问题     Towards the end of Thinking, Fast and Slow, Daniel Kahneman laments that he and his late collaborator, Amos Tversky, are often credited with showing that humans make "irrational" choices. That term is too strong, he says, to describe the variety of mental mishaps to which people systematically fall prey. Readers of his book may disagree. Mr. Kahneman, an Israeli-American psychologist and Nobel economics laureate, has delivered a full catalogue of the biases, shortcuts and cognitive illusions to which our species regularly succumbs. In doing so he makes it plain that Homo economicus — the rational model of human behaviour beloved of economists — is as fantastical as a unicorn.
    In one experiment described by Mr. Kahneman, participants asked to imagine that they have been given ￡50 behave differently depending on whether they are then told they can "keep" ￡20 or must "lose" ￡30 — though the outcomes are identical. He also shows that it is more threatening to say that a disease kills "1,286 in every 10,000 people", than to say it kills "24.14% of the population", even though the second mention is twice as deadly. Vivid language often overrides basic arithmetic.
    Some findings are downright peculiar. Experimental subjects who have been "primed" to think of money, perhaps by seeing a picture of dollar bills, will act more selfishly. So if someone nearby drops some pencils, these subjects will pick up fewer than their non-primed counterparts. Even obliquely suggesting the concept of old age will inspire people to walk more slowly — though feeling elderly never crossed their mind, they will later report.
    After all this the human brain looks less like a model of rationality and more like a giddy teenager: flighty, easily distracted and lacking in self-awareness. Yet this book is not a counsel of despair. Its awkward title refers to Mr. Kahneman’s two-tier model of cognition: "System 1" is quick, intuitive and responsible for the quirks and mistakes described above (and many others). "System 2", by contrast, i$ slow, deliberative and less prone to error. System 2 kicks in when we are faced with particularly complex problems, but much of the time it is all too happy to let the impulsive System 1 get its way.
    What, then, is System 1 good for? Rather a lot, it turns out. In a world that often demands swift judgment and rapid decision-making (fight or flight?), a creature who solely relied on deliberative thinking wouldn’t last long. Moreover, System 1 generally works well. As Mr. Kahneman says, "most of our judgments and actions are appropriate most of the time". He urges readers to counteract what he considers to be mistakes of System 1 thinking, such as the "loss aversion" that deters people from accepting favourable gambles (such as a 50-50 chance to win $200 or lose $100). He also recommends checking the performance of an investment portfolio no more than once a quarter, to limit needless anguish over short-term fluctuations and the "useless churning" of shares.
    Mr. Kahneman does not dwell on the possible evolutionary origins of our cognitive biases, nor does he devote much time to considering why some people seem naturally better at avoiding error than others. Still this book, his first for a non-specialist audience, is a profound one. As Copernicus removed the Earth from the centre of the universe and Darwin knocked humans off their biological perch, Mr. Kahneman has shown that we are not the paragons of reason we assume ourselves to be. Often hailed as the father of behavioural economics (with Tversky as co-parent), his work has influenced a range of disciplines and has even inspired some policy. But the true consequences of his findings are only starting to emerge. When he presents the poor victims of his experiments with conclusive proof of their errors, the typical reaction is not a chastened pledge to shape up, but confused silence, followed by business as usual. No one likes to be told he is wrong.
What is the book, Thinking, Fast and Slow, mainly about?
选项 A、Why people are not that rational as imagined.
B、How people’s thinking pattern develops.
C、Why some people are better decision-makers than others.
D、How people develop cognitive biases.
答案A
解析 推理判断题。文章开篇提出了<思考，快与慢>这本书的结论：人们并非完美的理性思维者：接着列举实验证明人类不是完全理性的；然后进一步解释原因，人们为什么不能理性思考；可见这本书的主要内容是分析为什么人们不是完美的理性主义者，即[A]。文章最后一段第一句讲到本书中卡尼曼并没有详述我们认知偏见的进化源头，也没有花太多笔墨解释为什么有些人天生就比其他人善于规避错误，由此可以排除[C]和[D]。[B]没有提到。
