A series of new experiments shows that analytic thinking can override intuitive assumptions, including those that underlie religious belief
By Marina Krakovsky | April 26, 2012
People who are intuitive thinkers are more likely to be religious, but getting them to think analytically even in subtle ways decreases the strength of their belief, according to a new study [ http://www.sciencemag.org/content/336/6080/493 ( http://www.sciencemag.org/lookup/doi/10.1126/science.1215647 )] in Science.
The research, conducted by University of British Columbia psychologists Will Gervais and Ara Norenzayan, does not take sides in the debate between religion and atheism, but aims instead to illuminate one of the origins of belief and disbelief. "To understand religion in humans," Gervais says, "you need to accommodate for the fact that there are many millions of believers and nonbelievers."
One of their studies correlated measures of religious belief with people's scores on a popular test of analytic thinking. The test poses three deceptively simple math problems. One asks: "If it takes five machines five minutes to make five widgets, how long would it take 100 machines to make 100 widgets?" The first answer that comes to mind—100 minutes—turns out to be wrong. People who take the time to reason out the correct answer (five minutes) are, by definition, more analytical—and these analytical types tend to score lower on the researchers' tests of religious belief.
But the researchers went beyond this interesting link, running four experiments showing that analytic thinking actually causes disbelief. In one experiment, they randomly assigned participants to either the analytic or control condition. They then showed them photos of either Rodin's The Thinker or, in the control condition, of the ancient Greek sculpture Discobolus, which depicts an athlete poised to throw a discus. (The Thinker was used because it is such an iconic image of deep reflection that, in a separate test with different participants, seeing the statue improved how well subjects reasoned through logical syllogisms.) After seeing the images, participants took a test measuring their belief in God on a scale of 0 to 100. Their scores on the test varied widely, with a standard deviation of about 35 in the control group. But it is the difference in the averages that tells the real story: In the control group, the average score for belief in God was 61.55, or somewhat above the scale's midpoint. On the other hand, for the group who had just seen The Thinker, the resulting average was only 41.42. Such a gap is large enough to indicate a mild believer is responding as a mild nonbeliever—all from being visually reminded of the human capacity to think.
Another experiment used a different method to show a similar effect. It exploited the tendency, previously identified by psychologists, of people to override their intuition when faced with the demands of reading a text in a hard-to-read typeface. Gervais and Norenzayan did this by giving two groups a test of participants' belief in supernatural agents like God and angels, varying only the font in which the test was printed. People who took the belief test in the unclear font (a typewriterlike font set in italics) expressed less belief than those who took it in a more common, easy-to-read typeface. "It's such a subtle manipulation," Norenzayan says. "Yet something that seemingly trivial can lead to a change that people consider important in their religious belief system." On a belief scale of 3 to 21, participants in the analytic condition scored an average of almost two points lower than those in the control group.
Analytic thinking undermines belief because, as cognitive psychologists have shown, it can override intuition. And we know from past research that religious beliefs—such as the idea that objects and events don't simply exist but have a purpose—are rooted in intuition. "Analytic processing inhibits these intuitions, which in turn discourages religious belief," Norenzayan explains.
Harvard University psychologist Joshua Greene, who last year published a paper on the same subject with colleagues Amitai Shenhav and David Rand, praises this work for its rigorous methodology. "Any one of their experiments can be reinterpreted, but when you've got [multiple] different kinds of evidence pointing in the same direction, it's very impressive."
The study also gets high marks from University of California, Irvine, evolutionary biologist Francisco Ayala, the only former president of the American Association for the Advancement of Science to have once been ordained as a Catholic priest, and who continues to assert that science and religion are compatible. Ayala calls the studies ingenious, and is surprised only that the effects are not even stronger. "You would expect that the people who challenge the general assumptions of their culture—in this case, their culture's religious beliefs—are obviously the people who are more analytical," he says.
The researchers, for their part, point out that both reason and intuition have their place. "Our intuitions can be phenomenally useful," Gervais says, "and analytic thinking isn't some oracle of the truth."
Greene concurs, while also raising a provocative question implicit in the findings: "Obviously, there are millions of very smart and generally rational people who believe in God," he says. "Obviously, this study doesn't prove the nonexistence of God. But it poses a challenge to believers: If God exists, and if believing in God is perfectly rational, then why does increasing rational thinking tend to decrease belief in God?"

To Keep the Faith, Don't Get Analytical

Many people with religious convictions feel that their faith is rock solid. But a new study finds that prompting people to engage in analytical thinking can cause their religious beliefs to waver, if only a little. Researchers say the findings have potentially significant implications for understanding the cognitive underpinnings of religion.
Psychologists often carve thinking into two broad categories: intuitive thinking, which is fast and effortless (instantly knowing whether someone is angry or sad from the look on her face, for example); and analytic thinking, which is slower and more deliberate (and used for solving math problems and other tricky tasks). Both kinds of thinking have their strengths and weaknesses, and they often seem to interfere with one another. "Recently there's been an emerging consensus among [researchers] … that a lot of religious beliefs are grounded in intuitive processes," says Will Gervais, a graduate student at the University of British Columbia, Vancouver, in Canada and a co-author of the new study, published today in Science.
One example comes from a study by neuroscientist and philosopher Joshua Greene and colleagues at Harvard University, published last September in the Journal of Experimental Psychology. They asked hundreds of volunteers recruited online to answer three questions with appealingly intuitive answers that turn out to be wrong. For example, "A bat and ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?" Although $0.10 comes easily to mind (it's the intuitive answer), it takes some analytical thought to come up with the correct answer of $0.05. People who chose more intuitive answers on these questions were more likely to report stronger religious beliefs [ http://www.wjh.harvard.edu/~jgreene/GreeneWJH/Shenhav-Rand-Greene-JEPG11.pdf ], even when the researchers controlled for IQ, education, political leanings, and other factors.
In the same study, another group of volunteers wrote a paragraph about a time in their lives when either following their intuition or careful reasoning led to a good outcome. Those who wrote about intuition reported stronger religious beliefs on a questionnaire taken immediately afterward. If intuitive thinking encourages religious belief, as Greene's study suggested, analytical thinking might encourage disbelief—or so Gervais and his adviser, social psychologist Ara Norenzayan, hypothesized.
To test this idea, the duo devised several ways to subconsciously put people in what they considered a more analytical mindset. In one experiment with 57 undergraduate students, some volunteers viewed artwork depicting a reflective thinking pose (such as Rodin's The Thinker) while others viewed art depicting less intellectual pursuits (such as throwing a discus) before answering questionnaires about their faith. In another experiment with 93 undergraduates and a larger sample of 148 American adults recruited online, some subjects solved word puzzles that incorporated words such as "analyze," "reason," and "ponder," while others completed similar puzzles with only words unrelated to thinking, such as "high" and "plane." In all of these experiments, people who got the thinking-related cues reported weaker religious beliefs [ http://www.sciencemag.org/content/336/6080/493 ( http://www.sciencemag.org/lookup/doi/10.1126/science.1215647 )] on the questionnaires taken afterward than did the control group.
In a final experiment, Gervais and Norenzayan asked 182 volunteers to answer a religious questionnaire as usual, while others answered the same questionnaire printed in a hard-to-read font, which previous studies have found promotes analytic thinking. And indeed, those who had to work harder to comprehend the questionnaire rated their religious beliefs lower.
Because people were randomly assigned to the analytical-thinking and control groups, and because the results were consistent across all their experiments, Gervais says it's very unlikely the findings could result from one group being more religious to begin with. Moreover, in two of these experiments, the researchers administered religious belief questionnaires to the participants a few weeks beforehand and found no difference between the groups.
The effects of the analytical-thinking manipulations were modest. "We're not turning people into atheists," says Gervais. Rather, when the questionnaire responses of all subjects in an experiment are taken together, they indicate a small shift away from religious belief.
"It's very difficult to distinguish between what a person believes and what they say they believe," says Daniel Kahneman, a psychologist and Nobel laureate at Princeton University who has done pioneering work on the contributions of intuitive and analytical thinking to human decision making. "All they have shown, and all that can be shown, is that when you're thinking more critically you reject statements that otherwise you would endorse," Kahneman says. "It tells you that there are some religious beliefs people hold that if they were thinking more critically, they themselves would not endorse."
To Gervais and Norenzayan, the findings suggest that intuitive thinking, likely along with other cognitive and cultural factors, is a key ingredient in religious belief. Greene agrees: "Through some combination of culture and biology, our minds are intuitively receptive to religion." He says, "If you're going to be unreligious, it's likely going to be due to reflecting on it and finding some things that are hard to believe."
"In some ways this confirms what many people, both religious and nonreligious, have said about religious belief for a long time, that it's more of a feeling than a thought," says Nicholas Epley, a psychologist at the University of Chicago. But he predicts the findings won't change anyone's mind about whether God exists or whether religious belief is rational. "If you think that reasoning analytically is the way to go about understanding the world accurately, you might see this as evidence that being religious doesn't make much sense," he says. "If you're a religious person, I think you take this evidence as showing that God has given you a system for belief that just reveals itself to you as common sense."
