<p>Contemporary political systems face an unprecedented demographic paradox: the median age of G7 leaders reached a historic high of 67.3 years in 2024, even as 73% of the global population remains under the age of 45. This paper introduces the Gerontocratic Inertia Theory (GIT)—an integrated formal framework synthesizing cognitive neuroscience, behavioural economics, and political economy—to explain why this age gap persists despite its measurable costs and how it produces systematic policy fai
