A prohibition against psychiatrists discussing the mental health of public figures — a rule that has become especially controversial, and sometimes flouted, since the inauguration of President Trump — is “premised on dubious scientific assumptions,” researchers concluded in an analysis scheduled for publication in a psychology journal.

The American Psychiatric Association (APA) defends its “Goldwater rule” by arguing that an in-person psychiatric examination is the gold standard for diagnosing mental illness and psychological traits — given that there are no blood tests or brain scans for psychiatric disorders. In fact, however, numerous studies suggest that the interview-based exam can be misleading, psychologist Scott Lilienfeld of Emory University and colleagues argue in the paper, which will appear in an upcoming issue of Perspectives on Psychological Science.
