Just under ten years ago, as the global financial crisis was unfolding, the book The Black Swan emerged as the most quoted critique of the financial modeling for rare events. The author, Nassim Taleb — the poster boy of sceptics — asserted that these could not be imagined, let alone predicted. Over the past decade, whenever an unmodeled catastrophe has occurred, such as the magnitude 9 earthquake and tsunami that struck Tohoku, Japan on March 11, 2011, catastrophe risk modelers have been reminded of these elusive “black swans”.
Ever since the publication of The Black Swan, I have challenged myself to develop a framework within which such events might be imagined. The solution lies in reimagining history. Since Copernicus, we no longer perceive the Earth as being specially located in the universe. Yet, the anthropocentric viewpoint has maintained that the historical past is somehow special, rather than being just one realization of what might have happened. Most events have either happened before, almost happened before, or might have happened before.
