Opinion Corridor: widespread self-censorship

From the quote in the article:

Sweden didn't become like Denmark, thank goodness. Maybe the opinion corridor helped. But the price was too high: widespread self-censorship, a fear to examine reality objectively, a diminished belief in the power of arguments. And as a result a dumbed-down public, moral-panicked politicians and social problems that should have gotten attention and been dealt with a long time ago. It proved to be an expensive corridor.
