The randi site? it's bullshit, they basically decide what counts and what doesn't and bla bla bla, who cares.
Me, I don't beleive in ghosts... I mean, shit, they always wear clothes, right? what's up with that? If you're to argue taht a ghost is a remenant memory, and so, it appears as it remembers itself... Well... Entropy should work on those things as well and even if they exist they should just go and die out fast... Unless you'z gonna say that STRONG ghosts can somehow eat other ghosts and become "entities" like "gods" or spirits or whatever, then I say you watch too much anime >.< Also, shouldn't there be a SHITLOAD of ghosts by now? Like, with populations growing... more death, more violant death more bla bla bla... WHERE ALL DA GHOSTS AT?!
LOL, of course they decide what counts and what doesn't counts. Cheating doesn't count for sure. However, they are flexible, and you can propose changes to how experiment is set, if they decide, that your set can be manipulated, they normally reject. They won't give someone a mill bucks for pulling out ace from their sleeves.
Like we can't See Darkness, also We can't see Ghosts, But they are part of us living with Us living around somewhere near to us, they are creatures of God, and We can't deny its present, We have heard stories about them by our parents many times, Even i am feeling scared writing this. But Speaking Honestly Never saw Ghosts and I hope i never see them.
Darkness is our word for absence of light. It's not something material, but you can see absensce of light effect, that we call darkness. You can't see something, if it doesn't exist. That's why you can't see ghosts.
Ghosts are fairy tales, to keep calm raging kids. As you can see on yourself, it worked. But point is, that you are fking grown person, not 3 yr old kid, and effects are still there. I would personally beat the crap anyone, who would try to scare my kids with ghost stories, but meh, that's me.
Humans, from their beginning, are using fear, to manipulate other persons mind. God, together with ghosts, is a fairy tale. Only for one reason. So you can be manipulated, placed in a behavioring shell, and be a sheep, following blindly someones orders, so someone, who have interest, can do with you whatever he wants. More strict that is, less questions you will ask, and better slave you will be. And it's all driven, by having power over another human being.
Basically, you are being threatened by some fantasy being, with heaven and hell, etc, just to get you in a net of fear. That 'entity (ghost, god, devil, you name it)' will do that and this to you if you don't do that or this. It's indirect threat, a concept of fear, that you accept, willingly, but not knowing, and not questioning reasons behind that. More or less, in today's societies, it is forced knowledge, it's not a matter of choice. When you do that to a kid, it's obvious it doesn't know anything, and can't question anything, and if you are doing it constantly, and teaching it, it will strongly believe in that, and less likely question that, when it grows into mature person. That is how religions work, being built on fear and threats. Nothing else to discuss here, really. It's pure psychology.
There is only one answer. Knowledge. Education. More you know about the world around you, less you will believe in stories from your childhood, and you will figure out what it is all about. ( Let me give you a hint, it's POWER ) This doesn't include hollywood movies, and tv shows about ghosts and crap.
