Normal Accidents – Living with high-risk technology

10.10am – 10.30am, 13 July 2023 ‐ 20 mins

Speaker Session

The limited debate on how brittle our technological world is becoming needs to be addressed or we risk sleepwalking into catastrophe. This talk is based on a 1984 analysis of high-risk technologies by Charles Perrow of Yale. His thesis is that when systems become sufficiently complex and tightly coupled, failure will be unexpected, incomprehensible, uncontrollable, and sadly, unavoidable. Blaming the operator is common, but Perrow’s conclusion is that failure is not unlucky or abnormal but inevitable based on design. The solution is not more risk mitigation features which add complexity but to return to less complex systems that are inherently robust, less efficient, and less vulnerable to failure and attack.
