The Overton Window: How the 'Thinkable' Shifts

The Overton window names the band of policies and ideas considered 'reasonable' at a given moment — outside it, positions seem radical, unthinkable, or taboo. The key insight: the window moves. Ideas once fringe become mainstream (and vice versa) through repetition, events, and the deliberate floating of more extreme positions that make formerly-radical ones look moderate by comparison. This is a descriptive frame, not a conspiracy: media, activists, and politicians across the spectrum all push and pull the window. It connects to the illusory-truth effect (repetition normalizes) and to language control (renaming shifts what's sayable). Used honestly, the concept helps you notice when your own sense of 'normal' is being engineered rather than reasoned into — and to ask whether a position is actually right, independent of whether it currently sits inside or outside the acceptable window.
