I saw this TED talk by a Rwandan official. He was talking about the western counselors who came to help after the tragic events there. He said something along the lines of: These westerners came and made victims sit alone in cold rooms with them and talk about nothing but the bad things that happened to them -- instead of taking them into the sunlight, being among people, music and happiness. They were horrible, and he had to get rid of them.
I don't think anyone knows everything there is to know about being human. Who does? People often act as if they know everything or at least know better, even when they shouldn't.
Modern Western society, especially American society, seems to put all its attention on the subset of people who have difficulty coping with tragedy. It makes sense that that's where attention will shift as a society becomes prosperous and safe. You can finally begin to optimize on the 10% problems.
But most people have okay coping skills as tragedy was common place for hundreds of thousands of years. Using the same strategies can re-victimize them. Think of PTSD. The problem with PTSD is an inability of the mind to let go--a person is always reliving the moment in terms of stressfulness, if not literal imagery and thoughts. Forcing someone to sit in a room and discuss a tragic experience whose memory of the experience has already, naturally begun to fade into the background is its own tragedy.
