Antifragile Things That Gain from Disorder
Reviews

Lots of good principles but the combativeness got tiring in the end.

Longwinded way to prove how cultured the author is.

Taleb is always good at challenging one's intuitive thinking about systems and processes, and illustrating it with case studies. This was a good encouragement to build redundancy into our practices, and avoid as much as possible creating big systems with a single point of failure. A key insight here is that methods and practices that have lasted a long time have been exposed to many black swans in their time, and are more likely to be robust, or even antifragile, into the future. An informative and enjoyable read on its own terms, but quite sobering in the context of two long years of ill-advised interventions by experts into almost every area of life. If you are looking for assurance and confidence that Big Pharma and government regulators will take care of you, I encourage you to read something else.

Nassim is a bro who loves to talk about how much stronger he is compared to other economics because he squats and enjoys olive oil (not kidding). So that stuff is darn tough to slog through (although sometimes its face-palmingly amusing). I kept reading because there are some diamonds between all the other crud. His commentary on iatrogenics is great "Harm done by a healer: Doctors who default to intervention who end up doing more harm than good" and the First Principal of Iatrogenics "We do not need evidence of harm to claim a drug or unnatural via positivia procedure is dangerous. Lack of evidence of harm does NOT imply there is no harm: Only time will tell". Overall, its a slog through a haystack with quite a few needles of classical wisdom: Case in point: "A book thats been in print for 400 years will continue to be in print longer than a book thats been in print for only 10 years."

** spoiler alert ** Good intro to explain what's antifragile and resilience difference. Human body benefits from acute stress but not chronic. Learn to benefit from one observation which adds antifragility and flanourety Enjoy life. ≥Anything that experiences more upsides than downsides from random occurrences possesses anti-fragility ≥Things that benefit from randomness and chaos while resilient objects resist disorder and remain the same. Fragility is associated with experiencing more downsides than upsides, a direct opposite of antifragility. ≥“Antifragile”. This object gets better from experiencing stress to a degree nonetheless. ≥The finally but not the least is Antifragility, the Hydra describes antifragility through its ability to grow two heads when one is cut. This shows something that grew, developed and became hard after undergoing stresses. ≥enjoys favorable asymmetry ≥Antifragility comes from a system that overcompensates and builds extra capacity in anticipation of future and greater stress. ≥Stressors to Antifragile objects are merely information about the environment it finds itself in. Although antifragility has conditions, humans do better with acute stress than chronic stress because of recovery time, which allows the body to process the information, and adapt before another stress is inflicted on it. ≥Many problems we face in the modern age arise from the removal of natural stressors. ≥Antifragility is the combination aggressiveness plus paranoia — clip your downside, protect yourself from extreme harm, and let the upside, the positive Black Swans, take care of itself. We saw Seneca’s asymmetry: more upside than downside can come simply from the reduction of extreme downside (emotional harm) rather than improving things in the middle. ≥Talk to either undergraduate students, cab drivers, and gardeners or the highest caliber scholars; never to middling-but-career-conscious academics. If you dislike someone, leave him alone or eliminate him; don’t attack him verbally.” ≥Prediction is impossible, it was in past and is so now more than ever. So, instead of trying to predict what is going to happen, just position yourself in such a way that you have options ≥Having options allows you to benefit from the positive side of uncertainty, without a corresponding serious harm from the negative side. ≥“Touristification” is a part of modern life that treats humans as machines, with simplified mechanical responses and a detailed user’s manual. It is the removal of uncertainty and randomness from things, trying to make things as predictable as possible to their smallest details, all that for the sake of comfort, convenience, and efficiency. ≥The rational flâneur is someone who makes a decision at every step to revise his plans, so he can implement things based on new information he has acquired. The flâneur does not allow him or herself to become a prisoner of a plan. Tourism assumes one can plan out everything and this gets one locked into a hard-to-revise program, while the flâneur is continuously and, most importantly, rationally modifying his goals as he acquires information. ≥His modus operandi was that people do not really know what they want until you provide them with it. ≥He learned how trade successfully using the process of Random Tinkering (antifragile), Heuristics (technology), Practice. and Apprenticeship without ever actually understanding what green lumber really was. ≥Having options provides you with favorable asymmetries or positive convexity. When uncertainty arises, optionality causes you to outperform the average. This is a very central property of life ≥Antifragility has more chances against the randomness of our reality, unlike fragility or robustness. ≥The process of elimination is what makes things thrive and become antifragile. ≥Subtractive epistemology, which is the act of removing what we think is wrong, is the greatest contribution to knowledge. ≥One observation can disprove a statement, while a million observations barely confirms it, disconfirmation is more thorough than confirmation. ≥If true wealth consists in worriless sleeping, clear conscience, reciprocal gratitude, absence of envy, good appetite, muscle strength, physical energy, frequent laughs, no meals alone, no gym class, some physical labor (or hobby), good bowel movements, no meeting rooms, and periodic surprises, then it is largely subtractive (elimination of iatrogenics). ≥The Lindy effect is a great guide when selecting which book to read, books that have been around for millennia or two should remain around for quite a long time. ≥Empedocles, a pre-Socratic philosopher, was asked why a dog preferred to always sleep on the same tile. His answer was that there had to be some likeness between the dog and that tile. This does not follow rationalism but rather is confirmed by its mere reoccurrence. Those technologies that have survived are like the tile to the dog, a match, because they resonate with something deep in our nature. ≥What Nature does is rigorous until proven otherwise; what humans (and science) do is flawed until proven otherwise. ≥A weak person is not a person that does not have an opinion, it someone who does not take risks for his or her opinions. Dignity is worth nothing unless you work to earn it and are willing to pay price for it. ≥What is Skin in the game? It is simply the imposition of consequences for failure to perform tasks appropriately.

(c) 'Accidental Fish', 2013 "Nothing convinces us of our capacity to make choices — nothing sustains our illusion of freedom — more than our ability to regularise our behaviour. nothing is more capable of destroying our interest and our pleasure in what we do. If it is the predictable that stupifies us and the unpredictable that terrorises us, what should we do? If we are always caught between risk and resignation, between confidence and catastrophe, how can we decide what to do next?"— Adam Phillips My problem is what my mother kept telling me: I'm too messianic in my views. — Taleb The most ambitious and messy book in his idiosyncratic four-volume work of evolutionary epistemology, the 'Incerto'. (It is Fooled By Randomness , Black Swan , Bed of Procrustes , and yonder.) The former three books are largely critical, hacking away at theory-blindness, model error, and the many kinds of people he sees as possessing unearned status (economists, journalists, consultants, business-book writers): this is the upswing, a chaotic attempt to give general positive advice in a world that dooms general positive advice. Every other page has something worth hearing, for its iconoclasm, or a Latin gobbet, or catty anecdote, if not something globally and evidently true. I think he is right about 30% of the time, which is among the highest credences I have for anyone. I only think I am 35% right, for instance.* But a core point of his system is that his approach should work even given our huge and partially intractable ignorance. The core point, repeated a hundred times for various domains: In real life, many systems deteriorate without an irregular supply of stressors (non-fatal negative events), and actually benefit from them by constructively overreacting. By robbing such 'antifragile' systems of stressors, modern approaches to managing them do damage in the guise of helping out.** This observation leads to his grand theory of everything: every system is either fragile (damaged by volatility), robust (resistant to damage from volatility), or antifragile. This isn't a trivial distinction, because each has formal properties that allow us to change arrangements to, firstly, prevent explosions, and then to gain from chance volatility. Biology is definitely one of these antifragile systems***; his case that, absent gross financialisation, the global economy would be one is convincing too; and the idea's at least plausible when applied to the cultivation of virtue or existential strength in a single person. The danger with this - an indissoluble danger because there can be no general strategy to avoid it - is that in welcoming constructive stress we'll miss the point at which the welcomed dose turns destructive (where fasting starts to atrophy, where training becomes masochism, where critique becomes pogrom, where sink-or-swim encouragement turns abuse). * This claim is remarkable for both its extreme vagueness and apparent arrogance. Here is a post to handle the former fact. And the latter: It might strike you as beyond arrogant to assume that you just so happen to be the most reliable inference device in the world, but that doesn't (have to) follow from my claim above, which results from the trivial thought “I believe my own beliefs most”, instead. (Consider the converse: if I came to view anyone as more reliable than me, the rational thing to do would be to incorporate their truer views (and, better, their methods) until I again thought of myself as at least their equal. So, either one believes the superficially arrogant position “I believe my beliefs most” – or else one must believe that one is incapable of adapting enough to superior methods when faced with them, or else one must believe that one cannot know which methods are best. So the above assumption is more about having a high opinion of rational adjustment than impossible egotism, I think. Good news! We can now calibrate ourselves, at least for the most sensational and available predictions using this cool thing.^ Finally!: The fully-unpacked, properly defensible assumption might be something more like: “I am the agent that I know to be most transparently reliable or unreliable; I assume I’m adjusting properly to better methods; as such I have at least equal confidence in my own belief set, compared to the best known alternative agent's.”) ^ You might wonder if this argument suggests that I should have 100% confidence in my beliefs. No; even if I was the best inferrer, I would suffer uncertainty because of the opacity of my errors: that is, I know I'm often not right but don't know exactly whereabouts I'm not right. Also from the unsystematic internal PredictionBook every non-psychopath has ("wisdom is knowing you'll be an idiot in the future"). And another source of uncertainty is down to the unknowable (like what stocks will crash next week). I do worry that, whatever my particular self-credence estimate is, the whole approach is subtly wrong somewhere – since "40%" gives the impression that I think of myself as a worse guide to the world than dumb chance^^ – but I think it works. Particularly if much of the missing 60% is made of safe scepticism rather than errors. ^^ For binary event spaces – but, really, how many of those are there in real life? ** He credits the formal basis of all this to Jensen's inequality, in a chapter which might be the clearest expression of the idea there is. *** (In particular species-level evolution, but also organism-level health.) ************************************************************* Some pigeonholes you might think to put all this in: * Conservative? Yes; but a good-hearted Burkean (“Antifragility implies that the old is superior to the new… What survives must be good at serving some purpose that time can see but our eyes and logical faculties can’t capture…”). Most people are conservative over some things (e.g. the natural world; we just happen to call that conservationism instead). Also approves of any high technology that removes anything he views as a disease of civilisation, like these things were supposed to be. So, in general, conservative only in the sense that existential risk people are.* * Economic conservatism. Only sort of; he's a trader, and would have speculation free to flow provided that deposit banks were nationalised first, and prioritises deficit reduction in a way we associate with conservatives but which e.g. Sweden pulled off without any lasting social justice sting. More formally he is against centralisation on both moral and technical grounds; that is likely a principle with some conservative effects, justified, in theory, by its keeping us alive. (Life-critical politics.) Laissez faire? No: he recommends radical change to e.g. science funding, but no decrease. Big fan of Switzerland’s government, read into that what you will. He sees “optionality”, an originally financial concept, as the solution to fragility risks and the key to success in every domain there is. This isn’t at all as economistic as it sounds; the sacred and the humane somehow fit perfectly into his core rationalist agenda, persistence through change. * Social conservatism? No sign; no discussion of discrimination. Some people think such abstention is oppressive, but they are probably wrong. * Social Darwinist? Nah. * Bioconservative? Absolutely; he describes himself as the ‘diametric’ opposite of Ray Kurzweil, and he’s in full uproar over the global risk posed by synthetic biology (and recently fleshed out this horror in highly rigorous terms). * Anti-intellectual? Not at all! Only anti-academia, and they still do not represent the whole of quality intellectual life. Hates irresponsible ‘canned methods of inference’ too (statistical significance, etc). * Lacrimist? (That is, does he glorify suffering?) Not quite. He certainly views comfort as vitiating. His opposition to transhumanism is too quick and doesn't take the moral challenge of a world of pained beings seriously enough, for me. * Macho? Hm. Well, nature has made certain challenging actions optimal. Amusing proto-paleo attitude, too: * I, for my part, resist eating fruits not found in the ancient Eastern Mediterranean (I use “I” here in order to show that I am not narrowly generalizing to the rest of humanity). I avoid any fruit that does not have an ancient Greek or Hebrew name, such as mangoes, papayas, even oranges. Oranges seem to be the postmedieval equivalent of candy; they did not exist in the ancient Mediterranean. * His work fits the x-risk paradigm very well, but he developed his edifice in complete isolation from them, and has an uncompromising scepticism about expected value that might not make cross-overs all that fruitful. ************************************************************* How original is the core point, really? Well, who cares? His claim is that he had to invent the word 'antifragile', not the idea. He says, idiosyncratically, that Seneca and Nietzsche had the nub of the idea, and Jensen the formal essence; Darwin certainly did too. "Resilience engineering" and in computing, 'defensive programming' (b. 1998) and 'self-healing systems' (b. 2001) are at least on the same track, though not getting beyond a lively sort of robustness. But I doubt that most systems can become antifragile - e.g. it's hard to imagine an antifragile jet engine (one that harvests bird strikes for fuel, or soot cleaning)? So maybe it's only the grand generalisation to all design that's new. ************************************************************* Gripes: His footnotes are collected by theme rather than linked to his claims directly, which makes it so difficult to follow up his sources that his credibility suffers. He namedrops, which is not the same as showing his working. I would really like to see his backing for his cool claims (about e.g. an irregular sleep pattern as a good thing, or things like ‘I suspect that thermal comfort ages people’), but it’s hidden away and often one-study. (Again: apparently one-study, since his working is not easily on show.) He has a surprisingly high opinion of Steve Jobs – who I view as a grand example of an empty suit: there are 9 references to Jobs’ hokey shark-wisdom, (where Gigerenzer and Mandelbrot get 8, Jensen gets 7, Marx 7). Does Jobs really count as a ‘practitioner’ with ‘skin in the game’? Eh. His homebrew jargon starts to drag – some sentences are wholly composed of his neologisms plus a barrel of articles and prepositions. (I used the glossary early and often.) Repetitive: tells what he’ll tell you, tells you he’s told you. Some passages really suffer from his wholesale hostility to copy-editing; there are some flatly bad sentences here. And he namedrops a lot, more than fair attribution of ideas – there are several passages that are just lists of people he likes (e.g. p.257-8). I don't see that it's worthwhile to criticise his arrogant style; it's what animates his points, and he never uses it on weak targets. Lastly, he sometimes makes of a system’s persistence the highest good. (Where its persistence is to be contrasted with mere stability.) This is in tension with his wonderful emphasis on artistic and quasi-sacred values elsewhere in the book. But it talks about everything, is historically wide-eyed, relentlessly rational, and often funny. And the method-worldview-style it suggests might stop life crushing us utterly.

Best idea in this book: consider the downside as well as the upside, and systemic perverse incentives can largely be corrected by ensuring decision-makers have skin in the game. For these ideas, read Taleb's other book called "Skin in the Game" and throw this one in the trash. Every real-world example he gives of something "anti-fragile" could be considered simply "resilient," so I doubt that it exists outside of mythology, like his example of the Hydra, which grows 2 new heads for each decapitation it experiences. Long discussion on how nonlinear systems are anti-fragile, but it's more descriptive than definitive. He deplores his favorite straw men "Soviet Harvard Academics" for not understanding these systems with curves. (They do; they formulated them.) On the one hand, academics are all ivory tower fools who don't understand his real-world economics papers like all these business people seem too, and on the other hand, these business people don't get the value of his theoretical foresight like these academic people who invited him to speak seem to. On the one hand, doctors who are in the trenches know way more than academics who never leave their labs who arrogantly think their ideas will somehow survive working on flesh and blood patients, and on the other hand these foolish old timers used to use leeches, for crying out loud, rather than understand the mechanisms and pathways of disease. Vitamins aren't real, icing your broken nose is disrespectful to nature, and will you alternative medicine types stop calling me already -- "the approach of this book is ultra-Orthodox, ultra-rigorous, and ultra-scientific; certainly not in favor of alternative medicine." He simultaneously champions evidence based medicine and decries past ignorant practices. You can't have the first without the other. Practical application of theory on a population and monitoring the results is how we learn what works and what doesn't. If you are attempting the visceral experimentation he advocates, you'll inevitably find something that doesn't work and is in fact harmful 20 years down the line. There literally no other way to "just know" what the best way is, like he implies. The only takeaway here is this book is a great example of ego justification.

I am a fan of Taleb’s previous book. This one seems to be a bit over my head

Nassim Taleb does a good job of helping us understand how certain systems gain from disorder, however I had that idea down after the first 200 pages. This book is far too long to recommend to anyone casually interested in these ideas, and it is a bit puzzling why he goes into so much depth on some issues and than glosses over others. Overall I enjoyed it, just wished it were a bit shorter.

It's the first time I get to read Nassim and it was a ride. There's something intriguing about the way he narrates his vision of life through every chapter. The main topic here is a concept he created and called "antifragility". He explains its relation to non-linearity and our fragile world exploring medicine, government, corporate topics and more. Although the overall text seems scientific, the way it's told helps the naive reader understand the concepts. It's full of examples and theories that the author finds a way to place through each chapter. I'm definitely intrigued by him after finishing this book and will aim forward to looking for more of his work. Recommended for sure 👌🏼

This was a singularly unpleasant reading experience. There are a few pearls of insight and wisdom here; too bad they are buried in a burdensome avalanche of useless vitriol, contradictions, and half-truths.

Bold, erudite, prophetic. This book itself is antifragile. Kudos.

Enjoyed his other books and this was also thought-provoking. It builds on his other books, so some of the concepts are not new, but he expands on them, and applies them to more of a comprehensive worldview. I understand and agree with much of what he says, and I'm left thinking about how that should affect some non-trivial aspects of my life. References to and quotes from ancient writers weren't that helpful to me and they got a little tiresome. Favorite nuggets: - "The hidden benefit of antifragillity is that you can guess worse than random and still end up outperforming." - "Negative knowledge is more robust than positive knowledge" - "How many things must one disregard in order to act?"

The first few chapters are really interesting. The rest was really a waste -- pretty disappointing after The Black Swan.

Very interesting though a bit long and difficult read. Finally I got used to Taleb's writing style. Antifragility is actually something I've been attracted to in life for a long time. Now I have a good name for that concept. Recommended read and there's plenty of food for thought. [reading time: 19h35m]

Non fiction that taught me a few things and made other things I followed much clearer. Much love for daddy taleb

Brilliant. This is the best of all the books that Taleb has written so far.

It's like he turned a really interesting essay into a sub-par book. Save yourself and just read the introduction. Book gets very repetitive and doesn't redeem itself. Hardly explores the other side of the argument except to demean it. Although the ideas are very interesting, the tone and delivery are grating, and not really worth the time.

I love the concept of this book, but it's too long and the author is kind of a dick. I suggest reading the intro and then stopping. I read the intro and the first section and then skimmed the rest because I found it such a slog.

The notion of antifragility is fascinating and widely applicable. A few notes: * mother nature is antifragile and has been tinkering slowly over time, we should admit she's much wiser than we can be and be humble when proposing changes that go against it (e.g., diet, exercise, etc.) * organizations that are large are fragile, black swan events can have huge impacts in many people. Need to control for these. * government does best when smaller and thus the incentives align to do well for the people. when large government it's easy to get divorced from the people as incentives don't align. * company managers often don't have the right incentives. if they make a "big positive impact" they can get huge bonuses. if subsequently the company crashed due to their changes, they don't lose their prior pay and bonuses. thus no incentive to carefully build for the long term.

This one had interesting points, but as someone who focuses around systems and order, it was hard for me to imagine structuring systems in this way. The examples were interesting -- things like the human body and vaccines as an example of a system that grows stronger after trauma.

Thought-proving and entertaining. At times even funny. But jeebus, Taleb really makes you work for it. There’s basically no structure to the book (a feature rather than a bug, Taleb apparently wanted to make life miserable for book reviewers who he suspects of not reading the texts (no structure means forcing a read through). Apparently, this was more important than making for a good reading experience). And the language (Taleb likes coming up with his own words) means you’ve got to really pay attention throughout. It pays to create and keep a glossary handy. But it’s worth it. Kind of (and I feel OK saying that because I know Taleb doesn’t give a hoot; he’s funny that way). Overall I feel richer having read it.

This book has a powerful main idea, sinthesized in the word "Antifragile". The concept deserves a clearer word. Taleb offers us a few interesting anecdotes, many of which you may have heard before. But he goes for way too long without a nice structure, or trying to build a rapport with the reader. It's a pity, because the core idea of things that improve from stress seems very helpful. I'd say read a summary and you'll be fine.

Highlights

When constrained systems, those hungry for natural disorder, collapse, as they are eventually bound to, since they are fragile, failure is never seen as the result of fragility. Rather, such failure is interpreted as the product of poor forecasting. As with a crumbling sand pile, it would be unintelligent to attribute the collapse of a fragile bridge to the last truck that crossed it, and even more foolish to try to predict in advance which truck might bring it down. Yet it is done all too often.

To summarize, the problem with artificially suppressed volatility is not just that the system tends to become extremely fragile; it is that, at the same time, it exhibits no visible risks. Also remember that volatility is information. In fact, these systems tend to be too calm and exhibit minimal variability as silent risks accumulate beneath the surface. Although the stated intention of political leaders and economic policy makers is to stabilize the system by inhibiting fluctuations, the result tends to be the opposite. These artificially constrained systems become prone to Black Swans. Such environments eventually experience massive blowups, of the type seen in Figure 3, catching everyone off guard and undoing years of stability or, in almost all cases, ending up far worse than they were in their initial volatile state. Indeed, the longer it takes for the blowup to occur, the worse the resulting harm to both economic and political systems.

As Fat Tony said, Socrates was put to death because he disrupted some- thing that, in the eyes of the Athenian establishment, was working just fine. Things are too complicated to be expressed in words; by doing so, you kill humans. Or people-as with the green lumber--may be focusing on the right things but we are not good enough to figure it out intellectually.
I’ve always agreed that some approaches are more impactful for humans since they’re more emotional/narrative-based rather than logical, e.g. religion as a way to keep us aligned with our long-term goals. But this made me shift my perspective and see our language as limited, not humans as limited. Language not only makes things “logical” but also simplifies them to a point where it misses the nuances that are the most significant.

Nietzsche's famous expression “what does not kill me makes mestronger" can be casily misinterpreted as meaning Mithridatization or hormesis. It may be one of these two phenomena, very possible, but it could as well mean “what did not kill me did not make me stronger, butspared me because I am stronger than others; but it killed others and theaverage population is now stronger because the weak are gone." In other words, I passed an exit exam.

While sacrifice as a modus is obvious in the case of ant colonies, I am certain that individual businessmen are not overly interested in hara-kiri for the greater good of the economy; they are therefore necessarily concerned in seeking antifragility or at least some level of robustness for themselves. That's not necessarily compatible with the interest of the collective—that is, the economy. So there is a problem in which the property of the sum (the aggregate) varies from that of each one of the parts—in fact, it wants harm to the parts. It is painful to think about ruthlessness as an engine of improvement.

Every plane crash brings us closer to safety, improves the system, and makes the next flight safer—those who perish contribute to the overall safety of others. Swiss flight 111, TWA flight 800, and Air France flight 447 allowed the improvement of the system. But these systems learn because they are antifragile and set up to exploit small errors; the same cannot be said of economic crashes, since the economic system is not antifragile the way it is presently built. Why? There are hundreds of thousands of plane flights every year, and a crash in one plane does not involve others, so errors remain confined and highly epistemic whereas globalızed economic systems operate as one: errors spread and compound.
