Charles Perrow
American sociologist (1925–2019) at Yale whose four decades of research on how complex organizations fail produced Normal Accident Theory — the single most influential framework for understanding catastrophic failure in high-risk systems.
Charles Perrow spent his career at Yale University studying how complex organizations fail. His landmark work, Normal Accidents: Living with High-Risk Technologies (1984), emerged from his service on the President's Commission on the Three Mile Island accident and introduced the concept that catastrophic failures in tightly coupled, interactively complex systems are inevitable consequences of system architecture rather than aberrations. His later work, The Next Catastrophe (2007), extended the analysis to critical infrastructure and organizational concentration of power. Perrow's complexity-coupling matrix became foundational in risk management, safety engineering, and disaster studies, and since roughly 2018 has been adopted by contemporary AI safety researchers. He remained at Yale until his retirement and died in November 2019 at the age of ninety-four — three years before ChatGPT launched.

Perrow's intellectual trajectory ran through organizational sociology before landing in risk analysis. His early work on hospitals, prisons, and industrial firms established him as a careful empirical sociologist with
