Abstract

The role of social identity variables for predicting environmental decisions may often be underdetected by psychological lay people. Applying this to the acceptance of electric vehicles (EVs) in Germany we investigated whether social norms and collective efficacy predict EV acceptance and what psychological laypersons who are either EV experts or EV non-experts think predicts EV acceptance. In preliminary interview studies we explored the beliefs of EV experts and EV non-experts. In a survey study, we then tested whether cost-related advantages and disadvantages were predictive of EV acceptance and whether norms and collective efficacy have independent effects even when controlling for cost-related factors and demographic variables.

RESULTS suggest that both EV experts and EV non-experts considered cost-related factors as much more important than social identity processes. However, hierarchical regression analyses of the survey data showed that norms and collective efficacy have equal or even stronger effects on acceptance than cost-related factors. We discuss the theoretical and practical implications of these findings.
