　　《Antifragile》读后感(一)：Arrogance and Insight

I started reading this book at a very difficult stage of my life. After three and a half years' hard work and sacrifice, I didn't get what I want the most, and ended up lining with people I had despised the most before. When I tried to figure out what was really wrong about the world (or about me), the word "uncertainty" bumped in my head. I wasn't unfamiliar with this concept owing thanks to my rigorous behaviors economics study experience. I know Burke, Alchain, Hayek, Coase and Kahneman who talk about uncertainty and trail and error probably even more than Taleb does.
That's why I wasn't quite moved by Taleb's new concepts when I started this book. I've learned more than enough to know there is actually nothing really new in the newly-branded bottles. Taleb talks about how nature mother embraces wisdom that are not fully comprehended and respected by we stupid arrogant human beings; he talks about how uncertainly and randomness take control of our lives; and he talks about how meaningless and counterproductive people are by trying to stay away from uncertainty instead of making use of it. Even though Taleb's choice of words are clever, his story fascinating, his delivery provocative and authoritive enough to influence readers. I know for sure that's not enough for a long-lasting book.
Taleb remains a successful if not genius writer. He knows how to trigger readers' curiosity and emotions, and he knows how to decorate his book with what catches people's attention( if it's not his editor's credit)-- Who don't want to know how to survive in a highly random world？ But after finishing this book, people get nothing but some murky abstract principles which even couldn't be called valuable lessons-embrace uncertainty and choose the one with more upside opportunities. If by any means this book can satisfy ordinary readers, it still can't answer the questions of people who have already been in the field with questions wondering in their mind for years.
However, there is something really arresting in the last part of the book about the agency problem, and that's the essence of the book from my point of view. It's about Taleb's observation about the increasingly twisted world. In the old days, human beings had developed a system of social values that favored the bunch of people who take risks on their own and benefit others. The old world's bravest and smartest people were willing to throw themselves in the sea of uncertainty( more of downside chances) in the pursuit of honor. But in the new world, the rule changed. Everyone is satisfied of themselves as short-cuts takers. They benefited from others taking downside chances either by watching aside and learning from others' mistakes delightedly, or by making criticism freely and easily while taking no responsibilities of what they had to say. In Taleb's eyes, the new world is extremely dangerous, if not falling faster. I'm afraid his insight is too right and fierce at this point.
Here followes some quotations that I find are interesting:
 My experience is that money and transactions purify relations; ideas and abstract matters like “recognition” and “credit” warp them, creating an atmosphere of perpetual rivalry.
The excess energy released from overreaction to setbacks is what innovates!
The record shows that,for society, the richer we become, the harder it gets to live within our means.Abundance is harder for us to handle than scarcity.
This mechanism of overcompensation hides in the most unlikely places. If tired afteran intercontinental flight, go to the gym for some exertion instead of resting. Also, it is awell-known trick that if you need something urgently done, give the task to the busiest(or second busiest) person in the office. Most humans manage to squander their freetime, as free time makes them dysfunctional, lazy, and unmotivated—the busier they get,the more active they are.
someone who, after making a mistake,doesn’t introspect, doesn’t exploit it, feels embarrassed and defensive rather thanenriched with a new piece of information, and tries to explain why he made the mistakerather than moving on. These types often consider themselves the “victims” of somelarge plot, a bad boss, or bad weather.
Jean-Jacques Rousseau wrote, citing him: “Itseemed, wrote Machiavelli, that in the midst of murders and civil wars, our republicbecame stronger [and] its citizens infused with virtues.… A little bit of agitation givesresources to souls and what makes the species prosper isn’t peace, but freedom.”
One of life’s packages: no stability without volatility.
In his attack onAverroes, he expressed the famous idea that logic excludes—by definition—nuances,and since truth resides exclusively in the nuances, it is “a useless instrument for findingTruth in the moral and political sciences
Steve Jobs: “People thinkfocus means saying yes to the thing you’ve got to focus on. But that’s not what it meansat all. It means saying no to the hundred other good ideas that there are. You have topick carefully. I’m actually as proud of the things we haven’t done as the things I havedone. Innovation is saying no to 1,000 things.”
Amateursin any discipline are the best, if you can connect with them. Unlike dilettantes, career professionals are to knowledge what prostitutes are to love.
what Mother Nature does is rigorous untilproven otherwise; what humans and science do is flawed until proven otherwise.
Never ask anyone for their opinion, forecast, or recommendation. Just askthem what they have—or don’t have—in their portfolio.
Suckers try to win arguments, nonsuckers try to win
Sissies are born, not made.They stay sissies no matter how much independence you give them, no matter howrich they get.

1 Summary
----------
1.1 Introduction
==========
Taleb conveniently quotes one of his friend's summary of this book: "Everything gains or loses from volatility. Fragility is what loses from volatility and uncertainty."
I think the point is better expressed by rephrasing: "Antifragility is what gains from volatility and uncertainty, up to a point. And being antifragile is a good thing."
Well, that's pretty much summarizes this 500-pages-long book. The rest is an accumulation of more or less relevant topics, delivered in Taleb's trademarked seering, holier-than-thou, hero-or-moron style. Why, even in "Dynamic hedging", his first, $100-book on trading exotic options, he was already both immensely entertaining and almost unbearably infuriating.
1.2 A few of the more interesting points:
=========================
1.2.1 Every phenomenon in the world belongs to one of the following categories:
Fragile: vulnerable to unforeseen shocks
Robust: indifferent to shocks
Antifragile: thrive on shocks, up to a point.
That's what Taleb calls the Triad.
1.2.2 Most modern structures are inherently fragile
Salaried employment: while it looks safe on the surface (predictable salary every month) it is subject to the catastrophic risk of losing one's job.
Debt-fueled economies: debt has no flexibility, so these economies can't stand even a slowdown without risking implosion (cf current situation)
Modern societies: efficiency demands are pushing the structures to the maximum, so a little sand in the cogs make the whole edifice totter.
Touristification: turning adventures (kids growing up, people visiting foreign countries) from exciting, dangerous activities into bland, Disneyfied and safe ones.
1.2.3 Ways to be antifragile include:
Stressors: it is healthy to be subject to some punctual stresses to awake the organism from complacency (e.g. irregular meal times, violent exercise or ingesting small amounts of poison)
Barbell strategy: put 90% of your eggs into something super-safe and be very risk-seeking with the other 10% (swing for the fences).
Optionality: get into situations where downside is limited but upside is unlimited (non-linearity)
Redundancy: have more than one way to have things done.
Less is more: don't add unnecessary things.
Tinkering: empiricism is better than top-down academic research
Small is beautiful: large organizations are inherently fragile, but small structures are well adapted to be nimble and profit from unexpected opportunities.
1.2.4 For small troubles, better trust nature and do nothing than bring untested methods that can have tragic unforeseen consequence
Beware of neomania: don't embrace novelty for the sake of it
Stick to time-tested methods: what has stood the test of time has proved to be robust
Don't sweat the small stuff if it can lead to tragedy: radiation used to cure acne leading to leukemia, thalidomide prescribed to reduce morning sickness leading to malformed babies.
1.2.5 An antidote to the lack of accountability seen in the powerfuls who rule us (government officials, corporate honchos, bankers)
Have them have skin in the game, i.e. to share in the downside of their decisions. Taleb quotes the 3000-year-old+ Hammurabi code, "eye for an eye, teeth for a teeth."
2 Review
---------
So, what's the score？ As with his other books, I found myself reading every page the first 40-50 pages, then turning the pages faster and faster as the neat, amusing prose turns into Fidel Castro-style interminable ramblings, hyperboles and inaccuracies, annoying personal anecdotes, and worst of all, the silly little tales with his imaginary heroes Nero Tulip and Fat Tony (Tulip seems to be some kind of idealized version of Taleb himself). One or two hours for the first third, 40 minutes for the second and 15 minutes for the last.
And I'll spare (or maybe not) the "very technical" appendix 2 with its silly little formula he seems to be so proud of. Thanks for teaching us high-school math about convexity (Jensen inequality as if it were rocket science？ Come on!)
The basic point is sound however: we sure all need a bit more antifragility in our lives.
If we only ditched what is unnecessary (going to the doctor for trivial stuff, seeking novelty for the sake of it, buying stuff we don't need), we'd have gone a long way toward being more robust.
But going beyond that is more problematic: Taleb waxed lyrical about the upside of antifragility, but he says nothing about its cost.
And seeing how he came to his idea from the world of options trading, it looks dishonest. In options trading, when you buy an option and get all the good stuff associated with it (unlimited upside, limited downside), the flipside is that it costs money everyday (time decay). Spending all your time buying options is quite a good way to the poorhouse.
As in the financial world, so in the real world, unless you're talking about "free optionality" (the people who don't have skin in the game that Taleb reviles). Maybe being a free agent beats being an office drone because one doesn't need to fear getting fired, but what about the daily stress of needing to go out and find work without any certainty to get it？ That's a cost that's a bit too high for probably most people.
In conclusion, this is an imperfect, overlong and often eye-roll-inducing book (as is usual for Taleb), but it presents an intriguing and original argument for the reader to chew on.

　　《Antifragile》读后感(三)：Antifragile book review

There're much to be said about the book. It's loaded with both insights and rubbish.
Similar to the points in the Fooled by Randomness, Taleb repeated the point of differences in impact between frequent events and rare events. Rare events can always negate the efforts for frequent events. Building on that, Taleb proposes the asymmetry strategy, which quotes "provide for the worst and let the best handle itself". On average, the asymmetry is expected to have positive outcomes statistically.
The other part of the book deals largely with benefiting from the disorder or randomness in almost every aspects of lives. There're some points that makes sense, such as trial and error strategy, which Taleb considers derived from optionality. There are lots of others that do not really makes sense. For example, Taleb keeps emphasizing the lots of previous discoveries and inventions come from unintended efforts in stead of intended studies, and thus current planned scientific studies are not effective. In here, Taleb obviously missed the point that unintended discoveries come from continuous focused professional studies. Systematic organized studies prepare scientists for push the boundaries of current knowings forward.
It is the same logic with strategic planning in business organizations. Strategic planning are planned not necessarily to be followed step by step, but to be improved with new information. It's both retrospective and prospective. Taleb looks only at the prospective aspects and consider all planning as probabilistic, but fail to look at the retrospective aspects that people use for planning.

　　《Antifragile》读后感(四)：Connecting the Dots

这本书我觉得写得不好 但是里面有些东西对我影响很大，所以还是写一些 不好的地方： 全书比较缺乏组织，经常不知所云，缺乏对于中心观点的归纳 而且语气很强烈，导致经常想要跟作者对骂 好的地方： --------下面写重点了----- 全书重点：flexibility & randomness 从小，我们被告知，人应该有一个目标，然后不断的向这个目标去努力，然后你就会成功。比如从小立志当科学家，于是从小努力学习科学知识，最后当上科学家。或者运动员，或者艺术家，等等等等 但是并不是这样 比尔盖茨在小时候从来没有想过，他长大要写windows,要创建微软 乔布斯并没有想过他在小的时候就要做iPhone Paul Graham并没有想过，他要创办YC，要当天使投资人 因为这些东西在他们小时候根本就"不存在"，这些东西都是他们所创造的，所以没办法去“立志” 在小的时候，孩子们的想法，无非是当老师/科学家而已，因为对世界的认知限度就是如此。随着对于世界认识的增长，目标也自然产生变化。所以，要求从小就盯着一个目标去努力，这样是不对的。 更何况，这样就失去了创造新职业的机会（比如天使投资人这种职业，在我们小时候并不存在） 所以，目标应该是灵活多变的，即“flexibility”。 具体的思想，其实可以看这里： http://www.paulgraham.com/hs.html 乔布斯在Stanford斯坦福的演讲中，有一句名言“Connecting the dots." 指的是，他在学字体设计 (calligraphy) 的时候，完全是出于无聊。但是字体设计，以及其后所代表的用户体验、设计感，却是苹果的标志性特征。可是，当时他并不是出于什么目的去学的，也就是说： 真正有帮助的东西，未必是有意得到的 为什么？因为未来其实是不可预测的。对于IT这种行业，更加如此。所以很难抱有目的的去说，做这个就会有用，做那个就会没用。You never know 而Anti-fragile，就是指的像乔布斯这样，通过不确定性来获益。 一件事情做好了，究竟有什么回报？这个是非常难以预测的 （这里我觉得大家可以想想自己的经历） 那是不是所以我们的行为都应该不报目的？具体还是推荐看看上面Paul Gramham的那篇文章 --------------- 最后说一下，阿北也给这本书打了高分，为什么呢？ 因为豆瓣也是这样的一个产物。在他做豆瓣的时候，他大概也没有想到，从此之后的10年，都会在这里了。

　　《Antifragile》读后感(五)：脆弱、坚固、和“反脆弱”

如果说《Fooled by Randomness》是线性叙事，讨论的是随机性问题，《The Black Swan》讨论的是重复叙事，讨论的是肥尾效应，《The Bed of Procrustes》是随机叙事，讨论的是各种奇葩的人生哲学，那么畅销作家Nicholas Nassim Taleb的新书《Antifragile》则是集大成者。
《Antifragile》总体的核心是讨论随机性、复杂性和肥尾效应，但其结构是分散性的，所以里面涉及了从古典哲学到纽约宅男等各种各样的内容，而这些内容都万变不离其宗，都是为了说明Taleb提出的一个新概念：“反脆弱”。
在《Antifragile》中，Taleb指出世界上的万物可以分为三类：脆弱（fragile）、坚固（robust）、和“反脆弱”（anti-fragile）。脆弱的东西在变化和压力面前不堪一击，坚固的东西能够抗压，反脆弱的东西则能够从变化和压力中获益。
这个理论可以应用于生活的方方面面，而这一理论带来的很多结论都可能是令人出乎意料的。比如，一个人是伦敦的出租司机，另一个则是伦敦城金融公司的人力资源总监，这两个人谁的生活更为稳定、更为安全？ Taleb给出的答案是：出租司机的工作要稳定和安全得多。
对于企业乃至公共机构，Taleb也进行了同样的分析。在他看来，大多数现代企业和机构强调“效率”。然而，带来效益的规模化、速度等特性，恰恰让这些企业和机构变得脆弱。Taleb把这些企业比喻成一辆高速行驶的大型轿车：车的规模越大、速度越快，出事故的可能性也就越高，事故所能造成的危害也就越大。
然而，很多管理层往往意识不到这一点，或者有意而为之。对于那些“愚蠢”的管理层来说，他们没有意识到每年20%的增长，5年后一次性的亏空，还不如每年都不增长的保本强。对于那些“邪恶”的管理层，他们意识到了高速增长再亏空是不利的，但他们同样意识到，他们可以在5年高速增长期尽量分红，最后企业亏空后弃之不理。对于这些管理层来说，他们本身是反脆弱的，因为企业越脆弱，他们获利越多。
Taleb认为，太过脆弱是整个社会的问题。现在，我们需要的更多是变得坚固和反脆弱，而不是继续考虑如何变得更为高效。而要解决这个问题，我们除了需要调整自己的心态之外，还需要解决社会中错误的激励制度（比如让管理层和企业同样脆弱，而不是让管理层随着企业的脆弱而变得反脆弱）。
对《Antifragile》一书，我认为有两点需要赞许。首先，这本书是有大量养分的。不论书中是否每个论点都成立，Taleb至少提出了一个新颖的观点，汇总了大量的知识。第二，Taleb本人的态度让人非常喜欢。这并不是说Taleb是个完人。实际上，从《The Bed of Procrustes》开始，Taleb就变得越来越傲慢，从他在亚马逊上回答本书书评的态度上，这种傲慢更是一览无遗。然而，Taleb做到了不惧权威、独立思考、而且身体力行。Taleb的很多观点我很赞同，因此读此书除了学习之外，还有杨过看《九阳真经》“模模糊糊的悟到，从没想得这般清楚”的感觉。

　　《Antifragile》读后感(六)：股票交易员教科学家工程师怎么飞？

（书还没看完，先吐槽一下免得忘了）
这个家伙终于走上邪路了，天才与疯子仅一线之隔，我看作者在向后者靠拢。本来作者对于经济问题的分析还是很有建树的，但在此书中他试图将经济问题分析的方法上升到哲学角度，并以此来指点科学和技术的发展，这个就犯了他自己总结的“教鸟儿怎么飞”的错误。
套用政治书的词汇，“教鸟儿怎么飞”意指完全用理论来指导实践的错误。现在的问题是作者研究过科学，做过技术开发吗？没有实际做过研发，就靠几个研究科学技术历史的家伙的言论就能得出技术发展不需要科学的结论，难道不正好是试图用理论来指导实践吗？
作者试图把Trial and error搞成自己的一大发现，殊不知这个就是科学方法的基础。而作者试图说明技术研发不需要科学理论，就用Trial and error就可以。如果研发这么简单那计算机早就能做研发了，因为计算机搞Trial and error比人快的多。问题是绝大多数情况下trial的空间超级大，如果你随机去try那花了整个宇宙的年龄也不一定能碰上你想要的结果，这时候有理论的指导就很重要了。作者反复提喷气引擎是先有实践，然后才有理论，但想没想过如果没有理论，当年原始的引擎能否发展到现在的版本？更何况有很多发明确实是理论在先，比如图灵和现代数字计算机，更不用说GPS需要考虑相对论效应的例子了，只不过作者不知道或者不愿面对这些而已。这里作者又犯了了自己书中提到的Confirmation bias错误。
总之作者试图将研究现代经济得出的结论推广到其他领域或者未来是行不通的，所看不起的Directed research也正是未来的技术研发的发展方向，随着计算机能力的提高和我们对复杂系统理解的加深，模型的作用会越来越大。只是因为在过去瞎猫碰死耗子的方法吃的开并不等于未来也会这样，这里作者又犯一个自己书中提出的思维错误。
