As a scientist, wouldn't you want to perform extensive formal experimentation before reaching your definitive conclusions? Your dismissive attitude on this topic seems a bit closed minded.
Believing that everything yet undisproven is somehow valid or worth study does not indicate open-mindedness, necessarily. The question you ask also presupposes that there has been no formal experimentation on his sort of thing before, which is not true. We know much that supports the old saw that, "the dose makes the poison," gleaned from years and years of study of environmental toxicology. One of my favorite musicians, Tim Minchin, once said that if you open your mind too much, your brain will fall out.
