What Are Some Social Psychology Experiments?

Social psychology is a fascinating field that studies how people’s thoughts, feelings, and behaviors are influenced by the presence of others. Over the years, researchers have conducted various experiments to gain insights into different aspects of social psychology. In this article, we will discuss some of the most famous social psychology experiments that have shaped our understanding of human behavior.

The Asch Conformity Experiment

One of the most well-known experiments in social psychology is the Asch conformity experiment. Conducted by psychologist Solomon Asch in the 1950s, this experiment aimed to understand how people conform to group norms.

In this study, participants were shown a line and asked to match it with one of three comparison lines. However, all but one participant in each group were confederates who purposely gave incorrect answers.

The results showed that participants often conformed to the incorrect answers given by the confederates, even when it went against their own judgment. This experiment demonstrated the power of social pressure and conformity.

The Milgram Obedience Experiment

Another famous experiment in social psychology is the Milgram obedience experiment conducted by Stanley Milgram in 1963. This study aimed to understand how far individuals would go when ordered to do something by an authority figure.

Participants were asked to deliver electric shocks to another person (who was actually a confederate) whenever they answered a question incorrectly. The shocks increased in intensity with each wrong answer.

Despite hearing screams and protests from the supposed victim, most participants continued delivering shocks up to 450 volts (which was labeled as “XXX” on the machine). This experiment highlighted how easily individuals can be influenced by authority figures.

The Zimbardo Stanford Prison Experiment

The Zimbardo Stanford Prison Experiment conducted by Philip Zimbardo in 1971 aimed at studying how people’s behavior changes when placed in positions of power or subordination. In this study, participants were randomly assigned the roles of prisoners or guards in a simulated prison environment.

The guards quickly began to abuse their power and mistreat the prisoners, while the prisoners became passive and obedient. The experiment was terminated after just six days due to the extreme nature of the behaviors displayed by both groups. This study demonstrated how individuals can quickly adapt and conform to social roles assigned to them.

The Robber’s Cave Experiment

The Robber’s Cave Experiment conducted by Muzafer Sherif in 1954 aimed at understanding intergroup conflict and prejudice. In this study, two groups of boys were brought together at a summer camp but kept apart from each other.

The researchers then created situations that would cause competition between the groups, such as sports tournaments. As a result, the boys began showing signs of hostility towards each other. However, when given tasks that required both groups to work together, such as fixing a water supply issue, the hostility dissipated.

This experiment demonstrated how competition can lead to intergroup conflict but also showed that cooperation can help reduce prejudice and promote positive intergroup relations.


These are just a few examples of some of the most famous social psychology experiments that have helped shape our understanding of human behavior. By analyzing these experiments and their results, we can gain insights into how individuals behave in certain situations and how social norms influence our thoughts and actions.
