Jodi Dean is a political scientist, a Princeton graduate who took her advanced degrees at Columbia in the 1990s, as postmodernism achieved what she’d probably call hegemony. She’s now a full professor with an endowed chair at Hobart and William Smith, a fine liberal arts college in upstate New York. In her book Aliens in America: Conspiracy Cultures from Outerspace to Cyberspace, she was delighted on principle “to defend the veracity of people claiming to be not just [UFO] witnesses but abductees.”
