The Barnum effect in a group setting.

The present study expands the typical Barnum effect paradigm by investigating reactions to feedback in a group setting. People initially participated in a group experience (8 per group), and then were given bogus positive or negative feedback (the favorability manipulation) purportedly prepared by either the group leader or another group member (the source status manipulation). The answerability manipulation led participants to believe that they either would or would not have to share their reactions to the feedback with the person who prepared it. Positive feedback was rated as more accurate and accepted more highly than the negative feedback, though no differences in recall of either the positive or negative feedback emerged. Additionally, a pattern of results revealed that the feedback from the group leader generated greater perceived accuracy, acceptance, and recall than did feedback from another group member. Implications for the impact of feedback given by a high status person in group settings are discussed.
