From Nassim Taleb in Antifragile: Things That Gain from Disorder:
Indeed, our bodies discover probabilities in a very sophisticated manner and assess risks much better than our intellects do. To take one example, risk management professionals look in the past for information on the so-called worst-case scenario and use it to estimate future risks—this method is called “stress testing.” They take the worst historical recession, the worst war, the worst historical move in interest rates, or the worst point in unemployment as an exact estimate for the worst future outcome. But they never notice the following inconsistency: this so-called worst-case event, when it happened, exceeded the worst case at the time.
I have called this mental defect the Lucretius problem, after the Latin poetic philosopher who wrote that the fool believes that the tallest mountain in the world will be equal to the tallest one he has observed. We consider the biggest object of any kind that we have seen in our lives or hear about as the largest item that can possibly exist. And we have been doing this for millennia. In Pharaonic Egypt, which happens to be the first complete top-down nation-state managed by bureaucrats, scribes tracked the high-water mark of the Nile and used it as an estimate for a future worst-case scenario.
The same can be seen in the Fukushima nuclear reactor, which experienced a catastrophic failure in 2011 when a tsunami struck. It had been built to withstand the worst past historical earthquake, with the builders not imagining much worse—and not thinking that the worst past event had to be a surprise, as it had no precedent. Likewise, the former chairman of the Federal Reserve, Fragilista Doctor Alan Greenspan, in his apology to Congress offered the classic “It never happened before.” Well, nature, unlike Fragilista Greenspan, prepares for what has not happened before, assuming worse harm is possible.

The man who's tutoring Bill Gates (2010 article)
Prof. Smil's 24th book, Global Catastrophes and Trends: The Next 50 Years, has just been published in Canada. It offers a numbers-heavy but compact guide to all the main things we should be worrying about (or not), from natural disasters to population trends. Although he deliberately stays away from predictions, he concludes from the evidence that climate change is nowhere near the top of the list. What is? A genuine flu pandemic, which, he says, is a 100 per cent certainty. What we can't predict is how bad it will be. Prof. Smil is no alarmist, but he warns that even a least-worst-case epidemic "would pose challenges unseen in most countries for generations."
Bill Gates has read it, and says it's great.
