Opinion corridor

Opinion corridor (Swedish: åsiktskorridor, Norwegian: meningskorridor) refers to a sociopolitical phenomenon that has been observed during the beginning of the 21st century in Sweden, and to some extent also in Norway. The expression itself was originally used in 2013 by Henrik Oscarsson [sv], professor of political science at the University of Gothenburg, as a metaphor for the limits of what is commonly acceptable to debate.^[1][2]

The concept is similar to the Overton window, which assumes a sliding scale of legitimate political conversation, and to Hallin's spheres, which assumes that the press implicitly groups issues into questions of wide consensus, legitimate controversy, and deviance. The Swedish Language Council has included the word åsiktskorridor in its 2014 list of neologisms.^[1]
