I do, therefore i think it is normal: the causal effects of behavior on descriptive norm formation and evolution

Abstract

Social norms theories have guided social science research by predicting how and when social norms influence people’s behavior. However, there are still gaps in our understanding of how social norms are formed, maintained, and changed. It is possible that our own actions shape and perpetuate what we believe is normal. This study tests whether behavior can influence perceptions of what is typical behavior and how this relationship evolves over time. Secondary analysis of data from a multi-round public-goods experiment showed that personal contribution behavior significantly and positively influences perceived descriptive norms; yet, a significant change in the relationship over time was not evidenced. Theoretical and practical implications are discussed.
