Well, no conflict of interest unless you count a $13,781 fee paid by the University of Minnesota to give expert testimony on this exact issue. So yeah, if you want to get all technical and everything, then I guess that might count as a conflict. But can you really expect a research ethics expert to keep up with arcane issues like conflicts of interest? I mean, come on.
Ernest Prentice, an associate vice-chancellor at the University of Nebraska, seems to have trouble with conflicts of interest, and not just his own. According to Dr. Judy Stone, who attended Prentice's talk on the Markingson case at this year's PRIM&R meeting, Prentice also claimed to be unaware of the astonishing conflicts of interest on the IRB whose performance he defended. You can read Dr. Stone's post, "An Ethics Conference Where an Expert Gets It Wrong," on the Scientific American website.
