The origin of religion-4: Religion as an evolutionary adaptation

While the growth and perpetuation of religious beliefs is an interesting question, we also need to explain how they originated in the first place. How did such unreal information arise at all?

Some have argued in favor of the direct adaptation model, based on Darwinian natural selection principles, that says that the tendency to assign causation and agency to natural events is an evolutionary advantageous strategy. In more primitive times, assigning a conscious agency to natural events may have provided survival benefits that did not accrue to those who did not, since the benefits of a false positive outweighs the disadvantages of a false negative. i.e., having genes that predisposed one to assume that lightning was caused by the anger of some powerful supernatural agency (aka ‘god’) and taking evasive action by cowering in shelters was better in terms of survival value than assuming that lightning was harmless and wandering around in the open, even if the reasoning behind it was faulty. It was only much later that we realized that lightning was dangerous for non-religious reasons and could avoid its hazards using mechanisms that did not involve rituals to appease an angry supernatural power.

In an article in The New Scientist titled Born believers: How your brain creates God (subscription required), Michael Brooks elaborates on this:

The ability to conceive of gods, however, is not sufficient to give rise to religion. The mind has another essential attribute: an overdeveloped sense of cause and effect which primes us to see purpose and design everywhere, even where there is none. “You see bushes rustle, you assume there’s somebody or something there,” [Yale psychologist Paul] Bloom says.

This over-attribution of cause and effect probably evolved for survival. If there are predators around, it is no good spotting them 9 times out of 10. Running away when you don’t have to is a small price to pay for avoiding danger when the threat is real.

Another report in the New Scientist (no subscription required for this one) about a computer model by James Dow provides some support for direct adaptation. (The original paper by Dow can be read here.)

The model assumes, in other words, that a small number of people have a genetic predisposition to communicate unverifiable information to others. They passed on that trait to their children, but they also interacted with people who didn’t spread unreal information.

The model looks at the reproductive success of the two sorts of people – those who pass on real information, and those who pass on unreal information.

Under most scenarios, “believers in the unreal” went extinct. But when Dow included the assumption that non-believers would be attracted to religious people because of some clear, but arbitrary, signal, religion flourished.

“Somehow the communicators of unreal information are attracting others to communicate real information to them,” Dow says, speculating that perhaps the non-believers are touched by the faith of the religious.

The interesting conclusion here is that believers in the unreal require the support of nonbelievers in order to have their numbers grow. In other words, the ‘respect for religion’ trope that says that we should treat with respect, and even admire, the faith of sincere religious people, is actually part of the problem. This conclusion supports the strategy of the new/unapologetic atheists who seek diligently to undermine false beliefs such as god and the afterlife.

Brooks also writes that the reason our brains are so susceptible to superstitions is that they are hardwired to do so, which suggests deep evolutionary origins.

It turns out that human beings have a natural inclination for religious belief, especially during hard times. Our brains effortlessly conjure up an imaginary world of spirits, gods and monsters, and the more insecure we feel, the harder it is to resist the pull of this supernatural world.

What psychologists have found is that during hard times or times when people feel they are losing control of their lives, they are more prone to adopt religious beliefs and superstitions. During the great depression of 1929, for instance, the most authoritarian churches saw a rise in attendance. If this hardwired aspect of the brain is true, then adopting religious beliefs uncritically is the path of least resistance. It takes conscious effort and will to resist religious beliefs, which explains why atheism is a harder sell than religion.

The origin of religion-3: Do people have a ‘god gene’?

It seems clear that people want to believe in religious ideas or at last have a propensity to believe in supernatural phenomena. Is religion a social belief that developed only after complex societies formed or is a predisposition towards religion hardwired in our brains? Those who argue the former think that religious beliefs emerged late in evolutionary history as a cultural artifact, a ‘meme’ if you will, that appeared only after language and social structures appeared, and spread widely because of its utility.

Others argue that the ubiquity and durability of religious beliefs suggests (though does not conclusively establish) that they might have evolutionary advantages and that a propensity to believe in gods and the afterlife developed early on and became hardwired in our brains and spread throughout the species the same way (through natural selection) that other genetic features spread, thus providing us with what one might call a ‘religious gene’.

If so, then that raises two more questions. The first question concerns time. Did the hard-wired propensity to believe in supernatural agencies arise after the human species appeared or has it an even earlier genesis? Advocates of the former view suggest that religious beliefs are an evolutionary adaptation that appeared after humans and spread because they provide a survival advantage, by being a kind of glue that helped form tightly knit groups of early humans that provided greater success in hunting and foraging. This idea of properties selected for the benefits it confers on a group (known as ‘group selection’) is controversial because strictly speaking natural selection only works on the level of individual genes, not even a whole organism, except in so far as the organism is a vehicle that propagates the genes. Group selection seems to be possible only under very limited conditions. (See Evolution “for the Good of the Group”, David Sloan Wilson and E. O. Wilson, American Scientist, vol. 96, September-October 2008, p. 380-389.)

The origin of religion-2: The power of religion and other superstitions

When investigating the origin of religion and other superstitions, an important fact to bear in mind is that it is not just humans that base their behavior on imputing meaning to meaningless correlations. There is evidence that even animals do this, suggesting that this instinct comes from a fairly primitive part of the brain, and developed early in our evolutionary history before we branched off from those species that share this trait. We all have heard of Pavlov’s experiments with conditioning responses in animals. Behaviorist B. F. Skinner did an interesting experiment with pigeons. After the usual ones where pigeons were trained to peck at a button in order to obtain a food reward, he then did an experiment where the rewards were given out randomly. What he found was that after awhile the pigeons started going through what seemed like rituals, specific repeated behaviors. It seemed as if they were trying to figure out which pattern of actions had caused the rewards to appear in the past and were repeating them in order to ’cause’ the rewards to appear.

The origin of religion-1: Superstitions

I think we can all agree that, looked at objectively, religious beliefs result in a colossal consumption of time and resources that, to anyone outside that particular religion, seems like an enormous waste. As Richard Dawkins says:

As a Darwinian, the aspect of religion that catches my attention is its profligate wastefulness, its extravagant display of baroque uselessness.
…
Religious behavior in bipedal apes occupies large quantities of time. It devours huge resources. A medieval cathedral consumed hundreds of man-centuries in its building. Sacred music and devotional paintings largely monopolized medieval and Renaissance talent. Thousands, perhaps millions, of people have died, often accepting torture first, for loyalty to one religion against a scarcely distinguishable alternative. Devout people have died for their gods, killed for them, fasted for them, endured whipping, undertaken a lifetime of celibacy, and sworn themselves to asocial silence for the sake of religion.

Though the details differ across cultures, no known culture lacks some version of the time-consuming, wealth-consuming, hostility-provoking, fecundity-forfeiting rituals of religion.

So with all these disadvantages, and with science showing that most of the claims for religion are either false or lacking any evidentiary support, why do we still have religion? Why would such useless belief structures be so widespread and durable? Why are they able to command such a significant number of adherents? The ubiquity and longevity of religious practices cries out for explanation.

Since religious beliefs are supported by no empirical evidence, one has to look for other reasons to explain both their origin and continuation, and a good place to start is with superstitions, which are also irrational and yet they too are durable beliefs that can grab hold of people, spread widely quickly, and new ones appear all the time. So studying the origins of superstitions may give us clues as to the origin of religion.

Before every presidential election, for example, you find the media paying attention to some ‘predictor’ of the outcome. They will point to some state or county or precinct that has in the past always had a majority for the winning candidate and then focus on what that indicator might predict for the current contest. Sometimes the ‘predictors’ are something as unrelated as the winning team in the Super Bowl or stock market indices. Of course, rational people are aware that there can be no causal connection between the two events.

It is always possible to find, after the fact, some indicator that seems to correlate with some major event. For example, suppose I tell you that you should give me all your money to invest because I have an uncanny knack of predicting whether a given stock will go up or down the next day. You naturally will want some evidence of my predictive power before you give me your money. If I guarantee to do it correctly four times in a row, would you be willing to give me your money to invest? If you say yes, you are a sucker. The reason is that all I need is 16 people to agree to the same deal, each of whom does not know about the other 15. Then I give 8 of them a prediction that the stock will go up the next day and 8 that the stock will go down. I then forget about the eight who got the wrong prediction, and give four of the others the prediction that it will again go up, and the other four that it will go down. The next time, I deal with only the four who got both earlier predictions right and give two up and two down. This leaves me with two who got all three right predictions. I repeat the process and of those two, I will finally end up with one person who got all four predictions right and is now a believer that I have this amazing skill at picking stocks.

It is because of this tendency of people to not use their reasoning abilities or seek underlying mechanisms that causes superstitions to originate and conmen to flourish. When something unexpectedly good (or bad) happens, people tend to remember some of the circumstances surrounding that event. Then if another similar good (or bad) event occurs, and they recall that both occasions had some common feature, then that feature can become seen as an omen, as a good or bad luck talisman. Thus superstitious people end up wearing ‘lucky’ clothes or carrying some ‘lucky’ items or doing some ritual before an important event, based on whatever it was that happened to catch their notice. Athletes and sports fans can carry this to ridiculous extremes. Faith healers particularly exploit this to con people because people will note and remember their few alleged successes and ignore the vast number of failures.

People seem to be very susceptible to this kind of magical thinking. The latest superstition is the ‘psychic octopus‘ in Germany that has apparently picked the winner in every match involving Germany in the current soccer World Cup. (It predicted that Germany will lose to Spain today.) The need of people to seek out patterns and correlations, and think that they arise out of some underlying causal agency, seems to be innate. Because of it, it is extremely easy for superstitions to originate and for crooks to scam people into thinking that they have secret powers.

This tendency to ascribe causal relationships, and even a causal agency, to unrelated events is, as we will see in the next post, not simply a cultural trait developed in the last few thousand years in humans. It goes back quite far.

The great discovery of religions: Be nice to others

In the debate that is currently being waged between accommodationists (those who believe that science and religion are compatible worldviews) and new/unapologetic atheists like me who argue that they are not, the accommodationists usually argue that each area of knowledge is separate and has revealed different truths that complement each other. But what are these great truths that religion has supposedly revealed? Here they are vague but recently the Dalai Lama wrote an op-ed in the New York Times titled Many Faiths, One Truth where he takes a shot at addressing this.

Liberal democracy and religion-5: Israel’s bleak future as a democracy

The brutal behavior of the Israeli government in boarding an aid flotilla and killing some of the people on board and then justifying the action may have come as a shock to some but should not. For a long time, it has been clear that Israel is sliding further and further into becoming an authoritarian state based on religious orthodoxy that treats the Palestinians in the occupied territories with practices that strongly resemble the abhorrent apartheid policies that used to be practiced by South Africa.

Because of the rising influence of orthodox Jews, Israel has started making rules based purely on religion into laws that everyone, believers and non-believers alike, must follow. Recently Benjamin Netanyahu used the Bible to support his claim to be able to build in East Jerusalem.

Peter Beinart’s article describes how Israeli politics is moving farther and farther away from a liberal democracy.

Hebrew University Professor Ze’ev Sternhell is an expert on fascism and a winner of the prestigious Israel Prize. Commenting on Lieberman and the leaders of Shas in a recent Op-Ed in Haaretz, he wrote, “The last time politicians holding views similar to theirs were in power in post–World War II Western Europe was in Franco’s Spain.” With their blessing, “a crude and multifaceted campaign is being waged against the foundations of the democratic and liberal order.” Sternhell should know. In September 2008, he was injured when a settler set off a pipe bomb at his house.

The article goes on to say that the demographic trend of Israel’s Jewish population is going to make things even worse.

Israeli governments come and go, but the Netanyahu coalition is the product of frightening, long-term trends in Israeli society: an ultra-Orthodox population that is increasing dramatically, a settler movement that is growing more radical and more entrenched in the Israeli bureaucracy and army, and a Russian immigrant community that is particularly prone to anti-Arab racism. In 2009, a poll by the Israel Democracy Institute found that 53 percent of Jewish Israelis (and 77 percent of recent immigrants from the former USSR) support encouraging Arabs to leave the country. Attitudes are worst among Israel’s young.

While Israel still has a somewhat free press, there have been increasing efforts to suppress freedom of speech, going so far as to detain at the borders and then bar entry to the West Bank to Noam Chomsky when he had been invited to give a speech. The government even destroyed all copies of a newspaper that had an investigative report on the 2008 assault on Gaza. Uri Blau, the journalist who wrote it, even had to go into hiding, perhaps because it would have had stories like this one from a United Nations report:

Israeli ground troops ordered around 110 Palestinian civilians into a single home in Gaza City’s Zeitun neighborhood and ordered them to stay indoors on Sunday. On Monday morning, Israeli forces repeatedly shelled the building, killing at least 30 of the civilians inside. It then refused to allow ambulances to retrieve the dead and dying people for days.

What is going to happen is that as Israel comes more and more under the sway of its increasingly Orthodox religious right wing population, it will pursue even more racist policies towards the Palestinian people and become an even greater international pariah.

Instead of putting pressure on Israel to move in a more liberal democratic direction, the Israel lobby in the US actually encourages the authoritarian trend by trying to make sure that every politician in the US seeking high office swears unswerving loyalty to Israel. As a result, we have the executive and legislative branches willing to express support for almost any actions by Israel, even if it might harm the long-term strategic interests of the US. The way it manages to pull this off is by making it seem as if the interests of the US and Israel are identical. Glenn Greenwald recently highlighted New York senator Charles Shumer’s abhorrent views where he states that he supports the Israeli government’s view that the entire population of Gaza should be punished right up to the point of starvation. And the audience of Israel supporters in the US actually applauded him. Other US politicians and commentators have followed suit without any outcry at all, let alone at the level reserved for Helen Thomas when she said objectionable things about Israel.

In an interview, historian Tony Judt expresses his views on the long-term danger to Israel of depending on the unconditional support of the US and discusses how its current psyche of victimhood came into being.

In the case of both Israel and Iran, we see how easy it is for two countries that once showed promise of becoming liberal democracies to be steadily driven away from that under the sway of religious groups. As a result, the future of that volatile region looks exceedingly bleak.

If the appeal of religion is not nipped in the bud before religious groups can gain in strength, it seems like only a matter of time before those groups gain power and influence, with potentially disastrous results.

Liberal democracy and religion-4: The Iranian case study

Iran provides a good case study of how unstable liberal democracies can be when faced with concerted efforts by powerful forces determined to undermine them.

Americans were taken by shock when students occupied the US embassy in Teheran in 1979 and held embassy employees captive for 444 days. Ever since they have been bewildered by references of Iranians to the US as “The Great Satan” and have asked themselves the question “Why do they hate us?”

Liberal democracy and religion-3: The European model

What is happening in Europe is an interesting example of the tension between religion and liberal democracy. The countries in western Europe are only nominally religious. As Dan Barker, co-chair of the Freedom From Religion Foundation, said recently in a talk at CWRU, people in those countries usually enter a church only three times in their lives, and on two of those occasions they are carried in. It is surely no accident that these countries are also stable liberal democracies.

I think that a strong case can be made that lack of religious fervor is a necessary (but not sufficient) condition for liberal democratic values to flourish. The US is perhaps the only country in which fairly strong religious beliefs co-exist with liberal democratic values and this is because of the existence of the first amendment to the constitution which has at least partly managed to keep any single religious group from imposing its will on everyone.

Liberal democracy and religion-2: How to avoid conflict between the two

Based on the examples I gave yesterday, I would argue that religion and liberal democracy are fundamentally incompatible. The reason is that democracy is a system of social organization that is based on rules that are arrived at either by consensus or by some democratic process. The ideals of liberalism are not given by god but have been arrived at over centuries by people trying to find the right balance between personal freedoms and the need for an orderly society. There is no higher authority for any law or constitution than the consent of the governed. If one wishes to change the laws, then one has to persuade ones fellow citizens of the benefits of the change and get them to agree in sufficient numbers.

The laws of religion, on the other hand, are supposedly given by god and usually written down once and for all in some text. They do not usually evolve with the times, except within limits. While there may be some flexibility in interpretation of these laws, they are non-negotiable in principle. The idea that there is a supreme, all-knowing power who knows best and lays down the rules pretty much eliminates the possibility of negotiations and compromise, a bulwark of the liberal democratic process.

Liberal democratic values can flourish only in those countries where religious beliefs are weak or non-existent. As long as religions and religious authorities are kept out of power, then democracy can exist. The problem of religion in liberal democracies is what to do when religious groups threaten to use the processes of democracy to take over the power of government and then impose their religious practices on everyone. When confronted with this possibility, you are forced into a choice between allowing undemocratic forces to exploit the democratic process to force everyone to live in a theocracy with its denial of basic freedoms of democracy, or using undemocratic means (such as banning religious parties) to prevent such a theocratic takeover. Neither of these outcomes is desirable since liberal democracy dies either way.

Is there a solution? I believe that the best thing to do is to not let religion gain a foothold in the first place. The only way to do so that is consistent with liberal democracy is to use our freedom of speech to show that religious beliefs are false, the idea of rights and values given by god makes no sense, and that no reasonable modern person should take religion seriously. If we can do that and make religion less appealing, then it becomes highly unlikely that religious political parties will ever gain power. After all, it is unlikely that any political party today that bases its platform on the sayings of Greek gods will win any elections because those gods have been discredited. It is not necessary to ban the worship of Greek gods or throw its believers in jail because believing in such gods is now seen as ridiculous.

This is where the current accommodationist policy of not criticizing religion, and even praising it for its supposed good qualities, shows its greatest weakness. It actually increases the likelihood of an eventual theocratic takeover by making religion seem like a good thing. What is worse, people bend over backwards to give religious special privileges that other groups don’t enjoy, such as tax-exempt status, and by pandering to religious leaders and practices, thus giving them greater credibility and actually enabling them to get even stronger. When we treat religious beliefs with reverence and act like religion is a force for good, we make political parties based on religion more likely to flourish and grow.

People who seek to avoid offending religious people by not criticizing their beliefs are thus in a bind. They cannot oppose religious political parties because of their religious basis since they claim that religion is a good thing. It is then hard to later turn around and oppose religious groups when they look likely to seize power and impose their religious rules on everyone.

Gideon Levy points out the dangers of increasing theocratization in Israel and of the special privileges that it currently gives to some religious groups, like being able to avoid serving in the military. He places the blame for this squarely on secular people who misguidedly treat religions as deserving of special treatment.

Orthodox society and its leadership should not be blamed for this. The Orthodox and ultra-Orthodox have the right to do everything they can to impose their faith on the secular majority. It’s the secular who are to blame. Just as it’s not yeshiva students’ fault that they are not drafted, but rather the fault of the secular majority that allows this, so it is with the other aspects of our lives. We, the secular people, are to blame for all this. We’re the ones who give in.

Robert Fisk talks about the increasing influence of religious groups in Israel’s military.

Take Amos Harel’s devastating report in Haaretz which analyses the make-up of the Israeli army’s officer corps. In the past, many of them came from the leftist kibbutzim tradition, from greater Tel Aviv or from the coastal plain of Sharon. In 1990, only 2 per cent of army cadets were religious Orthodox Jews. Today the figure is 30 per cent. Six of the seven lieutenant-colonels in the Golani Brigade are religious. More than 50 per cent of local commanders are “national” religious in some infantry brigades.

There’s nothing wrong with being religious. But – although Harel does not make this point quite so strongly – many of the Orthodox are supporters of the colonisation of the West Bank and thus oppose a Palestinian state.

And the Orthodox colonists are the Israelis who most hate the Palestinians, who want to erase the chances of a Palestinian state as surely as some Hamas officials would like to erase Israel.

Fisk is wrong about one point, led astray by his own liberal democratic thinking. There is something wrong with being religious for the very reasons this series of posts makes and which he himself demonstrates in his article – religion and liberal democracy makes bad bedfellows.

This is why it is important in liberal democratic societies for us to prevent such scenarios from unfolding and the way to do that is to use the process of open discussion to show up religion for what it truly is, a waste of time and resources, a holdover of thinking from the dark ages, and a burden on society. If enough people can be persuaded that religious beliefs are useless and that those who hold them are as much holdovers from primitive thinking as astrologers and those who make decisions based on chicken entrails, then it is less likely that political parties based on them will ever be in a position to take over state power. And liberal democracy can be preserved by liberal democratic means.

Liberal democracy and religion-1: Are they compatible?

I have argued repeatedly that science is incompatible with any religion, unless one claims that religion is nothing more than just a grouping of like-minded individuals who feel the need to engage in theological discussions and common rituals, similar to groupings of social and business clubs. As soon as you introduce a supernatural agency that is unconstrained by the laws of science that everything else operates under, you have abandoned the scientific worldview. So the answer to the question of whether religion is compatible with science is a simple ‘No’.
