Thinking Fast and Slow经典读后感10篇(3)

　　我们都知道之前的学术界倾向于研究第一个方向：理性的行为。因此，Kahneman & Tversky系统的揭示非理性决策的工作的确是异常重要的。现在我基本上不从目的上质疑了，不过第三个层次也回答了我之前的感觉。第三个层次应该是那些总问“so what”问题的人所向往的。但是目前，不论前两个层次如何，进入第三个层次——让我们觉得那些决策中的bug不再那么可怕——鲜有吧。

　　下面来介绍一位一直和Kahneman & Tversky对着干的吧：Gerd Gigerenzer，这位就是死活都支持rationality的吧，读文献前完全不了解情况，就看见作者单位是：Max Planck Institue for Psychology Research，感觉这个单位也是个神一样的存在吧，料想作者一定也不是什么无名小辈呀，查了下，再次证明我的孤陋寡闻和基础知识薄弱啊。这位光是科普书就写了好几本畅销的啊：simple heuristics that make us smart；calculated risks；Gut Feelings。一本没读过，但是后两本都听说过，最后一本更是看到之前友邻说“和Kahneman的观点完全反着，读着很费劲”。现在一下把所有之前零碎存储的记忆都连在一起了，就像周末要上映的《云图》的感觉似的。两者的争论除了之前提到的第一个层次和第二个层次外，还有对于Frequencist and Bayesian/personal Theory的争论。前者认为：“probability is a measure of relative frequencies of particulat event. Unless probability statement based on such proportion is meaningless, it should not be none.” 而后者则主张：“probablity judgment can be cased on any of one's believed knowledge including knowlegde about frequencies or about a set of logivcal possibilities as well as other knowledge.” 其实看来看去我也不是非常明白，但是可见Gigerenzer主张前者，而Kahneman & Tversky支持后者。这个我也要再读读文献才有进一步的发言权呀。先不讨论了。

　　最后吐槽一下学术界吵架呀，这几篇文章读得非常逗就是因为两方在文章中露骨直白的打架简直太好玩了。比如，Kahneman & Tversky说：“this is a fact of life that targets of criticism should learn to expect, even if they do not enjoy it. in some exceptional cases, however, the fidelity of the presentation is so low that readers may be misled about the real issues under discussion. In oue view, Gigerenzer's critique of the hueristics and biases preogram is one of these cases......” 个中乐趣还要各位自己去读文献体会了。

　　最后的最后：你猜Kahneman的老婆是谁？在Kahneman & Tversky的Science文章1126页右下角的这个段落开头谈到趋中回归时说“in the normal corse of life, one encounters many instances of regression towars the mean, in the comparison of the height of fathers and sons, of the intelligence of husband and wives, or of the performance of individuals on consevutive examinations.” 班里一个女同学特意提出抗议说为什么啊！凭什么啊！她其实只是想表达一下自己的愤怒。但其实八卦在于Tversky的老婆是谁，Kahneman的老婆又是谁啊！我也是今天第一次知道，孤陋寡闻啊：Tversky's wife is Barbara Tversky and Kahneman's wife is Anne Treisman. 但是我还没找到真正的槽点在哪里，到底谁高谁矮啊？

　　《Thinking Fast and Slow》读后感(八)：Thinking twice, carefully

　　I haven't made any thought on how to "label" this book yet.Daniel Kahneman's book brings new explanation for human's behavior, and the motivation behind it. Just like whatJim Holt wrote on NYTimes, this is the real "Two Brains Running", since "System 1 is impulsive and intuitive; System 2 is capable of reasoning, and it is cautious, but at least for some people it is also lazy".

　　It is a book related to psychology, economics, finance, philosophy, and most important, human behavior. This book reminds me that why the Department of Economics is just on the top floor of the Department of Psychology in CMU. Just like a hint, these two disciplines could bring some combination, and it does.

　　Thinking Fast: Not Bad It varies, however, it works for someone. "Thinking fast" shouldn't be a mistake, or something else.

　　ome people just "compute" fast, and for most of us,we often compute much more than we want or need. Dr. Kahnemancalls this excess computation "the mental shotgun". In a little while, the collegues may complain that "you are thinking too much". Dr. Kahneman argues that random processes produce many sequences that convince people that the process is not random after all.

　　o the coincidence is not like the incidence we haven't imagined before.“To the untrained eye,” Feller remarks, “randomness appears as regularity or tendency to cluster.”

　　It's not a shame for people who think really fast, and "predict" things like wizard.

　　Thinking Slow: Think Twice The shortcoming for thinking fast is that luck is not always on your side. In another word, you can't make your own chance everytime. So how about thinking it twice？

　　The professional basketball player is just a good example. For those top shooters,tv commentators may chant for the "hot hand". However,After analyzing of thousands of sequences of shots led to a disappointing conclusion: there is no such thing as a hot hand in professional basketball, either in shooting from the field or scoring from the foul line.

　　You may get the illusion for the latest two games, or five games. But trust me, as a fan of Kobe Bryant for two decades, I fully understand the ups and downs. One day the basket looks like an ocean, while in another day there's a lid on the top. …… 此处隐藏：2424字，全部文档内容请下载后查看。喜欢就下载吧 ……
