Figure 2. An appeal to descriptive norms reduces beliefs that others stockpile.
Study 1 elicited beliefs and reports of people’s own behaviour. In Study 2, half of the participants were informed about the true rate of stockpiling in Study 1 (‘Treated’). The other half did not receive any message (‘Control’). Histograms and density plots show the distribution of beliefs about the percentage of others who engage in stockpiling. Solid blue bars show the median belief; dashed red bars show the actual rate of self-reported stockpiling for each wave.
