The Undoing Project

The Undoing Project: A Friendship That Changed Our Minds is a 2016 non-fiction book by American author Michael Lewis, published by W. W. Norton & Company, that chronicles the groundbreaking collaboration between Israeli-American psychologists Daniel Kahneman and Amos Tversky.^[1] The narrative centers on their friendship and joint research, which challenged traditional economic theories by revealing systematic flaws in human judgment and decision-making, ultimately founding the field of behavioral economics.^[2] Their work, beginning in 1969 at the Hebrew University of Jerusalem, demonstrated how cognitive biases—such as the halo effect, representativeness heuristic, and hindsight bias—influence reasoning, using experiments like the "Linda the feminist bank teller" scenario to show how stereotypes override probabilistic thinking.^[3]^[2] Lewis portrays the duo's partnership as an intense intellectual symbiosis, marked by shared authorship on papers typed alternately at a single typewriter and a dynamic interplay of Tversky's charisma and Kahneman's introspective depth, often described as "sharing a mind."^[2] Their studies debunked myths like the "hot hand" in basketball and applied concepts such as regression to the mean to real-world scenarios, including Israeli Air Force pilot training.^[3] Despite their profound bond, the book also explores tensions that arose, including professional rivalries and personal strains, culminating in Kahneman receiving the Nobel Prize in Economic Sciences in 2002 for their prospect theory, while Tversky, who died in 1996, was posthumously recognized.^[1]^[3] The book's themes extend to broader implications of their research, influencing fields like evidence-based medicine, government policy, Big Data analysis, and even Lewis's own earlier works such as Moneyball.^[1] By "undoing" assumptions of human rationality, Kahneman and Tversky's insights have reshaped understandings of uncertainty, expert overconfidence, and everyday choices, from retirement savings to cellphone usage habits.^[2]^[3]

Background

Daniel Kahneman

Daniel Kahneman was born on March 5, 1934, in Tel Aviv, Mandatory Palestine, during a visit by his mother to relatives; his parents, who were of Lithuanian Jewish descent, were living in France at the time.^[4] The family soon relocated to Paris, where Kahneman spent his early childhood amid a culturally rich but precarious environment. His father worked as the chief of research in a large chemical factory, fostering an intellectually stimulating home. However, the Nazi occupation of Paris in 1940 upended their lives; Kahneman's father was arrested in 1942 but released after intervention, leading the family to hide for the remainder of World War II. Experiences of antisemitism, including a traumatic encounter where a stranger, upon seeing his yellow star, offered him money for candy—which terrified his mother—ignited his fascination with human behavior and its unpredictability.^[4]^[5] Tragically, his father succumbed to diabetes complications in 1944, just weeks before the city's liberation, leaving a lasting impact on the young Kahneman.^[4] Following the war, Kahneman's mother reunited the family remnants and emigrated to the newly established State of Israel in 1948, where he joined her at age 14. He enrolled at the Hebrew University of Jerusalem, completing a BSc in psychology with a minor in mathematics in 1954 after an accelerated two-year program. Demonstrating early academic promise despite self-described mediocrity in mathematics, after military service he spent a year in Oxford as a research assistant to Richard Gregory before returning to Jerusalem and pursuing graduate studies in the US.^[4] Kahneman's mandatory military service in the Israeli Defense Forces spanned 1954 to 1956, beginning with a year as a second lieutenant leading an infantry platoon before his transfer to the Psychology Branch. There, at age 21, he contributed to developing structured interview protocols and assessment methods for selecting and training officers, drawing on his nascent psychological expertise to evaluate traits like leadership potential and sociability. This practical experience honed his analytical approach to human judgment. He then obtained a PhD in psychology from the University of California, Berkeley, in 1961, with a dissertation on an analytical model of the semantic differential—a tool for measuring emotional connotations of words. Returning to Hebrew University as a lecturer that year, Kahneman initially concentrated his research on sensory perception, particularly visual attention and pupil dilation as indicators of cognitive effort. By the late 1960s, however, his focus evolved toward the psychological processes underlying judgment under uncertainty.^[4]^[6]^[7] Often characterized as introspective and prone to self-doubt—qualities rooted in his wartime isolation and intellectual humility—Kahneman's personality contrasted with more assertive contemporaries, enabling profound empathy for cognitive flaws in decision-making. These traits profoundly influenced his emerging insights into human psychology. In 1969, during a graduate seminar at the Hebrew University of Jerusalem, he invited Amos Tversky to guest lecture, marking the start of their influential partnership.^[4]^[6]^[8]

Amos Tversky

Amos Tversky was born on March 16, 1937, in Haifa, Mandatory Palestine (now Israel), to parents who had emigrated from Eastern Europe. His father, Yosef Tversky, was a veterinarian, while his mother, Jenia Tversky, worked as a social worker and served as a member of the Knesset for Mapai in 1951–1955, 1959–1961, and 1963 until her death in 1964.^[9] Growing up in a family with strong Zionist roots, Tversky developed an early interest in intellectual pursuits, influenced by his parents' professional and political engagements.^[10] Following high school, Tversky served in the Israel Defense Forces from 1954 to 1956, enlisting in the Paratroopers Brigade where he participated in combat operations during the 1956 Suez Crisis.^[11] His military service was distinguished; he rose to the rank of captain and received decorations for bravery, experiences that cultivated his leadership qualities and comfort with risk-taking.^[9] Tversky pursued higher education at the Hebrew University of Jerusalem, earning a Bachelor of Science in psychology in 1961.^[9] He then moved to the United States for graduate studies, completing a PhD in psychology at the University of Michigan in 1965; his dissertation, supervised by Clyde Coombs, focused on signal detection theory within the framework of mathematical psychology. After briefly teaching at Michigan, he returned to Israel in 1965 and joined the faculty at Hebrew University, where he began his academic career with research on decision-making under risk and foundational aspects of mathematical psychology, including measurement theory and utility models.^[9]^[10]^[12] Known for his charismatic and quick-witted personality, Tversky was often described as the more outgoing and assertive partner in intellectual collaborations, bringing a focus on rigorous quantitative modeling to his work.^[8] Athletic and broad-shouldered, he excelled in sports like basketball, reflecting a dynamic energy that complemented more introspective colleagues in Israel's vibrant academic scene.^[8]

The Collaboration

Meeting and early partnership

Daniel Kahneman and Amos Tversky first encountered each other meaningfully in the spring of 1969 at Hebrew University of Jerusalem, where Kahneman had invited Tversky to deliver a guest lecture in his graduate seminar titled "Applications of Psychology," focused on real-world problems including decision-making.^[4] Following the lecture, the two continued their discussion, including over lunches, where they bonded over shared experiences in the Israel Defense Forces—Kahneman through psychological research on officer selection and training, and Tversky as a paratrooper—and their mutual fascination with human judgment flaws.^[13] This interaction ignited an intellectual spark, as Kahneman challenged Tversky's presentation on intuitive judgments, highlighting inconsistencies between intuition and rational models, which aligned with their emerging shared research interests in cognitive biases.^[14] Their formal collaboration began in 1970, when they started delivering joint lectures and designing experiments together at Hebrew University, merging Kahneman's clinically derived insights into perceptual and cognitive errors with Tversky's rigorous mathematical modeling of probabilistic reasoning.^[4] This partnership quickly evolved into a deep personal friendship, marked by daily, hours-long conversations that dissected ideas with extraordinary intensity, periods of cohabitation during academic travels to places like Eugene, Oregon, and a profound reciprocal influence that reshaped each man's intellectual framework.^[13] The duo's early collaboration culminated in their first joint publication in 1971, titled "Belief in the Law of Small Numbers," which exposed systematic errors in the intuitive statistical judgments of trained researchers and psychologists, signaling the onset of their groundbreaking body of work.^[15]

Key discoveries in cognitive psychology

Kahneman and Tversky's joint research revolutionized the understanding of judgment and decision-making by identifying cognitive heuristics that lead to systematic biases under uncertainty. In their landmark 1974 paper "Judgment under Uncertainty: Heuristics and Biases," published in Science, they outlined three primary heuristics: representativeness, availability, and anchoring and adjustment. These mental shortcuts, while efficient, often produce predictable errors in probabilistic reasoning, diverging from normative statistical models.^[16] The representativeness heuristic involves evaluating the probability of an event or category by how closely it resembles a prototype or stereotype, frequently ignoring base-rate information. For instance, individuals might assess a reserved and meticulous person's likelihood of being a librarian as higher than that of a salesperson, despite salespeople vastly outnumbering librarians in the population, leading to biases like base-rate neglect and misconceptions of chance.^[17]^[16] The availability heuristic bases probability estimates on the ease with which relevant instances can be retrieved from memory, causing overestimation of salient or emotionally charged events. An example is judging the frequency of causes of death, such as underestimating risks like diabetes while overestimating dramatic ones like floods, due to media coverage and recency effects.^[17]^[16] Anchoring and adjustment occurs when people form estimates by starting from an arbitrary initial value and making insufficient adjustments, resulting in estimates biased toward the anchor. In one experiment, participants estimating the percentage of African countries in the United Nations adjusted from a randomly spun wheel value (e.g., 10 or 65), producing medians of 25 and 45, respectively, demonstrating how irrelevant anchors skew judgments.^[17]^[16] This 1974 work established that intuitive judgments deviate systematically from rational benchmarks, laying the groundwork for behavioral insights into human error. It has been cited over 50,000 times, influencing cognitive psychology by shifting focus from error-free rationality to bounded cognition.^[16]^[18] Advancing their framework, Kahneman and Tversky introduced prospect theory in their 1979 Econometrica paper "Prospect Theory: An Analysis of Decision under Risk," which models choices under risk more descriptively than expected utility theory. Unlike expected utility's focus on final wealth states, prospect theory evaluates outcomes as gains or losses relative to a neutral reference point, capturing real-world risk attitudes.^[19] Central to prospect theory is the value function, which is concave for gains—reflecting risk aversion—and convex for losses—indicating risk-seeking behavior—with a steeper slope for losses, embodying loss aversion where the pain of losses exceeds the pleasure of equivalent gains. Reference dependence underscores that values depend on perceived changes from the reference, not absolute outcomes, while probability weighting distorts objective probabilities by overweighting low probabilities (e.g., lotteries) and underweighting high ones (e.g., insurance).^[20] These elements explain paradoxes like the Allais paradox, where people reject fair gambles to avoid certain loss, challenging expected utility's linearity in probabilities and utilities.^[20]^[19] Framing effects, further elaborated in their 1981 Science paper "The Framing of Decisions and the Psychology of Choice," illustrate how the presentation of equivalent options influences preferences, violating invariance principles of rational choice. In the classic Asian disease problem, participants faced a hypothetical outbreak expected to kill 600 people; when framed positively as "saving 200 lives for sure" versus a "1/3 chance to save all 600," 72% chose the certain option, showing risk aversion in gains. Reframed negatively as "400 deaths for sure" versus a "1/3 chance no deaths," 78% opted for the risky choice, exhibiting risk-seeking in losses—despite the programs being mathematically identical. This effect persisted across diverse groups, including physicians, highlighting framing's robustness in medical and policy contexts.^[21] Their discoveries have reshaped multiple disciplines by challenging the rational actor model. In economics, prospect theory and heuristics birthed behavioral economics, integrating psychological biases into models of markets and incentives, as evidenced by Kahneman's 2002 Nobel Prize in Economic Sciences.^[22] In policy, concepts like loss aversion inform "nudge" strategies, such as default options in retirement savings to counter inertia. In medicine, framing effects guide communication of treatment risks, improving patient adherence by emphasizing gains over losses in survival rates.^[23] Overall, their work underscores the need for debiasing tools in high-stakes decisions, influencing regulatory frameworks worldwide.^[22]

Book Content

Narrative structure

Michael Lewis structures The Undoing Project as a character-driven narrative that intertwines the personal biographies of Daniel Kahneman and Amos Tversky with the intellectual drama of their collaboration, employing a non-linear timeline to build suspense around the eventual strains in their partnership. The book opens with a prologue centered on Lewis's own encounter with their psychological insights through the lens of sports analytics, specifically referencing how Daryl Morey, general manager of the Houston Rockets, applied concepts of decision-making biases during an NBA draft, echoing the irrationality themes from Lewis's earlier work Moneyball. This entry point highlights how Kahneman and Tversky's ideas on cognitive errors permeated practical fields like basketball, setting a dramatic tone that underscores human fallibility in high-stakes judgments.^[24] The narrative unfolds through a non-linear progression that alternates between the duo's early lives, their collaborative peaks in the 1970s, and the later tensions that threatened their bond, creating a suspenseful arc often referred to as the "undoing" of their relationship. Chapter progression begins by delving into Kahneman's personal insecurities and outsider status in Israeli academia, contrasting with Tversky's confident insider persona, before shifting to their transformative meeting and joint triumphs in challenging rational economic models. This builds to explorations of the personal and professional costs of their work, incorporating vivid vignettes such as dilemmas faced by hospital patients to illustrate decision-making under uncertainty, all while weaving in flashbacks to formative experiences like Kahneman's wartime childhood and Tversky's military service. Lewis employs a primarily chronological framework from their 1969 encounter to Tversky's 1996 death, punctuated by thematic interludes that humanize the scientists through anecdotes drawn from their lives.^[25]^[26]^[27] Lewis's storytelling style is distinctly narrative-driven, reconstructing dialogues and scenes from extensive interviews conducted over seven years with Kahneman, Tversky's family, and colleagues, which lends an intimate, almost novelistic quality to the biography. This approach blends elements of memoir, as Lewis occasionally reflects on his research process and initial reluctance to write the book at Kahneman's urging, creating a layered text that not only recounts events but also mirrors the psychological themes of intuition and error. The book is divided into two broad parts: the first focusing on their personal collaboration and contrasting personalities, and the second examining key theoretical developments, though the overall structure prioritizes emotional and dramatic flow over strict academic exposition.^[26]^[24]^[27] In the epilogue, Lewis reflects on the enduring nature of their friendship amid the strains of professional jealousy and Tversky's illness, culminating in their reconciliation and Kahneman's eventual Nobel recognition, which ties the personal narrative back to broader insights on human connection and regret. This closing emphasizes the redemptive aspects of their partnership, framing the "undoing" not as a complete rupture but as a poignant counterpoint to the innovative legacy they built together.^[24]^[25]

Central themes and concepts

The Undoing Project explores the theme of intellectual synergy through the unlikely partnership between Daniel Kahneman, characterized by persistent doubt and self-criticism, and Amos Tversky, marked by unshakeable confidence and charisma. Their contrasting personalities—Kahneman's introspective caution complementing Tversky's bold assertiveness—fostered a dynamic collaboration that produced seminal insights into human judgment, transforming abstract psychological research into accessible, revolutionary ideas. However, this synergy also sowed seeds of tension, as professional successes amplified feelings of jealousy, particularly when Tversky received greater recognition, straining their bond over time.^[14]^[28]^[29] A core concept in the book is the prevalence of cognitive illusions, vividly illustrated through the distinction between System 1 and System 2 thinking. System 1 represents fast, intuitive processes that operate automatically and efficiently but are prone to biases, while System 2 involves slower, deliberate reasoning that requires effort and can override intuitive errors. Michael Lewis presents these ideas narratively, drawing on Kahneman and Tversky's experiments to show how everyday decisions often fall prey to these mental shortcuts, humanizing the science of flawed cognition.^[14]^[28] The narrative also delves into the personal cost of genius, portraying the relentless obsession that drove Kahneman and Tversky's achievements at great emotional expense. Tversky's intense work ethic led to chronic overwork, blurring the lines between professional ambition and personal well-being, while Kahneman grappled with profound impostor syndrome, constantly questioning his own intellect despite his contributions. These vulnerabilities underscore the human fragility behind intellectual triumphs, revealing how the pursuit of groundbreaking ideas exacted a toll on their mental health and relationships.^[28]^[14] Central to the book is the undoing of rationality, a direct critique of the "homo economicus" model that assumes individuals make consistently logical, self-interested decisions. Kahneman and Tversky's work demonstrates that real-world choices are heavily influenced by emotions, cognitive biases, and irrational heuristics, challenging economists' idealized view of human behavior and paving the way for behavioral economics. Lewis emphasizes how these findings reveal the gap between theoretical rationality and actual decision-making, driven by subconscious forces rather than pure logic.^[28]^[14] The broader implications of these concepts are brought to life through illustrative stories, such as the "Linda problem," which exemplifies the conjunction fallacy—a bias where people judge a specific, detailed scenario as more probable than a general one. In the vignette, participants rate "Linda is a bank teller and is active in the feminist movement" as more likely than "Linda is a bank teller," despite the former being a subset of the latter, highlighting how narrative coherence overrides probabilistic logic. This example, drawn from Kahneman and Tversky's research, serves to humanize abstract cognitive errors, showing their everyday relevance in judgment and decision-making.^[14]^[28]

Writing and Publication

Michael Lewis's involvement

Michael Lewis first encountered the profound influence of Daniel Kahneman and Amos Tversky through a series of interviews conducted for a 2011 Vanity Fair profile on Kahneman, where he discussed the psychologist's upcoming book Thinking, Fast and Slow and the groundbreaking collaborative research with Tversky on cognitive biases and decision-making heuristics.^[30] This interaction highlighted how their work on human irrationality had permeated fields like finance and sports analytics, resonating with themes in Lewis's prior books such as Moneyball (2003), which explored exploiting inefficiencies in baseball scouting, and The Big Short (2010), which examined overlooked risks in financial markets.^[31] Lewis's fascination grew from seeing Kahneman and Tversky as intellectual underdogs who upended rational actor assumptions in economics, much like the protagonists in his narratives who capitalized on systemic flaws.^[32] The concept for The Undoing Project emerged as Lewis traced the roots of statistical revolutions in sports back to Kahneman and Tversky's behavioral insights, connecting to themes in Moneyball.^[31] For the book, Lewis immersed himself in an intensive research process, conducting extensive interviews with Kahneman over multiple sessions that included joint travels to Israel, where they visited key locations from the psychologists' early careers, such as an Israeli army base tied to their formative experiences.^[33] He also drew on conversations with Tversky's family—Lewis had previously taught Tversky's son Oren at the University of California, Berkeley—and accessed personal correspondences and unpublished materials to reconstruct their partnership.^[32] Throughout, Lewis collaborated closely with Kahneman to verify details, ensuring the narrative aligned with historical accuracy while capturing the emotional depth of their collaboration.^[33] Lewis drafted the manuscript amid his family life in Berkeley, California, where he has long resided and where many of the interviews took place, allowing him to interweave personal reflections on underdogs and inefficiencies into the story.^[30] This enabled Lewis to frame the book as an extension of his ongoing exploration of how overlooked human elements drive transformative change in competitive arenas.^[31]

Reception

Critical reviews

The Undoing Project received widespread critical acclaim for its engaging narrative style and ability to humanize complex psychological concepts. In a 2016 review, The New York Times praised the book for blending intellectual rigor with vivid portraiture, noting that it effectively illuminates the groundbreaking work of Amos Tversky and Daniel Kahneman while evoking emotional responses from readers.^[38] Similarly, The New Yorker highlighted the book's portrayal of the duo's friendship, describing it as captivating and rich in emotional depth, which brought their intellectual partnership to life for a general audience.^[14] Critics specifically commended Michael Lewis's skill in making scientific ideas accessible without sacrificing substance. The Pittsburgh Post-Gazette described the book as potentially Lewis's finest work, lauding his mastery of nonfiction narrative in weaving together biography and intellectual history.^[39] Kirkus Reviews echoed this, calling Lewis's prose engaging and irresistible while appreciating how he explained the irrationalities in human decision-making drawn from Tversky and Kahneman's research in a clear, relatable manner.^[40] Despite the praise, some reviewers critiqued the book for occasionally prioritizing storytelling over technical depth. The Guardian noted that while Lewis excels at simplifying complex ideas, this approach sometimes skimmed the surface of the psychologists' rigorous methodologies, leaving readers wanting more on the scientific intricacies.^[25] Others pointed to minor over-dramatization in depicting personal conflicts, with Kirkus observing that details of the collaborators' relationship at times overshadowed the broader narrative.^[40] Notable endorsements included positive reactions from figures in the field, and the book holds an average rating of 4.00 out of 5 on Goodreads, based on over 63,000 ratings.^[41] It was nominated for the 2017 Goodreads Choice Award in History & Biography but received no major literary awards.

Commercial performance

Upon its release on December 6, 2016, The Undoing Project achieved immediate commercial success, selling 54,669 copies in its first full week of sales as reported by Nielsen BookScan.^[42] The book debuted at number one on the New York Times Best Sellers list in the business books category on December 18, 2016, and remained on the list for multiple weeks, including positions in the top five through early 2017. It also entered the USA Today Best-Selling Books list at number five in mid-December 2016, marking Michael Lewis's tenth appearance on that ranking.^[43] On Amazon, the book launched at number two in the Psychology Best Sellers category and sustained top-10 placement for several weeks, reflecting strong initial demand in the nonfiction segment.^[34] Internationally, it performed well in the UK, where the hardcover edition was released by Allen Lane on December 6, 2016, and the paperback by Penguin on October 31, 2017, garnering over 10,000 customer reviews on Amazon UK as of 2025, indicating robust market reception across Europe.^[44] The audiobook version, narrated by Dennis Boutsikaris and released simultaneously, contributed to overall sales through platforms like Audible, where it received high ratings and steady streams.^[36] The title's performance was propelled by Lewis's established readership from prior bestsellers such as The Big Short and Moneyball, which had collectively sold millions of copies, alongside the contemporaneous rise of behavioral economics concepts like nudge theory in public policy discussions.^[45] In the years following, the book maintained a long-tail presence with continued reprints by W.W. Norton and expanded digital availability.^[1]

Legacy

Impact on behavioral economics

Michael Lewis's The Undoing Project (2016) provided an accessible narrative of Daniel Kahneman and Amos Tversky's collaboration, amplifying their prospect theory by retelling its development in a way that resonated beyond academic circles and spurred renewed interest in economics journals. Prospect theory, introduced in their seminal 1979 paper, posits that people value gains and losses differently, with losses looming larger than equivalent gains—a concept known as loss aversion. The book's engaging style drew attention to this framework, influencing subsequent economic research on decision-making under risk, particularly in finance where loss aversion explains investor behavior during market downturns. The book also bolstered policy applications of behavioral economics, enhancing the visibility of "nudge" strategies derived from Kahneman and Tversky's insights. Nudge theory, popularized by Richard Thaler and Cass Sunstein, uses subtle environmental cues to guide better decisions without restricting choice, and The Undoing Project reinforced its foundations by humanizing the psychological research behind it. In academic settings, the book enriched the legacy of Kahneman's 2002 Nobel Prize in Economic Sciences, framing his award as a recognition of integrating psychology into economics and inspiring dedicated courses in behavioral economics at institutions like Stanford University. Stanford's Center for Advanced Study in the Behavioral Sciences (CASBS), where both researchers were fellows, highlights the book in its history of the field, using it to illustrate the psych-econ bridge. This narrative has encouraged curricula that emphasize heuristics and biases, fostering interdisciplinary training.^[46] Despite its influence, The Undoing Project faced criticism from some economists who argued it, like Kahneman and Tversky's broader work, oversimplified rational choice models by overemphasizing lab-demonstrated "irrationalities" that may not hold in real-world contexts. Critics such as Gerd Gigerenzer contended these apparent biases are adaptive heuristics, while mainstream economists viewed deviations as marginal and incorporable into existing frameworks without upending neoclassical theory. Nonetheless, the book effectively bridged psychology and economics, mainstreaming these critiques and promoting a more nuanced view of human behavior in economic analysis.^[47] Kahneman's death on March 27, 2024, renewed attention to their partnership and the book's portrayal of it, with obituaries and discussions highlighting its role in popularizing their ideas.^[48]

Cultural influence

The publication of The Undoing Project has contributed to the broader popularization of Kahneman and Tversky's ideas on cognitive biases and decision-making in media formats beyond traditional print. For instance, the book served as a key reference in the 2017 Freakonomics Radio podcast episode "The Men Who Started a Thinking Revolution," which explored the duo's groundbreaking contributions to behavioral economics and their influence on everyday judgments. ^[49] Similarly, their work, as detailed in the book, has been invoked in discussions on decision-making in podcasts like Charles Schwab's Choiceology, where episodes hosted by Katy Milkman delve into psychological traps in high-stakes choices, echoing the heuristics and biases central to the narrative. ^[50] In popular culture, the book has reinforced the application of these concepts in entertainment and self-improvement literature, building on expansions of Kahneman's earlier Thinking, Fast and Slow by integrating biographical insights into analyses of human error. ^[14] Its themes of intuitive flaws have permeated discussions in shows addressing ethics and cognitive shortcuts. The book's emphasis on heuristics has amplified its cultural footprint in sports and business, extending the analytics revolution from Lewis's Moneyball to basketball strategy. Post-2016, NBA teams have increasingly cited Kahneman and Tversky's frameworks in scouting and draft processes to mitigate biases like anchoring, where initial player rankings unduly influence evaluations, as evidenced in analyses of draft inefficiencies. ^[51] In the corporate sphere, the principles highlighted in the book inform training programs on debiasing, with organizations adopting tools from behavioral economics—such as those in Google's re:Work resources—to enhance hiring and team dynamics by countering availability heuristics in decision processes. On a broader scale, The Undoing Project has heightened public engagement with practices aimed at combating biases. Its global dissemination, through translations into at least eight languages including Chinese, Japanese, German, Italian, and Spanish, has enabled discussions in diverse cultural contexts, fostering awareness of decision pitfalls in non-Western settings like community initiatives on risk perception. ^[52]
