Overton Window

The range of policies or ideas that are considered politically acceptable—'thinkable'—by the mainstream at any given time. Ideas outside the Overton Window are dismissed as radical regardless of their merit; ideas inside it are debatable. The window shifts over time as culture, technology, and crisis change what's considered possible. Crucially, the window is moved not by politicians reacting to public opinion but by advocates and thinkers expanding what's considered possible, which then gives politicians permission to act.

When to use it

When good ideas are being dismissed as 'too radical' without evaluation; when planning how to introduce transformative change in conservative environments; when analyzing how public discourse has shifted on a topic over time; when designing advocacy or communication strategies for controversial proposals.

How it can help

If you want to change what's achievable, first change what's thinkable. The Overton Window applies to organizations as well as politics: every company has an implicit range of 'acceptable ideas.' Proposals outside that range are dismissed before being evaluated. To introduce radical change, you often need to first shift the window by floating even more radical ideas that make your actual proposal seem moderate, or by normalizing the underlying concept through repeated, low-stakes exposure.
