Researchers asked volunteers to read short science articles and judge five statements about each one. Some volunteers answered correctly while reporting that they had guessed. Others answered incorrectly but could point to a relevant sentence and explain why they had rejected one option. A simple score treated the first group as successful and the second as unsuccessful. The researchers added a confidence record with three categories: evidence located, two options remaining, and no evidence located. On a delayed test with new articles, correct guesses were less stable than answers supported by a stated reason. Several incorrect answers with clear evidence were corrected quickly because the remaining problem was the scope of the option, not the passage itself. The study did not claim that confidence predicts every future answer. Instead, it showed that correctness and evidence should be recorded separately when the goal is to decide what to review next.
