, he explores how our tendency to trust authority figures, combined with a limited understanding of the circumstances that generated those pithy quotes, can distort the truth behind the claims we often take for granted.
