Only Hearing What You Want
We collect the facts that agree with us and skip right past the ones that don't.
The idea
Once we like an idea, our brain starts hunting for reasons it's right and quietly walks past the reasons it's wrong. That's confirmation bias. It feels exactly like research, but you're really just collecting cheers for something you already believed. The repair is simple and uncomfortable: go looking on purpose for the strongest case against your idea, and see whether it still stands up. 🔎
