Task difficulty and overconfidence. Evidence from distance running

Publication date: Available online 4 December 2018Source: Journal of Economic PsychologyAuthor(s): Michał Krawczyk, Maciej WilamowskiAbstractIn this project we investigate the impact of task difficulty on overestimation, using data from over 1.6 million amateur distance runners. Overestimation is measured in terms of relative error in forecasted finishing time as well as relative slowing down in the latter half of the course. Longer (esp. the marathon compared to 10km) and slower races are understood to be more difficult than shorter and faster races. Likewise, comparatively slow runners are assumed to be facing a relatively difficult task. The general finding is that greater task difficulty leads to greater overestimation, a clear tendency only weakly moderated by demographic variables such as gender and age.
