The One Million Dollar Paranormal Challenge was a contest created by illusionist and skeptic James Randi in 1964. The challenge offered a prize of one million dollars to anyone who could demonstrate paranormal abilities under controlled conditions. Randi aimed to promote critical thinking and skepticism regarding claims of the supernatural. The challenge attracted numerous participants over the years, including psychics and mediums, but no one successfully claimed the prize. In 2015, Randi announced the challenge would be discontinued after his passing, but it remains a significant part of discussions surrounding paranormal phenomena and skepticism in popular culture.
