System 1 is fast, intuitive, and emotional; System 2 is slower, more deliberative, and more logical. The impact of overconfidence on corporate strategies, the difficulties of predicting what will make us happy in the future, the profound effect of cognitive biases on everything from playing the stock market to planning our next vacation—each of these can be understood only by knowing how the two systems shape our judgments and decisions. Engaging the reader in a lively conversation about how we think, Kahneman reveals where we can and cannot trust our intuitions and how we can tap into the benefits of slow thinking. He offers practical and enlightening insights into how choices are made in both our business and our personal lives—and how we can use different techniques to guard against the mental glitches that often get us into trouble. Topping bestseller lists for almost ten years, Thinking, Fast and Slow is a contemporary classic, an essential book that has changed the lives of millions of readers.

Book excerpt: From the Nobel Prize-winning author of Thinking, Fast and Slow and the coauthor of Nudge, a revolutionary exploration of why people make bad judgments and how to make better ones—"a tour de force” (New York Times). Imagine that two doctors in the same city give different diagnoses to identical patients—or that two judges in the same courthouse give markedly different sentences to people who have committed the same crime. Suppose that different interviewers at the same firm make different decisions about indistinguishable job applicants—or that when a company is handling customer complaints, the resolution depends on who happens to answer the phone. Now imagine that the same doctor, the same judge, the same interviewer, or the same customer service agent makes different decisions depending on whether it is morning or afternoon, or Monday rather than Wednesday. These are examples of noise: variability in judgments that should be identical. In Noise, Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein show the detrimental effects of noise in many fields, including medicine, law, economic forecasting, forensic science, bail, child protection, strategy, performance reviews, and personnel selection. Wherever there is judgment, there is noise. Yet, most of the time, individuals and organizations alike are unaware of it. They neglect noise. With a few simple remedies, people can reduce both noise and bias, and so make far better decisions. Packed with original ideas, and offering the same kinds of research-based insights that made Thinking, Fast and Slow and Nudge groundbreaking New York Times bestsellers, Noise explains how and why humans are so susceptible to noise in judgment—and what we can do about it.

The first chapter begins with Daniel Kahneman's description of two main characters of the book, neither of which are people. He refers to something that he calls System 1 and System 2. System 1 is dedicated to thinking fast. It almost solely relies on intuition and almost entirely disregards information. System 1 is in control every time we do an activity that requires quick thinking and reactions. For example, System 1 in in control when we drive, when we want to read other people's facial expressions, when we answer to questions that require quick answers, etc. Kahneman states that System 1 is involuntary and operates entirely on its own. System 2 thinks slowly and always relies on information and almost never on intuition. System 2 is in control when we try to solve difficult math problem, when we want to focus our attention on the voice of person in a room full of people, when we fill in tax forms, or during any other events that are based on awareness. System 2 requires energy, because it operates voluntarily.

Available in PDF, EPUB and Kindle. Book excerpt: “Brilliant. . . . Lewis has given us a spectacular account of two great men who faced up to uncertainty and the limits of human reason.” —William Easterly, Wall Street Journal Forty years ago, Israeli psychologists Daniel Kahneman and Amos Tversky wrote a series of breathtakingly original papers that invented the field of behavioral economics. One of the greatest partnerships in the history of science, Kahneman and Tversky’s extraordinary friendship incited a revolution in Big Data studies, advanced evidence-based medicine, led to a new approach to government regulation, and made much of Michael Lewis’s own work possible. In The Undoing Project, Lewis shows how their Nobel Prize–winning theory of the mind altered our perception of reality.

Book The Hedgehog and the Fox

  • Author : Isaiah Berlin
  • Publisher : Princeton University Press
  • Release : 2013-06-02
  • ISBN : 1400846633
  • Pages : 143 pages

Download or read book The Hedgehog and the Fox written by Isaiah Berlin and published by Princeton University Press. This book was released on 2013-06-02 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The fox knows many things, but the hedgehog knows one big thing." This ancient Greek aphorism, preserved in a fragment from the poet Archilochus, describes the central thesis of Isaiah Berlin's masterly essay on Leo Tolstoy and the philosophy of history, the subject of the epilogue to War and Peace. Although there have been many interpretations of the adage, Berlin uses it to mark a fundamental distinction between human beings who are fascinated by the infinite variety of things and those who relate everything to a central, all-embracing system. Applied to Tolstoy, the saying illuminates a paradox that helps explain his philosophy of history: Tolstoy was a fox, but believed in being a hedgehog. One of Berlin's most celebrated works, this extraordinary essay offers profound insights about Tolstoy, historical understanding, and human psychology. This new edition features a revised text that supplants all previous versions, English translations of the many passages in foreign languages, a new foreword in which Berlin biographer Michael Ignatieff explains the enduring appeal of Berlin's essay, and a new appendix that provides rich context, including excerpts from reviews and Berlin's letters, as well as a startling new interpretation of Archilochus's epigram.

Book Superforecasting

Download or read book Superforecasting written by Philip E. Tetlock and published by Crown. This book was released on 2015-09-29 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: NEW YORK TIMES BESTSELLER • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY THE ECONOMIST “The most important book on decision making since Daniel Kahneman's Thinking, Fast and Slow.”—Jason Zweig, The Wall Street Journal Everyone would benefit from seeing further into the future, whether buying stocks, crafting policy, launching a new product, or simply planning the week’s meals. Unfortunately, people tend to be terrible forecasters. As Wharton professor Philip Tetlock showed in a landmark 2005 study, even experts’ predictions are only slightly better than chance. However, an important and underreported conclusion of that study was that some experts do have real foresight, and Tetlock has spent the past decade trying to figure out why. What makes some people so good? And can this talent be taught? In Superforecasting, Tetlock and coauthor Dan Gardner offer a masterwork on prediction, drawing on decades of research and the results of a massive, government-funded forecasting tournament. The Good Judgment Project involves tens of thousands of ordinary people—including a Brooklyn filmmaker, a retired pipe installer, and a former ballroom dancer—who set out to forecast global events. Some of the volunteers have turned out to be astonishingly good. They’ve beaten other benchmarks, competitors, and prediction markets. They’ve even beaten the collective judgment of intelligence analysts with access to classified information. They are "superforecasters." In this groundbreaking and accessible book, Tetlock and Gardner show us how we can learn from this elite group. Weaving together stories of forecasting successes (the raid on Osama bin Laden’s compound) and failures (the Bay of Pigs) and interviews with a range of high-level decision makers, from David Petraeus to Robert Rubin, they show that good forecasting doesn’t require powerful computers or arcane methods. It involves gathering evidence from a variety of sources, thinking probabilistically, working in teams, keeping score, and being willing to admit error and change course. Superforecasting offers the first demonstrably effective way to improve our ability to predict the future—whether in business, finance, politics, international affairs, or daily life—and is destined to become a modern classic.

Book Economic Dignity

Download or read book Economic Dignity written by Gene Sperling and published by Penguin. This book was released on 2021-10-12 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Timely and important . . . It should be our North Star for the recovery and beyond.” —Hillary Clinton “Sperling makes a forceful case that only by speaking to matters of the spirit can liberals root their belief in economic justice in people’s deepest aspirations—in their sense of purpose and self-worth.” —The New York Times When Gene Sperling was in charge of coordinating economic policy in the Obama White House, he found himself surprised when serious people in Washington told him that the Obama focus on health care was a distraction because it was “not focused on the economy.” How, he asked, was the fear felt by millions of Americans of being one serious illness away from financial ruin not considered an economic issue? Too often, Sperling found that we measured economic success by metrics like GDP instead of whether the economy was succeeding in lifting up the sense of meaning, purpose, fulfillment, and security of people. In Economic Dignity, Sperling frames the way forward in a time of wrenching change and offers a vision of an economy whose guiding light is the promotion of dignity for all Americans.

Book excerpt: INSTANT NEW YORK TIMES BESTSELLER A NEW YORK TIMES NOTABLE BOOK OF 2018 ONE OF THE ECONOMIST'S BOOKS OF THE YEAR "My new favorite book of all time." --Bill Gates If you think the world is coming to an end, think again: people are living longer, healthier, freer, and happier lives, and while our problems are formidable, the solutions lie in the Enlightenment ideal of using reason and science. By the author of the new book, Rationality. Is the world really falling apart? Is the ideal of progress obsolete? In this elegant assessment of the human condition in the third millennium, cognitive scientist and public intellectual Steven Pinker urges us to step back from the gory headlines and prophecies of doom, which play to our psychological biases. Instead, follow the data: In seventy-five jaw-dropping graphs, Pinker shows that life, health, prosperity, safety, peace, knowledge, and happiness are on the rise, not just in the West, but worldwide. This progress is not the result of some cosmic force. It is a gift of the Enlightenment: the conviction that reason and science can enhance human flourishing. Far from being a naïve hope, the Enlightenment, we now know, has worked. But more than ever, it needs a vigorous defense. The Enlightenment project swims against currents of human nature--tribalism, authoritarianism, demonization, magical thinking--which demagogues are all too willing to exploit. Many commentators, committed to political, religious, or romantic ideologies, fight a rearguard action against it. The result is a corrosive fatalism and a willingness to wreck the precious institutions of liberal democracy and global cooperation. With intellectual depth and literary flair, Enlightenment Now makes the case for reason, science, and humanism: the ideals we need to confront our problems and continue our progress.

Book excerpt: The brain is a fearsomely complex information-processing environment--one that often eludes our ability to understand it. At any given time, the brain is collecting, filtering, and analyzing information and, in response, performing countless intricate processes, some of which are automatic, some voluntary, some conscious, and some unconscious.Cognitive neuroscience is one of the ways we have to understand the workings of our minds. It's the study of the brain biology behind our mental functions: a collection of methods--like brain scanning and computational modeling--combined with a way of looking at psychological phenomena and discovering where, why, and how the brain makes them happen.Want to know more? Mind Hacks is a collection of probes into the moment-by-moment works of the brain. Using cognitive neuroscience, these experiments, tricks, and tips related to vision, motor skills, attention, cognition, subliminal perception, and more throw light on how the human brain works. Each hack examines specific operations of the brain. By seeing how the brain responds, we pick up clues about the architecture and design of the brain, learning a little bit more about how the brain is put together.Mind Hacks begins your exploration of the mind with a look inside the brain itself, using hacks such as "Transcranial Magnetic Stimulation: Turn On and Off Bits of the Brain" and "Tour the Cortex and the Four Lobes." Also among the 100 hacks in this book, you'll find: Release Eye Fixations for Faster Reactions See Movement When All is Still Feel the Presence and Loss of Attention Detect Sounds on the Margins of Certainty Mold Your Body Schema Test Your Handedness See a Person in Moving Lights Make Events Understandable as Cause-and-Effect Boost Memory by Using Context Understand Detail and the Limits of Attention Steven Johnson, author of "Mind Wide Open" writes in his foreword to the book, "These hacks amaze because they reveal the brain's hidden logic; they shed light on the cheats and shortcuts and latent assumptions our brains make about the world." If you want to know more about what's going on in your head, then Mind Hacks is the key--let yourself play with the interface between you and the world.

Book The Psychology of Money

Download or read book The Psychology of Money written by Morgan Housel and published by Harriman House Limited. This book was released on 2020-09-08 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doing well with money isn’t necessarily about what you know. It’s about how you behave. And behavior is hard to teach, even to really smart people. Money—investing, personal finance, and business decisions—is typically taught as a math-based field, where data and formulas tell us exactly what to do. But in the real world people don’t make financial decisions on a spreadsheet. They make them at the dinner table, or in a meeting room, where personal history, your own unique view of the world, ego, pride, marketing, and odd incentives are scrambled together. In The Psychology of Money, award-winning author Morgan Housel shares 19 short stories exploring the strange ways people think about money and teaches you how to make better sense of one of life’s most important topics.

Book The Obstacle Is the Way

Download or read book The Obstacle Is the Way written by Ryan Holiday and published by Penguin. This book was released on 2014-05-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: #1 Wall Street Journal Bestseller The Obstacle is the Way has become a cult classic, beloved by men and women around the world who apply its wisdom to become more successful at whatever they do. Its many fans include a former governor and movie star (Arnold Schwarzenegger), a hip hop icon (LL Cool J), an Irish tennis pro (James McGee), an NBC sportscaster (Michele Tafoya), and the coaches and players of winning teams like the New England Patriots, Seattle Seahawks, Chicago Cubs, and University of Texas men’s basketball team. The book draws its inspiration from stoicism, the ancient Greek philosophy of enduring pain or adversity with perseverance and resilience. Stoics focus on the things they can control, let go of everything else, and turn every new obstacle into an opportunity to get better, stronger, tougher. As Marcus Aurelius put it nearly 2000 years ago: “The impediment to action advances action. What stands in the way becomes the way.” Ryan Holiday shows us how some of the most successful people in history—from John D. Rockefeller to Amelia Earhart to Ulysses S. Grant to Steve Jobs—have applied stoicism to overcome difficult or even impossible situations. Their embrace of these principles ultimately mattered more than their natural intelligence, talents, or luck. If you’re feeling frustrated, demoralized, or stuck in a rut, this book can help you turn your problems into your biggest advantages. And along the way it will inspire you with dozens of true stories of the greats from every age and era.

Book The Ingenious Mr  Pyke

Download or read book The Ingenious Mr Pyke written by Henry Hemming and published by PublicAffairs. This book was released on 2015-05-05 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The untold story of an enigmatic genius who changed warfare forever In the World War II era, Geoffrey Pyke was described as one of the world's great minds -- to rank alongside Einstein. Pyke was an inventor, adventurer, polymath, and unlikely hero of both world wars. He earned a fortune on the stock market, founded an influential pre-school, wrote a bestseller, and came up with the idea for the US and Canadian Special Forces. In 1942, he convinced Winston Churchill to build an aircraft carrier out of reinforced ice. Pyke escaped from a German WWI prison camp, devised an ingenious plan to help the Republicans in the Spanish Civil War, and launched a private attempt to avert the outbreak of the Second World War by sending into Nazi Germany a group of pollsters disguised as golfers. And he may have been a Russian spy. In 2009, long after Pyke's death, MI5 released a mass of material suggesting that Pyke was in fact a senior official in the Soviet Comintern. In 1951, papers relating to Pyke were found in the flat of "Cambridge Spy" Guy Burgess after his defection to Moscow. MI5 had "watchers" follow Pyke through the bombed-out streets of London, his letters were opened, and listening devices picked up clues to his real identity. Convinced he was a Soviet agent codenamed Professor P, MI5 helped to bring his career to an end. Henry Hemming is the first reporter to sift through this extraordinary new information and finally tell Pyke's astonishing story in full: his brilliance, his flaws, and his life of adventures, ideas, and secrets.
