A growing number of people, millions worldwide, say they believe that life definitively ends at death – that there is no God, no afterlife and no divine plan. And it’s an outlook that could be gaining momentum – despite its lack of cheer. In some countries, openly acknowledged atheism has never been more popular.
“There’s absolutely more atheists around today than ever before, both in sheer numbers and as a percentage of humanity,” says Phil Zuckerman, a professor of sociology and secular studies at Pitzer College in Claremont, California, and author of
Living the Secular Life. According to a
Gallup International survey of more than 50,000 people in 57 countries, the number of individuals claiming to be religious fell from 77% to 68% between 2005 and 2011, while those who self-identified as atheist rose by 3% – bringing the world’s estimated proportion of adamant non-believers to 13%.
While atheists certainly are not the majority, could it be that these figures are a harbinger of things to come? Assuming global trends continue might religion someday disappear entirely?
It’s impossible to predict the future, but examining what we know about religion – including why it evolved in the first place, and why some people chose to believe in it and others abandon it – can hint at how our relationship with the divine might play out in decades or centuries to come.
Scholars are still trying to tease out the complex factors that drive an individual or a nation toward atheism, but there are a few commonalities. Part of religion’s appeal is that it offers security in an uncertain world. So not surprisingly, nations that report the highest rates of atheism tend to be those that provide their citizens with relatively high economic, political and existential stability. “Security in society seems to diminish religious belief,” Zuckerman says. Capitalism, access to technology and education also seems to correlate with a corrosion of religiosity in some populations, he adds.
Crisis of faith
Japan, the UK, Canada, South Korea, the Netherlands, the Czech Republic, Estonia, Germany, France and Uruguay (where the majority of citizens have European roots) are all places where religion was important just a century or so ago, but that now report some of the lowest belief rates in the world. These countries feature strong educational and social security systems, low inequality and are all relatively wealthy. “Basically, people are less scared about what might befall them,” says Quentin Atkinson, a psychologist at the University of Auckland, New Zealand.
Yet decline in belief seems to be occurring across the board, including in places that are still strongly religious, such as Brazil, Jamaica and Ireland. “Very few societies are more religious today than they were 40 or 50 years ago,” Zuckerman says. “The only exception might be Iran, but that’s tricky because secular people might be hiding their beliefs.”
The US, too, is an outlier in that it is one of the wealthiest countries in the world, but also has high rates of religiosity. (Still,
a recent Pew surveyrevealed that, between 2007 and 2012, the proportion of Americans who said they are atheist rose from 1.6% to 2.4%.)
Decline, however, does not mean disappearance, says Ara Norenzayan, a social psychologist at the University of British Columbia in Vancouver, Canada, and author of
Big Gods. Existential security is more fallible than it seems. In a moment, everything can change: a drunk driver can kill a loved one; a tornado can destroy a town; a doctor can issue a terminal diagnosis. As climate change wreaks havoc on the world in coming years and natural resources potentially grow scarce, then suffering and hardship could fuel religiosity. “People want to escape suffering, but if they can’t get out of it, they want to find meaning,” Norenzayan says. “For some reason, religion seems to give meaning to suffering – much more so than any secular ideal or belief that we know of.”
This phenomenon constantly plays out in hospital rooms and disaster zones around the world. In 2011, for example, a massive earthquake struck Christchurch, New Zealand – a highly secular society. There was a
sudden spike of religiosity in the people who experienced that event, but the rest of the country remained as secular as ever. While exceptions to this rule do exist – religion in Japan plummeted following World War II, for instance – for the most part, Zuckerman says, we adhere by the Christchurch model. “If experiencing something terrible caused all people to become atheists, then we’d all be atheists,” he says.
The mind of god
But even if the world’s troubles were miraculously solved and we all led peaceful lives in equity, religion would probably still be around. This is because a god-shaped hole seems to exist in our species’ neuropsychology, thanks to a quirk of our evolution.
Understanding this requires a delve into “dual process theory”. This psychological staple states that we have two very basic forms of thought: System 1 and System 2. System 2 evolved relatively recently. It’s the voice in our head – the narrator who never seems to shut up – that enables us to plan and think logically.
System 1, on the other hand, is intuitive, instinctual and automatic. These capabilities regularly develop in humans, regardless of where they are born. They are survival mechanisms. System 1 bestows us with an innate revulsion of rotting meat, allows us to speak our native language without thinking about it and gives babies the ability to recognise parents and distinguish between living and nonliving objects. It makes us prone to looking for patterns to better understand our world, and to seek meaning for seemingly random events like natural disasters or the death of loved ones.
In addition to helping us navigate the dangers of the world and find a mate, some scholars think that System 1 also enabled religions to evolve and perpetuate. System 1, for example, makes us instinctually primed to see life forces – a phenomenon called hypersensitive agency detection – everywhere we go, regardless of whether they’re there or not. Millennia ago, that tendency probably helped us avoid concealed danger, such as lions crouched in the grass or venomous snakes concealed in the bush. But it also made us vulnerable to inferring the existence of invisible agents – whether they took the form of a benevolent god watching over us, an unappeased ancestor punishing us with a drought or a monster lurking in the shadows.
Similarly, System 1 encourages us to see things dualistically, meaning we have trouble thinking of the mind and body as a single unit. This tendency emerges quite early: young children, regardless of their cultural background, are inclined to believe that
they have an immortal soul – that their essence or personhood existed somewhere prior to their birth, and will always continue to exist. This disposition easily assimilates into many existing religions, or – with a bit of creativity – lends itself to devising original constructs.
“A Scandinavian psychologist colleague of mine who is an atheist told me that his three-year-old daughter recently walked up to him and said, ‘God is everywhere all of the time.’ He and his wife couldn’t figure out where she’d gotten that idea from,” says Justin Barrett, director of the Thrive Center for Human Development at Fuller Theological Seminary in Pasadena, California, and author of
Born Believers. “For his daughter, god was an elderly woman, so you know she didn’t get it from the Lutheran church.”
For all of these reasons, many scholars believe that religion arose as “a byproduct of our cognitive disposition”, says Robert McCauley, director of the Center for Mind, Brain and Culture at Emory University in Atlanta, Georgia, and author of
Why Religion Is Natural and Science Is Not. “Religions are cultural arrangements that evolved to engage and exploit these natural capacities in humans.”
