On a related note I went to see a fairly well publicised psychic, I didn't go because I had any troubles in my life (and at that time wouldn't for a good ten years or so other than day to day niggles), I went simply because my wildly superstitious friend wanted me to go and asked me to come with him - he did at that time have all the problems that make people want answers (marriage problems, business problems, family problems). I was well aware of the implication of body language so during my visit with this psychic I sat absolutely still, kept my eyes downcast and just listened - in short tried to give her as few clues as possible. During the fairly lengthy sitting she was unable to come up with one specific detail that related to my life and all her predictions for the future were wrong. She guessed I was married (the wedding ring may have been a clue) she got every fact about my marriage, my life, my family wrong. The predictions she'd made for the coming years proved to be wrong too. She'd assumed because I'd gone there that I must have had some problems, a woman of my age was much more likely to have some problems than others so she was simply playng the odds. However, my friend was amazed when she was able to predict that his marriage was in trouble, his business was in trouble etc - and to cap it all he found it startling when she told him his mother was a dark woman, the odds on her guessing an Arab man would have a dark mother are so slight I have to agree with him
Our meetings with her were taped, on closer inspection he'd just blanked everything out she'd got wrong and blown out of all proportion the few things she'd got right which added up to no more than statistical odds from guessing, a poor show really given the wild display of enthusiasm I know he'd have been giving her when she was on the right track.
If people want to believe they will, they can blank out ten incorrect things and focus on one very vague good guess. People who practise this jiggery pokery are better than most of us at reading people.
In my view this kind of crap should be made illegal, someone 'communicating' with a dead loved one might feel they were being given comfort, what they are being given is a load of lies that just draw out their misery while these manipulators prey on their vulnerability.
Astrology isn't as bad as this, it's fairly harmless, but it's every bit as fake in my view.
