Black Swan Review | Lexaholik.com

Reader Alex passed along his recent The Black Swan book review.

Why Do You Recommend This Book?

The Black Swan made me realize that living a carefully planned out life is a mistake. I remember after I first read the book at the now-closed Borders on Michigan Ave in Chicago while I was still in law school. Afterwards, I walked around outside dazed and confused, and feeling like I’d been living my life all wrong.

What was in the book?

A lot of information, actually, but everything sort of revolves around just a few core principles that stick with me to this day:

  • The events with the greatest impact in your life (Black Swans) are unexpected;
  • They are unexpected because of a variety of cognitive biases; and
  • No matter how hard we try, we will fail to predict these consequential events.

Think back to the biggest events in the U.S. of the past few decades. We’re talking about things like the Internet becoming popular, the terrorist attacks on 9/11, or the Global Financial Crisis. None of these things were expected or predicted. If you read books/articles these days, they all describe a linear history where these things were expected to happen. There’s a ton of hindsight bias in written history, and Taleb gives us more specific details as to why.

SOUL IN THE GAME, Real World Risk, Rebellion, Voting to Destroy the Establishment | Facebook

Reader: “Dear N., I have read all your books and have a question. How do you recommend an average young man navigate the modern world? “.

Me: “Never ask a vague question“. (3/13/16)

SOUL IN THE GAME & THE RISE OF PROTECTIONISM

The rise of protectionism may have a strong rationale. One fundamental flaw with economic thinking is that humans are assumed to be doing things to make a living and improve their economic condition. This is partially true. But people are also doing things for existential reasons. We may be better off economically (in the aggregate) by exporting jobs. But that’s not what people may really want.

I write because that’s what I am designed to do –and subcontracting my research and writing to China or Tunisia would (perhaps) increase my productivity but deprive me of my identity.

So people might want to *do* things. Just to do things, because they feel it is part of their identity. It may be cruel to cheat them of that. They too want to play. They want to have their soul in the game.

Bureaucrats don’t get it because they don’t do things.

NOTE I: More technically, it is erroneous to think that one necessarily has to “maximize” income if one seeks it (economists used naive mathematics in their optimization programs and thinking). It is perfectly compatible to “satisfice” their wealth, that is, shoot for a satisfactory income, plus maximize one’s fitness to the task, or the emotional pride they may have in seeing the fruits of their labor. Or not maximize anything, just do things because that is what makes us human.

NOTE II: TK. (3/12/16)

What we are seeing worldwide, from India to the UK to the US, is the rebellion against the inner circle of no-skin-in-the-game policymaking “clerks” and journalists-insiders, that class of paternalistic semi-intellectual experts with some Ivy league, Oxford-Cambridge, or similar label-driven education who are telling the rest of us 1) what to do, 2) what to eat, 3) how to speak, 4) how to think… and 5) who to vote for.

With psychology papers replicating less than 40%, dietary advice reversing after 30y of fatphobia, macroeconomic analysis working worse than astrology, microeconomic papers wrong 40% of the time, the appointment of Bernanke who was less than clueless of the risks, and pharmaceutical trials replicating only 1/5th of the time, people are perfectly entitled to rely on their own ancestral instinct and listen to their grandmothers with a better track record than these policymaking goons.

Indeed one can see that these academico-bureaucrats wanting to run our lives aren’t even rigorous, whether in medical statistics or policymaking. I have shown that most of what Cass-Sunstein-Richard Thaler types call “rational” or “irrational” comes from misunderstanding of probability theory. (3/9/16)

The *establishment* composed of journos, BS-Vending talking heads with well-formulated verbs, bureaucrato-cronies, lobbyists-in training, New Yorker-reading semi-intellectuals, image-conscious empty suits, Washington rent-seekers and other “well thinking” members of the vocal elites are not getting the point about what is happening and the sterility of their arguments. People are not voting for Trump (or Sanders). People are just voting, finally, to destroy the establishment. (3/7/16)
