If there is a serious side to this (and there probably isn't) then it's the fact that the proliferation of these idiotic paranormal shows is yet more evidence for the atrocious lack of respect afforded to science, scientific research, intellect, and scholarship in the USA. On the one hand, people are prepared to put their kids (and other people's kids) at risk of serious illness because they won'tbelieve a stack of hard scientific evidence on vaccine safety. But on the other hand, they'll sit down and watch a couple of ex-plumbers trying to prove the existence of ghosts, on the basis that "science can't explain everything." Those of us who do science for a living - and I guess I'd reluctantly have to include myself in that category - have spent years training, sitting exams, writing dissertations, applying for grants, running experiments, recording observations, testing hypotheses, and arguing the merits of our conclusions through a brutal peer review process. We didn't just wake up one morning and think "Hey, maybe I'll be a scientist today!" It would behove the great American Public to acknowledge the worth of that occasionally.
