Opinion Change: Information or Partisanship? Evidence from a Natural Experiment

    Research output: Contribution to conferencePaperResearchpeer-review


    Currently two paradigms seek to explain how voters change their opinion when they are confronted with new information. One school argues that voters are bayesian updaters who rationally change their opinion. Another school argues that voters are inherently biased in their evaluation of new information. According to this line of thought voters are more likely to accept information that con_rms their opinion compared to information that contradict their point of view. Using a quasi experiment we investigate the extent to which voters rely on bayesian updating or
    on motivated reasoning when changing their opinions. We show that environmental concerns are more likely to change for voters who are moderately interested in politics and voters who are not strong partisans.
