Having delusions, such as a belief in telekinesis, can influence how people see the world - literally.
A mechanism for how the brain creates and maintains delusions is revealed in a new study.
Human beliefs are shaped by perception, but the new research suggests delusions — unfounded but tightly held beliefs — can turn the tables and actually shape perception. People who are prone to forming delusions may not correctly distinguish among different sensory inputs, and may rely on these delusions to help make sense of the world, the study finds. Typical delusions include paranoid ideas or inflated ideas about oneself.
"Beliefs form in order to minimize our surprise about the world," said neuroscientist Phil Corlett of Yale University in New Haven, Conn., who was not involved in the study. "Our expectations override what we actually see," Corlett added. [The 10 Biggest Mysteries of the Mind]
