Deception and misinformation


Magic is an artform that involves deception and revelation to create experiences that violate our understanding of the world.  In most instances this form of deception is simply used to entertain audiences, but similar techniques can and are deployed to intentionally misinform and mislead the public.  Spiritualist medium have often used conjuring principles to convince the public of their supernatural powers.  


In collaboration with Prof. Christine Mohr, at Lausanne University, we have run an extensive research project that examines the impact that such misinformation can have on people’s beliefs.  In some of these experiments, we collaborated with magicians (Lee Hathaway) to create live demonstrations in which a medium was able to contact the spiritual underworld to divine information from individuals.  To much of our surprise, a relatively large proportion of our participants believed that such phenomena were genuinely possible.  What was even more surprising, was that telling people in advance that these demonstrations were accomplished through trickery had virtually no impact on our participants beliefs.  Even when they were explicitly told that the demonstrations were fake, several of our participants believed that our fake medium’s supernatural powers were genuine.  More worryingly, our results showed that such demonstrations, even when explicitly labelled as fake can enhance people’s beliefs in spiritualist phenomena.  We have also conducted studies in which we used magic trickery to demonstrate pseudo-scientific psychological skills, such as body language reading, and here the effects were even stronger.  


It's only once these demonstrations are entirely debunked, by explicitly exposing how the tricks are done, that the spread of misinformation can be mitigated.  In fact, debunking a psychic demonstration reduced people’s beliefs in the paranormal, which suggests that such demonstration may offer a valuable tool to promote critical thinking.  More generally we believe that magic provides a great tool to investigate the impact that misinformation has on our beliefs.
