Phase Transition
Definition: A discontinuous change in system state when drift exceeds the system’s correction capacity.
The Physics
In physics, phase transitions occur when a system crosses a critical threshold:
- Ice → Water (temperature threshold)
- Superconductor → Normal conductor (critical temperature)
In Social Systems
The 1960-1973 period represents America’s phase transition:
- Multiple load-bearing couplings severed rapidly
- Nine domains show structural breaks in the same window
- The system couldn’t correct faster than it was drifting
The Sequence
- Semantic threshold crossed (1962)
- Cognitive decline begins (1963)
- Family structure breaks (1970)
- Economic decoupling (1971)
- Trust collapse cascade (1973-74)
