How can people appear telepathic, and what is the history of duos demonstrating this type of mindreading as entertainment?
Two-person theatrical mindreading acts have been popular in the U.S. and Europe since the mid-1800s, with even earlier roots. In the most common form of this telepathy act, small objects shown to one partner roaming in the audience are correctly identified by the second performer, who is blindfolded and on stage, with no apparent communication between them.
