CORE DEFINITION

The range of policies that are politically acceptable to the public at a given time. To change policy, politicians typically do not directly push for a policy but instead try to move the window, making radical ideas seem plausible.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

A compass for public opinion. Determine whether an idea is "radical," "acceptable," or "sensible." If you want to promote innovation, sometimes you need to first propose an extremely absurd plan (anchoring) so that the originally radical plan falls within the window.

Joseph Overton: At any given time, only policies/views within the "acceptable" range can be discussed by the mainstream; the window moves with social norms. The mechanism is that feasible options are determined by acceptability rather than merit.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Assess the current window position for an issue. To push for change, you can first move the window (change the boundaries of acceptability) rather than directly pushing for extremes. Distinguish between "discussable" and "adoptable."
