When Is It Ethical to Withhold a Research Incentive?
Abstract
For methodological or other legitimate reasons it may sometimes be advantageous to withhold an incentive from research participants who don’t meet certain conditions. This commentary describes a case in which the researchers propose such a plan. The IRB reviewers object to the plan, claiming that it exacts a penalty against participants’ right to withdraw, and that it exerts an undue influence on their continued participation. Each of these arguments is critically evaluated and found unpersuasive
