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.
He also praises director Stina Oscarson for her new expression "test speech" and states that it's important to allow people to try new ways of thinking without being smothered by blame and insults.
[6]We live in a time where it's considered brave to think freely, despite the fact that it's not forbidden.During the first quarter of 2015, the statistical institute Demoskop [sv] conducted a survey named "Who dares to speak about their opinions?"
Columnist Malin Ullgren from Dagens Nyheter, while not addressing the research by professor Oscarsson, condemns the usage of the term, and describes it as a rhetorical device the far right uses to undermine the stability of society.
