As I have said before Tyler Cowen from George Mason usually does this but I have found some myself. This one is:
“Since 1964, $1 million has awaited anyone who can show proof of the paranormal.That year, noted skeptic James Randi first offered anyone $10,000 if they could show objective proof of the paranormal or supernatural. Donations quickly raised the amount to $1 million.
The Foundation offers copies of its financial statement as proof of the existence of the money, and it has repeatedly extended its Paranormal Challenge to high-profile psychics like Sylvia Browne, so far to no avail.”
