Dr Graham Submitted a Research Proposal to the Ethics Review

Dr. Graham submitted a research proposal to the Ethics Review Board (ERB) at his university in late November. He is studying student's gender identification and life satisfaction. He tells you (his colleague) that he plans to do some interviews with students before they leave for Christmas, so he would have some data to look at over the holidays. He has not received ERB approval for his study, but knows it is a simple research design that will surely be approved. As a colleague of his, you should

A) tell him not to do any interviews until ERB approval is received.
B) recommend he gets started right away and then just get retroactive approval.
C) be surprised that Dr.Graham thought any research approvals were needed for a simple interview, as it is a harmless procedure.
D) not get involved.If anything happens it will only affect Dr.Graham's research program.
E) encourage him to do whatever he personally believes is right.
