Costs of under-confidence
I don&#x27;t like the tone of the opening anecdote<p>&gt; Had Linda been more confident, we&#x27;d have won.<p>It appears that Linda kept being right.  Regardless, the captain kept not choosing her answers.  Perhaps being a poor captain led to the team&#x27;s defeat, not Linda failing to assert herself properly.  Afterall, a good captain should have experience in the world of pub quizzes, and one would expect that he might have seen this sort of situation before.  Failing that, based with the empirical evidence of Linda being right often, he probably should have picked her answers more frequently.<p>I think the larger lesson here is that confidence is a good thing, but relying on it solely can fail miserably as a substitute for having actual knowledge about something.
