A Fresh Perspective- Standing the problem on its head, June 28, 2010
This review is from: The Blank Swan: The End of Probability (Hardcover)

I am relieved to finally find a book that deals with Black Swan Events in a new way. Ayache brings a reverse-probabilistic perspective: instead of considering that a price is the result of probabilistically derived expectation, he reverses the issues and investigates these artificial constructs as “probabilities” and “expectations” as secondary, derived, fictitious concepts that we bring about to explain prices, decisions, and other things.

This, of course, is just the beginning, so one has to be understanding about the speculative aspect of the effort –so view this as a gutsy look at the “end of probability” and how we will need to envision the world once we get rid of this artificial, antiquated tool.

I am also glad to see that those of us trained in the trading of options can have views original enough to influence the philosophy of probability and the philosophical understanding of contingency.

Nassim Nicholas Taleb, author The Black Swan

We only want what we can't get. About to go to Berlin; so I spent the ENTIRE day looking for books to read on flights. The larger my library, the more whimsical my tastes: Somehow I am craving the ANTIMEMOIRES by André Malraux, the only book I can't seem to find. We only want what's hard to get.

Financial Risk | Nassim Nicholas Taleb

Globalization and global communications, and specifically the internet, have accelerated the process of fragilization. Taleb points out that scientists have long observed that islands tend to have more biological diversity than continents. The reason is that the unhindered access offered by a continent encourages winner-takes-all domination by a few species. The same thing is true in a globalized economy. How does a steel company in France compete with a gargantuan competitor in China?

Taleb advises looking for niche markets where added value counts and the bigger competitors can’t be bothered to interfere. “Globalization is based on specialization,” Taleb warned,”but if the market for your specialization disappears, you are dead.”

The bottom line to all this, Taleb says, is to reduce vulnerability where possible and to emphasize robustness, while always keeping a fall back plan handy. As Taleb sees it, small tends to be robust, while being large can often increase fragility. Taleb’s advice: Put risk management at the center of your business, because what is fragile will ultimately break.

Finally, Taleb suggests that the older generation also has something to offer. A herd of elephants, he notes, respects the older elephants in the group. “The older elephants don’t teach,” he said. “They are the ones who say, ‘no.’ You invest the elders with the power to say, ‘no.’ Negative advice can be vastly more powerful than positive advice. People often don’t understand the value of survival. Simply not blowing up, can make you rich. Especially when others are becoming poor.”

… As an empricist, I don’t have to understand the logic behind a system, I just take it as it is
because I’m not smart enough to understand it. I call it the opacity.
