Compliance without pressure: the foot-in-the-door technique.

2 experiments were conducted to test the proposition that once someone has agreed to a small request he is more likely to comply with a larger request. The 1st study demonstrated this effect when the same person made both requests. The 2nd study extended this to the situation in which different people made the 2 requests. Several experimental groups were run in an effort to explain these results, and possible explanations arc discussed.
