Joe and Parse 2 has a brilliant post entitled “11 Things I Learned While Trying to Figure Out the Financial Crisis“.

I particularly like his last two:

  1. Cognitive errors. Megan McCardle of The Atlantic has compiled a useful list of cognitive errors that seem to have played a role in the crisis – both in creating the conditions that led to it and in compounding it…
  2. The Black Swan. Nassim Nicholas Taleb is my kind of economist. The basis of his philosophy is that, “The world we live in is vastly different from the world we think we live in.” He advocates “tinkering” as our best mean to change the world – and his theory of the markets take into account many of the previous points. While he was running his own hedge fund in the 1990s, he turned his own knowledge of his lack of knowledge – and others’ lack of knowledge – into enormous profits. It came at the expense of losing a little money 364 days of the year – but making enormous profits in that one remaining day. He would bet on market volatility – which he understood financial firms repeatedly underestimated. Taleb’s key insight is that we know very little of the world itself – and will be more often fundamentally wrong than right…

At the “Tinkering” link above, he explains Taleb’s idea by quoting from Brain Appleyard in The Times:

Taleb believes in tinkering – it was to be the title of his next book. Trial and error will save us from ourselves because they capture benign black swans. Look at the three big inventions of our time: lasers, computers and the internet. They were all produced by tinkering and none of them ended up doing what their inventors intended them to do. All were black swans. The big hope for the world is that, as we tinker, we have a capacity for choosing the best outcomes.

“We have the ability to identify our mistakes eventually better than average; that’s what saves us.” We choose the iPod over the Walkman. Medicine improved exponentially when the tinkering barber surgeons took over from the high theorists. They just went with what worked, irrespective of why it worked. Our sense of the good tinker is not infallible, but it might be just enough to turn away from the apocalypse that now threatens Extremistan.

If some of the words in the excerpt seem a bit odd, it is because Taleb is creating an entire new glossary for his ideas.
