Lot of comments are saying confidence, not overconfidence. Very different things. Confidence is great, in both you and others you are "entrusting" somehow. The problem is lack of competence.
What is the definition of overconfidence. I'd argue being less competent than your confidence warrants. Where as if you're competent then being confident is "correct". The difference is whether someone is competent or not. Not if they are confident or not.
The problem is not confidence. It's peoples in ability to gauge competence / using confidence as an indicator of competence. Which is what the OA says, but many comments here are diverging from that and going off on tangents about confidence.
