Neuro-Nonsense: The Perils, and Promise, of Cognitive Science for the Study of Religion

imgresThis is the text of a paper I presented at “The Psychology of Religion/Religion of Psychology” conference held at the University of Chicago Divinity School  on March 6, 2015.  My paper was the first in a panel devoted to “Disjunctions Between Contemporary Psychology and Religion.”

On July 17, 1990, President George H.W. Bush announced in Proclamation 6158 that the 1990’s were to be officially designated as the “Decade of the Brain.”  The Proclamation began with these lines:

“The human brain, a 3-pound mass of interwoven nerve cells that controls our activity, is one of the most magnificent—and mysterious—wonders of creation.  The seat of human intelligence, interpreter of senses, and controller of movement, this incredible organ continues to intrigue scientist and layman alike.”

President Bush’s Proclamation accelerated scientific efforts to learn more about how the brain works, with a special focus on finding new treatments for devastating neurological disorders like Alzheimer’s and Parkinson’s diseases.  To achieve that goal, powerful technologies were developed to analyze, measure, and influence the brain.  These tools are primarily aimed at addressing the growing medical needs of an aging population, but they have been applied in other areas of research as well, including the psychological dimensions of religion.

Other speakers may talk in more detail about the positive aspects of this turn towards the brain, and so will I.  But first, we should consider the casualties and costs of this historical shift, which has in many ways been disastrous for the psychology of religion.  Three particular losses—of historical awareness, therapeutic engagement, and interest in mysticism—will be the focus of my presentation, which Peter Homans, who taught here at the Divinity School for many years, might have considered a work of mourning, in the sense of responding to loss by the creation of new meanings.  If we can gain more clarity about what has been lost in this field since the “Decade of the Brain,” we can more fairly assess the potential benefits of neuroscientific research for religious studies.  We can also, at that point, consider the potential benefits of religious studies for brain research.

Let me briefly define some terms.

The psychology of religion, as we have already heard, comprises a multifaceted research tradition going back more than 100 years to the pioneering work of Sigmund Freud, William James, Carl Jung, and others.

Cognitive science is an alliance of six disciplines—neuroscience, psychology, computer science, linguistics, philosophy, and anthropology—that together, beginning in the 1970’s and accelerating in the 1990’s, have tried to improve on psychoanalytic and behaviorist models of the mind.

The cognitive science of religion, or CSR, is a 21st century development in the psychology of religion, drawing on contemporary scientific studies of brain-mind functioning.

CSR appeals to many researchers because it emphasizes experimental evidence and testable hypotheses, helping researchers escape the hazy hermeneutics and overly thick descriptions too often found in the contemporary study of religion.  CSR offers a bracing, forward-looking response to the tired and fruitless meanderings of post-modern scholarship.

Unfortunately, the cost of this approach has been a loss of interest in, or even awareness of, the findings of earlier researchers who carefully investigated many of the same topics as those found in CSR.  Anything that happened before the “Decade of the Brain” no longer seems relevant now that we have such powerful neuroimaging tools at our disposal.  This leads to CSR researchers claiming new explanations of phenomena that actually have a long history in the psychology of religion.  This is what Jeremy Carrette has called “disciplinary amnesia,” and our field has a bad case of it.

As a brief example, consider Pascal Boyer’s 2002 book Religion Explained: The Evolutionary Origins of Religious Thought.  This is an admirable work in many ways, and highly influential in CSR, but it takes strangely little account of earlier research in the psychology of religion.  In a passage late in the book Boyer comments on the similarities between religious rituals and obsessive-compulsive disorder (or OCD).  He describes several neuroscientific studies, all conducted in the 1990’s, on dysfunctions in the brain associated with OCD.   Although he does not insist that all religious rituals are pathological, Boyer uses this neurological evidence to support his book’s overall argument that religious beliefs and behaviors are “parasitic” on normal processes of the mind.

I don’t want to engage right now with Boyer’s “mental parasite” theory of religion.  Rather, I want to point out that in two detailed pages of text comparing religious rituals and OCD, Boyer never once mentions Freud, whose 1907 article “Obsessive Actions and Religious Practices” addressed exactly the same topic.  Indeed, Freud’s prescient article was crucial in defining the clinical syndrome of OCD itself, which Boyer now “explains” in CSR terms.

Why does this loss of history matter?  Maybe it doesn’t.  There is an argument to be made that a scientific field should not be overly concerned with or reverential towards its past.  After all, we don’t make people study alchemy before they can start learning chemistry.

But it’s not that simple in the psychology of religion.  Not only does the loss of historical self-awareness lead to unwarranted claims of novel discoveries, it also makes it harder to avoid going down paths that earlier researchers have found to be dead-ends.  Here again, the case of Freud is helpful.  Too few people know or appreciate the fact that Freud was originally trained as a neuroscientist, receiving his education from some of the best medical research institutions in the world at that time.  Freud knew as much about the brain as anyone, and in 1895 he began drafting “A Project for a Scientific Psychology,” in which he planned to use neuroscientific evidence to explain mental life in purely physical terms.  But then, a couple years later, he gave up on this plan, and turned to the study of dreams.  Why did Freud abandon his neuroscientific vision?  Not because he lacked hi-tech brain scanners.  Freud gave up on the 1895 Project because he realized that experimental neuroscience was not enough, and would never be enough, to understand the human mind.  Focusing on the material workings of the brain can only take us so far, before we have to include the analysis of emotion, desire, consciousness, family, culture, and many other dimensions of psychological experience that are difficult to measure or experimentally manipulate.

Paul Ricoeur, in his 1970 book Freud and Philosophy, gave Freud credit for developing a “mixed discourse” between force and desire, energetics and hermeneutics, the workings of the brain and the meanings of the mind.  Freud may have been limited in his view of those forces and desires, but he had the right idea: we need hybrid theories and concepts that can clarify, rather than obscure, the subtle, multidimensional complexities of the human psyche.

This kind of approach has been eclipsed in recent years by the emphasis on brain science as the ultimate source of explanatory truth.  We seem to be going back to a place that Freud abandoned at the end of the 19th century.  It’s worse than just reinventing the wheel, it’s forgetting why we ever needed a wheel in the first place.

The second loss, of therapeutic engagement, reflects another adverse consequence of the “Decade of the Brain.”  Throughout the 20th century the psychology of religion was stimulated by the clinical work of Freud, Jung, and many, many other skilled therapists who delved deeply into the mental worlds of their clients, and in the process gained remarkable insights into the religious and psychological dynamics of their lived experiences.  Both medical psychiatrists and pastoral counselors found useful information here, and their shared interest inspired many fruitful conversations about the role of religion in healthy human development.

In recent years, however, these interpersonal, humanistic practices of therapy have been swept aside and replaced by the increasingly widespread use of psychoactive drugs.  The mental health system, in the U.S. at least, has turned into an impersonal delivery service for prescription medications and short-term cognitive behavioral therapy.  This bears little resemblance to the rich, intimately detailed clinical practices that for so many years were integral to the psychology of religion.

To be clear, many psychoactive drugs save lives and help people stabilize enough to benefit from other treatments.  But the skyrocketing use of these medications has severely undermined the efforts of psychotherapists and pastoral counselors to practice their healing crafts.   Unfortunately I see few people in CSR who regard this as a problem for the field.

The third loss I want to mention regards an appreciation for the multiplicity of religious experiences, from mystical visions and dreams to possession, trance, and ecstasy.  These phenomena are difficult to measure using brain scanning technology, and in any case such “altered states of consciousness” obviously deviate from the mind’s functioning in a normal waking condition—the state to which most psychoactive drugs and cognitive therapies are trying to return a person.  Hence, CSR researchers have tended either to ignore mystical experiences or treat them as pathological failures of normal brain functioning, like bad pieces of neural code. The result is a shallow, homogenized view of human religiosity that excludes precisely those unusual, intensified experiences that William James said more than 100 years ago were key to a psychological understanding of religious life.

On this count we should be no less skeptical toward supposedly “pro-religion” researchers like Eugene D’Aquili and Andrew Newberg, whose brain imaging studies of people in meditation allegedly reveal a common neurological core of all mystical experiences (what they refer to as “absolute unitary being”).  Their claim does not stand up to either empirical or conceptual scrutiny, and yet many people have accepted it because it seems to give a neuroscientific “seal of approval” to the study of mysticism.  This to me is the worst of all worlds: taking poor practices from neuroscience and using them to dumb down the psychology of religion.

So, these three losses, of history, therapy, and mysticism—that’s the bad news of recent years.  But there is good news, too.  For instance, a new branch of research, known as social neuroscience, is taking more seriously the idea that we cannot just study brains, we have to study brains in bodies that live within families, who live within broader social and cultural contexts. It turns out that normal, healthy brain development depends fundamentally on a supportive social environment, on a lively stream of interpersonal relationships.  I know that in the last years of his life Don Browning, who taught religion and psychological studies here at the Divinity School, was having conversations with social neuroscientists in the University, and he engaged with them as Paul Ricoeur might have done, seeking new prospects for a mixed discourse.  Following Browning’s example, I encourage the psychology of religion and CSR to pursue more engagement with this area of brain research.

Still, even the good news has an asterisk attached.  I’ve begun wondering if the appearance of social neuroscience is actually a sign that the brain boom has peaked.  There seems to be a kind of self-deconstructing process at work here.  If we cannot understand the brain without looking beyond the brain, then neuroscience loses its status as an ultimate source of explanatory authority.

The future of the psychology of religion will not, I venture to say, center on brain research, or for that matter on genetics, or evolutionary biology, or the latest findings from any other scientific discipline.  Rather, the future will depend—and I’m sorry, this isn’t going to sound very exciting, but I think it’s true—on data management, meaning our ability to gather, sort, analyze, and creatively integrate information from many different sources.  The Decade of the Brain is over, but the Century of Big Data is just beginning.

I don’t know about each of your different areas of specialization, but in mine the “Moneyball” changes are happening very fast, with torrential volumes of new information and the emergence of amazingly powerful tools of analysis.  In 2009, motivated in large part by a fear of being left behind, I began developing the Sleep and Dream Database, an online digital archive and search engine for empirical dream research.  (With the help, I should say, of software engineer Kurt Bollacker, U.C. Santa Cruz psychologist Bill Domhoff, and his coding colleague Adam Schneider.)  At this point the database includes more than 15,000 dream reports from a variety of sources, including demographic surveys, personal journals, psychology experiments, and historical records.

There are many different analytic paths a psychologist of religion could follow using these materials.  [All of the following examples have links to sample data in the SDDb.]

For example, one could sort through all the dream reports in the SDDb with words relating to religion.

Or, one could look at just the dream reports of people who identify themselves as Born-Again Christians.

Or one could compare the dream recall frequencies of people (American adults) who do or do not consider themselves more “spiritual than religious.”

I mention the SDDb because it is a small but practical example of how to make adaptive use of big data technologies rather than becoming overwhelmed by them.  Of course, there are many limits to this kind of quantitative analysis of what Freud would call “manifest” dream content, along with many questions about personal privacy, interpretive authority, and data security.  But I would like to close my presentation by at least gesturing beyond the critique of neuro-nonsense, and offering the hint of a more constructive response to the question that has drawn all of us here, namely how to promote a more prosperous future in the psychological study of religion.

Thank you.

 

The Origins of Religion in Dreaming

220px-WLA_metmuseum_Bronze_statue_of_Eros_sleeping_7One of the oldest theories about the origins of religion argues that religious beliefs and practices are derived from the experience of dreaming.  This theory is most often associated with the 19th century British anthropologist E.B. Tylor, as expressed in this passage from the 1873 work Primitive Culture:

“The evidence of visions corresponds with the evidence of dreams in their bearing on primitive theories of the soul, and the two classes of phenomena substantiate and supplement one another….That this soul should be looked on as surviving beyond death is a matter scarcely needing elaborate argument. Plain experience is there to teach it to every savage; his friend or his enemy is dead, yet still in dream or open vision he sees the spectral form which is to his philosophy a real objective being, carrying personality as it carries likeness.”

This same idea was also expressed, in even sharper language, by the German philosopher Friedrich Nietzsche just a few years later, in his 1880 book Human, All-Too Human:

“Misunderstanding of the dream. –The man of the ages of barbarous primordial culture believed that in the dream he was getting to know a second real world: here is the origin of all metaphysics.  Without the dream one would have had no occasion to divide the world into two. The dissection into soul and body is also connected with the oldest idea of the dream, likewise the postulation of a life of the soul, thus the origin of all belief in spirits, and probably also of the belief in gods.  ‘The dead live on, for they appear to the living in dreams’: that was the conclusion one formerly drew, throughout many millennia.”

I have just finished writing the manuscript for a book that tries to put this idea to the scientific test.  The book is titled Big Dreams: The Science of Dreaming and the Origins of Religion, and it will be published by Oxford University Press later this year or early next.  The basic thesis is that Tylor, Nietzsche, and others are right, dreaming is indeed an experiential source of religious beliefs and practices, and the best evidence from cognitive scientific research backs them up.

Rather than trying to give an all-encompassing theory of religion, I focus on a few specific areas of religious experience where dreams play an especially influential role: demonic seduction, prophetic vision, ritual healing, and contemplative practice.  The title of the book draws on psychologist C.G. Jung’s notion of “big dreams” as rare but extremely vivid dreams that make a strong and lasting impression on waking awareness.  I use resources from traditional psychology of religion (e.g., William James, Sigmund Freud) as well as from newer works in the cognitive science of religion (e.g., Emma Cohen, Harvey Whitehouse, James W. Jones) as guides in applying scientific dream research to the study of religion.

This is also the first book I’ve written using the Sleep and Dream Database (SDDb) as a primary resource.  I’m just learning how to use the digital tools of the database myself (an upgraded version of the site will come online in the next few days), and the more SDDb analyses I did for this book, the more excited I became about possibilities for future projects in data-driven dream research that look at religious and cultural phenomena with fresh, empirically curious eyes.

Tolkien’s Dreams, Past and Future

220px-Oxford_TolkienDreams play a significant role in The Lord of the Rings, J.R.R. Tolkien’s multi-part fantasy story written in the first half of the 20th century.  The dream elements become muted in Peter Jackson’s film adaptation, but in the novels they serve as an important source of insight for the characters.  According to Curt Hoffman in “Wings over Numenor: Lucid Dreaming in the Writing of J.R.R. Tolkien,” the dreams in the stories were modeled in many cases after Tolkien’s own dream experiences.  For instance, the Middle Earth legend of Numenor, a western land that was destroyed by a vast ocean wave, apparently derives from Tolkein’s personal “Atlantis Complex” and his recurrent dreams of huge, all-consuming waves.

Hoffman’s chapter appears in Lucid Dreaming: New Perspectives on Consciousness in Sleep, which Ryan Hurd and I edited for ABC-Clio.  Hoffman explains that the most remarkable story Tolkien ever wrote about dreams was also the only story he ever wrote set in the future, not in the past.  Titled “The Notion Club Papers,” Tolkien started it in 1946 but never finished the manuscript.  Hoffman says,

“The work purports to be the minutes of the fortnightly meetings of an Oxford literary society, the Notion Club (obviously a gloss for the Inklings [Tolkien’s actual literary club], although there is little one-for-one correspondence to its members), between 1980 and 1990. The manuscript’s conceit is that the papers “were found after the Summer Examinations of 2012, on the top of one of a number of sacks of waste paper in the basement of the Examinations Schools at Oxford by the present editor,” and it is represented to have been published in 2014.” (133)

Tolkien creates a strangely forward-telescoping, prospectively recursive way of framing the story—he writes about events that happen 40 years in the future, which are then discovered 20+ years after that, and are then published two years after that (at a time that happens to be our present).

In the story the club members engage in lengthy discussions of dreaming as a means of space and time travel, along with various accounts of strange adventures in thought and consciousness.  Without warning the discussion turns rather apocalyptic, as several club members describe visions that portend the coming of cataclysmic storms.  The manuscript breaks off there, and Tolkien never went back to it.  After careful study of this work, Hoffman concludes,

“It is entirely unclear what purpose Tolkien had in producing the Notion Club Papers, but his publishers were pressuring him at the time to get back to the writing of The Lord of the Rings, for obvious economic reasons, and this may explain why he did not finish the work. He never returned to it, and its status remains mysterious to this day. However, it is the clearest indication we have in all his writing of his interest in a variety of dream states and their relationship to waking physical reality. In particular, even though there is no evidence that he was aware of the writings of van Eeden on lucidity, it seems that Tolkien had a strong interest in lucid dreaming, based upon his own personal experience, and that he was attempting to put this into some kind of formulation in words that would make his experience more understandable, at least to his fellow Inklings.” (138)

Digital Dream Analysis: A New Article on Word Search Methods

170px-Asclepius_and_hygieia_reliefThe latest issue of the journal Consciousness and Cognition has an article of mine titled “Digital dream analysis: A revised method,” that’s the fruition of several years of data-driven work.  It lays out the latest developments in testing and refining the word search template programmed into the Sleep and Dream Database, a digital archive and search engine designed to promote scientific dream research.  The original article I wrote using this word search method was in a 2009 issue of Consciousness and Cognition, titled “Seeking patterns in dream content: A systematic approach to word searches.”  The new article builds on that earlier piece and extends it in two ways.

First, it presents a revised, 2.0 version of the word search template that has many improvements on the 1.0 version presented in the 2009 article.  I’m sure there will be more refinements in the future, and hopefully more researchers developing their own templates as well.  But for now, the 2.0 version is useful as a well-tested and fairly comprehensive tool for analyzing dream content simply, quickly, and reliably.

Second, the article applies the 2.0 word search template to a number of previously studied collections of dreams from very high quality sources (Calvin Hall and Robert Van de Castle, J. Allan Hobson, and G. William Domhoff).  In doing so I followed the advice of Kurt Bollacker, database engineer for the SDDb, who suggested I take “classic” studies in dream research from the past and try applying my new method to their same data.  That’s what I have done in this article: use the word search method to analyze the same sets of dreams those researchers studied, so we can see what the new method can and cannot tell us about meaningful patterns in dream content.

Here is the abstract for the article.  The whole thing, I’m told, is available for free download until November 22, 2014.

“This article demonstrates the use of a digital word search method designed to provide greater accuracy, objectivity, and speed in the study of dreams.  A revised template of 40 word search categories, built into the website of the Sleep and Dream Database (SDDb), is applied to four “classic” sets of dreams: The male and female “Norm” dreams of Hall and Van de Castle (1966), the “Engine Man” dreams discussed by Hobson (1988), and the “Barb Sanders Baseline 250” dreams examined by Domhoff (2003).  A word search analysis of these original dream reports shows that a digital approach can accurately identify many of the same distinctive patterns of content found by previous investigators using much more laborious and time-consuming methods. The results of this study emphasize the compatibility of word search technologies with traditional approaches to dream content analysis.”

Robots Dreaming

I_robot“I, Robot” (2004) is a movie about visions of the future that are haunted by dreams from the past.  Loosely based on Isaac Asimov’s classic sci-fi stories from the 1940’s, the film opens in 2035 with a harrowing nightmare that graphically repeats, PTSD-style, an accident suffered by homicide detective Del Spooner, played by Will Smith.  Several cars crashed and plunged into the Chicago River, and a robot dove into the water and rescued Spooner but not a little girl, whose chances of survival the robot deemed too low to justify trying to save.  After the agonizing experience of watching the girl sink down into the watery depths while he was lifted up to safety, Spooner becomes bitterly suspicious of all modern technologies and distrustful of claims that “intelligent” robots can improve human life.  Wearing his black leather trench coat and old-school Converse hi-tops like battle armor, Spooner is a man defiantly out of step with the march of cybernetic progress.

And then he gets a case that seems tailor made for his neo-Luddite paranoia: the first instance of a robot murdering a human.  Of course the case turns out to be much more than it first appears, and Spooner is gradually drawn into a deeper mystery about the nature of robots, humans, and the future of their relations.  At the center of the mystery is another dream—the dream of a robot.

The murder victim is Dr. Alfred Lanning (James Cromwell), a robot designer and a friend of Spooner’s.  The robot who apparently killed Dr. T. is named “Sonny” (Alan Tudyk), and Spooner finds that Sonny is far more personable than any other robot he’s ever seen, with emotions, existential questions, and a capacity to dream.

Spooner asks Sonny to describe his dreams, and the robot uses both hands to rapidly sketch an image of a large broken bridge, with a vast crowd below looking up at a single figure standing alone on a hill near the bridge.  Sonny says the single figure in the dream is going to liberate the crowd below from their oppression.  Dr. Susan Calvin (Bridget Moynahan), a colleague of Dr. Lanning who is also Spooner’s new love interest, suggests the lone figure might be Sonny himself.  Sonny considers that possibility, trusting humans to know more about the patterns of dreaming than he does.  But he also says he had the impression the liberating figure in the dream is Spooner.

Without giving away the whole plot, it can be noted that both interpretations of Sonny’s dream are true in some measure.  The climactic scenes of the movie take place near the broken bridge, so the dream has a prophetic, future-predicting quality to it.  The dream provides vital clues necessary to solve the mystery of Dr. Lanning’s death, it anticipates the character development of both Sonny and Spooner, and it heralds a revolutionary shift in robot-human interactions.  As with all “big dreams,” it has multiple levels of meaning and significance that play out across different timescales.

The ending of the film wraps up all the narrative threads, but it leaves the audience with an unsettling question.  If robots can really dream, what else might they envision about our collective future?  My guess is, it probably won’t be limited to fantasies of electric sheep.

Lucid Dreaming: New Horizons for Research

coverimage.aspxFor most of the 20th century, lucid dreaming received almost no attention from mainstream psychologists.  Most researchers seemed to think it was impossible to be dreaming and self-aware at the same time (the philosopher Norman Malcolm’s 1962 book Dreaming made exactly that argument).  Even if a few people reported having lucid dream experiences, it was easy to dismiss such claims as fantasies, exaggerations, or at best, a trivial gimmick of the mind.

Several years into the 21st century, we now know that all those assumptions about lucid dreaming were wrong.  Various degrees of consciousness in sleep are indeed possible, including the awareness that one is in a dream while it is happening.  According to demographic research, more than 50% of the general population has had at least one lucid dream experience in their lives.  Young people are especially likely to have lucid dreams, but older people have them, too.  Lucid dreams have been reported in cultures all over the world, throughout history.

In short, this is not a fringe phenomenon.  It reflects a natural capacity of the sleeping mind that is likely innate in all people.   Furthermore, this capacity can be strengthened and enhanced by several different methods, with many possible applications in waking life.  Western researchers are finally taking note.

In the newly published book Lucid Dreaming: New Perspectives on Consciousness in Sleep (Praeger, 2014), Ryan Hurd and I edited a total of 30 chapters from leading experts on lucid dreaming from all over the world.  These chapters include reflections on cutting-edge neuroscience, clinical psychotherapy, education, anthropology, artistic creativity, and religious experience.  The book shows how far we have come in understanding this powerful dimension of our dream lives—and how much more there is still to learn.
