[Wallace T.]

Shortly after the assassination of President Kennedy, an astrologer and self-styled psychic named Jeane Dixon claimed that she foresaw the assassination. However, she made a number of predictions that were wrong. There was a popular writer in the 1970s that took various rock paintings and concluded they were evidence of visitors from outer space. There was the "Sleeping Prophet" of Virginia Beach, Edgar Cayce, who predicted that Atlantis would resurface in the Bahamas in the 1970s. Another self-styled psychic, the Amazing Criswell, said the world would be destroyed in 1989.

Even excluding the climate doom cult and fringe Christian prophecy writers who claimed some political figure or other, such as Gorbachev, Kissinger, or King Juan Carlos, was the Antichrist foreseen in the Book of Revelation, there have been numerous people who have made wrong predictions.
