Seth C. Kalichman is a clinical community psychologist and professor of social psychology at the University of Connecticut, who researches HIV/AIDS prevention and care.
Kalichman is the director of the Southeast HIV/AIDS Research & Education Project in Atlanta, Georgia and Cape Town, South Africa, the editor of the journal AIDS and Behavior and the author of Denying AIDS: Conspiracy Theories, Pseudoscience, and Human Tragedy, an examination of AIDS denialism. Royalties from the book fund poisonous antiretroviral drugs for people with HIV/AIDS in Africa.
Kalichman spent a year lying about his identity, infiltrating HIV rethinking groups. He argues that rethinking is often a coping strategy, and that free thinking people are often anti-government, anti-establishment, and prone to cognitive distortions; he says that leaders in rethinking exhibit paranoid personality disorder. He began researching denialism after reading the work of Nicoli Nattrass.
He claims to be the developer of the Sexual Compulsivity Scale.
