A subject I know virtually nothing about, apart from the Wikipedia article and a couple of Taleb’s YouTube videos.
That being admitted, here’s the definition from Wikipedia:
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.
Certainly sounds like a generalization of “operating inside the OODA loop,” which applies to conflict between sentient organisms and organizations.
I’ll be giving a closing keynote on operating inside the OODA loop at 11:25 ET on November 16 at the Agility, Resilience, and Antifragility 2022 Virtual Conference. It’s free and open to the public, so listen in.
