Micheal Shermer on: "The After Life"

We were in the pharmacy waiting for perscriptions, it was rather caotic, Lei was tired and sitting on the floor, Jaala was babbling about the stuffies she just saw, and I was scanning the shelves for Advil. Faron gave some instruction, apparently Leisha didn't catch it because she responded with "Do what to who now?"
Faron and I nearly hit the floor laughing. Leisha laughed with us and said "What, I didn't know what you said or what else to say?!"
HAHAHA!
What a sight we must have made, two roly poly's rolling with laughter in the store.




This is an exerpt from Micheal Shermer's essay in response to Deepak Chopra's claims of the existance of an After Life. It's long and it has a lot of information, but stick with it, because I'd love to hear from you on it.
If you can't read the whole article, at least scroll down to the Red lettered portion, and read to comment.

Near Death Experiences and Altered States of Consciousness
Five centuries ago demons haunted our world, with incubi and succubi tormenting their victims as they lay asleep in their beds. Two centuries ago spirits haunted our world, with ghosts and ghouls harassing their sufferers all hours of the night. Last century aliens haunted our world, with grays and greens abducting captives out of their beds and whisking them away for probing and prodding. Today people are experiencing near-death and out-of-body experiences, floating above their bodies, out of their bedrooms, and even off the planet into space.
What is going on here? Are these elusive creatures and mysterious phenomena in our world or in our minds? New evidence indicates that they are, in fact, a product of the brain. Neuroscientist Michael Persinger, in his laboratory at Laurentian University in Sudbury, Canada, for example, can induce all of these experiences in subjects by subjecting their temporal lobes to patterns of magnetic fields. I tried it and had a mild out-of-body experience.
Similarly, the September 19, 2002 issue of Nature, reported that the Swiss neuroscientist Olaf Blanke and his colleagues discovered that they could bring about out-of-body experiences (OBEs) through electrical stimulation of the right angular gyrus in the temporal lobe of a 43-year old woman suffering from severe epileptic seizures. In initial mild stimulations she reported “sinking into the bed” or “falling from a height.” More intense stimulation led her to “see myself lying in bed, from above, but I only see my legs and lower trunk.” Another stimulation induced “an instantaneous feeling of ‘lightness’ and ‘floating’ about two meters above the bed, close to the ceiling.”
In a related study reported in the 2001 book Why God Won’t Go Away, researchers Andrew Newberg and Eugene D’Aquili found that when Buddhist monks meditate and Franciscan nuns pray their brain scans indicate strikingly low activity in the posterior superior parietal lobe, a region of the brain the authors have dubbed the Orientation Association Area (OAA), whose job it is to orient the body in physical space (people with damage to this area have a difficult time negotiating their way around a house). When the OAA is booted up and running smoothly there is a sharp distinction between self and non-self. When OAA is in sleep mode — as in deep meditation and prayer — that division breaks down, leading to a blurring of the lines between reality and fantasy, between feeling in body and out of body. Perhaps this is what happens to monks who experience a sense of oneness with the universe, or with nuns who feel the presence of God, or with alien abductees floating out of their beds up to the mother ship.
Sometimes trauma can trigger such experiences. The December 2001 issue of Lancet published a Dutch study in which of 344 cardiac patients resuscitated from clinical death, 12 percent reported near-death experiences (NDEs), where they floated above their bodies and saw a light at the end of a tunnel. Some even described speaking to dead relatives.
The general explanation for all of these phenomena is that since our normal experience is of stimuli coming into the brain from the outside, when a part of the brain abnormally generates these illusions, another part of the brain interprets them as external events. Hence, the abnormal is thought to be the paranormal. In reality, it is just brain chemistry.
More specifically, NDEs and OBEs have biochemical correlates. We know, for example, that the hallucination of flying is triggered by atropine and other belladonna alkaloids, some of which are found in mandrake or jimson weed and were used by European witches and American Indian shamans. OBEs are easily induced by dissociative anesthetics such as the ketamines. DMT (dimethyl-tryptamine) causes the feeling of the world enlarging or shrinking. MDA (methylenedioxyamphetamine) stimulates the feeling of age regression where things we have long forgotten are brought back to memory. And, of course, LSD (lysergic acid diethylamide) triggers visual and auditory hallucinations and gives a feeling of oneness with the cosmos, among other effects. The fact that there are receptor sites in the brain for such artificially processed chemicals, means that there are naturally produced chemicals in the brain which, under certain conditions (the stress of trauma or an accident, for example) can induce any or all of the feelings typically described in a NDE. Thus, NDEs and OBEs are forms of wild “trips” induced by the extreme trauma of almost dying.
Psychologist and paranormal researcher Susan Blackmore has taken the hallucination hypothesis one step further by demonstrating why different people would experience similar effects, such as the tunnel. The visual cortex on the back of the brain is where information from the retina is processed. Hallucinogenic drugs and lack of oxygen to the brain (such as sometimes occurs near death) can interfere with the normal rate of firing by nerve cells in this area. When this occurs, “stripes” of neuronal activity move across the visual cortex, which is interpreted by the brain as concentric rings or spirals. These spirals may be “seen” as a tunnel. Similarly, in the OBE the experience of visualizing things from above is actually just an extension of a normal process we all do called “decentering” — picture yourself sitting on the beach or climbing a mountain and it will usually be from above looking down.
These studies are evidence that mind and brain are one. All experience is mediated by the brain. Large brain areas like the cortex coordinate imputes from smaller brain areas such as the temporal lobes, which themselves collate neural events from still smaller brain modules like the angular gyrus. This reduction continues all the way down to the single neuron level, where highly-selective neurons, sometimes described as “grandmother” neurons, fire only when subjects see someone they know. Caltech neuroscientists Christof Koch and Gabriel Kreiman, in conjunction with UCLA neurosurgeon Itzhak Fried, have even found a single neuron that fires when the subject is shown a photograph of Bill Clinton. The Monica neuron must be closely connected.
The search for the neural correlates of consciousness begin at this fundamental level, and then we ratchet up from there, as we look for emergent properties of complex systems of thought that arise from these simpler systems of neuronal connections. Of course, we are not aware of the workings of our own electrochemical systems. What we actually experience is what philosophers call qualia, or subjective states of thoughts and feelings that arise from a concatenation of neural events. But eventually even the grand mystery of consciousness will be solved by the penetrating tools of science.
This is the fate of the paranormal and the supernatural — to be subsumed into the normal and the natural. In fact, there is no paranormal or supernatural; there is only the normal and the natural … and mysteries yet to be explained.

ESP and Evidence of Mind

For over a century claims have been made for the existence of psi, or psychic phenomena. In the late 19th century, organizations like the Society for Psychical Research were founded to employ rigorous scientific methods in the study of psi, and they had many world-class scientists in support. In the 20th century, psi periodically found its way into serious academic research programs, from Joseph Rhine’s Duke University experiments in the 1920s to Daryl Bem’s Cornell University research in the 1990s.
In January 1994, for example, Bem and his late University of Edinburgh parapsychologist colleague Charles Honorton published “Does Psi Exist? Replicable Evidence for an Anomalous Process of Information Transfer” in the prestigious review journal Psychological Bulletin. Conducting a meta-analysis of 40 published experiments, the authors concluded: “the replication rates and effect sizes achieved by one particular experimental method, the ganzfeld procedure, are now sufficient to warrant bringing this body of data to the attention of the wider psychological community.” (A meta-analysis is a statistical technique that combines the results from many studies to look for an overall effect, even if the results from the individual studies were insignificant; the ganzfeld procedure places the “receiver” in a sensory isolation room with ping pong ball halves covering the eyes, headphones playing white noise over the ears, and the “sender” in another room psychically transmitting photographic or video images.)
Despite finding evidence for psi (subjects had a hit rate of 35 percent when 25 percent was expected by chance), Bem and Honorton lamented: “Most academic psychologists do not yet accept the existence of psi, anomalous processes of information or energy transfer (such as telepathy or other forms of extrasensory perception) that are currently unexplained in terms of known physical or biological mechanisms.”
Why don’t scientists accept psi? Daryl Bem has a stellar reputation as a rigorous experimentalist and he has presented us with statistically significant results. Aren’t scientists supposed to be open to changing their minds when presented with new data and evidence? The reason for skepticism is that we need both replicable data and a viable theory, both of which are missing in psi research.
Data. Both the meta-analysis and ganzfeld techniques have been challenged. Ray Hyman from the University of Oregon found inconsistencies in the experimental procedures used in different ganzfeld experiments (that were lumped together in Bem’s meta-analysis as if they used the same procedures), and that the statistical test employed (Stouffer’s Z) was inappropriate for such a diverse data set. He also found flaws in the target randomization process (the sequence the visual targets were sent to the receiver), resulting in a target selection bias: “All of the significant hitting was done on the second or later appearance of a target. If we examined the guesses against just the first occurrences of targets, the result is consistent with chance.” Richard Wiseman from the University of Hertfordshire conducted a meta-analysis of 30 more ganzfeld experiments and found no evidence for psi, concluding that psi data are non-replicable. Bem countered with 10 additional ganzfeld experiments he claims are significant, and he has additional research he plans to publish. And so it goes … with more to come in the data debate.
Theory. The deeper reason scientists remain skeptical of psi — and will even if more significant data are published — is that there is no explanatory theory for how psi works. Until psi proponents can explain how thoughts generated by neurons in the sender’s brain can pass through the skull and into the brain of the receiver, skepticism is the appropriate response. If the data shows that there is such a phenomena as psi that needs explaining (and I am not convinced that it does), then we still need a causal mechanism.

Quantum Consciousness

Deepak Chopra and others will counter that there is, in fact, a perfectly cogent theory of psi, and that is quantum consciousness, which was recently featured in the wildly popular and improbably-named film, What the #@*! Do We Know?! Artfully edited and featuring actress Marlee Matlin as a dreamy-eyed photographer trying to make sense of an apparently senseless universe, the film’s central tenet is that we create our own reality through consciousness and quantum mechanics. I met the producers of the film the weekend it opened when we were both on a Portland, Oregon television show, so I got an early screening. I never imagined that a film on consciousness and quantum mechanics would succeed, but it has grossed millions and a created cult following.
The film’s avatars are scientists with strong New Age leanings, whose jargon-laden sound bites amount to little more than what Caltech physicist and Nobel laureate Murray Gell-Mann once described as “quantum flapdoodle.” University of Oregon quantum physicist Amit Goswami, for example, says: “The material world around us is nothing but possible movements of consciousness. I am choosing moment by moment my experience. Heisenberg said atoms are not things, only tendencies.” Okay, Amit, I challenge you to leap out of a 20-story building and consciously choose the experience of passing safely through the ground’s tendencies.
The work of a Japanese researcher Masura Emoto, author of The Message of Water, is featured to show how thoughts change the structure of ice crystals — beautiful crystals form in a glass of water with the word “love” taped to it, whereas playing Elvis’s “Heartbreak Hotel” causes a crystal to split into two. Would his “Burnin’ Love” boil water?
The film’s nadir is an interview with “Ramtha,” a 35,000-year-old spirit channeled by a 58-year-old woman named J. Z. Knight. I wondered where humans spoke English with an Indian accent 35,000 years ago. Many of the films’ producers, writers, and actors are members of Ramtha’s “School of Enlightenment,” where New Age pabulum is dispensed in costly weekend retreats.
The attempt to link the weirdness of the quantum world (such as Heisenberg’s uncertainty principle, which states that the more precisely you know a particle’s position, the less precisely you know its speed, and vice versa) to mysteries of the macro world (such as consciousness) is not new. The best candidate to connect the two comes from physicist Roger Penrose and physician Stuart Hameroff, whose theory of quantum consciousness has generated much heat but little light in scientific circles.
Inside our neurons are tiny hollow microtubules that act like structural scaffolding. The conjecture (and that’s all it is) is that something inside the microtubules may initiate a wave function collapse that leads to the quantum coherence of atoms, causing neurotransmitters to be released into the synapses between neurons and thus triggering them to fire in a uniform pattern, thereby creating thought and consciousness. Since a wave function collapse can only come about when an atom is “observed” (i.e., affected in any way by something else), neuroscientist Sir John Eccles, another proponent of the idea, even suggests that “mind” may be the observer in a recursive loop from atoms to molecules to neurons to thought to consciousness to mind to atoms….
In reality, the gap between sub-atomic quantum effects and large-scale macro systems is too large to bridge. In his book The Unconscious Quantum, the University of Colorado particle physicist Victor Stenger demonstrates that for a system to be described quantum mechanically the system’s typical mass m, speed v, and distance d must be on the order of Planck’s constant h. “If mvd is much greater than h, then the system probably can be treated classically.” Stenger computes that the mass of neural transmitter molecules, and their speed across the distance of the synapse, are about three orders of magnitude too large for quantum effects to be influential. There is no micro-macro connection. Subatomic particles may be altered when they are observed, but the moon is there even if no one looks at it. So what the #$*! is going on here?
Physics envy. The history of science is littered with the failed pipedreams of ever-alluring reductionist schemes to explain the inner workings of the mind — schemes increasingly set forth in the ambitious wake of Descartes’ own famous attempt, some four centuries years ago, to reduce all mental functioning to the actions of swirling vortices of atoms, supposedly dancing their way to consciousness. Such Cartesian dreams provide a sense of certainty, but they quickly fade in the face of the complexities of biology. We should be exploring consciousness at the neural level and higher, where the arrow of causal analysis points up toward such principles as emergence and self-organization. Biology envy.

Psychic Mediumship and Talking to the Dead

Deepak Chopra recounts his experience of participating in a university study of three psychics who claimed that they could communicate with those who had already “passed over” to the other side. Even though none of the psychics were told that Deepak was present, two of them identified him by name, two of them told him that he wanted to contact his recently deceased father, and one knew his childhood nickname in Hindi. He declared it a genuine experience, even while admitting that he had his doubts, especially since “My ‘father’ knew things I knew, but nothing more.”
That is more skepticism than most people muster, especially in emotion-laden readings that promise people a connection to a lost loved one. How do psychics appear to talk to the dead? I have written about this extensively, but in short, it’s a trick that involves utilizing two techniques:
Cold Reading, where you literally “read” someone “cold,” knowing nothing about them. You ask lots of questions and make numerous statements and see what sticks. “I’m getting a P name. Who is this please?” “He’s showing me something red. What is this please?” And so on. Most statements are wrong. But as B.F. Skinner showed in his experiments on superstitious behavior, subjects only need an occasional reinforcement to be convinced there is a real pattern (slot machines need only pay off infrequently to keep people involved). In an exposé I did on psychic medium John Edward for WABC New York, for example, we counted about one statement per second in the opening minute, as he riffled through names, dates, colors, diseases, conditions, situations, relatives, keepsakes, and the like. It goes so fast that you have to stop tape and go back to catch them all. His hit rate was below 10 percent, but those handful of hits were all his subjects needed to feel that they had made contact with a loved one.
Warm Reading utilizes known principles of psychology that apply to nearly everyone. The British mentalist and magician Ian Rowland’s insightful and encyclopedic book on how to do psychic readings, The Full Facts Book of Cold Reading, provides a list of high probability guesses, including identifying such items found in most homes that are sure to convince the mark that their loved one is in the room: A box of old photographs, some in albums, most not in albums; old medicine or medical supplies out of date; toys, books, mementoes from childhood; jewelry from a deceased family member; pack of cards, maybe a card missing; electronic gadget that no longer works; notepad or message board with missing matching pen; out of date note on fridge or near the phone; books about a hobby no longer pursued; out of date calendar; drawer that is stuck or doesn’t slide properly; keys that you can’t remember what they go to; watch or clock that no longer works. Here are some common peculiarities about people that are bound to give the impression that something paranormal is at work: Scar on knee; the number 2 in the home address; childhood accident involving water; clothing never worn; photos of loved ones in wallet or purse; wore hair long as a child, then shorter haircut; one earring with a missing match, and so forth. Mediums such as James Van Praagh, Sylvia Browne, Rosemary Altea and others on whom I have conducted extensive investigations are also facile at determining the cause of death by focusing either on the chest or head areas, and then exploring whether it was a slow or sudden end. They work their way through the half dozen major causes of death in rapid-fire manner. “He’s telling me there was a pain in the chest.” If they get a positive nod, they continue. “Did he have cancer, please? Because I’m seeing a slow death here.” If they get the nod, they take credit for the hit. If the subject hesitates, they will quickly shift to heart attack. If it is the head, they go for stroke or head injury from an automobile accident or fall.
I played a psychic for a day for a television special and found it remarkably easy to convince my subjects that I was really talking to the dead. Of course, anyone can talk to the dead. The hard part is getting the dead to talk back. Psychic mediums use trickery to give the illusion that the dead are communicating with us, and because people who come to mediums for help are emotionally fragile, they are also vulnerable to such effectual methods.


Prayer and Healing Studies

In April, 2006, The American Heart Journal published the most comprehensive study ever conducted on the effects of intercessory prayer on the health and recovery of patients. Directed by Harvard University Medical School cardiologist Herbert Benson, a long-time proponent of the salubrious effects of prayer, and partially funded by the Templeton Foundation, known for its support of research linking science and religion, the findings were eagerly awaited by members of both communities. There were a total of 1,802 patients from six U.S. hospitals that were randomly assigned to 1 of 3 groups: 604 received intercessory prayer and were told that they may or may not receive prayer; 597 did not receive intercessory prayer and were also told that they may or may not receive prayer; and 601 received intercessory prayer and were told they would receive prayer. Prayers began the night before the surgery and continued daily for two weeks after. The prayers were allowed to pray in the manner of their choice, but they were instructed to ask “for a successful surgery with a quick, healthy recovery and no complications.”
The results were unequivocal: there were no statistically significant differences between any of the groups. Prayer did not work. Worse, there were slight elevated complications (although not statistically significant) for the patients in the group who knew that they were being prayed for — a “nocebo” effect. Case closed.
As for previous studies in which the positive effects of prayer were claimed, there were numerous methodological problems with all of them, including:
Lack of Controls. Many of these studies failed to control for such intervening variables as age, sex, education, ethnicity, socioeconomic status, marital standing, degree of religiosity, and the fact that most religions have sanctions against such insalubrious behaviors as sexual promiscuity, alcohol and drug abuse, and smoking. When such variables are controlled for, the formerly significant results disappear. One study on recovery from hip surgery in elderly women failed to control for age; another study on church attendance and illness recovery did not consider that people in poorer health are less likely to attend church; a related study failed to control for levels of exercise.
Outcome differences. In one of the most highly publicized studies of cardiac patients prayed for by born-again Christians, 29 outcome variables were measured but on only six did the prayed-for group show improvement. In related studies, different outcome measures were significant. To be meaningful, the same measures need to be significant across studies, because if enough outcomes are measured some will show significant correlations by chance.
File-drawer problem. In several studies on the relationship between religiosity and mortality (religious people allegedly live longer), a number of religious variables were used, but only those with significant correlations were reported. Meanwhile, other studies using the same religiosity variables found different correlations and, of course, only reported those. The rest were filed away in the drawer of non-significant findings. When all variables are factored in together, religiosity and mortality show no relationship.

Operational definitions.

When experimenting on the effects of prayer, what, precisely, is being studied? For example, what type of prayer is being employed? (Are Christian, Jewish, Muslim, Buddhist, Wiccan, and Shaman prayers equal?) Who or what is being prayed to? (Are God, Jesus, and a universal life force equivalent?) What is the length and frequency of the prayer? (Are two 10-minute prayers equal to one 20-minute prayer?) How many people are praying and does their status in the religion matter? (Is one priestly prayer identical to ten parishioner prayers?) Most prayer studies either lack such operational definitions, or there is no consistency across studies in such definitions.

Theological Difficulties.

If God is omniscient and omnipotent, He should not need to be reminded or inveigled that someone needs healing. And what about all those patients who were prayed for and died? Scientific prayer makes God a celestial lab rat, leading to bad science and worse religion.
Information Fields, Morphic Resonance, and the Universal Life Force
Have you ever noticed how much easier it is to do a newspaper crossword puzzle later in the day? Me neither. But according to Rupert Sheldrake it is because the collective wisdom of the morning successes resonates throughout the cultural morphic field. In Sheldrake’s theory of “morphic resonance,” similar forms (morphs, or “fields of information”) reverberate and exchange information within a universal life force. “As time goes on, each type of organism forms a special kind of cumulative collective memory,” Sheldrake writes in his 1981 book A New Science of Life. “The regularities of nature are therefore habitual. Things are as they are because they were as they were.”
Morphic resonance, says Sheldrake, is “the idea of mysterious telepathy-type interconnections between organisms and of collective memories within species,” and explains phantom limbs, homing pigeons, how dogs know when their owners are coming home, and such psychic phenomena as how people know when someone is staring at them. “Vision may involve a two-way process, an inward movement of light and an outward projection of mental images,” Sheldrake explains. Thousands of trials conducted by anyone who downloaded the experimental protocol from Sheldrake’s Web page “have given positive, repeatable, and highly significant results, implying that there is indeed a widespread sensitivity to being stared at from behind.”
Let’s examine this claim more closely. First, science is not normally conducted by strangers who happen upon a Web page protocol, so we have no way of knowing if these amateurs controlled for intervening variables and experimenter biases. Second, psychologists dismiss anecdotal accounts of this sense to a reverse self-fulfilling effect: a person suspects being stared at and turns to check; such head movement catches the eyes of would-be starers, who then turn to look at the staree, who thereby confirms the feeling of being stared at. Third, in 2000 John Colwell from Middlesex University, London, conducted a formal test utilizing Sheldrake’s suggested experimental protocol, with 12 volunteers who participated in 12 sequences of 20 stare or no-stare trials each, with accuracy feedback provided for the final nine sessions. Results: subjects were able to detect being stared at only when accuracy feedback was provided, which Colwell attributed to the subjects learning what was, in fact, a nonrandom presentation of the experimental trials. When the University of Hertfordshire psychologist Richard Wiseman also attempted to replicate Sheldrake’s research, he found that subjects detected stares at rates no better than chance. Fourth, there is an experimenter bias problem. Institute of Noetic Sciences’ researcher Marilyn Schlitz (a believer in psi) collaborated with Wiseman (a skeptic of psi) in replicating Sheldrake’s research, and discovered that when they did the staring Schlitz found statistically significant results, whereas Wiseman found chance results.
Sheldrake responds that skeptics dampen the morphic field’s subtle power, whereas believers enhance it. Of Wiseman, Sheldrake remarked: “Perhaps his negative expectations consciously or unconsciously influenced the way he looked at the subjects.”
Perhaps, but how can we tell the difference between negative-psi and non-psi? As it is said, the invisible and the nonexistent look the same.

Middle Land
So where does this leave us? I am, by temperament, a sanguine person, so I really hate to douse the flame of that doubtful future date with the cold water of skepticism in this present state. But I care what is actually true even more than what I hope is true, and these are the facts as I understand them to be.
I want to believe Messrs. Chopra, Bem, Goswami, Sheldrake, and the others. Really I do. I gave up on religion in graduate school, but I often catch myself slipping back into my former evangelical fervor now directed toward the wonders of science and nature. But this is precisely why I am skeptical. What they offer is too much like religion: it promises everything, delivers nothing (but hope), and is almost entirely based on faith, the very antithesis of science.
I am especially skeptical whenever people argue that the Next Big Thing will save us, in our lifetime, and fulfills our deepest emotional needs. Evangelicals never claim that the Second Coming is going to happen in the next generation (or that they will be “left behind” while others are saved). Likewise, secular doomsayers typically predict the demise of civilization within their allotted time (and, of course, that they will be part of the small surviving enclave). In parallel, prognosticators of both religious and secular utopias always include themselves as members of the chosen few, and paradise is always within reach.
Where is paradise? It is here. It is now. It is within us and without us. It is in our thoughts and in our actions. It is in our lives and in our loves. It is in our families and in our friends. It is in our communities and in our world. It is in the courage of our convictions and in the character of our souls.
Hope springs eternal, even if life is not.
