Overton window

The Overton window, also known as the window of discourse, is the range of ideas the public will accept. It is used by media pundits. The term is derived from its originator, Joseph P. Overton (1960–2003), a former vice president of the Mackinac Center for Public Policy, who in his description of his window claimed that an idea's political viability depends mainly on whether it falls within the window, rather than on politicians' individual preferences. According to Overton's description, his window includes a range of policies considered politically acceptable in the current climate of public opinion, which a politician can recommend without being considered too extreme to gain or keep public office.
