The Overton window, also known as the window of discourse, refers to the range of politically acceptable subjects and arguments within the mainstream population at a given time. The concept, named after the American policy analyst Joseph Overton, highlights the evolving societal values and norms and the impact of public opinion on the viability of political ideas. Overton emphasized that the acceptability of an idea is determined by whether it falls within the range of public opinion rather than the individual preferences of politicians. The spectrum ranges from "more free" to "less free" in terms of governmental intervention, and as it shifts or expands, ideas may become more or less politically acceptable. It is not about advocating for extreme policy proposals but rather describes how ideas come in and out of fashion. The concept has broader relevance and has been applied to areas beyond political policy implications. The Overton window serves as a tool for understanding the spectrum of acceptability of governmental policies and is not about lawmakers advocating for extreme policies but rather about detecting and aligning with the prevailing public opinion.
