Elliot Aronson (born January 9, 1932) is an American psychologist. He is listed among the 100 most eminent psychologists of the 20th Century and is best known for the invention of the Jigsaw Classroom as a method of reducing interethnic hostility and prejudice. He is also known for his research on cognitive dissonance and his influential social psychology textbooks.[4] In his (1972) text, The Social Animal, (now in its 11th edition), he stated Aronson's First Law: "People who do crazy things are not necessarily crazy," thus asserting the importance of situational factors in bizarre behavior. He is the only person in the 120-year history of the American Psychological Association to have won all three of its major awards: for writing, for teaching, and for research.[3] In 2007 he received the William James Award for Lifetime Achievement from the Association for Psychological Science, in which he was cited as the scientist who "fundamentally changed the way we look at everyday life.” [5] A Review of General Psychology survey, published in 2002, ranked Aronson as the 78th most cited psychologist of the 20th century.[6] He officially retired in 1994 but continues to teach and write.[7]

Early life and education

Aronson grew up in extreme poverty in Revere, Massachusetts, during the Great Depression. His was the only Jewish family in the neighbourhood, and it was not rare for Aronson to be bullied on the way home from Hebrew school by anti-Semitic gangs. He believes that every life's progress is based on a combination of luck, opportunity, talent, and intuition.[8] Although his high school grades were mediocre, his SAT scores were high enough to earn him a work-study scholarship at Brandeis University.[1]

Influenced by his father, he began his college career majoring in economics. However, he promptly changed his major to psychology after accidentally wandering into an Introductory Psychology lecture taught by Abraham Maslow.[9] After attending this lecture, he realized that there was an entire science devoted to exploring the kinds of questions that had intrigued him as a child.[9] His undergraduate years at Brandeis brought him closer to a number of respected psychologists, but Maslow was his primary mentor and had the biggest impact on his early academic career.[9]

Aronson earned his Bachelor's degree from Brandeis in 1954. He went on to earn a Master's degree from Wesleyan University in 1956, where he worked with David McClelland, and a Ph.D. in psychology from Stanford University in 1959, where his doctoral advisor and mentor was the experimental social psychologist Leon Festinger.[1][2]

Professional history

Aronson has taught at Harvard University, the University of Minnesota, the University of Texas, and the University of California, Santa Cruz. He also served as Distinguished Visiting Professor at Stanford University.[10] He was included in a list of the 100 most influential psychologists of the 20th century published by the Review of General Psychology.[4] He was elected to the American Academy of Arts and Sciences and won the William James Award from the Association for Psychological Science for his lifetime achievements.[11] His honors include distinguished research awards from the American Psychological Association, the American Association for the Advancement of Science and the Society of Experimental Social Psychology. He also won the Gordon Allport Prize for his work on reducing prejudice.[12] In 1981 he was one of five academics awarded "Professor of the Year" by the Council for the Advancement and Support of Education.[13]

Research topics

Cognitive dissonance

One of Aronson's key areas of interest and research has been the theory of cognitive dissonance.[14] Aronson refined the theory, which posits that when attitudes and behaviors are inconsistent (dissonant), psychological discomfort results. This discomfort motivates the person experiencing it to either change the behavior or the attitude so that consonance is restored. In a classic experiment, Aronson demonstrated that people who undergo an embarrassing initiation to gain admission to a group develop more favorable evaluations of the group than people who are admitted after a mild or easy initiation.[15] In Aronson's Theories of Cognitive Consistency, he states: "Dissonance theory does not rest upon the assumption that man is a rational animal; rather, it suggests that man is a rationalizing animal – that he attempts to appear rational, both to others and to himself."[16]

The Jigsaw Classroom

Aronson led the development of a classroom technique for defusing inter-group tension and promoting self-esteem. In 1971 the newly desegregated schools of Austin, Texas faced a crisis of violence between ethnic groups.[17] Aronson, then at the University of Texas, was called in as a consultant by a school superintendent who was also a former student.[2][17] Aronson noticed that the schools' highly competitive atmosphere was exacerbating the already tense ethnic rivalry.[2] Together with his graduate students, he developed a model of teaching practice to encourage a culture of shared goals and mutual support.[2] In the jigsaw classroom approach, pupils are divided into small groups, mixed by race and by ability, to work co-operatively on a task.[18] The classroom material—for example a biography of a historical figure—is broken into sections, and one member of each group is responsible for reading each section.[18] Members with the same role from each group gather in "expert groups" to discuss their sections. They then return to their own groups and take turns to present what they have learned. They are then assessed individually on all sections of the material.[18][19][20] This division of responsibilities means that students are motivated to listen to each other and each of them experiences a role in which they are valuable to others.[18]

Comparisons with traditional classroom environments showed that the jigsaw classroom has positive effects on academic performance, self-esteem and attitudes towards other ethnic groups.[21] The technique has since been applied in hundreds of schools across North America.[2] From its initial application at third- to fifth-grade school level, it has been expanded to other educational levels. This success encouraged Aronson to apply his research to other policy issues including energy conservation and the treatment of the elderly.[2] In the aftermath of the Columbine High School massacre, Aronson advocated for jigsaw classrooms as part of an approach to defusing the social divisions underlying school violence.[17]

Gain-loss theory of attraction

In 1965, Aronson proposed that interpersonal attraction and liking could be understood in terms of the balance of reward and cost. This implied that contrast—a gain or loss of positive feedback from the other person—has more effect on liking than the absolute level of feedback. An example is how compliments are more meaningful when they come from someone who is usually critical, rather than from a reliable supporter. Another example is that a couple may feel more dedicated to their relationship if they initially disliked each other.[22]

Pratfall effect

Aronson published a paper in 1966[23] where he described an experiment testing the effects of a simple blunder on perceived attraction. The so-called Pratfall effect is the tendency for attractiveness to increase or decrease after an individual makes a mistake, depending on the individual's perceived competence, or ability to perform well in a general sense.

Personal life

Elliot is married to Vera Aronson, whom he met while they were both undergraduate research assistants under Abraham Maslow.[3] Together they have had four children: Hal, Neal, Julie and Joshua, who is himself a social psychologist.[3][27] In 2000, Aronson was diagnosed with macular degeneration and, by 2003, had lost all of his central vision.[11] To cope with his blindness, Aronson decided to get a guide dog, and applied at Guide Dogs for the Blind in 2010. In January 2011 he began a three-week training session with his new guide dog, Desilu, nicknamed Desi. He graduated from the program on February 12, 2011. He said, "They worked us 14 hours a day, until we were almost as smart as our dogs."[28]


Aronson has written more than twenty books, including textbooks, popularizations and one book of children's fiction with his granddaughter Ruth Aronson. In 2010, Psychology Press published a book of essays and scholarly articles by his friends, colleagues, and former students celebrating his influence on their work: The Scientist and the Humanist: A Festschrift in Honor of Elliot Aronson.
