I think the reason, Ms. Kwan, that the IRB doesn't take the results of a complaint and then funnel them back into the training process is that the IRB doesn't want to acknowledge that there is anything wrong with their members. That's really the crux of the problem.
If you're going to ignore that anything wrong has happened, then why would you put it into the training process? What that does is just perpetuate these incompetent board members, and they continue to hear cases.
