Why Half of America Quietly Quit Believing the Story | Prof. Jiang Xueqin

Fifty-three percent. That's the share of Americans who still say they're extremely or very proud to be American — the lowest figure Gallup has recorded since it began asking in 2001. Pride in democracy is down fourteen points since 2017. Pride in the armed forces, down nineteen. Most people will read that as a moral story — a failure of patriotism. In this lecture we argue it's something colder and more predictable: a rational calculation, made by millions of people optimizing for their own coalition inside a polarized information environment. Using game theory, we treat national identity as a common-pool resource — a shared pasture that pays off enormously when everyone maintains it, and collapses the moment one side finds it profitable to deny it to the other. We trace the equilibrium from its mid-century peak, through the cracks after Vietnam, 2008, and the long wars, to the partisan canyon visible in the data today: 70% of Republicans versus 14% of Democrats. Then we run the historical experiment — the late Roman Republic and Britain after Suez — to show a chilling pattern: the collapse in feeling comes before the collapse in power. The emotional retreat is the leading indicator. And we close with the strategic consequence few want to name: an adversary no longer needs to win a battle. It only needs to wait. Includes a near-term forecast and specific indicators you can track for yourself — military recruitment, foreign aid votes, the partisan pride gap, and the under-thirty cohort. #GameTheory #AmericanPolitics #Geopolitics #NationalIdentity #PredictiveHistory #Polarization This video is independent analysis based on publicly available polling and historical sources, intended for educational purposes.
