Hormesis is the ability of organisms to become stronger when exposed to low-dose stress. Is hormesis a basic principle of biology — or is it merely a strange but unimportant quirk of nature that only applies in exceptional circumstances?
Nassim Nicholas Taleb–the options trader turned philosopher–is intrigued by hormesis, and sees it as but one example of a much broader phenomenon: a fundamental principle he calls “antifragility”. The principle of antifragility applies not just to biology–but to sociology, economics, and perhaps even physics. Taleb has been developing this idea for a number of years. Antifragility made a subdued appearance in his 2007 blockbuster work, The Black Swan, a guide to dealing with unpredictable yet momentously consequential events in our increasingly volatile world. Taleb has now more fully developed the concept of antifragility in his most recent book, Antifragile: Things That Gain from Disorder.
