The end of religion?

A provocatively-titled article came across a social media site today and caught my eye. In "Religion may not survive the Internet", Valerie Tarico lists several reasons why conservative religions are threatened by information flow. That - the free exchange of ideas and instant communication -  not the internet per se, is more accurately the threat, if any, to the survival of certain belief systems.

Religion has been with humankind for at least some 20-30 thousand years, if interpretations of cave art in southern Europe are correct. Given its long history and the high percentage of people that still identify with some religious tradition in the 21st century, I do not think it is going anywhere anytime soon. Thus, Tarico's title is hyperbole. However, she does raise some interesting points in the article:

(1) The mechanisms (overt, covert, intentional or otherwise) that some religious traditions have relied on to maintain homogeneity of belief may not be as effective in an age when information can flow much more freely than ever before. Insularity may be one such mechanism. When people form cohesive groups that more or less cut off discourse with the outside world, it may be easier to maintain certain religious beliefs. It is hard to know how much this really goes on today. It would seem that in our information age virtually everyone would be exposed to just about any set of ideas. However, even in a sea of information, are some people so selective in what they read or hear that they very rarely encounter perspectives that contradict their own beliefs?

I think that Tarico's misstep is to equate this free-flow of information with the internet. Yes, the internet has accelerated the pace of information exchange, but information exchange has been possible for a long time by a number of different vehicles. The data on evolution, for example, have been out there for some time. It just required more work to find it in the past. She also seems to indict religion generally, but some of her arguments probably only apply broadly to more fundamentalist religions traditions. I see the free flow of information as a threat mostly to religious systems that are adament about doctrinal orthodoxy.

One potential causalty of information exposure is religious literalism. Specific narratives like Noah's Flood have no credibility scientifically. A young curious mind raised on stories of Noah (and mind you, curiosity is a key variable in the equation!), isn't going to find much support for such traditional religious ideas in information from the outside world. At risk too, are antiquated social constructs that are an important part of a specific religious tradition but which cannot withstand the scrutiny of empirical evidence or informed discussion. Being a gay blog, I'll mention homosexuality here as an example. When, by the freer flow of information, people find out that gay people are often law-abiding, charitable and accomplished citizens, or that practically to a person gay people relate that they never "chose" their sexual orientation, an archaic belief that homosexuality is a Satan-inspired threat to humanity becomes very hard to sustain.

The solution for religious systems in an age of information overload is simply to adapt. My guess is that many mainstream religions are doing so - they learn to embrace science, evolution, rational inquiry, and increasing social equality. Religions, like languages and genes, must evolve to survive.

(2) Tarico points out that science represents a threat to religion, and not just because it might directly contradict certain religious claims. She writes:

"Religion evokes some of our most deeply satisfying emotions: joy, for example, and transcendence, and wonder....Fortunately, science can provide all of the above...[thus] it should be no surprise that so many fundamentalists are determined to take down the whole scientific endeavor. They see in science not only a critic of their outdated theories but a competitor for their very best product, a sense of transcendent exuberance." (1)

I think that these thoughts are the highlight of the article. Religion's most powerful claim to its continued value for humanity is it's ability to provide a transcendent experience for individual believers. If that transcendence can be achieved elsewhere - in a classroom, in nature, through a microscope - then one of the most important functions of religion is lost.

In my own experience this makes a lot of sense. As a scientist I find such fascination in the natural world that there seems no need to call upon the supernatural. Whether ecology, geology, or the diversity of life, I find such an unending wealth of questions and discoveries that I can connect with the broader world around me in profound ways. Steeped in science, I am left to feel miniscule - much like I would by believing in an all-powerful God who watches over me. Yes, I am still swayed by the need for love and purpose - intangibles that science may have little to say about - but I've also found that specific religious systems are not necessary to appreciate and seek after such things.

Religion seems to be here to stay. Yet I do hope that it will continue to evolve to be a more rational and loving human enterprise. Maybe the internet will be part of accelerating that process. Thoughts?

When the improbable is compelling (Part IV)

In a 2007 interview for a PBS documentary about the LDS Church, the late President Gordon B. Hinckley said: “[Our foundation] is either true or false. If it’s false, we’re engaged in a great fraud. If it’s true, it’s the most important thing in the world. Now, that’s the whole picture. It is either right or wrong, true or false, fraudulent or true.” As President Hinckley succinctly stated, Latter-day Saints are taught to accept the Church as a bundled package. There isn’t much middle ground (according to the official viewpoint at least). There is little room for people like me that are inclined to believe about 44% of Mormonism (1).

A lot of modern Christians do not regard belief as such an all-or-nothing proposition. They might look at the contradiction between a literal belief in Genesis in the Bible and current understanding of human history and evolution and choose the latter while enjoying the other benefits of their faith. They may not believe in a literal bodily resurrection of Jesus, but rather view that story in a figurative capacity, whose main purpose is to teach spiritual truths. Because of this doctrinal selectivity, they might be called ‘Cafeteria Christians’. Such fragmentation of belief really doesn’t exist in orthodox Mormonism. It isn’t where Church leaders want members to go.

Belief and compliance are pretty central to Mormonism. The LDS embodiment of belief is a 'testimony'. A testimony is both a public affirmation of belief and a very private affair. Any visit to a testimony meeting (traditionally held on the first Sunday of each month), confirms the central role that testimony plays in Mormon identity and mindset. In these meetings, individual Mormons from the congregation volunteer to share a brief witness of their beliefs to the whole congregation. Testimony meetings are a form of encouraged confirmation bias. When testimonies are shared, the verb ‘know’ is usually used in place of ‘believe’. Even young children will share statements before a congregation such as ‘I know Joseph Smith was a prophet’. Mormons are promised that their testimonies will grow as they share them. The testimony is sacred in Mormonism. It is nourished, protected and shared. Its arch nemesis is doubt.

Mixing testimony, LDS social dynamics, and the strong claims of divine Church origins creates a distinct Mormon fingerprint regarding belief. This common pattern of belief (with individual variation, of course) creates a number of interesting phenomena in Mormon culture. The first is an interesting linkage between faith and personal righteousness (typically termed ‘worthiness’). Doubt is viewed negatively, and while perhaps not a sin technically, it is seen in Mormonism as a weakness. Church leaders have taught that faith and doubt do not co-exist in the same mind simultaneously (2). Members seldom express doubt about Church teachings in public settings. A very prevalent adage says that ‘The Church is perfect but the members are not’. The Mormon linkage between faith and worthiness is also manifest in interviews between lay members and ecclesiastical leaders to determine worthiness to enter into the temples of the Church. In addition to questions about sexual purity, honesty, and abstinence from alcohol or tobacco in these interviews, members are asked if they have a belief in the restoration of the Church, a belief in the Godhead (trinity) and if they affiliate or sympathize with views or organizations that are contrary to official doctrine. So even though doubt can be an important prerequisite for refining human understanding, it is given poor treatment in Mormon culture. In my more skeptical moments, I find the heavy emphasis on certainty in Mormon discourse to be nauseating.

Secondly, criticism of the leadership is viewed very unfavorably in Mormonism. Because the upper hierarchy of the Church is seen as the connection between God and the rest of humanity, these men occupy a distinct position of respect in the theology. Their teachings are often seen as infallible because they come from God. Leaders may from time to time encourage this special deference to their position and viewpoints (3). Furthermore, in LDS temples Mormons make a covenant to avoid “evil speaking of the Lord’s anointed”. At the very least, this culture of deference to authority tempers public expression of alternative doctrinal viewpoints in the Church. In Mormonism, revelation and doctrinal exposition are top-down processes which are closed to significant debate among the lay membership.

Another interesting effect of LDS belief patterns on member behavior is a tendency for some members of the Church to engage in self censorship (4). Because faith is linked with righteousness and one’s standing in the faith community, there is a strong incentive to protect the integrity of that belief system. Many members avoid reading “anti-Mormon literature”, a term that can encompass anything that speaks negatively about the Church. Other members may avoid specific academic subjects that are likely to contain ideas that threaten their testimony of Mormonism. Those could include anthropology, cosmology, evolution or archaeology. More subtly, much spiritual energy can be spent by some members trying to protect their testimonies. I speak of this from experience, having spent many years putting doubts aside, or giving uncomfortable doctrines the benefit of the doubt. A recent study found that BYU professors in fact, in large proportion, avoided researching topics that may put them into conflict with the Church (5).

A final curiosity about the fingerprint of Mormon faith is the phenomenon of apologists in the Church. Apologists seek to sustain and promote official or traditional viewpoints of the scriptures and Mormon beliefs and history by engaging in scholarship. Organizations such as FARMS produce academic works with the purpose of supporting Mormon ideology and history. While these academics may be trained in scientific methodology and do careful detailed research, they may not always approach their subjects in a scientifically-sound manner. Apologists tend to find evidence for questions for which they think they already have the answer. This type of scholarship can be more of a scavenger hunt that an objective enterprise that starts with more open-ended questions. The answer precedes the evidence, not the other way around as should be the case in science. My brief experience with Mormon apologist writings suggests that they can get lost in a forest of details. They may write lengthy papers abounding in footnotes about a single inscription on an ancient stone in Central America in search of credible evidence for Book of Mormon historicity, all the while ignoring abundant DNA and archaeological data that give little credence to a literalist Mormon view of ancient history.

All of the tough stuff of Mormonism – the polygamy and polyandry, similarities between the temple endowment and Masonic ritual, racist policies prior to 1978, multiple and incongruent accounts of Joseph Smith’s first vision, Biblical literalism, the historicity of the Book of Mormon – can put the traditional testimony in jeopardy. Of course members try to deal with these challenges in one way or another (as long as they are aware of them in the first place). Apologists may devise convoluted explanations to support implausible Mormon concepts and rank and file members may just put these questions on a mental shelf filed under ‘unknown’. But in all of the effort devoted to maintain the traditional testimony, I’ve come to believe that other mental values like open-mindedness, intellectual parsimony, and even common sense can get pushed to the wayside. If I had not been a participant in these mental gymnastics myself for some time, I probably wouldn’t be so critical about how more orthodox Latter-day Saints sometimes approach questions of truth.

Not all Latter-day Saints are literalists, and certainly not all are apologists. I am acquainted with individuals who express doubts (even if generally only in private conversation). Other people have let those doubts hold enough sway that they have more or less left the Church all together. But I think it is the core population of Mormonism – those who diligently attend the temple and most of the leadership in the Church – that really believes in the whole package. At least they have convinced themselves that they should believe, because a faithful Mormon is a good Mormon.

In my opinion this black and white view of the world, flavored with the supernatural, breaks down for many people with time. The exit from orthodoxy may start as a simple willingness to ask some hard questions about Church history or specific Mormon beliefs. If the skepticism is coupled with investigation, members are likely to encounter a lot of new information that is at odds with official positions of the Church. It can be time consuming (and perhaps impossible in some cases) to thoroughly investigate all the claims that challenge orthodox Mormonism. But for me at least, the list of concerns and improbabilities began to grow so long and comprehensive that it seemed ever less plausible that Mormonism as a complete package could accurately reflect ultimate truth.

I’ve beat up on Mormonism a fair amount in this post. However, I think it is important to discuss these weaknesses because they are seldom articulated in Church settings. I ask my readers to interpret my criticisms as manifestation of many years of frustration finally venting a little in a public setting, not as blanket condemnation of the Church. Personally, I spent too many hours being silent in church when I was uncomfortable with the certainty, skeptical about the miracles, or dissatisfied with the conformity. My cynicism here doesn’t reflect the totality of my experience with Mormonism; I’ve written briefly about some positives here. Optimism, hard work, service, honesty, sacrifice and a knack for attracting highly motivated and generous individuals are the better fruits of Mormonism.

In this series of posts I’ve discussed tensions between religion and science. Both endeavors make positive contributions to humanity. Belief is a powerful force in the human experience. It can inspire acts of charity. It can bring people together and fuel the flames of optimism. But when incongruent with the truth or used as a social or political weapon, it can lead to dark manifestations of human behavior. When religious tenets and empiricism are in conflict, I’ll side with science with the understanding that it too changes and grows with time and new discoveries. More so than the data it uncovers, it is the method of science that I think has the most to offer all of us seeking truth. The scientific method is self-correcting, progressive, and democratic. Because there is the tendency to hold tightly to the past, religion can use some good housecleaning. It is time to refurbish the improbable and unscientific rooms of religion for a less cluttered and more useful place for the soul to take refuge.

1. Somewhat arbitrarily-chosen number. :)
2. See the Lectures on Faith and this article by President Monson.
3. For example, in 1985 Elder Oaks cautioned against “criticiz[ing] or depreciat[ing] a person for the performance of an office to which he or she has been called of God. It does not matter that the criticism is true.” He stated the following year that, “The counsel against faultfinding and evilspeaking applies with special force to criticisms of Church leaders.” Lavina Fielding Anderson chronicled this and other similar statements by Church leaders that discourage intellectual non-conformity or criticism of Church leadership.
4. Censorship is institutionalized to a small degree in the Church as well. At least when I served in the 1990s, missionaries were encouraged to read only from the scriptures and a few pre-approved religious texts. Church members leading classes are admonished to only use a very limited set of Church-approved materials in their instruction. Such homogenization of Church instruction across the world is known as “correlation”, a somewhat Orwellian term and process that may be administratively efficient but one which may significantly suppress theological diversity within Mormonism.

An eye-opening statistic from this report: when asked if “BYU professors should not conduct even sound research that may draw into question church or university procedures”, 66.1% of respondents from a randomly-selected sample of faculty answered that they agreed or strongly agreed.

When the improbable is compelling (Part II)

Science and religion, perhaps more than any other disciplines of the human mind, concern themselves with the search for truth. Sometimes they often come to radically different conclusions. Yes, they sometimes ask different questions, but their differing destinations can also be explained in large part by different processes of inquiry.

Science is based on empirical research. The process begins with a question, usually born of some set of observations made about the natural world. Humans are generally curious creatures and have long asked about natural phenomena. In science, these questions, which initially may be narrow or wide in scope, are later framed as testable hypotheses. Hypotheses themselves are usually quite specific. They are educated guesses about the mechanisms that create observable patterns. As an illustration (using my field of ecology), one might ask why a tree species is distributed only at certain elevations in a particular mountain range. Hypotheses are then developed: seasonal snowpack limits its upper distribution or competition with another tree species sets its lower distribution. One or more experiments (a set of observations or manipulative interventions) are designed so as to lend evidence to two or more alternative outcomes to the experiment. Ecologists like me love to do field work, so given the hypotheses mentioned above I might set up a clearing experiment to test for evidence of competition or add or remove snow to test for its effects on seedling success (a challenging experiment indeed given the size of the organisms of interest!).

Importantly, good experiments are not structured to automatically favor one alternative hypothesis over another. They are also most helpful when their results can be cleanly interpreted. My mountain experiments with the tree species would need to be conducted so that the experimental methods do not bias the outcome or so that my interpretation is inadvertently stymied by some confounding factor. Broadly speaking, science is not supposed to start with an a priori answer to which subsequent inquiry must be subservient.
Science is guided by a few other key principles. First, science proceeds as hypotheses are rejected. Technically, hypotheses are never proven, rather they are rejected. Second, data and conclusions obtained by good science are repeatable. Incorrect hypotheses will be repeatedly rejected by independent experimentation. A series of experiments testing the same phenomenon with the same approach and under the same conditions should yield the same result. If results differ, the original ideas need to be modified. There are limits to our ability to repeat experimentation, such as the impossibility of rewinding the clock to replicate the exact conditions of a previous time period. But if not for every tiny detail, there are abundant opportunities to verify the general phenomena elucidated by scientific inquiry. Third, science is based heavily on probabilities because it frequently relies on statistics to reach conclusions. Since probabilities govern interpretation, again, hypotheses are not technically irrefutably proved.

Finally, science is pretty democratic. By this I mean that the process of scientific inquiry and the discoveries of science are available to everyone. Limitations of access to expensive instrumentation being one exception, anyone can design and conduct an experiment or gather a set of observations to address a question of interest. Likewise, much of science is conducted in an open manner so that the results of experiments, mathematical models, and observational studies are accessible to all. Scientific results are often published following peer-review (an imperfect though workable process) and then are made available to other scientists and the public for scrutiny, further evaluation, rejection, or modification.

Those basics form the backbone of the scientific process. From here, there are minor philosophical variations on how hypotheses are treated and how science proceeds. Previous theory and data informs the scope of experimentation and the methodology used to address specific inquiries in science. However, the best scientists are open to new results that challenge their existing knowledge about the world. Data are always > theory. In this sense, science has less of a tendency to create a hierarchy of truth: a sound experiment that overturns a well entrenched idea would be accepted even if the original idea came from a scientific superstar. There are no prophets in science with an unassailable conduit to truth. Although incorrect paradigms can persist for some time in our understanding of the natural world (the rejection of continental drift in geology until about the 1960s is a good example of stalled progress), science can also be punctuated by paradigm-shifting breakthroughs that rapidly push forward inquiry by providing a new framework of understanding (1). Creativity, hard work, collaboration and intelligence are generally the main ingredients of successful science.

Empirical research, like any human endeavor, has limitations. One fundamental issue concerns limits to observation. Tools such as microscopes, telescopes, satellites, and high speed computational statistics extend our capacity to measure and model phenomena at smaller and larger scales than are possible with human senses, but they only extend perception so far. Another limitation to empirical science is that some concepts are largely untestable. “Hypotheses” such as the existence of supernatural beings or miracles cannot be adequately addressed with typical scientific techniques. Even for many natural phenomena rarities abound. It may be logistically impossible to repeat experimentation or observation of extremely rare events. Yet this does not mean that all religious claims about the supernatural are off the hook intellectually; the lack of ability to test certain religious ideas empirically also means that we can never reject natural explanations in favor of the supernatural.

Religion seeks knowledge by a wide diversity of means. In many religions, ancient scriptural texts derived through others’ interactions with the divine form the basis of acquiring truth about life, history, human purpose and moral responsibilities. Many religions place importance on a living authority – a prophet or teacher – whose role is to transmit divine information. Yet other religions, particularly Zen Buddhism, focus on individual experience with truth. Meditative practices enable direct communion between the religious student and the divine (truth). Mormonism has pieces of all of these basic means of discerning truth.

While religion can have deep inspirational value for human beings, its several pathways to knowledge each suffer from significant weaknesses. First, ancient religious texts have cultural biases and tend to have limited scientific rigor because they were composed in less scientific times. Add to these translation issues, indeterminable textual origins, uncertain dating, and incongruence between textual claims and empirical findings and their reliability as a source of infallible truth becomes very suspect. Moreover, we generally know nothing about the authors of ancient religious texts outside of the information presented in the works themselves; are these people reliable sources of information? Have their words and experiences been changed by others unintentionally or intentionally? At best, concepts in religious texts should be treated as hypotheses, subject to debate or scrutiny like any other claim.

Individual experience and spiritual teachers are also common means of acquiring religious truth, but they suffer heavily from the vagaries of subjectivity. The experiences, thoughts and inspiration each religious seeker obtains are invariably influenced by culture, individual circumstance, and personality. Religious seekers and proponents can hold more ennobling traits like compassion, selflessness and mental discipline, but they can also be subject to greed, deception, the quest for power and jealously like the rest of us. In my view, I assume that spiritual experiences are principally cerebral experiences, so how can the inner thoughts of another person ever be verified? There is no ability to challenge spiritual interpretation that comes through authority the way that an open scientific process allows. For these reasons, accepting others experiences as divine truth of direct relevance and applicability to me, something I am hesitant to do.

Theoretically, any of the fundamental features of the scientific process – observation, hypothesis generation, experimentation, and replication – can be applied to some religious questions. In fact, in the Book of Mormon a notable series of passages encourages non-believers to “give place that a seed may be planted in your heart …”, a sort of experimentation with faith in religious concepts (see Alma 32:27-42). The reasoning is sound: if the religious claims are true, then they experimentation should yield consistent and positive fruits. But caution is still warranted: if in taking a placebo, I feel better, without careful scrutiny I would not know that there was some mechanism other than the substance of the pill itself that had its effect on me.

More to the heart of a skeptic’s point of view, there are instances where scientific approaches can be applied to religious claims. I find these exciting, because they are one way to evaluate the reliability of religious sources. The most prominent of these questions in Mormonism are specific historical events. Claims in the Book of Mormon such as Israelite journeys to the Americas and cataclysmic destruction of ancient cities are subject to verification by archaeology and studies of human phylogeny. A subject better left for its own post, scientific evidence seems relatively scant for many traditional Book of Mormon claims. DNA evidence, for instance, is highly unfavorable towards the popular LDS view that many of the Native Americans descended from Middle Eastern populations several thousand years ago (2).

Religion need not have antipathy towards science. Skepticism about supernatural claims is healthy. Unfortunately, some elements in religion are hostile to scientific inquiry. Some biblical literalists, for instance, hold that scripture comes directly from God, and is therefore intellectually unassailable. Scriptural teachings are like a perfect scaffolding around which other elements of truth must eventually fit. Such scaffoldings can often demand a lot of mental gymnastics. If they are not based on truth, they will eventually fall. In my view, science and religion best co-exist when religion humbly accepts that many questions about life and human experience are better addressed by empirical inquiry. Religion can be a powerful force in teaching ennobling ethics and encouraging the human spirit to flourish. It oversteps its bounds however, when it deals with evolution and not ethics, linguistics and not love.

2. Simon Southerton presents a very interesting discussion of DNA and the origins of Native Americans in this Mormon Stories podcast. Similar information can be found on his blog. The DNA issue, in my view, is extremely troubling for many of the traditional claims of Mormonism.
