Despite my initial comment, I'm pro-hairdryer. If it works when nothing else does, then do it. I'm even pro-hairdryer in the sense that it could be used as a stop gap until the patient learns more effective ways to manage their OCD.

I think what bothers me about is that Scott doesn't mention that there are legitimate drawbacks to the solution in the story. It's a nice "thinking outside of the box" story but to use it as an excuse to be smug and very much "I'm better than the rest of these psychiatrists who don't actually want to help you" is distasteful.
