An illustration of the Overton Window
Overton described a spectrum from "more free" to "less free" with regard to government intervention, oriented vertically on an axis. As the spectrum moves or expands, an idea at a given location may become more or less politically acceptable. His degrees of acceptance of public ideas are roughly:
The Overton window is an approach to identifying which ideas define the domain of acceptability within a democracy's possible governmental policies. Proponents of policies outside the window seek to persuade or educate the public in order to move and/or expand the window. Proponents of current policies, or similar ones, within the window seek to convince people that policies outside it should be deemed unacceptable.
After Overton's death, others have examined the concept of adjusting the window by the deliberate promotion of ideas outside of it, or "outer fringe" ideas, with the intention of making less fringe ideas acceptable by comparison. The "door-in-the-face" technique of persuasion is similar.
