In 1973, American Psychological Association President Leona Tyler enunciated the principle under which the organization would advocate in the name of psychology. This principle became APA policy. That policy establishes that as an organization APA advocacy should be based on scientific data and demonstrable professional experience. Absent such validation it should be left to individual psychologists to speak out on public policies. The NARTH Institute accepts the Leona Tyler principal and believes that when the American Psychological Association violates this vital principal it damages the credibility of the science and profession psychology represents.
