Michael Shermer in Scientific American:
Imagine a time in your life when you felt out of control—anything from getting lost to losing a job. Now look at the top illustration on this page. What do you see? Such a scenario was presented to subjects in a 2008 experiment by Jennifer Whitson of the University of Texas at Austin and her colleague Adam Galinsky of Northwestern University. Their study, entitled “Lacking Control Increases Illusory Pattern Perception,” was published in Science.
Defining “illusory pattern perception” (what I call “patternicity”) as “the identification of a coherent and meaningful interrelationship among a set of random or unrelated stimuli … (such as the tendency to perceive false correlations, see imaginary figures, form superstitious rituals, and embrace conspiracy beliefs, among others),” the researchers’ thesis was that “when individuals are unable to gain a sense of control objectively, they will try to gain it perceptually.” As Whitson explained the psychology to me, “Feelings of control are essential for our well-being—we think clearer and make better decisions when we feel we are in control. Lacking control is highly aversive, so we instinctively seek out patterns to regain control—even if those patterns are illusory.”
