Working Paper No. 2023-15 - 20 March 2024 - Increasing the acceptability of

The considerable reduction in strong opposition toward carbon taxation (both initially and in the follow-up) represents an upward shift at the lower end of the policy prefer- ence distribution and could thus be interpreted as a shift in the Overton window, i.e., the range of acceptable discourse. [...] Furthermore, we systematically collect predictions of academic experts (DellaVigna and Pope, 2018) to evaluate the discrepancy between the wisdom of the crowd and the actual effectiveness of specific information interventions in the climate policy domain. [...] In section 5 we present the persistence of the effects generated by the video interventions in the follow-up survey. [...] For political economy considerations, the full distribution of views in the population matters, so we examine the effects of the video interventions not only on the share of individuals who support the policy, but also on the share of individuals who strongly oppose it. [...] In our own study, more than half of the subjects in the Control and Norm groups agree to the banning statement and more than 7 out of 10 subjects agree to the funding statement.
