On June 4, 2026, we published a page titled "Do We Tend to Set 'Forecasts' Too Optimistically? The 'Planning Fallacy'." The 'Planning Fallacy' refers to the psychological phenomenon where the time, costs, and risks required to complete tasks are "underestimated," while the benefits are "overestimated." The page explains examples of its occurrence, the factors that lead to it, and methods to overcome it.
