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...
