Have you ever done something you didn't really want to do simply because someone else asked you to? Buying something after being persuaded by a pushy salesperson or trying a particular brand of soda after seeing a commercial endorsement featuring your favorite celebrity are two examples of what is known as compliance.

What influence does it have on our social behavior? Are there any factors that impact compliance? In order to learn the answers to these questions, it is important to start by understanding exactly what compliance is and how it works. Continue reading to discover more about what researchers have learned about the psychology of compliance.

What Is Compliance?

In psychology, compliance refers to changing one's behavior due to the request or direction of another person.

Unlike obedience, in which the other individual is in a position of authority, compliance does not rely upon being in a position of power or authority over others.

Compliance involves changing your behavior in some way because someone else requested you to do so. While you may have had the option to refuse the request, you chose to comply.

There are many different kinds of situations where compliance comes into play. Some examples include:

  • Buying something because a salesperson makes a pitch and then asks you to make a purchase
  • Responding to a friend asking "Can you do me a favor?"
  • Seeing an ad on a website, clicking it, and then making a purchase

As you can see, sometimes compliance can involve a direct request. Someone asks you specifically to do something and you do it. In other cases, the request may be much more subtle and even insidious.

Techniques Used

Compliance is a major topic of interest within the field of consumer psychology. This specialty area focuses on the psychology of consumer behavior, including how sellers can influence buyers and persuade them to purchase goods and services. Marketers often rely on a number of different strategies to obtain compliance from consumers.

Some of these techniques to gain compliance include the following:

The "Door-in-the-Face" Technique

In this approach, marketers start by asking for a large commitment. When the other person refuses, they then make a smaller and more reasonable request.

For example, imagine that a business owner asks you to make a large investment in a new business opportunity. After you decline the request, the business owner asks if you could at least make a small product purchase to help them out. After refusing the first offer, you might feel compelled to comply with their second appeal.

The "Foot-in-the-Door" Technique

In this approach, marketers start by asking for and obtaining a small commitment. Once you have already complied with the first request, you are more likely to also comply with a second, larger request.

For example, your coworker asks if you fill in for them for a day. After you say yes, they then ask if you could just continue to fill in for the rest of the week.

The "That's-Not-All" Technique

Have you ever found yourself watching a television infomercial? Once a product has been pitched, the seller then adds an additional offer before the potential purchaser has made a decision. "That's not all," the salesperson might suggest, "If you buy a set of widgets now, we'll throw in an extra widget for free!" The goal is to make the offer as appealing as possible.

The "Lowball" Technique

This strategy involves getting a person to make a commitment and then raising the terms or stakes of that commitment. For example, a salesperson might get you to agree to buy a particular cell phone plan at a low price before adding on a number of hidden fees that then make the plan much more costly.


This approach involves gaining approval from the target in order to gain compliance. Strategies such as flattering the target or presenting oneself in a way that appeals to the individual are often used in this approach.


People are more likely to comply if they feel that the other person has already done something for them. We have been socialized to believe that if people extend kindness to us, then we should return the favor.

Researchers have found that the reciprocity effect is so strong that it can work even when the initial favor is uninvited or comes from someone we do not like.


There are a number of well-known studies that have explored issues related to compliance, conformity, and obedience. Some of these include:

The Asch Conformity Experiments

Psychologist Solomon Asch conducted a series of experiments to demonstrate how people conform in groups. Participants were shown three lines of different lengths, then asked to select which line matched a fourth "standard" line. When others in the group (who were planted) selected the wrong line, many participants would conform to group pressure and also select the wrong line length.

The Milgram Obedience Experiment

Stanley Milgram's famous and controversial obedience experiments revealed the power of authority could be used to get people to obey. In these experiments, participants were directed by the experimenter to deliver electrical shocks to another person.

Even though the shocks were not real, the participants genuinely believed that they were shocking the other person. Milgram found that 65% of people would deliver the maximum, possibly fatal electrical shocks on the orders of an authority figure.

The Stanford Prison Experiment

During the 1970s, psychologist Philip Zimbardo conducted an experiment in which participants played the roles of guards and prisoners in a mock prison set up in the basement of the psychology department at Stanford University.

Originally slated to last two weeks, the Stanford prison experiment had to be terminated after just six days after the guards began displaying abusive behavior and the prisoners became anxious and highly stressed. The experiment demonstrated how people will comply with the expectations that come from certain social roles.

Key Factors

Below are important factors that influence compliance:

  • Being in the immediate presence of a group makes compliance more likely.
  • People are more likely to comply when they believe that they share something in common with the person making the request.
  • The likelihood of compliance increases with the number of people present. If only one or two people are present, a person might buck the group opinion and refuse to comply.
  • When group affiliation is important to people, they are more likely to comply with social pressure. For example, if a college student places a great deal of importance on belonging to a college fraternity, they are more likely to go along with the group's requests even if it goes against their own beliefs or wishes.
