Psychologists (especially social psychologists) have been researching manipulation techniques for decades. It is becoming increasingly apparent that sometimes it only takes a single phrase to increase the likelihood that another person will comply with our request. The following techniques seem to be particularly effective:

1. “Evoking freedom” technique

2. “This is my only request” technique.

3. Legitimization of a paltry contribution technique.

4. “You will probably refuse…” technique

5. Foot-in-the-mouth technique

Since these manipulation techniques can be easily incorporated into everyday speech and many people do this automatically anyway, they are difficult for us to recognize. Nevertheless, as is often the case, the more familiar we are with these techniques, the better we can protect ourselves against them.

About: Social Psychological Influence Techniques

Social psychological influence techniques are behaviors aimed at influencing the opinions or actions of others. They are used in many areas of daily life, from sales promotion to political campaigning. Some of the most well-known social psychological influence techniques are the foot-in-the-door technique, the door-in-the-face technique, the low-ball technique, and the that’s-not-all technique.

The “foot-in-the-door” technique is based on the assumption that people are more willing to fulfill a larger request after they have already fulfilled a smaller request. A well-known study that examined this technique is that of Freedman and Fraser (1966). In this study, the researchers first asked for a small favor (e.g., to hang a small sign) before asking for a larger favor (e.g., huge sign in the front yard). The results showed that those who had initially performed the small favor were more willing to perform the larger favor as well.

The door-in-the-face technique is based on the assumption that people are more willing to fulfill a smaller request after refusing a larger request. A well-known study that examined this technique is that of Cialdini et al. (1975). In this study, researchers first asked for a very large favor (e.g., to participate in a study for a week) before asking for a smaller favor (e.g., to complete a questionnaire). The results showed that those who had initially refused the large favor were more willing to perform the smaller favor as well.

“How are you feeling?”

Does this simple phrase improve compliance rates?

What happens if you combine scientifically proven persuasion techniques?

The foot-in-the-door technique is certainly one of the best-known and best-researched influence techniques. Usually only the study by Freedman and Fraser (1966) is presented in psychology textbooks.
Meanwhile, foot-in-the-door technique has been tested in many other situations.
For example when it comes to begging money or to invite a woman to a date.
In recent years attempts are being made to improve the effectiveness of foot-in-the-door technology …

The Door-in-the-Face-Technique is one of the most famous influence techniques. It’s effectiveness could be shown in many different studies.
But does it work with children as well?
