So does experience really make you an expert? What does it actually mean to be one? It turns out, we don’t learn from experience in many contexts.

You’re really good—an expert even one might say—at many things. But being really good at something… Having a lot of experience doing that something… Does that make you an expert? I think those things are not sufficient. To be an expert one must also explicitly understand the principles underlying the activity. I’m very good at sitting on chairs—but I’ve never studied chairs; their design, their mechanical structure, their aesthetics. I’m not expert.
