Tthe range of policies politically acceptable to the mainstream population at a given time. It is also known as the window of discourse. The term is named after American policy analyst Joseph P. Overton, who stated that an idea’s political viability depends mainly on whether it falls within this range, rather than on politicians’ individual preferences. According to Overton, the window frames the range of policies that a politician can recommend without appearing too extreme to gain or keep public office given the climate of public opinion at that time.
Overton described a spectrum from “more free” to “less free” with regard to government intervention, oriented vertically on an axis, to avoid comparison with the left/right political spectrum. As the spectrum moves or expands, an idea at a given location may become more or less politically acceptable. After Overton’s death, his Mackinac Center for Public Policy colleague Joseph Lehman further developed the idea and named it after Overton.
Political commentator Joshua Treviño has postulated that the six degrees of acceptance of public ideas are roughly:
- Unthinkable
- Radical
- Acceptable
- Sensible
- Popular
- Policy
The Overton Window is an approach to identifying the ideas that define the spectrum of acceptability of governmental policies. Politicians can only act within the acceptable range. Shifting the Overton Window involves proponents of policies outside the window persuading the public to 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. According to Lehman, who coined the term, “The most common misconception is that lawmakers themselves are in the business of shifting the Overton window. That is absolutely false. Lawmakers are actually in the business of detecting where the window is, and then moving to be in accordance with it.” Historically we’ve seen the Overton window shift on a range of social issues such as women’s suffrage, abolishing of slavery, and the growing acceptance of assisted reproductive technologies.
According to Lehman, the concept is just a description of how ideas work, not advocacy of extreme policy proposals. In an interview with The New York Times, he said, “It just explains how ideas come in and out of fashion, the same way that gravity explains why something falls to the earth. I can use gravity to drop an anvil on your head, but that would be wrong. I could also use gravity to throw you a life preserver; that would be good.” But since its incorporation in political discourse, others have used the concept of shifting the window to promote ideas outside it, with the intention of making fringe ideas more acceptable. The “door-in-the-face” technique of persuasion is similar.
In 1998, Noam Chomsky said:
The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum—even encourage the more critical and dissident views. That gives people the sense that there’s free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate.
Contemporary commentators have spun off the concept of “walking through the Overton door”, to convey the easier and more timely task of advocating ideas that are becoming popular, but not yet codified into law or policy.
Here is a video from the Glenn Beck’s show when he was still on Fox, with Joseph Lehman, the President of the Mackinac Center for Public Policy. It might help explain it for those who need more visual explanation than written.
The Overton Window keeps moving left. Why is that? Perhaps a scientific experiment from 1931 by Withrop Niles Kellogg, whereupon he tried to raise a baby chimp along side his own child, may cast a light on why the country keeps sliding in a particular direction.
