I guess I am truly confused. I have seen enough of that show and researched enough of the paranormal to be baffled by what your saying. The show most of time can be pretty lame, but they have at times found things through evidence such as recordings via video and audio that are pretty hard to say are not concrete. These pieces of evidence are analyzed by many other people such as audio/visual experts to prove that they have not been tampered or hoaxed. They continue through trial and error to help develop paranormal science. Their method of investigating is in fact to disprove before anticipating anything. Looks and sounds awfully scientific to me. So I don't get any argument on how that is not their method of operation. There have been many an episode where they have completely disproven paranormal activity and there have been a few where they actually caught people trying to fool them with speakers in the walls, etc. But afterall it is a tv show. It is produced for entertainment.
I get it that you look at everything through a science book, but there are a great deal of people dating back long before modern science that have been claiming much of the same type of experiences. Science has not quite caught up to something that may or may not exist. Narrow mindedness certainly won't help scientific discoveries. T.V. shows aside if you don't believe it and want to walk around in a box, than thats fine but there are a great deal of things that science has yet to explain.
As in another thread we had on ghosts a few months ago I told my experience and there were multiple individuals who were right there with me who experienced precisely the same thing I did. It was not a matter of hearing a creeky noise and the mind playing tricks. Frequent occurences happened for close to an hour and over several days in fact. Just because you have not experienced anything does not mean that it is not happening. Proving paranormal activity through evidence is not as easy as taking a water sample and putting it under a microscope. Sorry for the novel, but I needed to voice that.
