In a study headed by Lee D. Ross, David Green, and Pamela House (1976), eighty Stanford University undergraduates were asked if they were willing to walk around campus for at least thirty minutes while wearing a large sandwich board sign that read "Eat at Joe's" and record the responses of their peers to this novel situation. The subjects were not only asked to answer whether or not they would participate, but they were also asked to estimate other people's responses, and make inferences about the disposition of each group of people based on their agreement and disagreement to participate. Overall, the experimenters found that "those who agreed to participate thought that an average of 62% of their peers would agree"; but, those who disagreed with participating thought that an average 33% of their peers would agree to the job". Furthermore, those who agreed had more extreme inferences about the personal dispositions of those who disagreed, and vice versa. The results indicated that the subjects failed to recognize that their peer's construal or interpretation of the situation may be quite different from the perspective they personally take.
