Magicians have astonished audiences for centuries by subtly, yet
powerfully, influencing their decisions. But there has been little
systematic study of the psychological factors that make magic tricks
work.
Now, a team of researchers from McGill University and UBC has
combined the art of conjuring and the science of psychology to
demonstrate how certain contextual factors can sway the decisions people
make, even though they may feel that they are choosing freely – a
finding with potential implications even for daily decision-making.
“We began with a principle of magic that we didn’t fully understand:
how magicians influence audiences to choose a particular card without
their awareness,” explains Jay Olson, lead author of a new study
published in Consciousness and Cognition. “We found that people tend to
choose options that are more salient or attention-grabbing, but they
don’t know why they chose them,” says Olson, a graduate student in
psychiatry in McGill University’s Raz Lab, which investigates
psychological phenomena such as attention and consciousness.
