Who Started Social Psychology?

Social psychology is a fascinating field that seeks to understand how individuals interact with each other in social settings. But who started social psychology? Let’s dive into the history of this field and explore its origins.

The Early Years

Social psychology can trace its roots back to the late 19th century, when the discipline of psychology was still in its infancy. One of the earliest pioneers in social psychology was Norman Triplett, who conducted a study in 1898 on how the presence of others affects performance. He found that cyclists performed better when racing against each other than when racing alone.

Another early contributor to social psychology was Gustave Le Bon, a French psychologist who wrote The Crowd: A Study of the Popular Mind in 1895. In this book, Le Bon explored how individuals behave differently when they are part of a crowd, and argued that crowds have a distinct “psychology” that can be studied.

The Birth of Social Psychology

Despite these early contributions, social psychology as a distinct field didn’t truly emerge until the early 20th century. One key figure in this emergence was Floyd Allport, who published Social Psychology in 1924. Allport defined social psychology as “the study of the nature and causes of human behavior in relation to other individuals.”

Around the same time, psychologists like Kurt Lewin were beginning to conduct experiments on group dynamics and social influence. Lewin’s work laid the foundation for many key concepts in social psychology today, including group polarization and conformity.

Modern Developments

Since its emergence as a distinct field, social psychology has continued to develop and evolve. Today, researchers examine topics ranging from prejudice and discrimination to interpersonal attraction and relationships.

Some notable modern figures in social psychology include Stanley Milgram (known for his controversial obedience experiments), Elliot Aronson (who developed the concept of cognitive dissonance), and Muzafer Sherif (who studied intergroup conflict and cooperation).


Although social psychology has a relatively short history compared to other scientific disciplines, it has had a significant impact on our understanding of human behavior. From early pioneers like Norman Triplett and Gustave Le Bon, to modern researchers like Stanley Milgram and Elliot Aronson, social psychology has come a long way in its quest to unravel the mysteries of how we interact with one another.
