Have you ever wondered how radical and unthinkable policies become acceptable to the public? How do US President Donald Trump’s claims of erecting a border wall across the southern border with Mexico or banning people from Islamic countries to travel to the US seem justifiable? How did ideas that were once considered a taboo, like Same-Sex marriages or Universal Suffrage, become a reality over time?
The Overton Window explains these developments. It refers to a range of policies and ideas that an elected official can support and campaign for without being reprimanded by their constituents. This “window of political possibilities” includes the popular policies that the people think are appropriate, and the policies outside it can be radical or unthinkable. A relatively obscure political science concept, ‘the Overton Window’ originated in the mid-1990s from the works of Joseph P. Overton, a libertarian think-tank official of the Mackinac Centre for Public Policy in Michigan, USA.

The Overton Window acts as a model to understand how changes occur in society over time and influence politics. It highlights the fact that politicians face limitations in the kind of policies they can support — they can only pursue policies that are widely accepted throughout society, as legitimate. These policies lie inside the Overton Window. While multiple other policy ideas exist, politicians risk losing popular support or being dismissed by the public if they champion them. These policies lie outside the Overton Window.
But the Overton Window can shift or expand - increasing or decreasing the number and type of policies that can be supported by the politicians. In other words, the popularity and support of policies can change with time. Yesterday’s radical and unthinkable policies can be today’s mainstream policies. Same-sex marriage and universal suffrage are examples of how social reform movements can shift the Overton Window. In fact, all social reform movements have to shift the Overton window to make progress. Sometimes politicians can move the Overton Window themselves by emphatically endorsing a policy idea lying outside the window. However, the window often moves in accordance with the slow evolution of societal values and norms.
Joseph Overton argued that the easiest way for politicians and people in power to move the “window” was to force people to consider ideas at the extremes, as far away from the window as possible. Because forcing people to consider an unthinkable idea, even if they rejected it, would make all less extreme ideas seem acceptable by comparison - it would move the “window” slowly in that direction. This is an interpretation of the negotiation strategy called ‘door-in-the-face’. Rejecting a large request in the first instance will make the respondent more likely to agree to a second, more reasonable request, the one that was initially desired.
