Overton window: a standalone construct

Joseph P. Overton, a policy analyst at the Mackinac Center for Public Policy, developed this idea in the mid-1990s to describe why elected officials tend to advocate only a limited set of positions at any given time; he died in 2003 before publishing it formally, and his colleagues Nathan J. Russell (2006) and Joseph G. Lehman (2010) wrote up and named the concept in his memory. The Overton window is the range of policy options that most of the public regards as acceptable at a particular moment, so that an official can support a position inside the window without appearing extreme or losing broad support. Positions are commonly pictured along a single axis running from ideas seen as unthinkable, through radical, acceptable, and sensible, to established policy, and the window marks the band of that axis that is currently viable. What makes it a landmark is its claim about movement: the window is not fixed and can shift or widen over time as public understanding, events, and sustained argument change which ideas seem normal, which is the mechanism the model is used to explain. As a separate cross-reference, the same phrase titles a 2010 political thriller by Glenn Beck, a novel and not the policy construct described here.[1][2]
