Reading between the lines: An exploratory study on how graph distortions shape perceptions and use of performance information

This study examines how graph distortion affects politicians and their staff. Using an experimental design with crime rate graphs, the authors investigated the impact on trend assessment, perceived informational value, and intentions to use performance information. Graph distortion was found to significantly affect politicians’ trend evaluations and the latter correlated with increased intentions to use performance information for citizen communication. This was, however, not true for staff. Individual characteristics, for example indicator attitude and opposition status, proved to be more influential than visual manipulations.
