Dunning-Kruger effect.

In 1999, psychologists Dunning and Kruger ran a study.

The worst performers consistently overestimated their ability.

The best performers consistently underestimated theirs.

Poker has the same exact curve.

When you first learn something or have your first success, people often believe they are much better than they actually are.

Confidence peaks right when your knowledge is most incomplete.

That’s not a coincidence. That’s the Dunning-Kruger effect.

The beginner is certain he is right,  

the expert is still asking questions, getting feedback, and doubting himself.  

The more you know, the more you understand how little you actually know.

A great player is not the most confident one, the guy who thinks he knows it all.

It’s the one who knows how much he still has to learn. The best players I have met in my life were often the ones doubting themselves the most.
