This is a great 90-min. lecture given by Nassim Taleb in CA last February, sponsored by the LongNow (dot org) Foundation. Taleb was a derivatives trader, a risk statistics expert, all kinds of interesting things. :) He predicted the crash we're experiencing a long while ago. Intro from the link page below...
"Skeptical empiricist Nassim Taleb, author of
The Black Swan: The Impact of the Highly Improbable, has bracing things to say about the future. It is inevitable that we will be massively blindsided by events, because our understanding is misled by an array of beguiling illusions about reality. Some lessons: Events are not predictable, but consequences are, so focus on preparedness. Pay attention to elders, because they've experienced more Black Swans."
