Good question. But we do. Sean Coughlan:
As the title suggests, the principles behind magic are rooted in areas that overlap with psychology – perception, attention and how we process information… “Misdirection” is a key part of magic – getting people to not look at what’s important, but to distract them, change the subject, use a dramatic prop and push their attention elsewhere, so they do not see what is happening in front of their eyes.
Interestingly, fake news works much the same way.
Even if something is recognised as false, it still makes an impression and steals our attention, and researchers are looking at how understanding magic can help to investigate the world of conspiracy theories and fake information.
