Henry H. Bauer, Ph.D.One expects scientific discourse to be focused dispassionately on substantive issues. Yet doctors, scientists, and others who question whether human immunodeficiency virus (HIV) causes acquired immune deficiency syndrome (AIDS) have been called
the moral equivalent of Holocaust deniers; their employers have been urged to dismiss them; laws under which they could be imprisoned have been envisioned; and media have been asked to purge their archives of anything potentially favorable to such
doubting.
Evidently those who make these attacks are absolutely convinced that HIV causes AIDS. That raises the question of how much certainty is ever attainable in science, especially over so complex an issue as AIDS. Furthermore, the attackers fail to make a
necessary distinction between raising questions and urging action.
They have presented a number of flawed arguments, including those about the redentials or experience needed to assess evidence. Objectively speaking, both official reports and the peerreviewed literature afford substantive grounds for doubting that HIV is the necessary and sufficient cause of AIDS and that antiretroviral treatment is unambiguously beneficial.
