Henri Tajfel

Polish-born British social psychologist, co-originator of social identity theory

1919 to 1982. Born in Poland (Włocławek). Chronology section: Born 1890 to 1919.

Social

Polish-born social psychologist who survived the Second World War as a prisoner of war and held the chair of social psychology at Bristol from 1967. His minimal group studies and social identity theory, developed with John Turner, shaped research on discrimination.

Why this person matters

Tajfel's minimal group experiments showed that trivial categorisation can produce intergroup bias. With John Turner he developed social identity theory. He also helped build European social psychology, and his minimal group paper was written with Michael Billig, R. P. Bundy and C. Flament.

Main contributions

  1. Minimal group paradigm

    Shortly after arriving at Bristol, Tajfel ran experiments in which participants were divided on trivial bases, such as a preference for paintings by Klee or Kandinsky, and then allocated resources. They favoured their own group. The 1971 paper with Billig, Bundy and Flament is a core report.

  2. Social identity theory

    With John Turner he developed the theory that people seek positive distinctiveness through group membership. The European Association page says it is often misread as a theory of discrimination, and that Tajfel intended it as a theory of social change.

  3. European social psychology

    He sat on the first committee of the European Association of Experimental Social Psychology in 1966, served as its second president and was in office when the European Journal of Social Psychology was founded.

Context and limits

Tajfel survived the war as a prisoner of war; nearly all his friends and family died. His biographer Rupert Brown, a former student, confirmed reports that Tajfel sexually harassed young women in his laboratory in the 1960s and 1970s. The European Association of Social Psychology stopped naming its lifetime achievement award after him and renamed its awards in 2020. Brown also calls social identity theory an impoverished explanation of genocide and intergroup violence, because it centres on positive distinctiveness.

In your introductory course

Social psychology.Tajfel appears in prejudice and intergroup relations. Students learn the minimal group effect and social identity as the explanation of in-group favouritism.
