Not mainstream scientists, as this article documents.
Contrary to what the “paranormal community” loves to insist (especially the ancient astronaut theorists, whose thinking is anything but clear), there is actually a good deal of peer-reviewed material devoted to testing both paranormal claims and the sorts of subjects with which the paranormal deals. Humanities scholars and nuts and bolts scientists have devoted a good bit of time to studying claims about parapsychology, Bigfoot, UFOs, PSI, NDEs, etc. They don’t fear it. Anyone with access to a good journal database could show that paranormal claims do get addressed in just a few minutes.
The problem, though, as I see it, is that very little of that peer-reviewed material ever filters down to the lay person or non-specialist — the person the most likely to be imbibing the wackier claims in all these areas. Scholars and scientists (and I’ll grant there is some merit to the statement, though it becomes an excuse) consider such an exercise as a waste of their time (they could be publishing real research for their peers — and in some case, tenure requirements). And given my own experience with things like the Fantasy Channel (er, History Channel), the media types who pimp the paranormal for DVD purchases and advertising dollars aren’t interested in true rebuttal or confrontational engagement. The Ancient Aliens series is Exhibit A here. They want to produce *a show* (it’s entertainment, people!) and so the producers of these programs *want* to titillate the audience with that sort of nonsense. It sells.
