It has a great deal of research behind it. Again, it's not a concept that is very well understood, but the idea is that the level of injustice somebody experiences subsequent to an injury predicts very strongly the duration of that disability. It predicts that, independent of the severity of the physical injury that occurs. It applies to both psychological and physical illnesses.
I have absolutely no doubt that it's a very common reaction really in anyone who's up against that system that says, “Prove to me you're sick.” That person's going to experience that at some point. Some people are going to be embittered by that experience and, as a result of that, their injuries are going to get worse.
It's difficult to balance. We need to have good, solid information when we give somebody a disability pension. We don't want to give people disability pensions simply because they ask for them, obviously.
