The following list is probably not exhaustive, but it covers most of the types that have been used. It is also very robust across type of tasks. It has been found in general-knowledge questions, in political or business developments, in predictions of elections or sport results, in medical diagnoses or in personality assessment, to name only a few. The phenomenon is very robust across content domains. Generally, hindsight bias is said to exist whenever the estimates made in hindsight lie closer to the solution than those made in foresight, and when the measure that captures this difference is significantly larger than for a control group. In the control situation, other people are asked for their answers without giving them the solution beforehand. In the hypothetical design, people receive the solution right away and are then asked to provide the answer they would have given without this knowledge. In the control situation, the same items are given to other people without providing them with the solution before they recall their original answer. In the memory design, people first give an (unbiased) answer, then receive the solution and are finally asked to recall their earlier, original answer. Two different general experimental procedures are usually employed. Designs, Materials, and Measures of Hindsight Bias
