(CNN) We can blame the Internet for plenty: the proliferation of porn, our obsession with cat videos, the alleged rise of teen trends like - brace yourself - eyeball licking.
But is it also a culprit in helping us lose our religion? A new study suggests it might be.
Allen Downey, a computer scientist at Olin College of Engineering in Massachusetts, set out to understand the national uptick in those who claim no religious affiliation. These are the “nones,” which the Pew Research Center considers the fastest-growing “religious” group in America.
Since 1985, Downey says, the number of first-year college students who say they're religiously unaffiliated has grown from 8% to 25%, according to the CIRP Freshman Survey.
And, he adds, stats from the General Social Survey, which has been tracking American opinions and social change since 1972, show unaffiliated Americans in the general population ballooned from 8% to 18% between 1990 and 2010.
These trends jibe with what the Pew Research Center’s Religion & Public Life Project reported in 2012. It said one in five American adults, and a third of those under 30, are unaffiliated.
Downey says he stepped into the ongoing debate about the rise of the "nones" not because he has a vested interest one way or the other, but because the topic fascinates him. He says it’s good fodder for study and appeals to students who are learning to crunch real data.
In his paper “Religious affiliation, education and Internet use,” which published in March on arXiv – an electronic collection of scientific papers – Downey analyzed data from GSS and discovered a correlation between increased Internet use and religious disaffiliation.
Internet use among adults was essentially at zero in 1990; 20 years later, it jumped to 80%, he said. In that same two-decade period, we saw a 25 million-person spike in those who are religiously unaffiliated.
People who use the Internet a few hours a week, GSS numbers showed Downey, were less likely to have a religious affiliation by about 2%. Those online more than seven hours a week were even more likely – an additional 3% more likely – to disaffiliate, he said.
Now, Downey is the first to point out that correlation doesn’t necessarily mean causation.
But he was able to control for other factors including education, religious upbringing, rural/urban environments and income, to find a link that allowed him to “conclude, tentatively, that Internet use causes disaffiliation,” he said.
“But a reasonable person could disagree.”
The Internet, he posited, opens up new ways of thinking to those living in homogeneous environments. It also allows those with doubts to find like-minded individuals around the world.
He believes decreases in religious upbringing have had the largest effect, accounting for 25% of reduced affiliation; college education covers about 5% and Internet use may account for another 20%.
That leaves 50% which he attributes to “generational replacement,” meaning those born more recently are less likely to be religiously affiliated – though he doesn’t attempt to explain why that is.
The Pew Research Center has offered its own theories.
One explanation Pew gives is that our nation is experiencing political backlash – "that young adults, in particular, have turned away from organized religion because they perceive it as deeply entangled with conservative politics and do not want to have any association with it."
More specifically, Pew explains, this brand of religion and politics is out of step with young adult views on same-sex rights and abortion.
Postponement of marriage and parenthood, broader social disengagement and general secularization of society may also play a part, according to Pew.
But to be religiously unaffiliated doesn’t require a lack of faith or spirituality, researchers say.
Yes, the "nones" group includes those who might call themselves atheists or agnostics. But it also accounts for many – 46 million people – who don't belong to a particular group but are, in some way, religious or spiritual, according to Pew.
This is all part of the changing face of society and faith, and where the Internet fits in is just part of a complicated puzzle.
The evolving landscape includes plenty of people who go online in search of spiritual and religious sustenance, said Cheryl Casey, who delved into the issue for her 2006 dissertation.
Casey, now a professor of media, society and ethics at Champlain College in Vermont, wrote about the “revirtualization of religious ritual in cyberspace” and the morphing relationship between technology and religion.
That Downey would find a correlation, that the Internet is increasing disaffiliation, makes perfect sense to her.
"The institutional control over the conversation is lifted, so it's not just a matter of more churches to choose from but more ways to have that conversation and more people to have that conversation with," she said Wednesday.
People move away from formal affiliation and toward what she calls "grass-roots religious exploration," where "the nature of the medium allows for those conversations to grow organically."
Innovations have long played a part in influencing religion, she said, and will continue to.
Something she wrote back in 2006 said it best.
“When a new technology, such as the printing press or the Internet, unleashes massive cultural change, the challenge to religion is immense. Cultural developments change how God, or the ultimate, is thought of and spoken about,” she wrote.
“The dynamics of this transformation, however, await continued investigation.”
