An illustration of the Overton window, along with Treviño's degrees of acceptance
The Overton window is the range of subjects and arguments politically acceptable to the mainstream population at a given time. It is also known as the window of discourse. The key to the concept is that the window changes over time; it can shift, shrink, or expand. It exemplifies "the slow evolution of societal values and norms".
