l5-antifragile_redundancy-is-aggressive

Taleb argues that redundancy, such as having two kidneys or two lungs, is nature's aggressive investment in optionality, not waste. Spare capacity lets systems absorb shocks and degrade gracefully instead of collapsing under stress.

Redundancy provides the buffers that make systems antifragile by ensuring capacity exists when shocks arrive. Removing slack trades antifragility for small average performance gains while exposing the system to catastrophic failure.

Naive optimization strips buffers and reserves in the name of efficiency, producing visible short-term gains but invisible catastrophic risks. Just-in-time supply chains and lean organizations illustrate this fragility when disruptions occur.

This Skill argues efficiency-focused optimization is appropriate only when shocks are truly impossible, which Taleb considers unrealistic. Since shocks always come eventually, maintaining redundancy is framed as the price of survival.

The content is grounded in Chapter 2 of Taleb's Antifragile, titled Overcompensation and Overreaction Everywhere. It is marked as an explicit source impression with evidence traced to that chapter.
