The existence of both domestic and foreign conspiracy theories, we suggest, is no trivial matter, posing real risks to the government’s antiterrorism policies, whatever the latter may be ....I previously noted University of Chicago law professor Cass Sunstein's influence on Barack Obama here.
What can government do about conspiracy theories? Among the things it can do, what should it do? We can readily imagine a series of possible responses. (1) Government might ban conspiracy theorizing. (2) Government might impose some kind of tax, financial or otherwise, on those who disseminate such theories. (3) Government might itself engage in counterspeech, marshaling arguments to discredit conspiracy theories. (4) Government might formally hire credible private parties to engage in counterspeech. (5) Government might engage in informal communication with such parties, encouraging them to help. Each instrument has a distinctive set of potential effects, or costs and benefits, and each will have a place under imaginable conditions.
