A clairvoyant is a person who possesses the power to discern or detect objects without using the usual senses of seeing, hearing, touching, tasting, or smelling. The small number of people with this form of extra-sensory perception can be said to possess a sixth sense. Many people skeptical of clairvoyance and telepathy have been forced to admit that such phenomena cannot be explained in terms of the laws of normal physics and psychology. A simple method of detecting clairvoyance is to have a person hold a shuffled pack of cards face down. The person is then asked to guess the top card, then the next one, and so on throughout the deck. Usually the pack of cards will be in front of the clairvoyant, but sometimes it is not even in the same room. Experiments at various psychic research centers have produced some remarkable successes. One famous clairvoyant is recorded as having seen a crashed car on a road which, to all other observers, was absolutely deserted. Only a day later a car did crash on the exact spot previously seen.
