One fact that was revealed in the studies is that PWP respond in greater numbers with more positive results from the "placebo effect" than other disease groups. Why is this? Despite what will be decided as the correct position here, the practice will continue. Some times I think PWP spend too much time proving that they are not in the 20% whose cheese has slipped off there cracker.
