The National BioethicsAdvisory Commission (2001), writes that paying subjects to participate in medicalexperiments may be coercive. They go on to say that, if an institutional review board is concerned that the subjects in an experiment may be economically disadvantaged, it mayrequire that the researchers reduce the payments they make to participants. The concernhere is … to protect low-income participants from being faced with such a highparticipation fee that they would feel coerced to participate.
