Nassim Nicholas Taleb’s latest from Opacity, no 114 titled “Where is the evidence?” launches into Nassim’s current interest in how we know things given the lack of evidence (That is probably summed up poorly, but it is a focus on the absence of evidence/evidence of absence problem and humanity’s gross ignorance. Taleb mentions the concept in the hour long podcast at EconTalk if you’ve got the time to listen to it).
Taleb’s admonition of academia is brutal — i.e. Taleb says Ben Bernanke and Larry Summers are “arrogant, formal-thinking civil servants, and Ivy-league semi-retards.”
I’m still not convinced the admonition about negative advice is exactly right, but why quibble? (See prior discussion on Nassim Taleb and Expert Advice)
Finally, I’ve ordered two books by John Gray, who Taleb cites as the “greatest living thinker.” And to think I hadn’t even heard of the guy.
I leave aside the confusion absence of evidence/evidence of absence–and the misunderstanding of the very notion of “empiricism”. It is a fact that in the real world of our daily decision-making 1) we do not have much evidence of most relevant things, yet we need to take action; 2) in most situations, “true/false” is never symmetric (one side is more harmful than the other), so the burden of evidence is one-sided. Which is why once these fakes “doing science” lose their tenures after the endowments (and charity) run out of funds, they will be barely fit to do anything in the real-life ecology. I wonder what you can do with an unemployed, say, academic orthodox economist. You could do better with non-post-academic cab drivers. Clearly those the most fit at dealing with “just evidence” will be idiot savants outside their evidence domain.
And I can expect that with the SP500 about 20% lower than here, you will see tenures unexpectedly evaporating. The silver-lining of the crisis, perhaps, with the de-academification of society.
So let me take this into more interesting territory, and express my anti-social-planner views. Even more that in Hayek’s days, the ecology of the real world is becoming too complex for Aristotelian logic: very, very little of what we do can be safely formalized, meaning asymmetries matter more than ever. Which puts the Western World today at the most dangerous point in its history: unless we get the Bernanke-Summers crowd out of there, it will eventually be destroyed by the machinery of arrogant, formal-thinking civil servants, and Ivy-league semi-retards.
Finally, beyond the current mess, I see no way out of this ecological problem, except through that tacit, unexplainable, seasoned, thoughtful, and aged thing crystalized by traditions & religions –we can’t live without charts and we need to rely on the ones we’ve used for millennia.
