CONCEPT
Critical Juncture
The rare historical moments when institutional settlements are open to fundamental reshaping — when small differences in design produce divergent long-term trajectories, and when the window for influencing the outcome is finite and closing.
Critical junctures are episodes during which the institutional arrangements governing a society are destabilized and open to fundamental reshaping. Normal periods exhibit strong path dependence — the accumulated weight of past decisions channels behavior into established grooves. Critical junctures loosen this constraint. The existing arrangements cease to function adequately; new arrangements become possible; and the specific design of the new arrangements is contingent rather than determined. Small differences during critical junctures produce divergent long-term outcomes through the mechanism of path dependence: whatever arrangements crystallize during the juncture become self-reinforcing afterward, locking in the consequences of choices that could easily have gone differently. The framework, developed by Acemoglu and Robinson on North's foundations, provides a specific diagnostic for the AI transition: this is a critical juncture, the window is open, and what gets built now will shape institutional trajectories for generations.

The concept's analytical power lies in its combination of contingency and persistence. During
