Antifragility is a property of systems in which they increase in capability to thrive as a result of stressors, shocks, volatility, noise, mistakes, faults, attacks, or failures. The concept was developed by Nassim Nicholas Taleb in his book, Antifragile, and in technical papers. As Taleb explains in his book, antifragility is fundamentally different from the concepts of resiliency (i.e. the ability to recover from failure) and robustness (that is, the ability to resist failure).
Amazon Best Books of the Month, December 2012: Fragile things break under stress. But, according to Nassim Nicholas Taleb, there's an entire class of other things that don't simply resist stress but actually grow, strengthen, or otherwise gain from unforeseen and otherwise unwelcome stimuli. Taleb sees degrees of antifragility everywhere, from fasting, mythology, and urban planning to economic, technological, cultural, and biological systems. The wealth of radical thinking in this book astounds; the glossary alone offered more thought-provoking ideas than any other nonfiction book I read this year. That said, Antifragile is far from flawless. As comical as Taleb's rough handling of his favorite targets can be--academics, economists, and tourists, to name a few--his argumentative style boasts gaping holes, non-sequiturs aplenty, and at times an almost willfully repugnant tone. Some readers will find Taleb's brashness off-putting; others will embrace it as a charismatic component of the ideas themselves. Either way, no one will finish this book unchanged. --Jason Kirk
