We discuss the results of a study on the acceptance and effectiveness of cognitive and moral nudges using defaults and social information as examples. Our study participants classify these two dimensions of nudges differently. In addition to the choice mechanisms of nudges, this article also focuses on differences in social and personal goals in which nudges are to be applied. Our result is that moral nudges are preferred for social goals, whereas cognitive nudges are preferred for personal goals. From this we derive important consequences for the use of nudges as policy measures. Our results show that cognitive nudges are considered more effective by our study participants than moral nudges. However, the acceptance of such nudges differs according to the goals.
