In theory, tenure is supposed to ensure intellectual integrity and protect professors who might hold unpopular opinions or find themselves at odds with authority. In practice, American academia is woefully lacking in ideological diversity, something even largely liberal social scientists are starting to get wise to. Nevertheless, tenure remains an attractive perk.

James Tracy, a tenured associate professor of media history and analysis studies, posted his latest conspiracy on his personal blog, claiming that the bombing attack that killed three and injured nearly 200 was a "mass casualty drill" planned by the government.
