One of my projects is a collaboration with the psychologist Mihaly Csikszentmihalyi (pronounced shick-sent-me-hi), who is best known among general readers for his books on peak psychological experience, such as Flow and The Evolving Self. Csikszentmihalyi pioneered the Experience Sampling Method (ESM) which involves signaling people at random times during the day, prompting them to record their external and internal experience — where they are, who they are with, what they are doing, and what they are thinking and feeling on a checklist of numerical scales. The ESM is like an invisible observer, following people around as they go about their daily lives. It is as close as psychological research gets to the careful field studies that evolutionary biologists are accustomed to performing on non-human species, which is why I teamed up with Csikszentmihalyi to analyze some of his past studies from an evolutionary perspective.
These studies were performed on such a massive scale and with so much background information that we can compare the psychological experience of religious believers vs. nonbelievers on a moment-by-moment basis. We can even compare members of conservative vs. liberal protestant denominations, when they are alone vs. in the company of other people. On average, religious believers are more prosocial than non-believers, feel better about themselves, use their time more constructively, and engage in long-term planning rather than gratifying their impulsive desires. On a moment-by-moment basis, they report being more happy, active, sociable, involved and excited. Some of these differences remain even when religious and non-religious believers are matched for their degree of prosociality. More fine-grained comparisons reveal fascinating differences between liberal vs. conservative protestant denominations, with more anxiety among the liberals and conservatives feeling better in the company of others than when alone. Religions are diverse, in the same way that species in ecosystems are diverse. Rather than issuing monolithic statements about religion, evolutionists need to explain religious diversity in the same way that they explain biological diversity.
These results raise as many questions as they answer. We did not evolve to feel good but rather to survive and reproduce. Perhaps religious believers are happily unaware of the problems that nonbelievers are anxiously trying to solve. As a more subtle point, people pass back and forth between the categories of “nonbeliever” and “believer” as they lose and regain faith. Perhaps some nonbelievers are psychologically impaired because they are the recent casualties of religious belief. Only more scientific legwork can resolve these issues, but one thing is sure: Dawkins’ armchair speculation about the guilt-inducing effects of religion doesn’t even get him to first base.
