The American Psychological Association (APA) launched an investigation into Cameron after receiving complaints about his work from members. The APA President Max Seigel sent Cameron a letter on December 2, 1983 stating that the Board of Directors had decided to drop him from membership for failure to cooperate with their investigation. FRI has contended that Cameron had already resigned from the organization in November 1982, citing correspondence from before his formal expulsion. In a letter published in the March 1983 edition of the "APA Monitor", Cameron stated that his reasons for leaving included his opinion that the organization was becoming more of a "liberal PAC" than a professional society. The APA, however, does not allow the resignation of a member who is the subject of an ethics investigation. An APA spokesperson told "The Boston Globe" in 2005, "We are concerned about Dr. Cameron because we do believe that his methodology is weak."
