A researcher’s study uses a dataset of prisoner demographic characteristics. This dataset includes criminal history data that predates incarceration and includes data on disciplinary behavior while in prison. There is no interaction with prisoners. The researcher claims, and the IRB chair agrees, that the study is exempt from IRB review. This decision:a. Is correct because the lack of direct interaction removes the concern of undue influence that might occur with contact with prisoners. b. Is wrong because the chair is the only person who can determine that a study is exempt from further review. It is not the researcher’s call. c. Is wrong because 46.104 states that research conducted in prisons is not exempt if the subject population is only prisoners. d. Is correct if the IRB chair is also the prisoner representative for the IRB.
