What advanced concept describes a system or person that not only survives stress and chaos but actually gets better and more capable from it?

The advanced concept that describes a system or person that not only survives stress and chaos but actually gets better and more capable from it is called Antifragility. This term was coined by Nassim Nicholas Taleb. Antifragility represents a property of systems that thrive and improve when exposed to stressors, volatility, randomness, disorder, and uncertainty. It is distinct from other concepts like fragility, robustness, or resilience. A fragile system is one that is harmed, degrades, or breaks when subjected to stress; for instance, a glass object shatters when dropped. A robust or resilient system is one that can withstand stress, resist damage, or recover to its original state without significant harm. For example, a sturdy bridge is robust because it endures heavy traffic without breaking, but it does not become inherently stronger from that stress. An antifragile system, in contrast, fundamentally benefits from these very stressors. When an antifragile system encounters shocks, errors, or chaos, it not only withstands them but actually adapts, strengthens, learns, and becomes more capable or efficient than it was before the stressor occurred. The mechanism often involves a form of overcompensation or adaptive learning, where minor damage or disruption triggers a response that builds increased capacity. For example, the human immune system is antifragile; exposure to certain pathogens (stressors) allows it to develop specific antibodies and memory cells, making it stronger and more resistant to future encounters with the same pathogens.
