Leon Festinger

Leon Festinger is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Leon Festinger rather than just read about it. In short: Leon Festinger (8 May 1919 – 11 February 1989) was an American social psychologist who originated the theory of cognitive dissonance and social comparison theory. The rejection of the previously dominant behaviorist view of social psychology by demonstrating the inadequacy of stimulus-response conditioning accounts of human behavior is largely attributed to his theories and research.

Key takeaways

  • Leon Festinger belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Leon Festinger to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Leon Festinger from memory before moving on to harder problems.

Reference excerpt

Leon Festinger (8 May 1919 – 11 February 1989) was an American social psychologist who originated the theory of cognitive dissonance and social comparison theory. The rejection of the previously dominant behaviorist view of social psychology by demonstrating the inadequacy of stimulus-response conditioning accounts of human behavior is largely attributed to his theories and research. Festinger is also credited with advancing the use of laboratory experimentation in social psychology, although he simultaneously stressed the importance of studying real-life situations, a principle he practiced when personally infiltrating a doomsday cult. He is also known in social network theory for the proximity effect (or propinquity). Festinger studied psychology under Kurt Lewin, an important figure in modern social psychology, at the University of Iowa, graduating in 1941; however, he did not develop an interest in social psychology until after joining the faculty at Lewin's Research Center for Group Dynamics at the Massachusetts Institute of Technology in 1945. Despite his preeminence in social psychology, Festinger turned to visual perception research in 1964 and then archaeology, history, and the human evolutionary sciences in 1979 until his death in 1989. Following B. F. Skinner, Jean Piaget, Sigmund Freud, and Albert Bandura, Festinger was the fifth most cited psychologist of the 20th century.

Life

Early life and education Festinger was born in Brooklyn New York on May 8, 1919 to Russian-Jewish immigrants Alex Festinger and Sara Solomon Festinger. His father, an embroidery manufacturer, had "left Russia a radical and atheist and remained faithful to these views throughout his life." Festinger attended Boys' High School in Brooklyn, and received his BS degree in psychology from the City College of New York in 1939. He proceeded to study under Kurt Lewin at the University of Iowa, where Festinger received his MA in 1940 and PhD in 1942 in the field of child behavior. By his own admission, he was not interested in social psychology when he arrived at Iowa, and did not take a single course in social psychology during his entire time there; instead, he was interested in Lewin's earlier work on tension systems, but Lewin's focus had shifted to social psychology by the time Festinger arrived at Iowa. However, Festinger continued to pursue his original interests, studying level of aspiration, working on statistics, developing a quantitative model of decision making, and even publishing a laboratory study on rats. Explaining his lack of interest in social psychology at the time, Festinger stated, "The looser methodology of the social psychology studies, and the vagueness of relation of the data to Lewinian concepts and theories, all seemed unappealing to me in my youthful penchant for rigor." Festinger considered himself to be a freethinker and an atheist. After graduating, Festinger worked as a research associate at Iowa from 1941 to 1943, and then as a statistician for the Committee on Selection and Training of Aircraft Pilots at the University of Rochester from 1943 to 1945 during World War II. In 1943, Festinger married Mary Oliver Ballou, a pianist, with whom he had three children, Catherine, Richard, and Kurt. Festinger and Ballou were later divorced, and Festinger married Trudy Bradley, currently a professor of social work emeritus at New York University, in 1968.

Worked examples

Example 1 — a first encounter with Leon Festinger

Start with the simplest possible case. Write down what Leon Festinger claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Leon Festinger before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Leon Festinger ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Leon Festinger

In research
Leon Festinger appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Leon Festinger in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Leon Festinger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1919 births, 1989 deaths, 20th-century American psychologists, so understanding it makes those chapters shorter.
In everyday life
Look for Leon Festinger outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
