Résumé :
Magicians use deception to create effects that allow us to experience the impossible. More recently, magicians have started to contextualize these tricks in psychological demonstrations. We investigated whether witnessing a magic demonstration alters people’s beliefs in these pseudo-psychological principles. In the classroom, a magician claimed to use psychological skills to read a volunteer’s thoughts. After this demonstration, participants reported
higher beliefs that an individual can 1) read a person’s mind by evaluating micro expressions, psychological profiles and muscle activities, and 2) effectively prime a person’s behaviour through subtle suggestions. Whether he was presented as a magician or psychologist did not influence people’s beliefs about how the demonstration was achieved, nor did it influence their beliefs in pseudo-psychological principles. Our results demonstrate that
pseudo-psychological demonstrations can have a significant impact on perpetuating false beliefs in scientific principles and raise important questions about the wider impact of scientific misinformation.
