Our study examined the question of whether people’s self-described reactions to the violation of social norms (defined as slightly inappropriate behavior) are accurate with respect to people’s actual reactions to the same norm violations. We recruited undergraduate students to participate in data collection sessions under the cover story that the project was about birth order and personality. Participants were randomly assigned to one of four conditions, a control condition during which no social norm violations occurred, but participants were asked to predict (hypothetically) how they would react to such violations, and three conditions during which the researcher’s behaved in a slightly inappropriate way (laughing, avoiding eye contact, and walking around the room all while providing participants with information). Participants in all four conditions were given the opportunity to express their reactions to the researchers’ behavior via survey questions presented at the conclusion of each experimental session. The key question in analysis is whether participants reacting hypothetically (in the control condition) are more (or less) accepting of social norm violations than are those participants who actually experienced the inappropriate behavior. We will also describe how reactions differed across the three different social norm violation conditions.
