Magical thinking

Get this:

Dopamine, a neurotransmitter that the brain uses to tag experiences as meaningful, floods the brains of schizophrenics, who see significance in everything, but merely trickles in many depressives, who struggle to find value in everyday life. In one experiment, paranormal believers (who are high in dopamine) were more prone than nonbelievers to spot nonexistent faces when looking at jumbled images and also were less likely to miss the faces when they really were there. Everyone spotted more faces when given dopamine-boosting drugs. Brugger argues that the ability to see patterns and make loose associations enhances creativity and also serves a practical function: "If you're on the grassland, it's always better to assume that a tiger is there."
