MINI LECTURE 14 A First Course on Fragility, Convexity, and Antifragility (Nontechnical).

[@PhaBaria]

This is your best explanation so far for this phenomenon - for the non-technical audience, at least. Thanks.

[@kompjutr]

This could have an application in so many fields for those who have ears to hear. Splendid.

[@mandalorets2607]

I can not stop watching your lectures, which makes me practice my english. Hey from Ukraine:) You are very cool

Only thing better than Fridays are Fridays when Nassim posts a lesson.

[@justinthring558]

Professor Taleb, friend, Thank you for this lecture, very helpful. Looking forward to lecture B. Kind regards.

[@aukehunneman6371]

This explanation is so good! The importance of these concepts can hardly be overstated. Thank you Nassim!

[@antoniojaim7532]

When you talk about the Art and why we buy it, mimetic desire Rene Girard. and Shanon's information teory and his relation about improbability and information.

[@AlwaysAudacity]

Fantastic presentation, simple and very thought-provoking. I particularly like the segment where you talk about dynamism on a ventilator, half the time at 80% and half the time at 120%. I just so happened to be reading the Effective Executive by Peter Drucker. He mentions in the book that top executives don't spend much time thinking about averages, because those don't tell you much. The effective executive has to understand the extremes.

[@FINANCIALFREEDOMCJ]

Wow. It’s awesome to see the mathematical side of Antifragility. I have been reading the Black Swan but have been binge watching the videos that it seems like I can’t find time to finish it. It’s crazy watching older videos and seeing these things play out. Great video!

Very good Nassim. This makes it very intuitive why you need a short in the body for making tail bets

James, could you explain please?

[@surajitgoswami1871]

This is exactly the problem in Diabetes: non-linearity in fragility! Doctors use fasting glucose and give the patient a clean bill of health because fasting glucose remains flat for 10-20 years and then curve sharply upwards when it is diagnosed as Type 2 diabetes. In medicine, one could look for a different indicator as well. For example, using fasting insulin (more difficult to measure than fasting glucose) could have told of the deteriorating health situation because fasting insulin goes up linearly as the cells are getting insulin resistant.

Thank you Nassim. You briefly mentioned Intermittent Fasting but I didn't understand the example. Any chance you could elaborate a bit?

[@dobrinstoilov]

I think his argument is that humans are not created for eating 3/4/5 (fixed N) meals a day, but rather to eat then there is food (so - variability). Thus, the recently made popular intermittent fasting, is found to have benefits - because it brings variability to eating. So, human body 'likes' variability in eating (in terms of how many per day) as it becomes 'stronger' (I think the research points to better immune system), hence the human body is antifragile to the n of eatings per day. *This is at least my interpretation, not a medical advice*

[@CalebRox]

@@dobrinstoilov I believe that we actually do prefer to eat at the same time each day, in fact you have probably experienced hunger at around the same time you are used to eating… so I don’t buy that aspect of IF.

[@thoms4384]

Can you talk about law of large numbers with theories living in the asymptote while they should be living the pre-asymptote ? Thanks

[@marceldavis430]

15:20 i have gotten from somewhere(poor memory) that we do a sigh ~every 5 minutes since our alveoli collapse every now and then and they need a little more force to inflate again. (See trying to inflate a balloon thats wet on the inside) Is the higher survival rate when doing 80/120 vs 100 associated to that or do we not currently know anything as to the reasons?

[@marceldavis430]

Oh never mind, just reading Antifragile atm and noticed you mention it aswell

[@iArkyy]

Thanks Mr. Taleb! Im currently writing a master thiesis on goodwill accounting. Is it possible to say that the companies are fragile in regards to rising discount rates (as they are used to determine current carrying value)? Since its not allowed to increase the value of goodwill (using DCF) to record profits in the income statement. The function that is net profits should be concave to the discount rate used in calculating carrying value that could lead to potenital write downs.

[@martag.6778]

Please, could you edit your videos for the option of subtitles in Brazilian Portuguese. I'm Brazilian from São Paulo and I have difficulty with the English language. I appreciate if you can fulfill my request . I'm your fan.

[@derrickheng564]

Naive question here, for the example shown in time index 10:00, while the first order differential may appear be non linear, but would it be plausible that the second order differential be linear?

[@Esyr33]

Great lesson! Thank you!

[@salmantabatabai]

Thank you for sharing Prof Taleb. What I understood was that there is an extent in which non-linearity is advantageous. In your weight lifting example, it would be more beneficial to lift 100 pounds 10 times (average 100) than doing 9 days 0 and 1 day 1000 (again average 100). I think finding this extent is quite crucial for becoming antifragile. Am I correct?

[@RichardKinch]

Haha, the KZbin auto captions detect the chalkboard eraser sounds as "[Music]", so Taleb is going to get a copyright strike for infringing somebody else's copyrighted chalkboard erasing performance.

[@jasdeepsinghgrover2470]

Thank you for your amazing work... Going by your amazing book on randomness... Won't something anti-fragile which makes small losses in low volatility risk getting eliminated in long streaks of low volatility?

[@experimentsinAI]

Brilliant thanks

[@DengueBurger]

good quality

[@golchha_J]

Hi Nassim, I wanted to ask *why* we have in-built convexity to some stressors? As to concavity to harm, it makes sense - we encounter the tails of the distribution less often? And thank you for posting this.

[@kennethmckeever842]

Sounds like some X are a “shock” when X is less than some normal range and when X is greater. The distributions don’t need to be symmetrical. It was initially confusing when I saw X

[@IsaacWendt]

x Doesn't predict f(x) - (seems similar to charlie munger's inverse thinking) Everything fragile doesn't like volatility Everything f(x) is nonlinear. In order for something to break you need an accelerating function. avg of the function is worse than the function of the avg. convex = smile face. concave = sad face. Side note: I would pay alot to be taught how to think like Taleb. Imagine a teacher of this caliber Also would love to see a real-life example in options or mispricing in options. As a case study

greetings from mexico city Im delightfluly reading your book the spanish version of the Black swan . Im just starting but please when you say this is a novel a idea and is not inspired over someones elses ideas I guess you have to admit that at least you know who CArlos Guinzburg and David Bohm are, speacially regarding the ideas of the unkown soldier and the platonism, regarding both authors and ideas respectively. anyway. Im just delighted. Im on page 67. booket version.

Can anyone expand on why over redundancy in supply chains can lead to worse outcomes?

[@RichardKinch]

Redundancy to improve ordinary logistics will make the extraordinary logistic situations worse. That is, it increases concavity in the system. Improving the handling of normal situations performs disproportionately poorly when situations are not normal. That's concavity.

[@nntalebproba]

No, redundancy is necessary to avoid spikes.

[@victordelegrego3748]

@@nntalebproba I would apreciate if the Maestro could give me an initial clue about where to look for the answer.

[@RichardKinch]

@@nntalebproba Agreed, if by "redundancy" you mean "spare transport capacity that is usually idle". But then you can't supply seasonal fruit out of season just by adding redundant capacity. So it depends on what you mean by "spikes".

Gaal Dornick, using non-mathematical concepts, has defined psicohistory to be the branch of mathematics which deals with the reactions of human conglomerates to fixed social and economic stimuli.... ...Implicit in all these definitios is the assumption that the conglomerate being dealt is sufficienly large for valid statistical treatment. The neccesary size of such a conglomerate may be determined by Seldon's First Theorem which...A further neccesary assumption is that the human conglomerate be itself unaware of psycohistoric analysis in order that its reactions be truly random...
