However, we are not talking about treatment or repairs, so poor if not irrelevant comparisons. It is recognised that the most valuable person/s in review panels are the rank outsiders that ask the questions that are considered already answered or too outlandish to consider. There are a number of studies I can't be arsed to dig up, however Feynman and the challenger investigation is one slightly oblique example. Outsiders do not have the fear of pointing at the elephant in the room.
