A basic form of ESP testing. It uses a deck of cards (such as regular playing cards or Zener cards) and repeated rounds of testing. This technique can be used to test for precognition, by having the subject guess a card before it is revealed, telepathy, by having the subject guess a card being looked at by the tester, etc.
