Titre de sa présentation : Green Nudges and Information Avoidance, Experiment with Farmers from Five European Countries.

Résumé : We investigate why farmers actively avoid information related to the environment and how it affects the effectiveness of information campaigns. We administered a preregistered experiment on farmers and foresters from Italy, Belgium, Lithuania, France and Finland. We collected two samples: one where respondents could skip information about the economic benefits of implementing environmentally sustainable farming practices, and another composed of a treatment group where respondents were shown the information, and a control group. Around 39% of farmers and forest owners actively avoid the information in the first sample. Distrust in scientists and low pro-environmental attitudes correlate positively with information avoidance. The information treatment increases respondents' willingness to implement environmentally sustainable practices in the second sample. Using machine learning, we find that those with a similar profile to the information avoiders of the first sample drive the effect of the nudge. This suggests that a reason why information campaigns fail is because the most amenable are also those that tend to avoid information.
