The origins of chiropractic are surprising and rather spectacular. On 18 September 1895 Daniel Palmer, a "magnetic healer" practising in the American Midwest, manipulated the spine of Harvey Lillard, a janitor who had been partially deaf since feeling "something give in his back". The manipulation apparently cured Lillard of his deafness. Palmer's second patient suffered from heart disease, and again spinal manipulation is said to have effected a cure. Within a year or so, Palmer had opened a school, the first of many, and the term he coined, "chiropractic", was well on its way to becoming a household name.
Palmer convinced himself he had discovered something fundamental about human illness and its treatment. According to Palmer, a vital force - he called it the "Innate" - enables our body to heal itself. If our vertebrae are not perfectly aligned, the flow of the Innate is blocked and we fall ill. Chiropractors speak of these misalignments as "subluxations" (in conventional medicine, a subluxation means merely a partial dislocation). The only true cure is to realign the vertebrae by manipulating the spine, and in the logic of chiropractic it follows that all human illness must be treated with spinal manipulations. Many chiropractors also assert that we need regular "maintenance care" even when we are not ill so that subluxations can be realigned before they cause a disease.
In the words of Palmer "95 per cent of all diseases are caused by displaced vertebrae, the remainder by luxations of other joints".
All diseases are caused by 'subluxations' blocking the flow of the 'Innate' - This bit of history is important because it explains why many chiropractors treat all sorts of conditions, not just back pain. In fact, in the early days, back pain was not an issue for chiropractors at all. Today they are divided into roughly three camps. One adheres religiously to Palmer's gospel - indeed, at one stage Palmer considered establishing chiropractic as a religion. Another has moved on and now employs a range of non-drug treatments in addition to manipulations, mainly for treating back pain. The third group is situated somewhere in between these two extremes and, at least occasionally, treats many conditions other than back pain.
If you find this hard to believe, here is the evidence. A 2004 survey by the UK General Chiropractic Council revealed that most chiropractors believe they can treat asthma (57 per cent), digestive disorders (54 per cent), infant colic (63 per cent), menstrual pains (63 per cent), sport injuries (90 per cent), tension headaches (97 per cent) and migraine (91 per cent). According to a 2007 survey, 69 per cent of all UK chiropractors see themselves as more than just back specialists, and 76 per cent consider Palmer's original concepts to be "an important and integral part of chiropractic".
The answer is not clear-cut. For back pain, there is some encouraging evidence. Chiropractic manipulations have been shown in several clinical trials to be as effective as standard treatments. One needs to know, however, that standard care is not very effective for bad backs, and studies that adequately control for placebo effects tend to arrive at less positive conclusions. When my team in Exeter reviewed data from these more rigorous trials we concluded that "spinal manipulation is not associated with clinically relevant specific therapeutic effects" (Journal of Pain and Symptom Management, vol 22, p 879).
For virtually all the other conditions which chiropractors treat, where rigorous trials have been done, the evidence is weaker. In some cases, the most reliable studies have found that spinal manipulation is ineffective.
There have, however, been several hundred cases of potentially very serious complications associated with this treatment. Extreme chiropractic manipulation of the neck can damage one of the two vertebral arteries that run roughly parallel to the upper spine and supply part of the brain. The consequence of such a "vascular accident" can be a stroke, and several deaths are on record. Such disastrous events are, of course, rare; this is one reason why it is difficult to investigate this phenomenon systematically and not all studies show the same result.
In the book I co-wrote with Simon Singh, Trick or Treatment? Alternative medicine on trial, we dedicate a chapter to chiropractic. After weighing all the evidence, our conclusions were not flattering: "Warning: this treatment carries the risk of stroke and death if spinal manipulation is applied to the neck. Elsewhere on the spine, therapy is relatively safe. It has shown some evidence of benefit in the treatment of back pain, but conventional treatments are usually equally effective and much cheaper. In the treatment of all other conditions chiropractic therapy is ineffective except that it might act as a placebo."
Simon later wrote an article in The Guardian newspaper about chiropractic. In it, he quoted from the website of the British Chiropractic Association which, at the time, made fairly clear claims that chiropractors can effectively treat a whole range of childhood diseases, including asthma. The evidence for treatment of this condition is less than weak: no fewer than three controlled trials have found that chiropractic spinal manipulation has no beneficial effect. The best of these studies, published in The New England Journal of Medicine, concluded that "the addition of chiropractic spinal manipulation to usual medical care provided no benefit".
For alerting the public to all of this, and possibly preventing harm to unsuspecting children, Simon deserves much credit. Instead, he is being sued for libel by the British Chiropractic Association. I think this is a serious issue that raises two crucial questions. Is it acceptable that scientists and journalists are restricted in their criticism by the legal muscle of those who are being criticised? And is it acceptable that professional bodies, such as the British Chiropractic Association - or indeed any other organisation - are able to make therapeutic claims that are not supported by scientific data? I leave it to the reader to decide.
Profile Edzard Ernst is professor of complementary medicine at the Peninsula Medical School in Exeter, UK. In his investigations of alternative therapies, he has found only about 5 per cent are supported by scientific evidence; the rest are either ineffective or have not been tested properly.

The Discovery Institute – the Seattle-based headquarters of the intelligent design movement – has just launched a new website, Faith and Evolution, which asks, can one be a Christian and accept evolution? The answer, as far as the Discovery Institute is concerned, is a resounding: No.
The new website appears to be a response to the recent launch of the BioLogos Foundation, the brainchild of geneticist Francis Collins, former head of the Human Genome Project and rumoured Obama appointee-to-be for head of the National Institutes of Health. Along with "a team of scientists who believe in God" and some cash from the Templeton Foundation, Collins, an evangelical Christian who is also a staunch proponent of evolution, is on a crusade to convince believers that faith and science need not be at odds. He is promoting "theistic evolution" – the belief that God (the prayer-listening, proactive, personal God of Christianity) chose to create life by way of evolution.
It sounds like a nice idea, but to my mind any time you try to reconcile science and religion by rejecting Stephen Jay Gould's notion of "non-overlapping magisteria" and instead try shoehorning them into a single worldview, something suffers. My concern is that science will take the hit – and Collins's speculative arguments about divine intervention via quantum uncertainty seem dangerously poised for the punch. The Discovery Institute's concern, on the other hand, is that Christianity will take the hit. "For Christians," they write on their website, "mainstream theistic evolution raises challenges to traditional doctrines about God's providence, the Fall and the detectability of God's design in nature." For them, reconciling evolution and religious faith is simply a hopeless endeavour.
I think it's interesting that the Discovery Institute – which has long argued that intelligent design qualifies as science – seems to have given up the game and acknowledged that their concerns are religious after all. It's equally interesting that the catalyst doesn't seem to be someone like Richard Dawkins pushing atheism, but Francis Collins pushing Christianity. Perhaps the Discovery folks realise that Dawkins's followers are never going to be swayed by intelligent design; Collins, however, might very well cut into their target audience of scientifically-curious evangelicals.
The Discovery Institute has now made it crystal clear that they have no interest in reconciling science and religion – instead, they want their brand of religion toreplace science. Which makes it all the more concerning when their new website includes resources and curricula for high-school biology classes, and promotes the pseudoscientific documentary film "Expelled" as part of their campaign to introduce non-scientific alternatives to evolution under the banner of "academic freedom".
Watching the intellectual feud between the Discovery Institute and BioLogos is a bit like watching a race in which both competitors are running full speed in the opposite direction of the finish line. It's a notable contest, but I don't see how either is going to come out the winner.

In yesterday’s Guardian the famous paleontologist Simon Conway Morris (describer of many of the Burgess Shale fossils and author of Life’s Solution: Inevitable Humans in a Lonely Universe) uses Darwin Day not as a reason to celebrate what the old man did, but to point out what he did not do, and to
engage in some atheism bashingon the way:
Darwinian [sic] has reached near saturation and among the customary pieties there is little doubt that it will conveniently serve as a love-in, with much mutual self-congratulation, for atheism.
But perhaps now is the time to rejoice not in what Darwin got right, and in demonstrating the reality of evolution in the context of entirely unexceptional natural processes there is no dispute, but what his inheritance is in terms of unfinished business. Isn’t it curious how evolution is regarded by some as a total, universe-embracing explanation, although those who treat it as a religion might protest and sometimes not gently. Don’t worry, the science of evolution is certainly incomplete.
He then beats the drum for evolutionary convergence (the arrival of independent lineages as similar evolutionary solutions, like the camera eyes of vertebrates and squid).
His ultimate example of “convergence” (though it really isn’t one), is the high intelligence and mentality of humans. He claims that convergence shows the incompleteness of Darwinism.
What! Darwinism not a total explanation? Why should it be? It is after all only a mechanism, but if evolution is predictive, indeed possesses a logic, then evidently it is being governed by deeper principles. Come to think about it so are all sciences; why should Darwinism be any exception?
This is palpable nonsense. The “deeper principle” at work here is simply natural selection: organisms adapt to their environments. We can expect, in some cases, that different organisms facing similar adaptive problems will hit on similar solutions. Sharks, ichthyosaurs, and dolphins all adapted independently to life as fast-swimming predators in the ocean, and all developed similar shapes, for such a way of life requires fast, torpedo-shaped beasts with fins. And of course sometimes similar evolutionary problems are met by different solutions, and in those cases evolution is not predictable. Some fish, like seahorses, escape predators by being permanently camouflaged and hiding in a matching habitat, while others, like the flounder, can change their colors and thus be camouflaged while moving between different habitats.
Conway Morris then takes up Alfred Russel Wallace’s nineteenth-century position that the evolution of the human mind is inexplicable by evolution:
But there is more. How to explain mind? Darwin fumbled it. Could he trust his thoughts any more than those of a dog? Or worse, perhaps here was one point (along, as it happens, with the origin of life) that his apparently all-embracing theory ran into the buffers?
His solution? God of course. This is no surprise to anyone who has followed Conway Morris’s biological arguments in favor of the Christian God.
If, however, the universe is actually the product of a rational Mind and evolution is simply the search engine that in leading to sentience and consciousness allows us to discover the fundamental architecture of the universe – a point many mathematicians intuitively sense when they speak of the unreasonable effectiveness of mathematics – then things not only start to make much better sense, but they are also much more interesting. Farewell bleak nihilism; the cold assurances that all is meaningless. Of course, Darwin told us how to get there and by what mechanism, but neither why it is in the first place, nor how on earth we actually understand it.
In his peroration, Conway Morris, triumphant, asserts that the fact of human rationality and consciousness puts paid to atheism:
To reiterate: when physicists speak of not only a strange universe, but one even stranger than we can possibly imagine, they articulate a sense of unfinished business that most neo-Darwinians don’t even want to think about. Of course our brains are a product of evolution, but does anybody seriously believe consciousness itself is material? Well, yes, some argue just as much, but their explanations seem to have made no headway. We are indeed dealing with unfinished business. God’s funeral? I don’t think so. Please join me beside the coffin marked Atheism. I fear, however, there will be very few mourners.
I don’t want to fulminate at length about this terrible and misleading “logic,” but do want to make four points.
1. The conscious and rational human mind does not demonstrate convergence, because it is a singleton: it evolved only once–in the lineage leading to modern Homo sapiens. By definition, evolutionary convergence involves at least two species. I am puzzled why Conway Morris continues to use this example (well, not really puzzled–he wants to show that the evolution of the human mind is inevitable). I have criticized this viewpoint in a recent article.
2. Contra Conway Morris, there are many people who feel that consciousness is “material” in the sense that it arises from purely material causes in a material object: the brain. Understanding how and why consciousness evolved are hard problems, but to throw one’s hands up in despair and say, “God made it” is a ludicrous solution. Give biologists another century of work on the brain, for goodness sake!
3. This brings us to my conclusion that Conway Morris advocates a form of intelligent design. He seems to believe that things might have evolved as Darwin proposes–except for one thing. That, of course, is the human mind. Here a Creator must have intervened! In this piece he seems to go beyond his previously-published view that the evolution of our higher intelligence was simply inevitable; here he comes close to saying that it was impossible. It’s a bit confusing since he also makes the statement that mind was the result of an evolutionary search engine, but even if he is advocating only that God directed evolution to produce rational minds that could discover God (a rather circuitious way to create us!), that is still a form of intelligent design. Conway Morris has thus joined the ranks of what Dan Dennett calls “mind creationists,” a view that Dennett dismantled in his book Darwin’s Dangerous Idea.
4. Conway Morris is way, way peeved at atheists. He mentions them several times in his piece. He thinks he has vanquished them with his “unanswerable” evolutionary arguments. But he has not. He is simply proposing a “God of the gaps” argument, and here the gap is our mind. It’s Alfred Russel Wallace recycled. He is wrong: neither will atheism die, or even flinch a bit, and we will, I predict some day understand, as Darwin believed, that the human mind is simply a product of the blind and materialistic product of natural selection.
Conway Morris is straying from the scientific path here, but he simply can’t help himself. He is a committed Christian, and has to find some way to show that the evolution of humans was inevitable.
Postscript: Over at Pharyngula, P.Z. Myers has done a far better critique and deconstruction of Conway Morris’s lucubrations. This paragraph analyzing C-M’s prose is sheer genius:
“I cannot bear it any more. I have to make a secondary complaint about Conway Morris’s piece. He seems to regard the English language as an axe murderer would a corpse: as an awkward obect that must be hacked into fragments, and the ragged chunks tossed into a rusty oil drum he calls an article. Continuity and flow are something that can be added after the fact, by pouring in a bag of quicklime. Unfortunately, one difference between the two is that Conway Morris will subsequently proudly display his handiwork in a newspaper, while the axe murderer at least has the decency to cart the grisly carnage off to the local landfill for anonymous and clandestine disposal. One can only hope that someday the paleontologist will perfect his emulation and take his work to the same conclusion”

Intelligence is about creativity and wit, not scoring well in tests – as Einstein, a poor student but a brilliant thinker, shows
It is a common presumption that if people know a lot, they must be intelligent. Anyone who can reel off capital cities or count to 10 in several languages – or, in the case of a two-year-old girl heralded in newspapers this week, tell an apple from a banana early enough – is counted a bright spark.
And often enough intelligence, a good memory and a well-informed mind go together because intelligence prompts curiosity, curiosity results in knowledge, and memory keeps the knowledge available.
But there is no automatic connection between knowledge and intelligence. There are plenty of very bright people who do not know the world's capitals and cannot count in other languages, because they have never had a chance to learn them. In rural Africa there must be millions of smart kids who know nothing but local lore; they are Thomas Grey's "village Hampdens" and "mute inglorious Miltons".
By the same token plenty of people know lots of facts without being creative, thoughtful, quick-witted, humorous and perceptive – the marks of true intelligence. Sometimes an overload of facts is the mark of a dull and pedestrian mind, the antithesis of intelligence.
Moreover, there are different kinds of intelligence, better described as different gifts of mind, so that a person can be wonderfully talented in one respect and hopeless in another. It is misleading to describe anyone as intelligent without specifying what form the intelligence takes. Some mental aptitudes are hard-wired: gifts for maths and music (which often go together) require no knowledge, and manifest themselves early in life. So does artistic ability. Many autists have extremely high-order talents in these respects without acquiring any knowledge, or even interacting much with other people.
But other aptitudes require training, data, experience and practice. Here intelligence and a body of knowledge meet, and the former acts on the latter in productive ways. One can train a parrot to reel off English kings and queens, but it takes an accomplished historian to tell us insightful things about them.
"Intelligence tests" have always been a matter of controversy. Practice improves scores, which raises a question mark over whether they capture anything objective. If someone scores high on verbal tests and low on spatial ones, what does that overall score tell us about the individual in question? Nothing very informative.
There are many "high IQ" societies, the best-known being Mensa, which admits people with IQs in the top 2% of the population.
At Mensa's 50th anniversary in 1996 one of the founders, Lancelot Ware, said he regretted the fact that members devoted far more time to puzzles than improving the world.
That prompts a thought: intelligence is a matter of output, not scores in a test. Einstein was unsuccessful at school and no great shakes as a mathematician, but he was creative and insightful, and saw a whole new way of thinking about gravity and the structure of space-time. A vivid interest in things, and an active desire to understand more about them, is a major characteristic of intelligence. When this leads to great creativity and important discoveries, we call it genius.
In the ancient world a genius was a creature who whispered ideas, ambitions and insights into your ear. The Romantics internalised genius, identifying it with their own inner selves – what Proust called le moi profond, the deepest me. As there are many kinds of achievement, so there are many kinds of genius suited to them. To all, the wonderful old cliche about 99% perspiration applies.
IQ tests rarely predict achievement or correlate with knowledge, and they are too blunt an instrument to capture the variety of human gifts. The latter are what matter. As with everything else, we know these gifts by their fruits, not by artificial ways of defining them.

Supersense has just been published in the UK ... Like Konrad, I've only skimmed it so far - but here's some first impressions.
The book's billed as a kind of antidote to the uber-rationalists. What the author, Bruce Hood (Professor of Psychology at the University of Bristol) does is take a wide-ranging look at the quirky psychology that underpins superstitious beliefs.
You can get the gist of what he covers in his article published by The Guardian on the weekend. The common theme throughout the book is how we just can't help attributing mystical qualities to objects, people and places.

If it came to it, like the suffragettes before me, I would fight – even die – for my freedom
I am so lucky! I am a woman and I have not suffered the oppression and unfair discrimination that most women have endured throughout history, and many still do today, because I was brought up in Britain in the 20th century. I was educated at least as well as my brother, I went to one of the best universities in the world, I married the man I loved and got divorced when he and I wanted to, I brought up my children without religious indoctrination. I have been able to go where I want, pay my own way, and walk freely in the streets wearing whatever I like. I've had financial independence and an exciting and worthwhile career.
I have had all these things because other women long ago fought and even died for women's rights. Most of the suffragettes did not die, although many were repeatedly injured. Most did not have to harm, let alone kill anyone, but they certainly needed courage and many suffered abuse, discrimination, ostracism and rejection from family and friends. And some did die.
Would I be prepared to do the same? When I ask myself whether there is anything I would die for I wonder about this.
In Britain today religious oppression of women is creeping back. Children, who have no choice, are sent to faith schools where they are taught to believe ridiculous untruths, convinced that they will be sent into eternal agony after death if they disobey certain rules, and those rules can include the oppression of women by men.
In a sharia court a wife may be beaten and abused by her husband but refused a divorce; she may have to be completely covered up when she goes out so no one can see her bruises, a mother may have her children taken away from her and everyone around her accepts it; school girls are coerced to wear the veil and can neither learn to swim, enjoy team sports nor act in school plays.
What should those of us women who are free of all this do - stand by and say it's nothing to do with us? We can sign up to the One Law For All Campaign, or the humanists' campaign against faith schools, we can go on marches against sharia law. We can stand up to the popular mentality that suggests we are being racist or culturally insensitive when we demand that all women – Muslims, Christians and atheists alike, should be free of religious oppression, veils, and other symbols of subjection.
And then what? How far would I go if, by some horrendous turn of fate, my country was swept by religious fundamentalism and women's freedoms taken away? Would I be prepared to be injured? Would I be prepared to fight? Would I be prepared to die?
I don't want to fight, I don't want to injure anyone else or be injured, and I don't want to die. Yet I hope that, if this awful prospect really came to pass, my answer would be yes.
