Rich As A King Overconfidence Test
Answer the following questions with a range of numbers, not just a single figure. Enter the range (minimum and maximum) of numbers within which you are 90% certain the answer lies. For instance, if the question asks for a specific year, give a range of years between which the particular event occurred. If you have no idea of the answer to a question, then expand your range of possible answers in order to feel 90% confident that the true answer lies somewhere between your two guesses. On the other hand, if you think you can give a good educated guess, then choose a smaller range and still be 90% confident.
