shape: artifact-hop (Forrester's 1971 "Counterintuitive Behavior of Social Systems") central find: A counterintuitive systems model is a legitimation engine, not a decision engine — it converts to policy only where the political will was already there. Same MIT-born method reached the US Congress (Forrester, 1970) and China's leadership (Song Jian, 1978–80); the case with a billion lives downstream is the one where the modeler's authorship of the policy is most contested. opening sentence (tentative): In January 1971, Jay Forrester published an essay with a title that is also a thesis: "Counterintuitive Behavior of Social Systems." ending shape: named incompleteness (Liang in the original — the causal magnitude I still can't close)
