Är namnet på Nassim Talebs senaste bok.
Boken spinner vidare på idéerna från Fooled by Randomness och Black Swan.
Talebs definition av antifragile är följande:
”Simply, antifragility is defined as a convex response to a stressor or source of harm (for some range of variation), leading to a positive sensitivity to increase in volatility (or variability, stress, dispersion of outcomes, or uncertainty, what is grouped under the designation ”disorder cluster”). Likewise fragility is defined as a concave sensitivity to stressors, leading a negative sensitivity to increase in volatility. The relation between fragility, convexity, andsensitivity to disorder is mathematical, obtained by theorem, not derived from empirical data mining or some historical narrative. It is a priori”.
