Naked Science : Telepathy (National Geographic)

The supposed ability of some individuals to mentally transmit and receive thoughts is examined in this hour. Unsubstantiated claims are not proof, so several experiments are conducted to put the phenomenon to the test. This includes exploring the telepathic connection that some twins claim to experience through a series of tests on one twin and recording the other twin's reaction, and a Ganzfeld test where a person in one room attempts to transmit mental pictures to another person in a different room.
