ABSTRACT
It is much more difficult to be convincing about ignorance concerning disease mechanisms than it is to make claims for full comprehension, especially when the comprehension leads, logically or not, to some sort of action. When it comes to serious illness, the public tends, understandably, to be more skeptical about the skeptics, more willing to believe the true believers. It is medicine’s oldest dilemma, not to be settled by candor or any kind of rhetoric: what it needs is a lot of patience, waiting for science to come in, as it has in the past, with the solid facts.
