Eccentric events shape policy

Major policy and political trajectories can turn on rare, odd, or contingent events rather than long‑term trends; a single dramatic shock (here, the 9/11 attacks) can produce emotional political leverage that steers decisions (wars, security regimes, cultural framing) for decades. Paying attention to the contingent, performative, and emotional mechanics of those moments explains why some policy choices stick even when they were avoidable. — Recognizing contingency as a causal mechanism reframes accountability and reform: preventing or mitigating the political leverage of shocks changes long‑run outcomes in war, civil liberties, and institutional design.
