Israel is not merely a geographic backdrop in Daniel Kahneman’s account; it is the institutional and historical setting in which his psychology repeatedly meets consequential decisions. The country appears first as a young state whose unfinished institutions gave an inexperienced psychologist extraordinary responsibility, and later as a society in which war, terrorism, military selection, and public policy made the limits of intuition visible. Israel therefore links personal biography to a broader inquiry into how people interpret uncertainty and act under pressure.

A Young State and a Young Psychologist

In 1955, Israel was only seven years old, and its institutions were still being built. That condition helps explain why a twenty-one-year-old lieutenant in the Israeli Defense Forces could be assigned responsibility for establishing an interview system for the entire army. Kahneman’s bachelor’s degree in psychology apparently made him the best-trained psychologist available, even though his direct supervisor was a brilliant researcher with a degree in chemistry. The episode presents Israel as a state whose urgent administrative needs temporarily overrode ordinary expectations of professional seniority.

The army already administered psychometric tests to every drafted soldier and interviewed recruits being considered for combat duty. Young draftees, most of them women exempt from combat service at the time, received several weeks of training before conducting fifteen- to twenty-minute interviews. Their task was to form a general impression of each recruit’s personality, estimate general fitness for combat, and recommend a suitable branch such as infantry, artillery, or armor. Follow-up evaluations had shown that the procedure was almost useless at predicting later success, yet Kahneman was ordered to devise a more useful interview without increasing its duration. Israel thus supplied the practical problem that led him toward a lasting concern with the validity of professional judgment.

War and the Misreading of Randomness

The Yom Kippur War brought Kahneman into another Israeli setting where intuitive explanations threatened to produce harmful action. The Israeli air war initially went badly because Egyptian ground-to-air missiles performed unexpectedly well. Losses were high and seemed unevenly distributed: of two squadrons flying from the same base, one had lost four planes while the other had lost none. Military leaders began an inquiry to discover what the unsuccessful squadron was doing wrong, but there was no prior reason to believe that one squadron was more effective than the other, and investigators found no operational difference.

Kahneman advised senior officers in the Israeli Air Force to stop the investigation. The pilots’ outcomes could have been shaped by random differences, including how often they went home between missions and details of debriefings. In his view, luck was the most likely explanation, while a search for an obscure cause would have been unlikely to succeed. Continuing the inquiry also imposed a moral burden: pilots in the squadron that suffered losses might be made to feel responsible for their own deaths and for the deaths of their friends. Israel’s wartime experience therefore became a concrete demonstration of regression toward the mean and of the human tendency to turn uneven random outcomes into stories of skill or failure.

Terrorism, Buses, and the Experience of Risk

Israel later provided a setting for Kahneman’s account of the possibility effect and the emotional force of rare events. During visits to the country, he encountered a period when suicide bombings on buses were relatively common in public discussion, though rare in absolute terms. Between December 2001 and September 2004, there were twenty-three bombings and 236 fatalities, while approximately 1.3 million people rode buses each day. The numerical risk to any individual traveler was tiny, but the public did not experience it as tiny. People avoided buses whenever possible, and passengers scanned fellow travelers for packages or bulky clothing that might conceal a bomb.

Kahneman discovered that knowing the statistics did not make him immune. Driving a rented car, he disliked stopping next to a bus at a red light and drove away more quickly when the light changed. He recognized that a driving accident was more likely to injure him than a bomb near a bus, yet the sight of the bus activated an unpleasant image and an impulse to escape it. His conduct was not governed by a proportionate calculation of survival; it was shaped by the immediate wish to stop thinking about bombs.

This Israeli experience illustrates how terrorism produces an availability cascade. Vivid images of death, reinforced by media attention and conversation, become associated with a particular situation, such as standing beside a bus. The resulting emotional arousal is automatic and difficult to control. System 2 may know that the probability is negligible, but that knowledge does not remove the discomfort generated by System 1. The response is also relatively insensitive to the exact size of the probability: a risk reduced from two possible bombers to one may be halved mathematically without making residents feel half as safe.

Israel as a Laboratory of Judgment and Policy

Israel’s importance in the book extends beyond military and terrorist threat. The country is also the setting of Daniel Kahneman–Amos Tversky collaboration and of a wider intellectual culture in which competing approaches to decision making could be tested against real professional practice. Kahneman contrasts his own early formation, shaped by the illusion of validity and Paul Meehl’s demonstrations of the weakness of clinical prediction, with Gary Klein’s experience studying fireground commanders. The resulting Daniel Kahneman–Gary Klein adversarial collaboration asked when an experienced professional’s intuition could be trusted rather than assuming that intuition was either uniformly defective or automatically wise.

Their conclusion gives Israel’s institutional settings a broader significance. Intuition is more likely to be valid when the environment is sufficiently regular to be predictable and when the decision maker has had prolonged opportunity to learn its regularities. Confidence alone is not evidence of validity, because cognitive ease and coherence can create a compelling but false story. Israel’s army, its wartime operations, and its public response to terrorism repeatedly show why the provenance of a judgment matters: a familiar and emotionally vivid situation may generate confidence without supplying reliable cues.

Israel also becomes part of the policy history associated with behavioral economics. Research on framing and defaults showed that choices can change dramatically when the form of a decision changes. In organ donation, neighboring countries with similar cultures displayed radically different donation rates: Austria approached 100 percent while Germany stood at 12 percent; Sweden reached 86 percent while Denmark reached only 4 percent. The decisive difference was whether donation was the default, requiring people to opt out, or required an affirmative opt-in. The comparison supports the broader claim that Humans often fail to deliberate over important choices and that institutional design can guide behavior without eliminating freedom.

Across these episodes, Israel is rendered as a place where unfinished institutions, military danger, public fear, and experimental intelligence converge. It gives Kahneman’s theories their biographical origin and their ethical pressure. The country’s episodes do not prove that intuition is worthless; rather, they expose the conditions under which it can become either a trained response to regular cues or a confident reaction to randomness, vividness, and fear.
