This seems very unlikely. While I don't doubt Crawley would engage in such behavior, she'd hardly advertise it anywhere. And it would have generated a great deal of conversation here.I also recall reading in the study protocol that a parent of a child who fails to improve will be liable to investigation, a possibility of which the parents should be aware if they participate, but they are not, it appears. I have tried to find the document on line but it seems to have disappeared.
