Do You Believe in Magic?

A graduate school application can go sour in as many ways as a blind date. The personal essay might seem too eager, the references too casual. The admissions officer on duty might be nursing a grudge. Or a hangover.

Rachel Riskind of Austin, Tex., nonetheless has a good feeling about her chances for admittance to the University of Michigans exclusive graduate program in psychology, and its not just a matter of her qualifications.

On a recent afternoon, as she was working on the admissions application, she went out for lunch with co-workers. Walking from the car to the restaurant in a misting rain, she saw a woman stroll by with a Michigan umbrella.

I felt it was a sign; you almost never see Michigan stuff here, said Ms. Riskind, 22. And I guess I think that has given me a kind of confidence. Even if its a false confidence, I know that that in itself can help people do well.

Psychologists and anthropologists have typically turned to faith healers, tribal cultures or New Age spiritualists to study the underpinnings of belief in superstition or magical powers. Yet they could just as well have examined their own neighbors, lab assistants or even some fellow scientists. New research demonstrates that habits of so-called magical thinking the belief, for instance, that wishing harm on a loathed colleague or relative might make him sick are far more common than people acknowledge.

These habits have little to do with religious faith, which is much more complex because it involves large questions of morality, community and history. But magical thinking underlies a vast, often unseen universe of small rituals that accompany people through every waking hour of a day.

The appetite for such beliefs appears to be rooted in the circuitry of the brain, and for good reason. The sense of having special powers buoys people in threatening situations, and helps soothe everyday fears and ward off mental distress. In excess, it can lead to compulsive or delusional behavior. This emerging portrait of magical thinking helps explain why people who fashion themselves skeptics cling to odd rituals that seem to make no sense, and how apparently harmless superstition may become disabling.

The brain seems to have networks that are specialized to produce an explicit, magical explanation in some circumstances, said Pascal Boyer, a professor of psychology and anthropology at Washington University in St. Louis. In an e-mail message, he said such thinking was only one domain where a relevant interpretation that connects all the dots, so to speak, is preferred to a rational one.

Children exhibit a form of magical thinking by about 18 months, when they begin to create imaginary worlds while playing. By age 3, most know the difference between fantasy and reality, though they usually still believe (with adult encouragement) in Santa Claus and the Tooth Fairy. By age 8, and sometimes earlier, they have mostly pruned away these beliefs, and the line between magic and reality is about as clear to them as it is for adults.

It is no coincidence, some social scientists believe, that youngsters begin learning about faith around the time they begin to give up on wishing. The point at which the culture withdraws support for belief in Santa and the Tooth Fairy is about the same time it introduces children to prayer, said Jacqueline Woolley, a professor of psychology at the University of Texas. The mechanism is already there, kids have already spent time believing that wishing can make things come true, and theyre just losing faith in the efficacy of that.

If the tendency to think magically were no more than self-defeating superstition, then over the pitiless history of human evolution it should have all but disappeared in intellectually mature adults.

Yet in a series of experiments published last summer, psychologists at Princeton and Harvard showed how easy it was to elicit magical thinking in well-educated young adults. In one instance, the researchers had participants watch a blindfolded person play an arcade basketball game, and visualize success for the player. The game, unknown to the subjects, was rigged: the shooter could see through the blindfold, had practiced extensively and made most of the shots.

On questionnaires, the spectators said later that they had probably had some role in the shooters success. A comparison group of participants, who had been instructed to visualize the player lifting dumbbells, was far less likely to claim such credit.

In another experiment, the researchers demonstrated that young men and women instructed on how to use a voodoo doll suspected that they might have put a curse on a study partner who feigned a headache. And they found, similarly, that devoted fans who watched the 2005 Super Bowl felt somewhat responsible for the outcome, whether their team won or lost. Millions in Chicago and Indianapolis are currently trying to channel the winning magic.

The question is why do people create this illusion of magical power? said the lead author, Emily Pronin, an assistant professor of psychology and public affairs at Princeton. I think in part its because we are constantly exposed to our own thoughts, they are most salient to us and thus we are likely to overestimate their connection to outside events.

The brain, moreover, has evolved to make snap judgments about causation, and will leap to conclusions well before logic can be applied. In an experiment presented last fall at the Society for Neuroscience meeting, Ben Parris of the University of Exeter in England presented magnetic resonance imaging scans taken from the brains of people watching magic tricks. In one, the magician performed a simple sleight of hand: he placed a coin in his palm, closed his fingers over it, then opened his hand to reveal that the coin was gone.

Dr. Parris and his colleagues found spikes of activity in regions of the left hemisphere of the brain that usually become engaged when people form hypotheses in uncertain situations.

These activations occur so quickly, other researchers say, that they often link two events based on nothing more than coincidence: I was just thinking about looking up my high school girlfriend when out of the blue she called me, or, The day after I began praying for a quick recovery, she emerged from the coma.

For people who are generally uncertain of their own abilities, or slow to act because of feelings of inadequacy, this kind of thinking can be an antidote, a needed activator, said Daniel M. Wegner, a professor of psychology at Harvard. (Dr. Wegner was a co-author of the voodoo study, with Kimberly McCarthy of Harvard and Sylvia Rodriguez of Princeton.)

I deal with students like this all the time and I say, Lets get you overconfident, Dr. Wegner said. This feeling that your thoughts can somehow control things can be a needed feeling the polar opposite of the helplessness, he added, that so often accompanies depression.

Magical thinking is most evident precisely when people feel most helpless. Giora Keinan, a professor at Tel Aviv University, sent questionnaires to 174 Israelis after the Iraqi Scud missile attacks of the 1991 gulf war. Those who reported the highest level of stress were also the most likely to endorse magical beliefs, like I have the feeling that the chances of being hit during a missile attack are greater if a person whose house was attacked is present in the sealed room, or To be on the safe side, it is best to step into the sealed room right foot first.

It is of interest to note, Dr. Keinan concluded, that persons who hold magical beliefs or engage in magical rituals are often aware that their thoughts, actions or both are unreasonable and irrational. Despite this awareness, they are unable to rid themselves of such behavior.

On athletic fields, at the craps table or out sailing in the open ocean, magical thinking is a way of life. Elaborate, entirely nonsensical rituals are performed with solemn deliberation, complete with theories of magical causation.

I am hoping I do not change my clothes for the rest of the season, that I really start to stink, said Tom Livatino, head basketball coach at Lincoln Park High School in Chicago, who wears the same outfit as long as his team is winning. (And it usually does.)

The idea, Mr. Livatino said, is to do as much as possible to recreate the environment that surrounds his teams good play. He doesnt change his socks; he doesnt empty his pockets; and he works the sideline with the sense he has done everything possible to win. The full commitment, he explained. Ill do anything to give us an edge.

Only in extreme doses can magical thinking increase the likelihood of mental distress, studies suggest. People with obsessive-compulsive disorder are often nearly paralyzed by the convictions that they must perform elaborate rituals, like hand washing or special prayers, to ward off contamination or disaster. The superstitions, perhaps harmless at the outset, can grow into disabling defense mechanisms.

Those whose magical thoughts can blossom into full-blown delusion and psychosis appear to be a fundamentally different group in their own right, said Mark Lenzenweger, a professor of clinical science, neuroscience and cognitive psychology at Binghamton, part of the State University of New York. These are people for whom magical thinking is a central part of how they view the world, not a vague sense of having special powers, he said. Whereas with most people, if you were to confront them about their magical beliefs, they would back down.

Reality is the most potent check on runaway magical thoughts, and in the vast majority of people it prevents the beliefs from becoming anything more than comforting and disposable private rituals. When something important is at stake, a test or a performance or a relationship, people dont simply perform their private rituals: they prepare. And if their rituals start getting in the way, they adapt quickly.

Mr. Livatino lives and breathes basketball, but he also recently was engaged to be married.

I can tell you she doesnt like the clothes superstition, he said. She has made that pretty clear.
