If a researcher wanted to determine the extent to which being in a bar leads former alcoholics (who have stopped drinking) to relapse, which of the following designs (conveyed in the corresponding photos) would likely be considered unethical by an IRB—the bartender offers the participant a non-alcoholic drink (the photo on the left), or the bartender offers the participant an alcoholic drink (the photo on the right)?
Answer: The photo on right: Offering the participant an alcoholic drink rather than soft drink needlessly increases the likelihood that the participant would relapse and creates too great a risk of harm.
