Choosing in freedom or forced to choose? Introspective blindness to psychological forcing in stage-magic.

We investigated an individual ability to identify whether choices were made freely or forced by external parameters. We capitalized on magical setups where the notion of psychological forcing constitutes a well trodden path. In live stage magic, a magician guessed cards from spectators while inquiri...
