cash and all the subject had to do was tell the other student arriving that the experiment was interesting. The Subjects agreed, and duly informed the arriving student that the experiment was indeed interesting. Surprisingly, this arriving student (an actress), then told the subject that her friend had done the experiment, found it really boring, and encouraged her to get out of doing it. To this, some subjects put the university to arrive and ask about the experiment he just did. However, whilst he is waiting, the experimenter pops his head in at reception and rather embarrassed, informs the subject that the student who is running the experiment for Group B has not turned up, so would he mind doing it for them? It would only take a few minutes and they will pay him a $1. Another set of students having just done exactly the same procedure and, receiving the same explanation about the student not turning up, are offered $20. Remember, it’s 1959 so even a $1 is useful 22
