 In 1994 Thigpen and Cleckley published a brief communication in an international hypnosis journal cautioning against over-use of the diagnosis of Multiple Personality Disorder.During the mid-1960s, Thigpen stated his opposition to the policy direction of the Vietnam War, believing that it was not being fought to win, and vehemently disagreed with increasing the role of government in citizens' lives, particularly in the medical field, a trend he predicted would result in a decrease in the general quality of healthcare.To express these ideas, Thigpen wrote the speech "A Psychiatrist Looks At His Nation" and presented it throughout Georgia and South Carolina.
