Daniel Kahneman

Daniel Kahneman (/ˈkɑːnəmən/; Hebrew: דניאל כהנמן; born March 5, 1934) is an Israeli-American psychologist and economist notable for his work on the psychology of judgment and decision-making, as well as behavioral economics, for which he was awarded the 2002 Nobel Memorial Prize in Economic Sciences (shared with Vernon L. Smith). His empirical findings challenge the assumption of human rationality prevailing in modern economic theory.

With Amos Tversky and others, Kahneman established a cognitive basis for common human errors that arise from heuristics and biases, and developed prospect theory.

In 2011 he was named by Foreign Policy magazine in its list of top global thinkers.[2] In the same year his book Thinking, Fast and Slow, which summarizes much of his research, was published and became a best seller.[3] In 2015, The Economist listed him as the seventh most influential economist in the world.[4]

He is professor emeritus of psychology and public affairs at Princeton University's Princeton School of Public and International Affairs. Kahneman is a founding partner of TGG Group, a business and philanthropy consulting company. He was married to cognitive psychologist and Royal Society Fellow Anne Treisman, who died in 2018.[5]

Early life

Daniel Kahneman was born in Tel Aviv, Mandatory Palestine, in 1934, where his mother, Rachel, was visiting relatives. His parents were Lithuanian Jews who had emigrated to France in the early 1920s. He spent his childhood years in Paris. Kahneman and his family were in Paris when it was occupied by Nazi Germany in 1940. His father, Efrayim, was picked up in the first major round-up of French Jews, but he was released after six weeks due to the intervention of his employer, La Cagoule backer Eugène Schueller.[6]: 52  The family was on the run for the remainder of the war, and survived, except for the death of Kahneman's father due to diabetes in 1944. Kahneman and his family then moved to British Mandatory Palestine in 1948, just before the creation of the state of Israel.[5]

Kahneman has written of his experience in Nazi-occupied France, explaining in part why he entered the field of psychology:

It must have been late 1941 or early 1942. Jews were required to wear the Star of David and to obey a 6 p.m. curfew. I had gone to play with a Christian friend and had stayed too late. I turned my brown sweater inside out to walk the few blocks home. As I was walking down an empty street, I saw a German soldier approaching. He was wearing the black uniform that I had been told to fear more than others – the one worn by specially recruited SS soldiers. As I came closer to him, trying to walk fast, I noticed that he was looking at me intently. Then he beckoned me over, picked me up, and hugged me. I was terrified that he would notice the star inside my sweater. He was speaking to me with great emotion, in German. When he put me down, he opened his wallet, showed me a picture of a boy, and gave me some money. I went home more certain than ever that my mother was right: people were endlessly complicated and interesting.

— [5]

Israeli intellectual Yeshayahu Leibowitz, whom Kahneman describes as influential in his intellectual development, was Kahneman's chemistry teacher at Beit-Hakerem High School, and Kahneman's physiology professor at university.[7]

Kahneman's paternal uncle was Rabbi Yosef Shlomo Kahaneman, the head of the Ponevezh Yeshiva.[7]

Education and early career

In 1954 Kahneman received his Bachelor of Science degree, with a major in psychology and a minor in mathematics, from the Hebrew University of Jerusalem.

He served in the psychology department of the Israeli Defense Forces, and as an infantryman. One of his responsibilities was to evaluate candidates for officer's training school, and to develop tests and measures for this purpose. Kahneman describes his military service as a "very important period" in his life.[7]

In 1958 he went to the United States to study for his PhD in Psychology at the University of California, Berkeley. His 1961 dissertation, advised by Susan Ervin, examined relations between adjectives in the semantic differential and allowed him to "engage in two of [his] favorite pursuits: the analysis of complex correlational structures and FORTRAN programming."[5]

Academic career

Cognitive psychology

Kahneman began his academic career as a lecturer in psychology at the Hebrew University of Jerusalem in 1961.[5] He was promoted to senior lecturer in 1966. His early work focused on visual perception and attention. For example, his first publication in the prestigious journal Science was entitled "Pupil Diameter and Load on Memory" (Kahneman & Beatty, 1966). During this period, Kahneman was a visiting scientist at the University of Michigan (1965–66) and the Applied Psychology Research Unit in Cambridge (1968/1969, summers). He was a fellow at the Center for Cognitive Studies, and a lecturer in cognitive psychology at Harvard University in 1966/1967.

Judgment and decision-making

This period marks the beginning of Kahneman's lengthy collaboration with Amos Tversky. Together, Kahneman and Tversky published a series of seminal articles in the general field of judgment and decision-making, culminating in the publication of their prospect theory in 1979 (Kahneman & Tversky, 1979). Following this, the pair teamed with Paul Slovic to edit a compilation entitled "Judgement Under Uncertainty: Heuristics and Biases" (1982) that proved to be an important summary of their work and of other recent advances that had influenced their thinking. Kahneman was ultimately awarded the Nobel Memorial Prize in Economics in 2002 for his work on prospect theory.

In his Nobel biography Kahneman states that his collaboration with Tversky began after Kahneman had invited Tversky to give a guest lecture to one of Kahneman's seminars at Hebrew University in 1968 or 1969.[5] Their first jointly written paper, "Belief in the Law of Small Numbers," was published in 1971 (Tversky & Kahneman, 1971). They published seven articles in peer-reviewed journals in the years 1971–1979. Aside from "Prospect Theory," the most important of these articles was "Judgment Under Uncertainty: Heuristics and Biases" (Tversky & Kahneman, 1974), which was published in the prestigious journal Science and introduced the notion of anchoring. Kahneman wrote the paper at the Van Leer Jerusalem Institute.[7]

Kahneman left Hebrew University in 1978 to take a position at the University of British Columbia.[5]

In 2021, Kahneman and co-authors Olivier Sibony and Cass Sunstein contributed to the field with work on unwanted variability in human judgments of the same problem, what they term 'noise'. In Noise: A Flaw in Human Judgment, they write that due to factors such as cognitive biases, group dynamics, mood, stress, fatigue, and differences in skill between assessors/decision makers/judges, judgements that should ideally be identical in fact often differ a lot. This gives rise to injustices, hazards and costs of various types. Furthermore, it does so in a way that is distinct from statistical bias and which is affected by cognitive biases but not limited to their influence. In the book, which received much press, they explain what noise is, how it can be detected and how it can be reduced – which can also reduce bias.

Behavioral economics

Kahneman and Tversky were both fellows at the Center for Advanced Study in the Behavioral Sciences at Stanford University in the academic year 1977–1978. A young economist named Richard Thaler was a visiting professor at the Stanford branch of the National Bureau of Economic Research during that same year. According to Kahneman, "[Thaler and I] soon became friends, and have ever since had a considerable influence on each other's thinking."[5] Building on prospect theory and Kahneman and Tversky's body of work, Thaler published "Toward a Positive Theory of Consumer Choice" in 1980, a paper which Kahneman has called "the founding text of behavioral economics."[5]

Kahneman and Tversky became heavily involved in the development of this new approach to economic theory, and their involvement in this movement had the effect of reducing the intensity and exclusivity of their earlier period of joint collaboration.[citation needed] According to Kahneman the collaboration 'tapered off' in the early 1980s, although they tried to revive it.[8] Factors included Tversky receiving most of the external credit for the output of the partnership, and a reduction in the generosity with which Tversky and Kahneman interacted with each other.[9] They would continue to publish together until the end of Tversky's life, but the period when Kahneman published almost exclusively with Tversky ended in 1983, when he published two papers with Anne Treisman, his wife since 1978.

Hedonic psychology

In the 1990s, Kahneman's research focus began to gradually shift in emphasis towards hedonic psychology. According to Kahneman and colleagues,

Hedonic psychology...is the study of what makes experiences and life pleasant or unpleasant. It is concerned with feelings of pleasure and pain, of interest and boredom, of joy and sorrow, and of satisfaction and dissatisfaction. It is also concerned with the whole range of circumstances, from the biological to the societal, that occasion suffering and enjoyment.[10]

(This subfield is closely related to the positive psychology movement, which was steadily gaining in popularity at the time.)

It is difficult to determine precisely when Kahneman's research began to focus on hedonics, although it likely stemmed from his work on the economic notion of utility. After publishing multiple articles and chapters in all but one of the years spanning the period 1979–1986 (for a total of 23 published works in 8 years), Kahneman published exactly one chapter during the years 1987–1989. After this hiatus, articles on utility and the psychology of utility began to appear (e.g., Kahneman & Snell, 1990; Kahneman & Thaler, 1991; Kahneman & Varey, 1991).

In 1992 Varey and Kahneman introduced the method of evaluating moments and episodes as a way to capture "experiences extended across time". While Kahneman continued to study decision-making (e.g., Kahneman, 1992, 1994; Kahneman & Lovallo, 1993), hedonic psychology was the focus of an increasing number of publications (e.g., Fredrickson & Kahneman, 1993; Kahneman, Fredrickson, Schreiber & Redelemeier, 1993; Kahneman, Wakker & Sarin, 1997; Redelmeier & Kahneman, 1996), culminating in a volume co-edited with Ed Diener and Norbert Schwarz, scholars of affect and well-being.[11]

Focusing illusion

With David Schkade, Kahneman developed the notion of the focusing illusion (Kahneman & Schkade, 1998; Kahneman, Krueger, Schkade, Schwarz & Stone, 2006) to explain in part the mistakes people make when estimating the effects of different scenarios on their future happiness (also known as affective forecasting, which has been studied extensively by Daniel Gilbert). The "illusion" occurs when people consider the impact of one specific factor on their overall happiness, they tend to greatly exaggerate the importance of that factor, while overlooking the numerous other factors that would in most cases have a greater impact.

A good example is provided by Kahneman and Schkade's 1998 paper "Does living in California make people happy? A focusing illusion in judgments of life satisfaction".[12] In that paper, students in the Midwest and in California reported similar levels of life satisfaction, but the Midwesterners thought their Californian peers would be happier. The only distinguishing information the Midwestern students had when making these judgments was the fact that their hypothetical peers lived in California. Thus, they "focused" on this distinction, thereby overestimating the effect of the weather in California on its residents' satisfaction with life.

Peak–end rule and remembered pleasure

One of the cognitive biases in hedonic psychology discovered by Kahneman is called the peak–end rule. It affects how we remember the pleasantness or unpleasantness of experiences. It states that our overall impression of past events is determined for the most part not by the total pleasure and suffering it contained but by how it felt at its peaks and at its end.[13] For example, the memory of a painful colonoscopy is improved if the examination is extended by three minutes in which the scope is still inside but not moved anymore, resulting in a moderately uncomfortable sensation. This extended colonoscopy, despite involving more pain overall, is remembered less negatively due to the reduced pain at the end. This even increases the likelihood for the patient to return for subsequent procedures.[14] Kahneman explains this distortion in terms of the difference between two selves: the experiencing self, which is aware of pleasure and pain as they are happening, and the remembering self, which shows the aggregate pleasure and pain over an extended period of time. The distortions due to the peak–end rule happen on the level of the remembering self. Our tendency to rely on the remembering self can often lead us to pursue courses of action that are not in our best self-interest.[15][16][17][18]

Happiness and life satisfaction

Kahneman has defined happiness as "what I experience here and now",[19] but says that in reality humans pursue life satisfaction,[20] which "is connected to a large degree to social yardsticks–achieving goals, meeting expectations."[21][22][23]

Teaching

Kahneman is a senior scholar and faculty member emeritus at Princeton University's Department of Psychology and Princeton School of Public and International Affairs. He is also a fellow at Hebrew University and a Gallup Senior Scientist.[24]

Personal life

Kahneman's first wife was Irah Kahneman,[25] an Israeli educational psychologist, with whom he had two children. His son has schizophrenia, and his daughter works in technology.[26]

His second wife was the cognitive psychologist Anne Treisman, from 1978 until her death in 2018. As of 2014, they lived part-time in Berkeley, California.[27][28] As of 2022, he lives in New York City with Barbara Tversky, the widow of his long-time collaborator Amos Tversky.[29][7]

In 2015 Kahneman described himself as a very hard worker, as "a worrier" and "not a jolly person." But, despite this, he said, "I'm quite capable of great enjoyment, and I've had a great life."[30]

first publication in the prestigious journal Science was entitled Pupil Diameter and Load on Memory Kahneman amp Beatty 1966 During this period Kahneman was a visiting scientist at the University of Michigan 1965 66 and the Applied Psychology Research Unit in Cambridge 1968 1969 summers He was a fellow at the Center for Cognitive Studies and a lecturer in cognitive psychology at Harvard University in 1966 1967 Judgment and decision making Edit This period marks the beginning of Kahneman s lengthy collaboration with Amos Tversky Together Kahneman and Tversky published a series of seminal articles in the general field of judgment and decision making culminating in the publication of their prospect theory in 1979 Kahneman amp Tversky 1979 Following this the pair teamed with Paul Slovic to edit a compilation entitled Judgement Under Uncertainty Heuristics and Biases 1982 that proved to be an important summary of their work and of other recent advances that had influenced their thinking Kahneman was ultimately awarded the Nobel Memorial Prize in Economics in 2002 for his work on prospect theory In his Nobel biography Kahneman states that his collaboration with Tversky began after Kahneman had invited Tversky to give a guest lecture to one of Kahneman s seminars at Hebrew University in 1968 or 1969 5 Their first jointly written paper Belief in the Law of Small Numbers was published in 1971 Tversky amp Kahneman 1971 They published seven articles in peer reviewed journals in the years 1971 1979 Aside from Prospect Theory the most important of these articles was Judgment Under Uncertainty Heuristics and Biases Tversky amp Kahneman 1974 which was published in the prestigious journal Science and introduced the notion of anchoring Kahneman wrote the paper at the Van Leer Jerusalem Institute 7 Kahneman left Hebrew University in 1978 to take a position at the University of British Columbia 5 In 2021 Kahneman and co authors Olivier Sibony and Cass Sunstein contributed to the field with work on unwanted variability in human judgments of the same problem what they term noise In Noise A Flaw in Human Judgment they write that due to factors such as cognitive biases group dynamics mood stress fatigue and differences in skill between assessors decision makers judges judgements that should ideally be identical in fact often differ a lot This gives rise to injustices hazards and costs of various types Furthermore it does so in a way that is distinct from statistical bias and which is affected by cognitive biases but not limited to their influence In the book which received much press they explain what noise is how it can be detected and how it can be reduced which can also reduce bias Behavioral economics Edit Kahneman and Tversky were both fellows at the Center for Advanced Study in the Behavioral Sciences at Stanford University in the academic year 1977 1978 A young economist named Richard Thaler was a visiting professor at the Stanford branch of the National Bureau of Economic Research during that same year According to Kahneman Thaler and I soon became friends and have ever since had a considerable influence on each other s thinking 5 Building on prospect theory and Kahneman and Tversky s body of work Thaler published Toward a Positive Theory of Consumer Choice in 1980 a paper which Kahneman has called the founding text of behavioral economics 5 Kahneman and Tversky became heavily involved in the development of this new approach to economic theory and their involvement in this movement had the effect of reducing the intensity and exclusivity of their earlier period of joint collaboration citation needed According to Kahneman the collaboration tapered off in the early 1980s although they tried to revive it 8 Factors included Tversky receiving most of the external credit for the output of the partnership and a reduction in the generosity with which Tversky and Kahneman interacted with each other 9 They would continue to publish together until the end of Tversky s life but the period when Kahneman published almost exclusively with Tversky ended in 1983 when he published two papers with Anne Treisman his wife since 1978 Hedonic psychology Edit In the 1990s Kahneman s research focus began to gradually shift in emphasis towards hedonic psychology According to Kahneman and colleagues Hedonic psychology is the study of what makes experiences and life pleasant or unpleasant It is concerned with feelings of pleasure and pain of interest and boredom of joy and sorrow and of satisfaction and dissatisfaction It is also concerned with the whole range of circumstances from the biological to the societal that occasion suffering and enjoyment 10 This subfield is closely related to the positive psychology movement which was steadily gaining in popularity at the time It is difficult to determine precisely when Kahneman s research began to focus on hedonics although it likely stemmed from his work on the economic notion of utility After publishing multiple articles and chapters in all but one of the years spanning the period 1979 1986 for a total of 23 published works in 8 years Kahneman published exactly one chapter during the years 1987 1989 After this hiatus articles on utility and the psychology of utility began to appear e g Kahneman amp Snell 1990 Kahneman amp Thaler 1991 Kahneman amp Varey 1991 In 1992 Varey and Kahneman introduced the method of evaluating moments and episodes as a way to capture experiences extended across time While Kahneman continued to study decision making e g Kahneman 1992 1994 Kahneman amp Lovallo 1993 hedonic psychology was the focus of an increasing number of publications e g Fredrickson amp Kahneman 1993 Kahneman Fredrickson Schreiber amp Redelemeier 1993 Kahneman Wakker amp Sarin 1997 Redelmeier amp Kahneman 1996 culminating in a volume co edited with Ed Diener and Norbert Schwarz scholars of affect and well being 11 Focusing illusion Edit With David Schkade Kahneman developed the notion of the focusing illusion Kahneman amp Schkade 1998 Kahneman Krueger Schkade Schwarz amp Stone 2006 to explain in part the mistakes people make when estimating the effects of different scenarios on their future happiness also known as affective forecasting which has been studied extensively by Daniel Gilbert The illusion occurs when people consider the impact of one specific factor on their overall happiness they tend to greatly exaggerate the importance of that factor while overlooking the numerous other factors that would in most cases have a greater impact A good example is provided by Kahneman and Schkade s 1998 paper Does living in California make people happy A focusing illusion in judgments of life satisfaction 12 In that paper students in the Midwest and in California reported similar levels of life satisfaction but the Midwesterners thought their Californian peers would be happier The only distinguishing information the Midwestern students had when making these judgments was the fact that their hypothetical peers lived in California Thus they focused on this distinction thereby overestimating the effect of the weather in California on its residents satisfaction with life Peak end rule and remembered pleasure Edit One of the cognitive biases in hedonic psychology discovered by Kahneman is called the peak end rule It affects how we remember the pleasantness or unpleasantness of experiences It states that our overall impression of past events is determined for the most part not by the total pleasure and suffering it contained but by how it felt at its peaks and at its end 13 For example the memory of a painful colonoscopy is improved if the examination is extended by three minutes in which the scope is still inside but not moved anymore resulting in a moderately uncomfortable sensation This extended colonoscopy despite involving more pain overall is remembered less negatively due to the reduced pain at the end This even increases the likelihood for the patient to return for subsequent procedures 14 Kahneman explains this distortion in terms of the difference between two selves the experiencing self which is aware of pleasure and pain as they are happening and the remembering self which shows the aggregate pleasure and pain over an extended period of time The distortions due to the peak end rule happen on the level of the remembering self Our tendency to rely on the remembering self can often lead us to pursue courses of action that are not in our best self interest 15 16 17 18 Happiness and life satisfaction Edit Kahneman has defined happiness as what I experience here and now 19 but says that in reality humans pursue life satisfaction 20 which is connected to a large degree to social yardsticks achieving goals meeting expectations 21 22 23 Teaching Edit Kahneman is a senior scholar and faculty member emeritus at Princeton University s Department of Psychology and Princeton School of Public and International Affairs He is also a fellow at Hebrew University and a Gallup Senior Scientist 24 Personal life EditKahneman s first wife was Irah Kahneman 25 an Israeli educational psychologist with whom he had two children His son has schizophrenia and his daughter works in technology 26 His second wife was the cognitive psychologist Anne Treisman from 1978 until her death in 2018 As of 2014 they lived part time in Berkeley California 27 28 As of 2022 he lives in New York City with Barbara Tversky the widow of his long time collaborator Amos Tversky 29 7 In 2015 Kahneman described himself as a very hard worker as a worrier and not a jolly person But despite this he said I m quite capable of great enjoyment and I ve had a great life 30 Awards and recognition EditIn 2001 he was elected a member of the National Academy of Sciences 31 In 2002 Kahneman received the Nobel Memorial Prize in Economic Sciences despite being a research psychologist for his work in prospect theory Kahneman states he has never taken a single economics course that everything that he knows of the subject he and Tversky learned from their collaborators Richard Thaler and Jack Knetsch Kahneman co recipient with Tversky earned the 2003 University of Louisville Grawemeyer Award for Psychology 32 In 2005 he was elected a member of the American Philosophical Society 33 In 2007

of Economics at Erasmus University in Rotterdam Netherlands In his acceptance speech Kahneman said when you live long enough you see the impossible become reality He was referring to the fact that he would never have expected to be honored as an economist when he started his studies into what would become Behavioral Economics 35 In both 2011 and 2012 he made the Bloomberg 50 most influential people in global finance 36 On November 9 2011 he was awarded the Talcott Parsons Prize by the American Academy of Arts and Sciences 37 His book Thinking Fast and Slow was the winner of the 2011 Los
