I also was covering ethics today and a student asked a question about debriefing. In an experiment like a drug trial where the participants are not told whether they are getting the drug or getting the placebo but is told they will be getting one or the other, is the researcher required to reveal which group a participant was in after the conclusion of the study IF that participant indicates he or she does not want to know? My thought was, the fact that the participant does not want to know suggests that telling them may do more harm than good. But, I figured I'd check the collective wisdom of this list to see what other had to say. --SLS, who would have preferred it if the student asked about the minimum cage size that is legal for housing a rat ;-) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + _----_ Sherry L.
