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.

POST SCRIPT: Last word on flags

Anonymity, pseudonymity, and sockpuppetry

The recent article I wrote in The Chronicle Of Higher Education titled The New War Between Science and Religion generated a lot of interest. The editors told me that it was the most viewed, forwarded, and commented on article for some time. The article dealt with the current debate between the new/unapologetic atheists and the accommodationists, with me taking the former side.

There were also some responses on some blogs, including a critical one on a website called You’re Not Helping. The site’s anonymous author (I’ll assume a man) said that he was an atheist and that the goal of his site was to critique fellow atheists whom he felt were harming the cause of atheism by poor arguments, tone, etc. That’s fair enough. The internet is a fast-moving place and we could all use watchdogs to monitor what we say so that in our haste we do not say things that are not measured. The commenters here often point out when I am in error or go too far off the rails. The criticisms about me on YNH however, though strongly worded, seemed to me to be somewhat confused and so I did not respond, figuring that readers would figure out for themselves who was more credible.

On the pursuit of happiness

On this holiday on the day after independence day, I am posting again a reflection on what to me is one of the most intriguing phrases in the US Declaration of Independence. It is contained in the famous sentence:

We hold these truths to be self-evident, that all men are created equal, that they are endowed, by their Creator, with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.

I have always found the insertion of the phrase “the pursuit of happiness” as a fundamental right to be appealing. One does not expect to see such a quaint sentiment in a political document, and its inclusion sheds an interesting and positive light on the minds and aspirations of the people who created that document.

But the problem has always been with how happiness is attained. And in one serious respect, the suggestion that we should actively seek happiness, while laudable, may also be misguided. Happiness is not something to be pursued. People who pursue happiness as a goal are unlikely to find it. Happiness is what happens when you are pursuing other worthwhile goals. The philosopher Robert Ingersoll also valued happiness but had a better sense about what it would take to achieve it, saying “Happiness is the only good. The place to be happy is here. The time to be happy is now. The way to be happy is to make others so.”

Kurt Vonnegut in his last book A Man Without a Country suggests that the real problem is not that we are rarely happy but that we don’t realize when we are happy, and that we should get in the habit of noticing those moments and stop and savor them. He wrote:

I apologize to all of you who are the same age as my grandchildren. And many of you reading this are probably the same age as my grandchildren. They, like you, are being royally shafted and lied to by our Baby Boomer corporations and government.

Yes, this planet is in a terrible mess. But it has always been a mess. There have never been any “Good Old Days,” there have just been days. And as I say to my grandchildren, “Don’t look at me, I just got here.”

There are old poops who will say that you do not become a grown-up until you have somehow survived, as they have, some famous calamity — the Great Depression, the Second World War, Vietnam, whatever. Storytellers are responsible for this destructive, not to say suicidal, myth. Again and again in stories, after some terrible mess, the character is able to say at last, “Today I am a woman. Today I am a man. The end.”

When I got home from the Second World War, my Uncle Dan clapped me on the back, and he said, “You’re a man now.” So I killed him. Not really, but I certainly felt like doing it.

Dan, that was my bad uncle, who said a man can’t be a man unless he’d gone to war.

But I had a good uncle, my late Uncle Alex. He was my father’s kid brother, a childless graduate of Harvard who was an honest life-insurance salesman in Indianapolis. He was well-read and wise. And his principal complaint about other human beings was that they so seldom noticed it when they were happy. So when we were drinking lemonade under an apple tree in the summer, say, and talking lazily about this and that, almost buzzing like honeybees, Uncle Alex would suddenly interrupt the agreeable blather to exclaim, “If this isn’t nice, I don’t know what is.”

So I do the same now, and so do my kids and grandkids. And I urge you to please notice when you are happy, and exclaim or murmur or think at some point, “If this isn’t nice, I don’t know what is.”

Good advice.

POST SCRIPT: More on flag fetishes

There were some interesting and informative comments on my post on flag fetishes.

One rule about the proper treatment of the US flag that is routinely violated is the use of the flag design on clothes. You can see this photo album of celebrities wearing the flag design on bikinis and underwear.

Flag fetish

As we approach the independence day holiday with its orgy of patriotic fervor, I want to remark on one of the things that I find curious about America, and that is its flag fetish. People seem to treat the country’s flag with a level of veneration that I find somewhat bizarre. There even exist statutes that spell out in incredible detail how the flag should be treated such as how and when the flag should be raised and lowered, how it should be carried or folded, how old flags should be destroyed, and so on. All the rules of etiquette surrounding the flag are incredibly complex and June 14 has even been designated as Flag Day. Most people, I suspect, are not aware of many of these rules such as, for example, that the flag should never be used as wearing apparel, should never touch anything beneath it, such as the ground, the floor, or water, should never be carried flat or horizontally, and so on. Even the Bible does not get this level of special treatment.

The cycle of abuse and injustice

I recently read the book The Zookeeper’s Wife by Diane Ackerman. This is a story of Warsaw during the German occupation of World War II, told through the eyes of Antonina, the wife of the Jan Zabinski, the head of the Warsaw zoo. They both worked for the Polish underground and over several years sheltered in their villa over three hundred Jews as they tried to escape from the ghetto and get to freedom. The book is based on the diary of Antonina and recounts the tales of the refugees and of the animals under their care. It gives some first person insights into what life was like under Nazi occupation and during the Warsaw uprising.

One thing that I learned from the book that I did not know before was that “the Nazis were ardent animal lovers and environmentalists who promoted calisthenics and healthy living, regular trips into the countryside, and far-reaching animal rights policies as they rose to power. Goring took pride in sponsoring wildlife sanctuaries (“green lungs”) as both recreation and conservation areas, and carving out great highways flanked by scenic vistas.” (p. 86)

The well-known obsession of the Nazis about racial purity also extended to the animal kingdom and they had a particular interest in exotic species that generated some weird ideas, such as trying to bring back to life ‘pure-blooded’ species that were now extinct. In pursuit of this goal, they raided zoos in the countries they occupied, in search of animals that most closely resembled extinct animals so that they could do breeding experiments with animals that showed specific desirable traits. Lutz Heck, the director of the Berlin Zoo, was a key advocate of this idea.

Heck’s reasoning went like this: an animal inherits 50% of its genes from each parent, and even an extinct animal’s genes remain in the living gene pool, so if he concentrated the genes by breeding together animals that most resembled an extinct one, in time he would arrive at their purebred ancestor. The war gave him the excuse to loot east European zoos and wilds for the best specimens. (p. 80)

During the occupation, the people in Warsaw received rations of bread that were carefully calculated: Germans got 2,613 calories per day, Poles 669 calories per day, and Jews 184 calories per day (p. 104). No doubt German scientists had calculated precisely the minimum calories needed to maintain life. The Nazis also believed in the abominable practice of collective punishment, where in response to an act by a single individual, retribution was immediately meted out to the members of their family and even the extended community. “[I]n Poland harboring a Jew was punishable by immediate death to the rescuer and also to the rescuer’s family and neighbors, in a death-frenzy deemed “Collective responsibility”.” (p. 116)

In reading this I was struck by how Israel now practices collective punishment in the occupied territories by imposing a policy of restricting food supplies to the people of Gaza and also committing such acts as bulldozing the homes of the extended families of anyone suspected of any terrorist action.

In response to my series of posts denouncing the Israeli siege on Gaza and the attack on the relief flotilla, one commenter defended Israel’s actions and produced data suggesting that the physical health of Gazans was not that bad compared to people in some other developing countries. I did not respond to that comment, thinking that most readers here would recognize that you cannot justify a policy of deliberately restricting food reaching people merely by saying that other people are worse off. The point is that willfully brutalizing people, deliberately keeping them hungry and miserable, and denying them basic due process is wrong, whether or not the targets of such actions look emaciated as a result. Deliberately denying entire populations of people equal access to food and medicine and other staples of life based on their ethnicity, religion, or nationality is simply monstrous, whether done by Germans to Poles and Jews or by Israelis to Gazans, and also irrespective of whether any single groups receives minimal amounts.

Reflexive Israel supporters like Senator Chuck Schumer said, to enthusiastic applause from other Israel supporters: “And to me, since the Palestinians in Gaza elected Hamas, while certainly there should be humanitarian aid and people not starving to death, to strangle them economically until they see that’s not the way to go, makes sense.” He should be roundly condemned for these disgusting remarks. He seems to think that collectively punishing an entire population because he does not like who they elected is just fine as long as the people of Gaza have just enough food so as not to starve to death. And this man is a US senator. Why are there no widespread calls for him to resign?

You would think that any people who have suffered harsh injustices at the hands of others and know what it feels like would resolve to prevent such acts anywhere to anyone in the future. But the sad truth is that not only do they not oppose such actions, they even inflict them on others, perpetuating the cycle of injustice and oppression. We find on a collective scale the cycle we see in individuals, where the victims of abuse often become abusers themselves.

The US was born of anti-imperialist sentiment but that has not prevented it from becoming an imperialist power now, applying brute force on country after country. When I see the hateful anti-immigrant rhetoric and actions that are being used against Hispanic people, I often wonder if this does not originate in fear. Some whites may think that when white people in America become a minority, as they are projected to do sometime in the not-too-distant future, they may be treated as badly as they treated minorities.

The cycle of abuse and injustice must be broken. The only way to do that is to break free of the sense that allegiance to our particular tribe (whether ethnic, religious, or nation) is more important than our allegiance to human rights and justice.

POST SCRIPT: Brilliant Marcus Brigstocke rant on the three Abrahamic faiths

It is hard to disagree with anything he says.

Is cheerleading a sport?

In the seminar that I teach that deals with scientific revolutions, one of the difficult questions that we grapple with is how to distinguish science from non-science. In other words, if we have two boxes, one labeled ‘science’ and the other ‘non-science’, can we establish some criteria that will enable us to take any given theory and determine which of the two boxes it should be put into? To be able to do so requires us to establish the existence of both necessary and sufficient conditions for something to be considered science.

If we have only necessary conditions, then any theory that does NOT meet those criteria is definitely not science so it goes into the non-science box. But if it does meet just necessary criteria, all we can say about it is that it may or may not be science. i.e., we do not know which box to put it into. So for example, the commonly accepted idea that scientific theories are materialistic and generate predictions that can be tested are necessary conditions. This is why any theories involving supernatural entities or that are untestable tend to be immediately classified as non-science. But all theories that are materialistic and testable may not be science. For example, the idea that soccer fans are intrinsically rowdier than football fans is not a scientific theory (in the usual sense we use the words) although the methods of scientific investigations (such as statistical analysis and correlations) may be used in seeing if it is in fact a true statement.

Similarly, if we have criteria for sufficiency and a theory meets those criteria, then it goes into the box marked science. But if it does not meet the criteria, it may or may not be science, so again we do not know which box to put it into. As an example, if we say that a theory is science if it has been cited as the reason why its inventors were awarded a Nobel prize, then quantum theory would be scientific without a doubt. But what about the theory of relativity? It has not been cited in Nobel awards so by our rules we cannot definitely say if it is or is not science.

This is why we need BOTH necessary and sufficient conditions to be able to make unambiguous statements that theory A is science while theory B is not science..

One would think that it might be easy to simply make a list of necessary conditions and say that if a theory meets ALL of those necessary conditions, then that is sufficient. But it is not that simple. What complicates things is that any demarcation criterion that tries to distinguish science from non-science would have to be such that all theories that are commonly accepted as science (such as Newton’s laws of motion) would meet the criteria and be included while those that are commonly thought to not be science (say astrology) are excluded. Trying to ensure that existing theories go into the correct boxes is where the difficulty arises because there are always difficult marginal cases.

Finding necessary and sufficient conditions for science has been so difficult that some have declared this problem to be either insoluble or not worth the effort to solve it.

In teaching these somewhat abstract concepts of necessary and scientific conditions, I try to give my students a more down-to-earth parallel by posing to them the question: Is cheerleading a sport? This usually generates a lively discussion and they soon realize that in order to answer this question, they need to arrive at necessary and sufficient conditions for what makes something a sport or non-sport and they quickly discover that it is hard, if not impossible, to do so. And the difficulty is exactly the same as that confronting demarcation criteria for science. While it is possible to make prescriptive lists of conditions for what constitutes a sport, what complicates things is that whatever conditions we arrive at should also be such that things that are commonly accepted as sports (say tennis and soccer) and those that are not (drinking a beer or taking a nap on the couch) fall, using those criteria, into the correct boxes. And there are some tough marginal cases, not just cheerleading. Is chess a sport? Is the card game bridge a sport? (Both have applied to be part of the Olympic games.) How about video games?

It turns out that my classroom discussion question of whether cheerleading is a sport is not a purely academic exercise. It is actually being argued before a federal judge in Connecticut. The reason is that Quinnipiac University has been accused of subverting the requirements of Title IX, the federal legislation that requires colleges to provide some level of equity in support of women’s athletics. The university cut costs by classifying the high-numbers, low-cost, women-dominated cheerleading as a sport, enabling them to eliminate other women’s sports (such a volleyball) that cost more per student. The women’s volleyball team has challenged the university’s classification of cheerleading as a sport and this is what has led to the lawsuit.

In arguing the case, we see the same necessary and sufficient arguments surfacing.

While physical effort and ability are a given for many of the high-level gymnasts who cheer, Title IX has specific criteria for what counts as a sport when it comes to equity in athletics: a program must have a defined season, a governing organization, and feature competition as its primary goal. Competitive cheer is not recognized by the National Collegiate Athletics Association (NCAA) as a sport. Nor does it have a governing body: two versions of organizations that have filled the role have been associated with Varsity Brands, Inc., a for-profit company that sells cheerleading gear and hosts up to 60 “national championships” a year. To amplify its case that competitive cheer can indeed count as a varsity sport, Quinnipiac has joined with seven other schools to form the National Competitive Stunts and Tumbling Association, which is intended to be a new governing body for the sport. Four more schools need to sign on for it to be recognized as a legitimate governing body, and the sport itself to be seen as “emerging.”

It looks like what Title IX has tried to specify are just necessary conditions which, as we have seen, can only definitely say if cheerleading is not a sport. It is not clear if it says that if an activity meets ALL the necessary conditions, then that is sufficient to make it a sport.

Whatever the outcome, Quinnipiac University should be ashamed of itself for trying to subvert the spirit of Title IX and eliminating women’s volleyball.

But what I am really curious about is how the judge is going to arrive at a verdict. Will he be able to specify necessary and sufficient conditions and thus arrive at demarcation criteria, something that has so far eluded my students and me? If so, I will gladly say that you’re a better man than I am, Gunga Din!

The rotten US health care system

Just last month I went for a routine physical examination followed up by routine blood tests and a bone density scan. According to my health insurance plan, all these were supposed to be fully covered. Of course, being a veteran of the bureaucratic health care system in the US, I know that nothing is ‘routine’ here and so before I did any of these things I had to spend some time making sure that I was going to a doctor covered by my insurance plan and that the blood-testing laboratory and the bone-density measuring facility were also covered procedures done by approved facilities.

What the McChrystal affair reveals about the media

One initial reaction of the mainstream media to the Rolling Stone article that got Stanley McChrystal fired as commander of US forces in Afghanistan seemed to be “Rolling Stone? Rolling Stone?” They couldn’t understand why the person in charge of the war in Afghanistan gave so much access to what they saw as a hippy-dippy magazine that mainly covers rock music and popular culture. The issue with the McChrystal article had Lady Gaga on the cover and, as you can see, the article in question did not even get top billing, suggesting that the magazine itself did not realize what its impact would be.
