jan 1, 1966 - Freedman & Fraser Content Persuasion and Foot in the Door Technique

Description:

Freedman and Fraser had a researcher go door-to-door in a suburban area in California, and asked them to put a "Drive Carefully" sign in their window. A simple request, yes. But, then two weeks later, they went door-to-door in the same neighborhood and asked the homeowners if they could put a large and ugly "Drive Carefully" sign in their yard. Of the homeowners who did not agree to the first sticker, 17% agreed, and of the homeowners who agreed to the first one, 76% said yes to the sign (a 400% difference!)
