We often fall victim of an illusory sense of control and agency over our thoughts and actions. Magicians are masters at exploiting these illusions, and forcing techniques provide a powerful way to study apparent action causation-the illusion that our action caused the outcome we get. In this article, we used the Criss-Cross force to study whether people can tell the difference between an action which had an impact on the outcome they get and one which has no impact. In the Criss-Cross force, participants are asked to cut to a card, and while they are genuinely free to cut the cards at any position, the cut does not affect the card they are given (i.e., they always get the top card). We investigate the psychological processes that underpin the success of this force. Experiment 1 (N = 60) showed that participants cannot tell the difference between a forced and a controlled outcome. Experiment 2 (N = 90) showed that contrary to common magicians' knowledge, misdirection does not play a role in the success of the force. Finally, Experiment 3 (N = 60) suggests that rather than misdirection, an attribute substitution error explains why people fail to understand that their action does not have an impact on the outcome they get. Debriefing also shows the importance of participants' expectations in the perception of the trick, as well as the role of prediction of the outcome in participants' sense of agency over the events.
