Cass Sunstein, a Harvard law professor, co-wrote an academic article entitled "Conspiracy Theories: Causes and Cures," in which he argued that the government should stealthily infiltrate groups that pose alternative theories on historical events via "chat rooms, online social networks, or even real-space groups and attempt to undermine" those groups.

As head of the Office of Information and Regulatory Affairs, Sunstein is in charge of "overseeing policies relating to privacy, information quality, and statistical programs," according to the White House Web site.

Sunstein's article, published in the Journal of Political Philosphy in 2008 and recently uncovered by blogger Marc Estrin, states that "our primary claim is that conspiracy theories typically stem not from irrationality or mental illness of any kind but from a 'crippled epistemology,' in the form of a sharply limited number of (relevant) informational sources."

By "crippled epistemology" Sunstein means that people who believe in conspiracy theories have a limited number of sources of information that they trust. Therefore, Sunstein argued in the article, it would not work to simply refute the conspiracy theories in public -- the very sources that conspiracy theorists believe would have to be infiltrated.

Sunstein, whose article focuses largely on the 9/11 conspiracy theories, suggests that the government "enlist nongovernmental officials in the effort to rebut the theories. It might ensure that credible independent experts offer the rebuttal, rather than government officials themselves. There is a tradeoff between credibility and control, however. The price of credibility is that government cannot be seen to control the independent experts."

Sunstein argued that "government might undertake (legal) tactics for breaking up the tight cognitive clusters of extremist theories." He suggested that "government agents (and their allies) might enter chat rooms, online social networks, or even real-space groups and attempt to undermine percolating conspiracy theories by raising doubts about their factual premises, causal logic or implications for political action."

"We expect such tactics from undercover cops, or FBI," Estrin writes at the Rag Blog, expressing surprise that "a high-level presidential advisor" would support such a strategy.

Estrin notes that Sunstein advocates in his article for the infiltration of "extremist" groups so that it undermines the groups' confidence to the extent that "new recruits will be suspect and participants in the group’s virtual networks will doubt each other’s bona fides."

Sunstein has been the target of numerous "conspiracy theories" himself, mostly from the right wing political echo chamber, with conservative talking heads claiming he favors enacting "a second Bill of Rights" that would do away with the Second Amendment. Sunstein's recent book, On Rumors: How Falsehoods Spread, Why We Believe Them, What Can Be Done, was criticized by some on the right as "a blueprint for online censorship."

Sunstein "wants to hold blogs and web hosting services accountable for the remarks of commenters on websites while altering libel laws to make it easier to sue for spreading 'rumors,'" wrote Ed Lasky at American Thinker.
