Review of Nassim Taleb’s Antifragile

We all know what “fragile” means.  But what is the opposite of fragile?

If you are like me, your instinctive response would be “robust” or perhaps “durable.”  But you would be wrong.

Something that is fragile is damaged by an unexpected shock, whereas something that is robust or durable is able to withstand it.  To be robust is to be neutral to shocks.

But what do you call the true opposite of fragile—something that actually benefits from shocks?

As Nassim Taleb points out, there is no word in English (or in any other language, ancient or modern) that conveys this idea.  So he invented one—antifragile—and wrote an entertaining and enlightening book around the concept.

Taleb is at times playful and even self-effacing in his writing and at other times insufferably arrogant (“non-meek” in his words).  But he is always—and I mean always—thought provoking.

Years ago, before Taleb become something of a celebrity, I picked up his original Fooled by Randomness and had something of a “eureka” moment.  Taleb put into words (and numbers) many of the abstract ideas about risk and randomness that I instinctively felt yet couldn’t articulate (he had that effect on a lot of people, it would turn out).  In particular, I had always mistrusted the Value-at-Risk metric and its offshoots that had been crammed down my throat as an undergraduate finance student.  It registered on my “bulls_t detector”, to borrow one of Taleb’s earthy phrases, and history would vindicate this gut reflex with implosion of the financial system in 2008.

I still consider Fooled to be his best book, and if you have never read Taleb’s work that is where I would recommend you start.  But Antifragile: Things That Gain From Disorder expands on the concepts in Fooled and its follow-up The Black Swan and goes far beyond financial markets into a more general theory of randomness and volatility and their importance in life and nature.  “Living things are long volatility,” he emphasizes often.

Perhaps Taleb’s greatest gift as a writer is his ability to speak in metaphors, the best of which is his analogy of the Procrustean Bed (see my review of Taleb’s The Bed of Procrustes).

Procrustes was a nasty little fellow from Greek mythology who would invite guests into his home and then either stretch or amputate parts of their legs to make them fit just right in his guest bed.  In Taleb’s analogy, much of the modern world is a Procrustean bed of sorts.  People, markets, and economic systems are contorted to fit tidy theories.

But in Antifragile, Taleb goes beyond this “square peg in a round hole” argument to a larger critique of “soccer moms” (both figurative and literal) who naively attempt to make the world safer by “sucking randomness out to the last drop.”  Doing this provides the illusion of safety while actually making us less resilient and more fragile.  In other words, not only are scraped knees and bruises ok, they are an essential part of growth.

Many readers misunderstand Taleb’s core message.  They assume that because Taleb writes about unseen and improperly calculated risks, his objective must be to reduce or eliminate risk.  Nothing could be further from the truth. 

If anything, Antifragile is a celebration of risk and randomness and a call to arms to recognize and embrace antifragility.  Rather than reduce risk, organize your life, your business or your society in such a way that it benefits from randomness and the occasional Black Swan event.

Taleb’s own life is a case in point.  He had the free time to write Fooled, The Black Swan and Antifragile because—in his own words—he made “F___ you money” during the greatest Black Swan event of our lifetimes, the 1987 stock market crash.   And to demonstrate that Taleb’s trading style is antifragile, had the 1987 crash never happened, Taleb would not have been materially hurt.  His trading style puts little at risk but allows for outsized returns.

In what may seem somewhat disturbing to some readers (and Taleb himself is disturbed by it as well), what makes a system antifragile is that its individual pieces are perishable.  Natural selection—the survival of the fittest—requires that the unfit are allowed to fail.

Using the example of restaurants, the restaurant sector is robust because the failure of any one restaurant does not affect the others.   And the restaurant sector is antifragile because the remaining players actually learn and grow from witnessing the mistakes made by the failed restaurant.

Now, compare this to the banking system.  The world banking system is inherently fragile because the failure of one bank leads to contagion that can cause the failure of other banks and of the system itself.

The importance of failure to an antifragile system is a recurring theme to the book.  As individuals and as a collective, we learn more from mistakes than from successes.  In a capitalist system, you need a replenishable  supply of entrepreneurs willing to take risks.  For every failed business idea, our knowledge base expands.

Taleb goes so far as to advocate we treat ruined entrepreneurs in the same way we honor dead soldiers, “perhaps not with as much honor, but using the same logic.”

As Taleb explains, just as “there is no such thing as a failed soldier, dead or alive (unless he acted in a cowardly manner), likewise there is no such thing as a failed entrepreneur  or failed scientific researcher.”   Their sacrifice makes the system stronger.

I commend Taleb on another book well written, and I recommend Antifragile along with Fooled by Randomness and The Black Swan.

    He has no respect for soldiers. He is antirespectful.

    1. Sergio,

      Please don’t mistake bad writing on my part for disrespect on Taleb’s part.  Taleb is actually very respectful of soldiers throughout his books.  In the part I was quoting, he was merely making an analogy.  My apologies to both Taleb and the readers of the review if that is how it came across.
