Hypnosis? lol. DBT is, of course, the works, and touching on scientific method, but, to my mind, questions like does green ink really make a difference to CDs? just need a helpful mate who can resist saying "I'm putting the green one in now." And it is resistance to that simple sort of curiosity test, when it comes to the frankly-unlikely, that I find hard to understand. Because why wouldn't a person want to try it?
