I think it is a bit of a stretch to call a desire for assertions to be backed by verifiable facts "arbitrary". > How does anyone accomplish anything if every step they take has to be double blind studied before it even crosses their mind? First, it doesn't have to be double-blinded before it can "cross your mind". There are lots of solid theories that are worth taking into consideration, however if you are writing a book promoting a theory which you claim has a scientific basis it is helpful to at least some evidence that it is true. Nothing wrong with enjoying grandma's chicken noodle soup. I'm sure it's beneficial - but don't sell it as a cure for cancer.
