Dr. Novella looks at an interesting point that has long bugged the hell out of me.
As far as I know the mortality rate due to ghosts is zero. There are no credibly documented cases of anyone being injured or killed by a ghost. Besides - they are supposed to be immaterial, so how could they harm you? They might make you a bit chilly, or give you a severe case of the willies, but that’s it. I suppose they could frighten a weak-hearted person to death, in which case all we have to fear is fear itself.
And this is a common thing seen in the TV "reality" shows about ghosties. I understand the average person being jumpy with they saw something odd, it is a surprise, unexpected. But these shows...they jump, scream, and run. Granted they don't do it as much on Ghost Hunters, but it happens a little (Especially it was notable when they were in Europe with that Irish idiot, who was always running around panicked.). But on most shows they scream and run all over the place. They are trying, allegedly to gather evidence, and delve into the mystery, yet when their is a "physical manifestation" they bolt (I am looking you Ghost Adventures, bug brave guys yipping over bumps in the night, snakes, and prairie dog holes.). The moment they may be on the cusp of success they just quit it.
It comes off as kids playing pretend and getting themselves overexcited. Kids telling stories by flashlight, or by a fire. They try to act like adults, but... Maybe that is why I can almost find Most Haunted amusing. It is so ridiculous, it is hard to believe they want you to take it serious. But it is a silly. A video error is a ghost, a speck of dust is a ghost, a crack on an audio recording...a ghost!!!
As Novella notes, their is one hospital that has people claiming it is haunted and an exorcist is being called in. A place of medicine and science doing this. So psychologist around they could talk with? But we see this again and again, like in New Orleans after Katrina, the military brought in priests, for the buildings.
