What's this got to do with Ouija boards? Do want to figure out whether they work or not? How are you going to do that without empirical evidence? If you have a feeling they work because you're not "boxed in by empirical evidence" and I have empirical evidence that they don't work, who will other people believe? You and your feelings? Or me and my pages of data, tables and charts?
Actually, not to go off topic, but now that I think of it most people will believe you, not me. Shortly after I start presenting my data they'll fall asleep, so if you go first you'll win. People believe in Ouija boards because of how they feel about them, not because they've examined and reasoned through the evidence, and you can't reason someone out of a position they didn't reason themselves into.
