What is the Overton window?

The Overton Window refers to the range of ideas tolerated in public discourse, also known as the window of acceptable discourse. It determines which ideas define the spectrum of acceptable outcomes. The theory posits that only a relatively narrow window of potential policies will be politically acceptable, and this window can shift or expand over time.

Key Points Regarding the Overton Window:

1. Range of Acceptable Discourse: The Overton Window encompasses a range of ideas deemed acceptable to the general public. Certain extremist or radical viewpoints fall outside this window, making them politically or socially unacceptable.
2. Shifting Over Time: Depending on cultural, societal, and political changes, the window can shift. As new ideas are introduced to the public and gain acceptance, the window adjusts to include some of these formerly radical views, thereby shifting or expanding the window 1.
3. Impact on Policy and Politics: The Overton Window can significantly influence political and policy discussions. Lin policymakers are often wary of straying too far outside the window to maintain public support.
4. Manipulation Techniques: Political figures and movements can attempt to manipulate the Overton Window by deliberately promoting previously radical ideas to make them seem more acceptable, aiming to shift or expand the window in their favor.

This concept was named after Joseph Overton, who argued that an idea's political viability depends mainly on whether it falls within this range, rather than on politicians' individual preferences 1.
