Confidence isn't really about ability. It's about expectation.
Researchers found something fascinating: people feel more confident in situations where they've succeeded before, and more uncertain where they've struggled even when their actual performance in the moment is completely identical.
Your brain isn't measuring your talent in real time. It's running a theory about you, built from what's happened before. And that theory can be wrong.
This is why one bad run, one poor selection, one rough patch can spiral - not because ability has changed, but because the brain's expectation has. And it's also why it can be turned around: the theory isn't fixed. It updates with new evidence, given the chance.
That's the real work. Not "just be confident." Building new evidence, deliberately, until the brain's theory of you catches up with what you're actually capable of.
