Reverse psychology Research investigating reverse psychology showed that participants used the DITF technique in their everyday lives. They also use other reverse psychology tactics, such as FITD. There were two studies that looked at participants' own experiences using reverse psychology, which these researchers refer to as strategic self-anticonformity. The first study consisted of an open-ended questionnaire that asked participants about instances in which they used strategic self-anticonformity. The second study asked about specific instances of different types of strategic self-anti-conformity, like DITF and FITD. Findings indicate that most of the participants could provide examples of their own use of reverse psychology tactics and that a likely explanation for this is a need for social reassurance. Monetary solicitation A study looking at behavioral, not just verbal, compliance to donate money found that the DITF technique was effective. The study involved male and female confederates who ordered lemonade at a restaurant and engaged in conversation before the male announced loudly that he was leaving to buy a part for his bicycle. After he left the female confederate expressed aloud that the male did not pay and asked the participant sitting near her to pay the total bill. In the DITF condition, the female confederate asked if the participant would pay part of the bill after a refusal to pay the total bill from every participant. In the control condition the female confederate only made the second smaller request. The DITF technique yielded significantly more behavioral compliance than the control, which shows that the DITF technique works for more than just verbal agreement. Retail A study looking at the DITF technique in retail found that it was very effective in increasing sales. In this study the experimenter sold cheese to people walking past a hut in the Austrian Alps. The experimenter rotated between five conditions: a DITF condition in which the experimenter first tried to sell two pounds of cheese at eight euros and then one pound of cheese at four euros, a DITF condition with an emphasis on concession in which the experimenter said that two pounds was probably too much anyway, a DITF condition with an emphasis on credibility of the experimenter, who wore traditional clothes and spoke in a mountain dialect, a DITF condition with both an emphasis on concession and credibility, and a control condition in which the experimenter only made the smaller second request. Results show increased compliance
