I'm pretty sure most of you already know about the show "Ghost Hunters" that started a few years ago on the Sci-Fi channel, and the half dozen similar reality shows that have popped up since. What I want to know is, do these investgations stand any chance of finding actual ghosts? So far, on nearly every episode, they figure out that what they were investigating was either totally ambiguous or easily explained by normal causes.
Every show goes basically the same way: They set up heat-sensitive cameras to catch "cold spots" and EMF detectors to catch unusual electromagnetic activity, and then break up into teams of two to wander around the location through the night. Typically they also do some basic EVP question-answer sessions.
I used to be a big fan of these shows, but the near-constant failure to find anything convincing got really old. Are the people on these shows doing something wrong? Do earthbounds and negative-energy spirits just not show up reliably on video cameras?
