Sure. People who don't know how little they know are likely to be overconfident, misjudge their abilities, and make mistakes. Did they really need to do a study to find that out?

But sometimes it's people who get many things right who become overconfident and eventually stumble badly. And the people who've learned not to be overconfident often come to that wisdom by having made many mistakes in the past. Not sure where that leaves us.

By the time you’re well into adulthood, most people know their strengths and weaknesses.
