Visualization-Mediated Alleviation of the Planning Fallacy

Pierre Dragicevic, INRIA, Paris, France and Yvonne Jansen, University of Copenhagen, Denmark

The planning fallacy, i.e., people’s tendency to underestimate the time required to complete a project despite past failures, is ubiquitous and resistant to coping strategies. We propose scenarios where visualizations may help alleviate this problem, motivated by previous research in psychology. We hope that with the help of visualizations, people will become more reliable in their judgments and work together in a way that is both more productive and more gratifying.
