With all the research supporting that the Foot-In-The-Door Technique is a successful compliance technique, there is a big question as to why humans tend to follow this pattern. The most well-known theory explaining the reasoning behind this is the self-perception theory. When a person has originally agreed to something, he/she will answer a question to themselves about why he/she agreed to these questions and when he/she came to the decision that it was truly their desire and nothing else influenced the answer, he/she will feel the need to stay consistent with their decision and will agree to a larger request.[17] The self-perception theory was developed by Daryl Bem, a social psychologist and retired professor from Cornell University, and claims two things: One is that people come to their beliefs and attitudes based on what they enjoy doing and if there is a positive or negative outcome on an experience.
