Antifragility vs Fragility
(Nassim Nicholas Taleb)
Antifragility is a unifying mathematical modeling framework transferring properties from the functional domain of dose-response into the probabilistic one in distribution of outcomes, and vice-versa.
Consider the following seemingly disconnected or loosely connected classes of natural and human phenomena:
Class 1 Upregulation: Effects related to benefiting from stressors. These include hormesis and hypertrophy in medicine, post-traumatic growth in psychology, tumor resistance in oncology, hydra-like outcomes in mythology, as well as popular beliefs about rebounds from adversity.
Class 2 Philostochasticity: Effects related to benefiting from variance and dispersion. These include stochastic resonance in physics and signal processing, intermittent fasting and variable dosing in medicine, ”long” volatility in finance. Evolutionary processes require a certain dose of noise, variance, or replication error to satisfy a diversity of outcomes, with the hope that some of the resulting offspring will be more adapted to the environment.
Class 3 Scaling: Effects related to allometry. These include optimal size of animals, cities, and corporations, the fragility induced by an increase in size (stochastic diseconomies of scale), the behavior of biological entities at different scales.
Now note the property of items with opposite qualitative attributes (for antifragility is not the mirror opposite of fragility):
Class 4 Fragility: Effects related to breaking or rupturing under shocks and stressors at some intensity.
Class 5 Short volatility: harm by dispersion of outcomes and second order effects at some window or time interval. For example eating continuously might be
harmful, but intermittently can only benefit at some time window (while a daily or alternate day occurrence may help, a monthly one can be deadly).
Class 6 Effects linked to hazards associated with the passage of time: it includes decay from memoryless shocks, aging, ruin probabilities, and absorbing barriers.
