Consider a trivia test consisting of 10 questions for you to answer from memory alone.In addition to giving your best guess, consider a range: a low guess and a high guess so that you feel 90 percent confident that the right answer will lie between your low guess and your high guess. Try not to make the range between your low guess and high guess too narrow. Otherwise, you will appear overconfident. At the same time, try not to make the range between your low guess and high guess too wide. This will make you appear underconfident. If you are well-calibrated, you should expect that only one out of the 10 correct answers you provide does not lie between your low guess and your high guess.
After each question, write down three numbers, your best guess, low guess, and high guess.25
