RELIGION occupies a strange position in the world today. Religious belief is as powerful as ever, yet religion is under attack, challenged by science and Enlightenment thought as never before.
Critics like Richard Dawkins would have us believe that it is a delusion, and a dangerous one at that. He is one of many thinkers who are challenging the traditional view of religion as a source of morality. Instead, they argue that it provides a means for justifying immoral acts.
Their views have recently been bolstered by evidence that morality appears to be hard-wired into our brains. It seems we are born with a sense of right and wrong, and that no amount of religious indoctrination will change our most basic moral instincts.
Many biologists are not convinced by such radical views, however.
Recent years have seen a flurry of activity by researchers who want to assess the effects of religion on human behaviour. It is a fiendishly difficult area for science, but they are starting to address the issue by looking at how religion might have evolved, what purpose it has served, and whether it really can make you a moral person - or an immoral one.
As a result of this work a new view is emerging that challenges simplistic ideas about the link between religion and morality.
Instead of religion being a source of morality or immorality, some researchers now believe that morality and religion are both deep-rooted aspects of human nature.
We do not need religion to live moral lives, but without it morality might never have evolved. This kind of thinking could explain the complex and apparently contradictory relationship between religious beliefs and moral behaviour that is being demonstrated. It could also make some sense of religion's remarkable staying power, as well as highlighting the futility of attempts to persuade believers to abandon their faith by rational argument.
There is no shortage of research supporting the case for religion as a force for good. In the late 1970s and 1980s sociologists Rodney Stark and William Sims Bainbridge, then at the University of Washington in Seattle, forcefully argued the line that religious beliefs correlated with moral behaviour. Their studies showed that church attendance and religiosity increase the collective understanding of moral norms and make people less likely to turn to crime. More recently, various surveys have suggested that moderate religious people are happier, more caring, just and compassionate, and give more money to charity. Other studies show that religion can help people quit smoking, drugs and alcohol. Religion can also affect people's sexual morality. Recent research by RAND Health, a US non-profit policy research group, has found that people with HIV who professed religious beliefs had fewer sexual partners than those who were not religious (Journal of Sex Research, vol 44, p 49).
However, religious belief is not the only moral guide, even for believers. The RAND study also found that HIV-positive Catholics were more likely to use condoms than other groups despite their church's prohibition on birth control. "Catholics increasingly are inclined to consider their individual consciences as sources of moral authority," says David Kanouse, one of the study's authors. The work certainly doesn't contradict the view that moral values come from within (see "Born to be moral"), suggesting instead that religion can provide an additional source of rationalisation to help us interpret our innate sense of right and wrong.
How does this square with claims that religion makes for bad people and bad societies?
Dawkins and others point to many examples of the use of religious beliefs to rationalise acts of hatred or war. They also cite morally reprehensible acts endorsed in religious scripture - stoning adulterers, heretics and homosexuals, beating or killing disobedient children, acceptance of slavery, even prostituting one's own daughter. They argue that religion is just a by-product of other cognitive processes and has nothing to do with our underlying morality.
Besides, many
atheists manage to be good without God
- and religious believers are not necessarily better at following their own moral codes than non-believers. Philosopher Dan Dennett from Tufts University in Boston points out that the prison population - at least in the US - has the same religious structure as the rest of society, and that divorce rates among Christians are if anything higher than among non-religious Americans.
“Many atheists manage to be good without God
”
In 2005, Greg Paul, an independent researcher from Baltimore, Maryland, published a study that attempted to quantify negative effects of religion (Journal of Religion and Society, vol 7, p 1). He compared levels of religiosity with various indicators of social dysfunction in 18 developed nations. He concluded that
countries with higher rates of belief and worship had higher rates of homicide, death among children and young adults, sexually transmitted diseases, teen pregnancy and abortion. Paul now believes that morality does not stem from religion, and that religion arises from insecurity within society.
"Mass belief in gods is primarily a fear and anxiety-based response to insufficiently secure financial circumstances, and does not have a deep neurobiological, genetic or other basis,"
he says.
His study has not been without critics, however. Some researchers have argued that his choice of nations and indicators of moral health were selective. In an attempt to provide a more rigorous test, sociologist Gary Jensen from Vanderbilt University in Nashville, Tennessee, conducted a more detailed analysis of just one of Paul's indicators, homicide, to see how it correlated with various religious beliefs. He found that homicide rates were indeed linked with passionate beliefs, though the strongest correlation occurred in societies with prominent dualist beliefs in good and evil, God and the devil. The highest rates were seen in the US - where as many as 96 per cent of the population claim to believe in God and 76 per cent in the devil - along with the Philippines, the Dominican Republic and South Africa. The correlation was much weaker in societies with a belief in God, but no strong beliefs in the devil, such as Sweden, where only 18 per cent claim to believe in both. "Gods do matter," Jensen says, "but in a far more complex manner than proposed." (Journal of Religion and Society, vol 8, p 1).
A similarly complex picture has emerged about the role of religion as a force for good. Daniel Batson, a social psychologist from the University of Kansas in Lawrence, looked at two categories: "intrinsic" religiosity - belief in God and a motivation to attend church as an end in itself - and "extrinsic" religiosity - where religion and churchgoing are seen primarily as social activities, often undertaken for personal gain. He found some correlation between intrinsic religious beliefs and compassion or reduced prejudice. By contrast, extrinsic religiosity is linked to increased prejudice - people in this group tend to be less helpful to others, and when they do assist it is only for people they see as the "right" sort.
Batson also identifies a third category he calls "quest" religiosity - a more questioning form of spirituality. His experiments reveal that while people in this category show intolerance of behaviour that violates their own values, they are nevertheless the most tolerant and helpful towards people who exhibit such behaviour.
Such studies lend some support to the idea that religion influences moral behaviour. Yet they also raise the question of whether it does this primarily within a believer's own social group, or whether it engenders a more universal compassion and altruism.
Peter Richerson, a specialist in cultural evolution, and human ecologist Brian Paciotti, both from the University of California, Davis, used economic games to examine this distinction.
The dictator game tests people's altruism and sense of fair play. One person gets $10 and is told to offer some of it to another, anonymous player - the amount offered is due to the first player. The recipient can either accept the offered amount, in which case both parties keep their share, or punish perceived unfairness by rejecting the offer so that nobody gets a payout. In the trust game, a person is given $10 and can hand any amount to another unknown person, but this time the sum they give is doubled, and the recipient then chooses how much to return. Here the best strategy is to hand over all the money - provided that the recipient reciprocates your trust. Finally, in the public goods game, people contribute to a public fund that is then doubled by the organisers and shared out equally. The game is played anonymously and tests all kinds of morality, including the amount of altruism and cheating. The group does best if everyone donates the maximum, but generally lots of people cheat.
Richerson and Paciotti conducted all three games both in a secular university and with churchgoers who had just attended a service. They found that secular and religious people did behave differently. "There are weak and subtle effects where people who [say they are] highly religious give more," Paciotti says. This might suggest that religion fosters universal cooperation. However, like Batson, the team found that only people with intrinsic or questing religiosity were more generous and trusting, and less likely to punish unfairly. Extrinsically religious people were actually less altruistic than the non-religious. These results will please no one, says Richerson, as they show that religion is neither vital for morality nor always has a negative effect. Paciotti believes the findings support the idea that humans are hard-wired to be moral and cooperative, with religion serving to define the nature and scope of that moral behaviour and influence with whom we cooperate.
Another reason that the effects of religiosity on morality have been hard to tease apart is highlighted by a new study that also uses the dictator game. Psychologists Azim Shariff and Ara Norenzayan from the University of British Columbia in Vancouver, Canada, found that by presenting people first with a word game unscrambling either religious or non-religious phrases, even atheists could be primed to be more generous to an anonymous partner by exposure to the religious words (Psychological Science, in press). People did not notice when the game had a particularly religious theme, say the researchers, suggesting that the priming effect is unconscious. Likewise, psychologist Brad Bushman from the University of Michigan, Ann Arbor, found that both Christian and non-religious people were more aggressive towards an anonymous person after reading a religious text describing how a husband took revenge for the torture and murder of his wife - but only if they had been told that the story came from the Bible or if it contained an additional verse in which God seemed to sanction the husband's violence (Psychological Science, vol 18, p 204).
You are being watched
So why do religious concepts provoke moral behaviour even in non-believers? It's because both religion and morality are evolutionary adaptations,
says Jesse Bering, who heads the Institute of Cognition and Culture at Queen's University, Belfast, UK.
Morality does not stem from religion, as is often argued, he suggests: they evolved separately, albeit in response to the same forces in our social environment. Once our ancestors acquired language and theory of mind - the ability to understand what others are thinking - news of any individual's reputation could spread far beyond their immediate group. Anyone with tendencies to behave pro-socially would then have been at an advantage, Bering says: "What we're concerned about in terms of our moral behaviour is what other people think about us." So morality became adaptive.
At the same time the capacity for religious belief would also have emerged. Our reputation-conscious ancestors would have experienced a pervasive feeling of being watched and judged, he says, which they would readily have attributed to supernatural sources since the cognitive system underlying theory of mind also seeks to attribute intentionality and meaning, even where there is none. So the same adaptations that led to morality could also have driven the evolution of religion.
Meanwhile, evolutionary biologist David Sloan Wilson of the State University of New York argues that
religious practices are also important for group cohesion and are therefore subject to group selection. As humans have become ever more social over the past 100,000 years, and especially from 10,000 years ago, when agriculture led to huge division of labour in societies, religion and morality would have co-evolved as ways to promote social cohesion. "
Religion did play a crucial role in giving us our moral nature, at least evolutionarily speaking," says psychologist Jonathan Haidt from the University of Virginia.
Nowadays, adds Bering,
whether we believe in a God or not, the brain architecture that causes us to behave as though we might get caught behaving badly is still present. As a result, atheists are no more likely to be immoral than believers.
Indeed, his own experiments show that, regardless of whether people believe in supernatural beings, both adults and children cheat less when performing a task in private if Bering has first primed them with the idea that there may be a "god" or a "ghost" watching.
Cultural and technological advances have also changed the way we live, making western liberal societies poor models for understanding the link between religion and morality, according to Haidt. He argues that we are now far more individualistic than our ancestors.
"Technology has changed our lives so we can live in new ways. We can now be moral without religion. We have developed other means of social control," he says, such as laws, police forces and CCTV cameras.
Yet religion does still have the power to galvanise individuals in any society. Brain-imaging experiments by Andrew Newberg at the University of Pennsylvania indicate that
people in religious or meditative states show a transient decrease in brain activity in regions representing our map of the body and our sense of self. Religious feelings do seem to be quite literally self-less, which may be one of religion's biggest draws. Many human activities - from music festivals to military service - tap into our powerful urge for group bonding. Haidt believes that we also have an evolved desire to elevate ourselves beyond our own selfish interests to a more helpful, group-oriented and selfless plane.
Haidt says
this sense of elevation is mediated through a physiological response in the release of a hormone called oxytocin, which makes us feel happy and good about ourselves. Elevation can come in many forms: we might get it from pursuing a noble goal, doing good, reading great prose, witnessing something skilful, experiencing awe or empathising with someone else who is feeling good.
Still, religious people have an extra source of elevation that many atheists lack - and scientists like Dawkins may do well to realise that even the most logical and articulate argument against religion will never eradicate this evolutionary sense of meaning.
Even if many no longer need religion for social cohesion or moral guidance, and think that atheism is the only rational route, we should nevertheless recognise that religion has had a pivotal role in our evolutionary history. It can still reinforce moral values and work with our innate moral sense. It can also be used to justify immoral behaviour towards those who do not embrace our beliefs. Like it or not, religion remains an important part of what we are.

Do the British people really want to lose that rooting in the Christian faith that has given them everything they cherish?
