Nautilus Magazine: Atheism, the Computer Model

Or so says the Pew Research Religious Landscape Study, which in 2015 found that almost a quarter of Americans profess no religious affiliation. Within that group, a third do not believe in God or a higher power of any sort (“nothing in particular,” as the study termed it). Both numbers are up from a similar study in 2007, when 16 percent of the country professed no religious affiliation, and 22 percent of these did not believe in God. Driving the growth are Millennials, those born between 1980 and 2000. As they come of age, 70 percent of them say they do not believe in a higher power.

Pew expects the percent of religious Americans will continue to fall. It suggests older generations will die off and take their belief with them. Outside the U.S., a WIN/Gallup International poll found that more than half of Vietnamese, Koreans, and French people say they are atheists or not affiliated with a religion. For the Japanese and Germans, it’s more than 60 percent, and for the Dutch and British, two-thirds. Certainly, belief in nothing has market momentum. [...]

The idea of trying to model the impact of something as complex as religion in civilization was interesting to Saikou Y. Diallo, research associate professor at VMASC, in part because of the challenge of coming up with ways to model things that are qualitative, like emotions or beliefs. “Obviously, feeling emotion and such cannot be simulated, so we’re not going to attempt to do feelings and emotions,” Diallo says. “We’re going to model theories about why people feel the way they feel, look for explanations of why those feelings occur, not those feelings themselves.” [...]

Religion doesn’t create the shift from Abel to Cain, from nomadic shepherd to town-centered farmer. But it smooths out the transition, Wildman says. It makes early towns more likely to succeed. In part, that’s because religion demands unorthodox behaviors, rituals, appearing at worship services. These show who is willing to participate and who is not, which might help eliminate what economists call the free-rider problem, people who take the benefits of society without contributing to it. Those who won’t perform the rituals can be cast out, or shunned. Meanwhile, shared beliefs soften what Wildman calls “the hatred of being watched by strangers.” Religion mattered in how communities formed, Wildman says. We often think of religion as divisive, forgetting it plays an important role in bringing different people together.
