Clairvoyance is an alleged extrasensory ability to see things beyond the range of the power of vision. Clairvoyance is usually associated with precognition or retrocognition .
People can predict the future.
We do it all the time, but we usually, if not always, do it by taking into account our experience, knowledge and surroundings. No doubt much of our anticipation of the future is unconscious and second nature, but it is based on quite natural and mundane abilities not on mysterious or supernatural powers. However, psychic predictions are not any more accurate than educated guesses. Under the heading of mass media error and hype, we include not just cases of error and complicity by silence or ignorance, as in the false claim about Jean Dixon that she predicted the assassination of President Kennedy. Some predictions by psychics do come true.
