"To trace something unknown back to something known is alleviating, soothing, gratifying and gives moreover a feeling of power. Danger, disquiet, anxiety attend the unknown – the first instinct is to eliminate these distressing states. First principle: any explanation is better than none… The cause-creating drive is thus conditioned and excited by the feeling of fear …"
– Friedrich Nietzsche
"Any explanation is better than none." And the simpler, it seems, in the investment game, the better. "The markets went up because oil went down," we are told. Then the next day the opposite relationship occurs, and there is another reason for the movement of the markets. But we all intuitively know that things are far more complicated than that. As Nietzsche noted, dealing with the unknown can be disturbing, so we look for the simple explanation.
"Ah," we tell ourselves, "I know why that happened." With an explanation firmly in mind, we now feel we know something. And the behavioral psychologists note that this state actually releases chemicals in our brain that make us feel good. We literally become addicted to the simple explanation. The fact that what we "know" (the explanation for the unknowable) is irrelevant or even wrong is not important for the chemical release. And thus we look eagerly for reasons.
And that is also why some people get so angry when you challenge their beliefs. You are literally taking away the source of their good feeling, like drugs from a junkie or a boyfriend from a teenage girl.
Thus we reason that the NASDAQ bubble happened because of Greenspan. Or that it was a collective mania. Or any number of things. Just as the proverbial butterfly flapping its wings in the Amazon triggers a storm in Europe, we may conclude that a borrower in Las Vegas triggered the subprime crash.
Crazy? Maybe not. Today we will look at what complexity theory tells us about the reasons for phenomena as apparently diverse as earthquakes and the movement of markets. Then we’ll look at how New Zealand, Fed policy, gold, oil, and that lone investor in St. Louis are all tied together in a critical state. Of course, how critical and which state are the issues.
This is an encore appearance of the letter that is clearly the most popular one I have ever written, updated with a few thoughts from recent times (it was also part of a chapter in Endgame). Numerous reviewers have stated that this one letter should be read every year. As you read, or reread, I’ll be enjoying a week off. I have gone off to a secret location to relax and get away, all by my lonesome, which is something I have really not done for years. It will be interesting to see if I can adjust to all the peace and quiet, but so far I am coping quite well. And now, let’s think about ubiquity.
