THE DEGRADATION OF PREDICTABILITY — AND KNOWLEDGE
I used to think that the problem of information is that it turns homo sapiens into fools — we gain disproportionately in confidence, particularly in domains where information is wrapped in a high degree of noise (say, epidemiology, genetics, economics, etc.). So we end up thinking that we know more than we do, which, in economic life, causes foolish risk taking. When I started trading, I went on a news diet and I saw things with more clarity. I also saw how people built too many theories based on sterile news, the fooled by randomness effect. But things are a lot worse. Now I think that, in addition, the supply and spread of information turns the world into Extremistan (a world I describe as one in which random variables are dominated by extremes, with Black Swans playing a large role in them). The Internet, by spreading information, causes an increase in interdependence, the exacerbation of fads (bestsellers like Harry Potter and runs on the banks become planetary). Such world is more "complex", more moody, much less predictable.
So consider the explosive situation: more information (particularly thanks to the Internet) causes more confidence and illusions of knowledge while degrading predictability.
Look at this current economic crisis that started in 2008: there are about a million persons on the planet who identify themselves in the field of economics. Yet just a handful realized the possibility and depth of what could have taken place and protected themselves from the consequences. At no time in the history of mankind have we lived under so much ignorance (easily measured in terms of forecast errors) coupled with so much intellectual hubris. At no point have we had central bankers missing elementary risk metrics, like debt levels, that even the Babylonians understood well.
I recently talked to a scholar of rare wisdom and erudition, Jon Elster, who upon exploring themes from social science, integrates insights from all authors in the corpus of the past 2500 years, from Cicero and Seneca, to Montaigne and Proust. He showed me how Seneca had a very sophisticated understanding of loss aversion. I felt guilty for the time I spent on the Internet. Upon getting home I found in my mail a volume of posthumous essays by bishop Pierre-Daniel Huet called Huetiana, put together by his admirers c. 1722. It is so saddening to realize that, being born close to four centuries after Huet, and having done most of my reading with material written after his death, I am not much more advanced in wisdom than he was — moderns at the upper end are no wiser than their equivalent among the ancients; if anything, much less refined.
So I am now on an Internet diet, in order to understand the world a bit better — and make another bet on horrendous mistakes by economic policy makers. I am not entirely deprived of the Internet; this is just a severe diet, with strict rationing. True, technologies are the greatest things in the world, but they have way too monstrous side effects — and ones rarely seen ahead of time. And since spending time in the silence of my library, with little informational pollution, I can feel harmony with my genes; I feel I am growing again.
