This is not necessarily true. In may pub quizes I've been part of, there are multiple rounds of 5-10 questions each where the answers are given after each round. This keeps teams engaged and heightens the mood since there are running totals for each team. Had the captain been better, he could have picked out which teammates (presumably, Linda) had been better predictors of the correct answer. Instead he chose confidence as the metric.
