Yet scientists are required to back up their claims not with private feelings but with publicly checkable evidence. Their experiments must have rigorous controls to eliminate spurious effects. And statistical analysis eliminates the suspicion (or at least measures the likelihood) that the apparent effect might have happened by chance alone. Paranormal phenomena have a habit of going away whenever they are tested under rigorous conditions. This is why the £740,000 reward of James Randi, offered to anyone who can demonstrate a paranormal effect under proper scientific controls, is safe. Why don't the television editors insist on some equivalently rigorous test? Could it be that they believe the alleged paranormal powers would evaporate and bang go the ratings? Consider this. If a paranormalist could really give an unequivocal demonstration of telepathy (precognition, psychokinesis, reincarnation, whatever it is), he would be the discoverer of a totally new principle unknown to physical science. The discoverer of the new energy field that links mind to mind in telepathy, or of the new fundamental force that moves objects around a table top, deserves a Nobel prize and would probably get one. If you are in possession of this revolutionary secret of science, why not prove it and be hailed as the new Newton? Of course, we know the answer. You can't do it. You are a fake. Yet the final indictment against the television decision-makers is more profound and more serious. Their recent splurge of paranormalism debauches true science and undermines the efforts of their own excellent science departments. The universe is a strange and wondrous place. The truth is quite odd enough to need no help from pseudo-scientific charlatans. The public appetite for wonder can be fed, through the powerful medium of television, without compromising the principles of honesty and reason.
