Why Confident People Are Often Wrong (You Need To know This)

The people most convinced they're right are often the ones who understand the least. The people who actually know what they're talking about? They're usually full of doubt. This isn't a coincidence — it's a real, well-documented psychological phenomenon called the Dunning-Kruger Effect. In this video, we break down why confidence and competence don't rise together, why a man once robbed two banks convinced lemon juice made him invisible to cameras, and why real experts often underestimate themselves. 🧠 Sideways Brain explores the weird, hidden science behind why humans think and act the way we do.
