#Fighteverycrisis: A psychological perspective on motivators of the support of mitigation measures in the climate crisis and the COVID-19 pandemic.

Both crises, the climate crisis and the COVID-19 pandemic need collective mitigation support. In the context of COVID-19, the support of mitigation strategies has found its way to the forefront of debates. Our aim was to contribute empirical evidence to this debate by investigating mitigation behaviors across both crises and discussing similarities and differences. To this end, we drew on the Norm Activation Model and the concept of Social Identity to understand individuals' support of mitigation strategies in the climate crisis and their support of governmental strategies to mitigate the spread of the virus. Data were gathered within a Germany-wide survey ( = 3092) carried out in June and July 2020. Three predictors significantly explained the support of mitigation strategies in both crises: (1) by the pandemic emerged as the strongest predictor for support of COVID-19 mitigation strategies, whereas (2) with others making efforts to mitigate the climate crisis was the strongest predictor for support of climate crisis mitigation strategies. (3) that together with others one can make a substantial contribution to mitigate the respective crisis predicted support of mitigation strategies in the COVID-19 pandemic and the climate crisis to similar proportions. The results point to the need for targeting the communication of mitigation strategies in a pandemic on raising awareness for the collective nature of the problem whereas strengthening efficacy expectations and feelings of belonging, e.g. through participation processes, could generally strengthen the support of mitigation strategies in both crises.
