Who Discovered Social Psychology?

Social psychology is a field of study that explores how people interact with each other and how they are affected by their social environments. The roots of social psychology can be traced back to the late 1800s, but it wasn’t until the early 1900s that the field began to take shape as a distinct discipline.

The Early Years of Social Psychology

One of the first psychologists to explore social behavior was Norman Triplett. In 1897, he published a paper on how the presence of others can affect performance.

He found that cyclists tended to ride faster when in groups than when alone. This research laid the foundation for social psychology as we know it today.

Another early pioneer in social psychology was Max Ringelmann, who studied group dynamics in the early 1900s. He found that individual effort decreased as group size increased, a phenomenon known as “social loafing.”

The Birth of Modern Social Psychology

In the 1920s and ’30s, social psychology began to emerge as a distinct field of study. One of its most important figures was Kurt Lewin, who is often called the “father” of modern social psychology.

Lewin’s research focused on group dynamics and how individuals are influenced by their social environments. He famously developed a model called “field theory,” which suggested that behavior is determined by both individual factors and environmental factors.

Other important figures in the early days of modern social psychology include Muzafer Sherif, Solomon Asch, and Leon Festinger. Their research focused on topics such as conformity, obedience, and cognitive dissonance.

The Rise of Experimental Social Psychology

In the 1950s and ’60s, experimental methods became more prominent in social psychology research. This led to an increased focus on understanding how people form attitudes and make decisions.

One of the most famous experiments in social psychology is the Milgram experiment, conducted by Stanley Milgram in 1961. This study showed how people can be influenced to obey authority figures, even when it goes against their own moral beliefs.

Another influential figure in experimental social psychology was Elliot Aronson, who studied cognitive dissonance and how people justify their actions. His book “The Theory of Cognitive Dissonance” is still widely read today.


In conclusion, social psychology has a rich history that spans over a century. From the early work of Norman Triplett and Max Ringelmann to the groundbreaking experiments of Kurt Lewin and Stanley Milgram, social psychology has evolved into a diverse and dynamic field of study.

Today, social psychologists continue to explore how people interact with each other and how they are influenced by their social environments. With new research methods and technologies constantly emerging, there is no doubt that this field will continue to evolve and grow in the years to come.
