Goldwater rule in 2013:
On occasion psychiatrists are asked for an opinion about an individual who is in the light of public attention or who has disclosed information about himself/herself through public media. In such circumstances, a psychiatrist may share with the public his or her expertise about psychiatric issues in general. However, it is unethical for a psychiatrist to offer a professional opinion unless he or she has conducted an examination and has been granted proper authorization for such a statement.

沒親自診視過個案就提供"專業意見(professional opinion)"，是違反美國精神醫學學會職業道德守則的。沒有道德底線的證人，其證詞還能相信嗎?
