How do skeptics account for the placebo effect?

This is what I see from folks like Open Mind, et. al... a complete misunderstanding of what a placebo is and why it works at all.

Yet you provide no evidence, make no specific comment upon my words other than to compare with something to do with Mr Ed, Dumbo and Star Trek? :) Are you sure you know exactly what the placebo effect is and exactly how it works?

Anyway, to moochie and Open-mind - the problem is, you have no understanding of what the placebo effect is, so I suggest learning a bit about how science works.

I don’t think I claimed to know how the placebo effect works other than say it is not just useless patient deception as many skeptics tend to imply , it is much more than that ….. what I posted was ......

An interesting theory concerning placebo effect is based on ‘neuropeptides’

( C. B. Pert, M. R. Ruff, R. J. Weber, and M. Herkenham, 'Neuropeptides and their receptors: A psychosomatic network/ /. Immunol., 1985, 35(2), 820s-826s.)

Neuropeptides can trigger emotion .... but of more significance to understanding the placebo effect emotion can produce neuropeptides (mind/body bi-directional process) ....... neuropeptides are involved in a whole array of different bodily functions, from hormone regulation, to protein manufacture, to cellular repair upon injury, to memory storage, to pain management.

...... neuropeptides have receptors all over the body…… the whole body therefore is psychosomatically wired to emotion to some degree?

PET Scans have showed placebo triggered neuropeptides in the brain. (Science 2002, 295, 1737-1740)

All perfectly valid - and none of which supports the idea that we should be supporting quack medicine on account of 'the placebo effect'.

The placebo effect is not the desired treatment of choice; it is the psychosomatic response to perceived treatment, which can help in mostly insignificant ways with minor ailments (especially psychosomatic ones), but which is not, itself, good enough cause to pursue research on homeopathy, touch therapy, or any of the other quack treatments out there.


I never said I know exactly how it works... but it's clear you support quack medicine, to some degree. "Hmm .... .... who knows yet ...... perhaps old snake oil doesn’t work anymore because we no longer believe it can possibly work anymore?"

IN other words, you would choose to use the placebo effect to deceive people in the hopes that snake oil would still 'work' - when, in fact, it never worked at all?

We've seen the nature of your posts, OM - you skirt right along the edge of valid science, but then try to misuse it to support quack notions like psi and alt-med. Wasn't it your thread (correct me if I'm mistaken) that suggested that skeptics can never conduct valid psi research, because of their own disbelief in psi?

What you've stated - amid many smilies - is that the placebo effect is some sort of faith healing; that if people will just believe, then the placebo will work miracles. And that's just not what the placebo effect is all about. Tell me - honestly - can a placebo cure AIDS, or brain cancer, or hepatitis? But this is exactly what a few homeopaths have claimed, what a few acupuncturists have claimed, etc... and this is what the public will believe, if left unchecked.

And you have definitely not demonstrated an understanding of the placebo effect, and what it is really about - only a few studies that aren't a big surprise to anyone, that show that the brain/body states we call emotions somehow have biochemical reactions associated with them. NO SURPRISE - at least to anyone who recognizes that the entirety of mental activity is, in fact, nothing more than biochemical reactions. So a 'positive mental state' is obviously going to have desirable effects on healing - and a negative mental state will have negative effects on healing. I'm betting that if someone were to do a study and REVERSE the placebo procedure - TELL all the patients they were getting a placebo, but actually medicate half of them - that you'd see effectiveness of both groups drop dramatically, but the actual medicated side would not drop as much - but they'd sue your tuchus off, I guarantee it...

The point is - the 'placebo effect' is not a suitable explanation to cover for the quackery and nonsense peddled by the alt-med industry. The 'placebo effect' is not a cure-all magical practice that can be applied to make colored crystals take care of your arthritis or magnetic boots cure your weight problems. It's just a normalizing factor in research, and a way of dealing with hypochondriac patients in general. However it works - and it does work, to some degree - it doesn't work on specific complaints and specific ailments the way some people implies that it does. It doesn't induce miracle cures in religious patients, or amazing recoveries in the faithful, or anything like that. It's a small, mostly insignificant effect, for the most part; useful in helping patients heal (when they would have anyway on their own), but not particularly useful in treating ailments, injuries, diseases - especially genetic diseases - etc.

Really, the OP was kind of dumb to ask in the first place. The question itself is covered fairly well in the research you quoted - that there is a small biochemical effect associated with positive mental states - but what was being implied (I believe) is that the 'placebo effect' was a miracle cure (or the reason miracle cures REALLY WORK) of some sort. As such, the question was pretty silly.

"How do skeptics account for the hundreds of anecdotes that show that Penta water makes people feel better?" Same type of question - it's a false claim carefully wrapped in celophane, designed to look legitimate.

Dull.

At what point does an improvement become ‘insignificant’? For example even if we assume it is only making patients feel less depressed, does that truly make it ‘insignificant’?

75% of the effectiveness of antidepressants is replicated by a placebo, that still sounds large but is only about 2 points on the HAM-D scale. If these drugs truly have a powerful antidepressant effect, then it is being largely masked by a placebo effect.
Yes the drugs consistantly beat the placebo effect, however one study, researchers analyzed 345 antidepressant trials for depression with 36,000 men and women. The goal was to determine if a link existed between the use of SSRIs and suicide attempts. Out of a 140 suicide attempts, the suicide rate was twice as high in patients taking SSRIs, when compared to those taking placebo pills.

with minor ailments (especially psychosomatic ones), but which is not, itself, good enough cause to pursue research on homeopathy, touch therapy, or any of the other quack treatments out there.
So would you recommend people just needing reassurance and reduced depression take an antidepressant instead, with a list of possible side effects never mentioned to those tested in original trials (that might reduce effectiveness in actual prescribed trials?) I supposed you could give them an unethical placebo but if it says placebo on the bottle it is no longer a placebo.

With regard to ‘touch therapy’ how do you know it has no beneficial effect? …..in 1995 rat pups deprived touch were found to have dramatic reduction in growth hormone http://www.nature.com/npp/journal/v28/n6/full/1300125a.html

Earlier studies on human emotional deprivation suggest similar too (e.g. G.Powell studies in 1967 and 1973) .

Easy to test, give people a placebo but tell them it is a inactive placebo, if the effect is less in comparison to another placebo told to be a wonderfully powerful new drug …. This would suggest my statement in principle is correct.

IN other words, you would choose to use the placebo effect to deceive people in the hopes that snake oil would still 'work' - when, in fact, it never worked at all?
How do you know it never worked at all, perhaps snake oil cannot work because skeptics have told people it cannot work ;)
I should really look into researching whether famous past drugs that got abandoned lost effectiveness over time with doubt or were always rather ineffective.

We've seen the nature of your posts, OM - you skirt right along the edge of valid science, but then try to misuse it to support quack notions like psi and alt-med.
Have you considered the possibility that the information you are reading on organized skeptic websites is somewhat biased? Being skeptical is fine but that should include being skeptical of organized skepticism! :) The skeptic paradigm has moved from ‘doubt’ to a defense of the conventional and predictable science against anything that falls outside the conventional that is hard to predict or understand …. And a placebo was conventionally supposed to be completely useless and inactive patient deception, rather than admit a placebo can have a beneficial effect. It seems skeptics, in a desire to shoot down anything alternative, prefer to dismiss weak effects altogether. It is always 'nothing but something else' ... yet this 'something else'
skeptic claim often lacks the necessity of 'the burden of proof is upon the claimant' ........ To cast doubt upon a claim is OK but to debunk with unproven explanation is dishonorable IMHO.

What you've stated - amid many smilies

- is that the placebo effect is some sort of faith healing; that if people will just believe, then the placebo will work miracles. And that's just not what the placebo effect is all about. Tell me - honestly - can a placebo cure AIDS

People do occassionally recover from cancer after conventional medicine as said it can do no more, of course a skeptic will offer another (unproven) explanation as to what really occured..... but are you claiming emotion and belief can never have an effect upon cancer?

or hepatitis?

I’m feeling too lazy too look :) But I know there are at least 3 trials showing a possible link between emotions, stress and immunity.

Perhaps skeptics just believe emotions can make us ill but never better?…. Just a one directional process? Several earlier posters in this topic said a placebo cannot cure to belittle the effect …. yet seldom does a drug actually cure, it is often an effective maintenance dose to counteract and slow down deterioration? Can emotions also slow down deterioration too, if stress impairs immunity?

But this is exactly what a few homeopaths have claimed, what a few acupuncturists have claimed, etc... and this is what the public will believe, if left unchecked.
I am not against skeptics challenging anything, I am against them belittling or entering denial of weak effects

And you have definitely not demonstrated an understanding of the placebo effect
I don't think anyone knows enough about the placebo effect, that most certainly includes me too.

and what it is really about - only a few studies that aren't a big surprise to anyone, that show that the brain/body states we call emotions somehow have biochemical reactions associated with them. NO SURPRISE - at least to anyone who recognizes that the entirety of mental activity is, in fact, nothing more than biochemical reactions. So a 'positive mental state' is obviously going to have desirable effects on healing - and a negative mental state will have negative effects on healing.

Well I agree ...... so would you are just advising people to think negatively over alternative treatments and positively over conventional ones? :) I do think many people try alternative therapies because the conventional one wasn’t satisfactory. ‘Sorry Mrs X, there is nothing more we can do for your cancer …… but don’t try anything else!’

I'm betting that if someone were to do a study and REVERSE the placebo procedure - TELL all the patients they were getting a placebo, but actually medicate half of them - that you'd see effectiveness of both groups drop dramatically, but the actual medicated side would not drop as much - but they'd sue your tuchus off, I guarantee it...

Well I wouldn't 'guarantee it' but I would expect the same and I would like too see more of these trials done.

The point is - the 'placebo effect' is not a suitable explanation to cover for the quackery and nonsense peddled by the alt-med industry. The 'placebo effect' is not a cure-all magical practice that can be applied to make colored crystals take care of your arthritis or magnetic boots cure your weight problems. It's just a normalizing factor in research, and a way of dealing with hypochondriac patients in general. However it works - and it does work, to some degree - it doesn't work on specific complaints and specific ailments the way some people implies that it does.

I agree that many alternative practitioners are possibly giving the wrong reason for the benefit.

It doesn't induce miracle cures in religious patients, or amazing recoveries in the faithful, or anything like that.
Actually to a lesser degree I see a general lack of miracle cures in conventional medicine too. Surgery has been a great success. Slowing health deterioration with drugs has been comparatively successful (not necessarily clearly proven better in long term over diet and exercise) but no doubt vital if serious acute conditions.

As to whether miracles cures exist, that is a paranormal debate. I’m not religious, I have no religious faith … but I think belief produces significant if generally weak effects in health (placebo) and also possibly in the paranormal. (claimed sheep and goat effects)

It's a small, mostly insignificant effect, for the most part; useful in helping patients heal (when they would have anyway on their own),
I would dispute that, if stress can worsen a disease or cause it … how can you be so sure they would have healed without the placebo like effect?

but not particularly useful in treating ailments, injuries, diseases - especially genetic diseases - etc.
Again conventional medicine isn’t that successful on genetic disease either.

I’m still not sure it is that clear cut, our physical height is determined by our genes but our environment modifies the expression of those genes. (e.g. rat pup study mentioned above).
 
Open Mind said:

When that improvement is considerably less than improvement with conventional medical means, it is an 'insignificant improvement'.

75% of the effectiveness of antidepressants is replicated by a placebo, that still sounds large but is only about 2 points on the HAM-D scale. If these drugs truly have a powerful antidepressant effect, then it is being largely masked by a placebo effect.

I won't disagree on antidepressants, for two main reasons: 1) I personally doubt the effectiveness of the diagnosis and treatment of some patients, considering many don't need the drugs at all and some are actually harmed by the drugs. I've seen that myself. - and 2) I'm not knowledgable on the broad scope of psychological drug therapy, except to notice that some scientists consider many of those drugs nearly as quack-oriented as some of the alt-med treatments.

Yes the drugs consistantly beat the placebo effect, however one study, researchers analyzed 345 antidepressant trials for depression with 36,000 men and women. The goal was to determine if a link existed between the use of SSRIs and suicide attempts.

See above. I don't doubt that one bit.

So would you recommend people just needing reassurance and reduced depression take an antidepressant instead, with a list of possible side effects never mentioned to those tested in original trials (that might reduce effectiveness in actual prescribed trials?) I supposed you could give them an unethical placebo but if it says placebo on the bottle it is no longer a placebo.

Of course not. See above.

I mispoke. There is a beneficial effect, with regards to growth and development, and emotional well-being; but people are getting 'touch therapy' for ailments that have nothing to do with these areas of medicine. It's fairly well known, I thought, that infant and toddler development is enhanced - even dependent upon - caring physical contact.

Easy to test, give people a placebo but tell them it is a inactive placebo, if the effect is less in comparison to another placebo told to be a wonderfully powerful new drug …. This would suggest my statement in principle is correct.

No, this would be comparing a nocebo to a placebo. The placebo - the pills claimed to be a new wonder drug - would have an improved effect, there can be no doubt. But the effect has nothing to do with the pills, rather than the presentation.

How do you know it never worked at all, perhaps snake oil cannot work because skeptics have told people it cannot work ;)

By 'skeptics' I presume you actually mean 'valid scientific research'? ;)

I should really look into researching whether famous past drugs that got abandoned lost effectiveness over time with doubt or were always rather ineffective.

That would be difficult, since famous past drugs generally had numerous anecdotal reports and very little valid scientific data to read through; in other words, by looking at case studies, these drugs should most often be demonstrably effective, up to the point someone realizes they don't work at all. Bias, and all that, you know.

Have you considered the possibility that the information you are reading on organized skeptic websites is somewhat biased? Being skeptical is fine but that should include being skeptical of organized skepticism!

Since this is the only 'organized skeptic website' I've ever been to, and since I base my information on real science and actual studies, then, no, I don't consider the information here to be an y more biased than on any other public web forum. Skepticism is a technique of basing judgements upon valid evidence; therefore, skeptical claimes are less biased than other claims.

The skeptic paradigm has moved from ‘doubt’ to a defense of the conventional and predictable science against anything that falls outside the conventional that is hard to predict or understand …

Total strawman - and completely wrong.

And a placebo was conventionally supposed to be completely useless and inactive patient deception, rather than admit a placebo can have a beneficial effect.

Also wrong. Placebos are conventionally supposed to be a psychological means of dealing with patients whose symptoms cannot be treated through available medicine, where those symptoms are not life-threatening or crippling. In science, placebos are conventially a means of removing one more variable - the psychosomatic variable - from drug testing.

It seems skeptics, in a desire to shoot down anything alternative, prefer to dismiss weak effects altogether.

No, skeptics, in a desire to shoot down quackery and fraud, prefer to dismiss lame theories about how some alt-med ]i]might[/i] work in favor of valid scientific research.

Can conventional medicine cure AIDS? Are you claiming belief and emotion has no effect upon AIDS?

Putting more words in my mouth. I never said conventional medicine can cure AIDS - but some alt-med practicioners are claiming they can, wrongly. Conventional medicine isn't claiming a cure, now, is it?

People do occassionally recover from cancer after conventional medicine as said it can do no more, of course a skeptic will offer another (unproven) explanation as to what really occured..... but are you claiming emotion and belief can never have an effect upon cancer?

Did I make that claim? I seem to have missed it. But some alt-meds are claiming total cure of cancer - are you claiming that alt-meds that play on one's emotions and beliefs are valid and consistent cures for cancer?

I’m feeling too lazy too look :) But I know there are at least 3 trials showing a possible link between emotions, stress and immunity.

Never said otherwise - but a placebo is not a 'cure'. It can have an effect, but not a preferential effect to treatment, and not a consistant and reliable effect.

Perhaps skeptics just believe emotions can make us ill but never better?…. Just a one directional process? Several earlier posters in this topic said a placebo cannot cure to belittle the effect …. yet seldom does a drug actually cure, it is often an effective maintenance dose to counteract and slow down deterioration? Can emotions also slow down deterioration too, if stress impairs immunity?

Hey, it's your strawman - burn it however you like.

I am not against skeptics challenging anything, I am against them belittling or entering denial of weak effects

And I'm not against weak effects. I am against people taking hard-earned money from gullible sick people on the slim chance that a placebo effect might help them.

I don't think anyone knows enough about the placebo effect, that most certainly includes me too.

A lot of people know a heck of a lot more about it than you or I do.

Well I agree ...... so would you are just advising people to think negatively over alternative treatments and positively over conventional ones? :) I do think many people try alternative therapies because the conventional one wasn’t satisfactory. ‘Sorry Mrs X, there is nothing more we can do for your cancer …… but don’t try anything else!’

Alternative treatments are fine - if they have valid mechanisms of effect. If they're just sugar pills or colored lights, I would tell people to reconsider these quack treatments, end of story. "Sorry Mrs. X, there is nothing more we can do for your cancer. If it makes you feel better, you might seek some form of faith healing. There is no valid mechanism of effect for most of them, but in rare cases, cancer such as yours might go into remission if you keep a positive outlook and stay away from harmful alt-med treatments." At least that's honest.

I agree that many alternative practitioners are possibly giving the wrong reason for the benefit.

As well as vastly over-estimating the benefit.

Actually to a lesser degree I see a general lack of miracle cures in conventional medicine too. Surgery has been a great success. Slowing health deterioration with drugs has been comparatively successful (not necessarily clearly proven better in long term over diet and exercise) but no doubt vital if serious acute conditions.

At least science isn't claiming 'miracle cures'. Too many alt-med practicioners are.

As to whether miracles cures exist, that is a paranormal debate. I’m not religious, I have no religious faith … but I think belief produces significant if generally weak effects in health (placebo) and also possibly in the paranormal. (claimed sheep and goat effects)

Your beliefs are obvious in this regards.

I would dispute that, if stress can worsen a disease or cause it … how can you be so sure they would have healed without the placebo like effect?

Because some people do. In the case of mild illnesses - for example, the common cold - it is guaranteed they will heal with or without the placebo effect.

Again conventional medicine isn’t that successful on genetic disease either.

More successful than homeopathy, touch medicine, or faith healing is.

I’m still not sure it is that clear cut, our physical height is determined by our genes but our environment modifies the expression of those genes. (e.g. rat pup study mentioned above).

I have no idea what you're trying to say there. Of coure environment plus genes equals whatever we are. What does that have to do with what we are discussing?

Consider, for a moment, someone who comes down with a case of lice. (This, BTW, is a true story - an anecdote, and therefore without value, but true nonetheless)

The person in question, being leery of toxins on his head or chemicals in his body, seeks the advice of his local holistic practicioner; the doctor rightly advises commercial products, a variety of treatments for the home, and of course, shaving the hair off. "Nah," the person says, "isn't there something else?"

So the alt-med doctor prescribes for him a homeopathic shampoo, whose label claims, "Guaranteed to kill lice in less than 24 hours!" The guy takes the stuff home, douses his head in it, and waits.

Three days later, he's back, asking for another alt-treatment, 'cuz that one ain't cutting it. And on and on it goes until, finally, exhausting all other treatments, the guy shaves his head (and his wife and childrens', because they're all infected now), and undergoes conventional treatment. At this point, he's spent approx. $150 on alt-med treatments, to no effect. Where's the placebo effect there? But this is exactly what happens, with many ailments, to many people. This is exactly why alt-med should be viewed with suspicion and concern.

If it's something minor, like a cold or a mild sore throat, then sure, a placebo might be just as effective a treatment. But conventional meds aren't claiming a 'cure' for a cold, and many sore throats can only be treated for pain and swelling, and nothing more. The alt-meds can do no better - and no worse. But once you start trusting alt-med to 'cure your cold', you start trusting alt-med for more vital treatments, and there are very few scrupulous holistic doctors out there willing to draw the line and let you know when a quack treatment isn't going to help you. (I happen to know one such doctor, but he's a pretty weird duck.)

Take it however you want, of course. If you want to risk your health or your life on treatments that only make you think you're feeling better, then go for it. I'll stick to treatments that have some manner of effect. Whatever treatment I'm offered - whatever meds have EVER been prescribed to me - I educate myself on the meds involved, their effect, side-effect, mechanisms of action, etc. until I'm satisfied and either take the medicine, or seek an alternative medicine, or toss it aside and let time take its course. Unfortunately, most people don't bother; they trust their healers to be honest and to have effective treatments; so they swallow the B.S. hook, line, and sinker.
 
Open Mind said:

That’s another major misconception that people have.

The placebo effect does have a psychological benefit as the person often feels subjectively better after a treatment; even if the treatment was homeopathic water or non-existent “vibrational energy” from a crystal.

Skeptics do not deny the placebo effect; merely take account of it when assessing medical treatments. If a treatment is compared to a placebo control and performs no better than the placebo control, then the treatment is useless. It just means that any benefit the patient feels is due to the placebo effect.

The placebo effect is real, that’s why treatments need to be compared to a placebo control and not compared to doing nothing.

If the placebo effect gives a perceived benefit why not allow treatments that induce it?

1) The placebo effect is a perceived benefit. It does not cure illness or disease.

2) All treatments induce the placebo effect, so is it not better to use treatments that are efficacious i.e. placebo plus a real benefit?

Finally,

This is not a “them vs us” argument.

Whether one classes oneself as a skeptic or anything else is irrelevant. We all need to understand as much as we can about the placebo effect and take it into account wherever appropriate. It is a factor, if ignored, that can lead us to wrong conclusions.

When it comes to testing, the placebo effect is a menace, and it is undoubtedly the reason why so many bogus therapies have flourished and persisted: so many people misunderstand it.

Let me get this straight... If conventional medicine cannot cure something... And something that induces a placebo effect CAN its not a valid cure?

What kind of logic is that? If something can cure someone, by whatever means, it is a valid treatment. I don't care if it takes a long time, I don't care if the effect seems insignificant. If it works, then it works. I don't care if you have to do a stupid funky chicken dance while patting your stomach twice chanting the american anthem backwards, if it causes the right effect then it works.

Why do most alternative med doctors say that each patient is different and should be treated different? Maybe they understand that it is a placebo type effect and by them working closely in convincing the patient that it works, it has the desired effect.

This is exactly like treating the mind of the patient instead of the body. What other field attempts to do this? Psychiatry. It sure is a valid accepted field of treatment in our modern society. If that is valid, so should all of these "quacky" treatments as some of you put it.
 
Let me get this straight... If conventional medicine cannot cure something... And something that induces a placebo effect CAN its not a valid cure?

No, no, no... if conventional medicine cannot cure something, neither will a placebo; placebos NEVER cure anything.

However, if a regular medicine doesn't have a desired effect in treatment, it still will have THE EXACT SAME PLACEBO EFFECT that a placebo would have.

This is another glaring example of a complete misunderstanding of how the placebo effect works... or what it is.

Please, Moon, our species is supposed to be smarter than THAT. :D
 
This reminds me of a story told to me by a colleague.

Colleague was a vet in general practice, and he had a problem case of a dog with very bad skin. The owner was a bit tight, and he didn't want a lot of expensive diagnostic tests, and the case was a nightmare. Nothing the vet tried had any significant effect on the problem.

Then the owner seemed to lose patience, and announced that he was off to consult the local homoeopath. The vet was actually quite relieved - he just wanted rid of this patient. Then, a couple of months later, the owner brought the dog back to my colleague. At first he assumed that the owner had given up on the magic sugar pills, and wanted to give real medicine another go. But no. "I just had to bring him back to see you to let you see the miracle cure that the homoeopathy has achieved!"

The only snag was, according to my colleague, the dog's skin was, if anything, actually slightly worse than it had been last time he'd seen it.

So, it seemed as if the owner's belief that the homoeopathy would help had changed his perception of the situation so that he saw a cure when in fact there was none. But why? Why did the homoeopathy have that effect, while the real medicine didn't?

It's obvious, really. The vet hadn't been confident that anything he was using was going to solve the problem. And when the dog came back no better, he acknowledged that the dog was no better and no progress was being made. On the other hand (we assume) the homoeopath showed all the confidence in the world, and even when an unbiassed observer would have said that there was no change, he claimed that the dog was in fact better. The owner's desire for that to be true, plus his confidence in the authority of the homoeopath's pronouncements, convinced him.

All placebos aren't equal. A placebo delivered in a half-hearted manner after a curt five-minute consultation, followed by a realistic appraisal of the patient's objective condition, is going to do a lot less than an hour-long visit where the patient is encouraged to talk obsessively about himself and made to feel really individual and special, followed by a rosy assurance that he's really looking so much better he's practically cured, is likely to do a great deal more.

It's just a pity the latter involves lying to the patient, which most doctors are averse to doing.

In fact some homoepaths (and I think the "large study in Germany" is in this category) have capitalised on this. They choose a mild, vague, chronic and fluctuating condition - the sort of thing that can respond really well to skilled placebo administration. Also, it has to be something that there is a licensed medicine for, but the licensed medicine has to be something which actually isn't a great deal of use. Fortunately there are quite a few things like this!

Then they set up a comparative trial with homoeopathy. But instead of doing it right, treating the homoeopathic group and the control group exactly the same as regards length of consultation and so on, and just varying whether they are given their individualised remedy or a blank sugar pill, they compare the full-blown homoeopathic "therapeutic consultation" including sugar pill, with a quick five minutes through the GP's surgery and a quick impersonal prescription for the not-much-good licensed medicine.

Hey presto, homoeopathy does just as well as licensed medicine!! Might even do better, given the right patients.

This protocol is virtually assured to give positive results for homoeopathy, and great headlines. It's dishonest as hell, but that doesn't stop them.

Some people have said that the main problem for real medicine is to find out how to get the effect of a nice cup of tea and a chat with a sympathetic listener into their case management regime, so take advantage of this effect, while not lying to the patient that sugar pills are medicine.

Sure, for minor, chronic, self-limiting things this is a fair point. But a nice cup of tea and a chat never cured a cancer yet.

No, no, no... if conventional medicine cannot cure something, neither will a placebo; placebos NEVER cure anything.

However, if a regular medicine doesn't have a desired effect in treatment, it still will have THE EXACT SAME PLACEBO EFFECT that a placebo would have.

This is another glaring example of a complete misunderstanding of how the placebo effect works... or what it is.

Please, Moon, our species is supposed to be smarter than THAT. :D

********. There have been many cases where the placebo HAS cured something conventional medicine cannot cure. I think alot of skeptics are so anal on the semantics of something being said and miss the point entirely.

Lets not call it placebo, lets call it a doohicky. A doohicky effect, no matter how rediculous, if it works, then it works.

Happy now? If our specie is so smart, then why do we have so many skeptics?
 
At last I think I now understand the skeptic explanation of a placebo!!!!! Eureka!
Placebo = nuisance effect that is completely useless but can be of benefit and improve many medical conditions :confused: ;) :rolleyes:

If a treatment is compared to a placebo control and performs no better than the placebo control, then the treatment is useless. It just means that any benefit the patient feels is due to the placebo effect.
‘then the treatment is useless’ many trials indicate even if the treatment is no better than a placebo but both may have significant beneficial effects
Here is yet another I didn’t mention earlier ….a study found 30% of patients with mild to moderate elevated blood pressure who received a placebo, had their blood pressure lowered to below the set goal of a diastolic pressure of lower than 90 mm H

If the placebo effect gives a perceived benefit why not allow treatments that induce it?
1) The placebo effect is a perceived benefit. It does not cure illness or disease.

How do you guys know, emotions can never cure disease? When people do recover you are just assuming another explanation occurred, the famous skeptic claim ‘it is nothing but something else’ which for some reason never requires any burden of proof?
Also one could say most conventional drugs do ‘not cure illness or disease’ . If you have blood pressure, how often does a doc say ‘take a course of these pills for 10 days, then you are cured and can stop the medicine’ .

A placebo is often more than a perceived benefit, the effect may well be to weak to be off much benefit to some conditions/patients but I have listed in this topic numerous examples of placebo expectation producing a improvement that is more than merely a imaginary or perceived physical benefit.

Another trial I never mentioned earlier ……. the release of dopamine is impaired in people with Parkinson's. In one study the researchers measuring dopamine levels patients did not know whether they were taking the Parkinson's drug apomorphine or a placebo. Dopamine was also measured under normal conditions when patients knew they were not taking a placebo. Yet when patients were unknowingly taking a placebo, they experienced an increase in dopamine levels similar to that caused by Parkinson's drugs.

2) All treatments induce the placebo effect, so is it not better to use treatments that are efficacious i.e. placebo plus a real benefit?

Well yes, assuming the treatments have less side effects. As mentioned earlier antidepressant drugs very slightly beat a placebo, which is still good because the placebo worked well but the antidepressant was later found to have double the risk of suicide (even if a small numbers)

And as I mentioned earlier there could be a nocebo effect of providing drugs with a list of possible sides effects when finally released absent from the original trials. With regard to negative expectation women who believed they are prone to heart disease were well over 3 times more likely to die earlier than women under similar risk to those who didn't believe "Nocebos Contribute to a Host of Ills." - R Voelker. Journal of the American Medical Association 275 no. 5 (1996): 345-47

Finally,
This is not a “them vs us” argument.
Whether one classes oneself as a skeptic or anything else is irrelevant.
I would agree, but it often seems the skeptics are in a campaign to outlaw alternative medicine (even if harmless and likely to be utilizing a placebo effect) and enforce conventional medicine ….. that due to patient rights (even to be foolish) really should be conventional medicine encouraged for everyone + ‘complimentary’ medicine for those who seek it.
When it comes to testing, the placebo effect is a menace, and it is undoubtedly the reason why so many bogus therapies have flourished and persisted: so many people misunderstand it.
It seems the bogus menace can make people at least slightly healthier, if generally short of a cure ;) In one study fake knee operations were performed and worked as well as the standard and very common surgical procedure (5000 dollars per operation- 3 billion dollars per year in the US) . After 2 years later, the real surgery and fake surgery groups had made similar gains in walking and stair climbing, and their pain had eased to comparable degree.

This does not sound like the type of placebo effect you are suggesting?
Bedside manners, the warmth of the doctor-patient relationship, and other features of good doctoring contribute to the outcome of medical care, yet they have been treated contemptuously by the biomedical community as factors that produce placebo (or context, or non-specific) effects that should not work even if they do. The most impressive examples of the potential clinical relevance of context of care have been found in relation to the survival of cancer.

A person goes to a psychiatrist to get hypnotized to stop smoking.

A person goes to a psychiatrist to talk about something affecting his stress levels thereby causing health problems.

Both of those conditions were cured by a psychiatrist, with nothing but words. Are words placebo effects. If these effects have no use what so ever, then the whole field of psychiatry is just full of quacks.

Incidentally, the average person is AFRAID of needles. You would think going to the acupuncturist who sticks a bunch of needles in you would result in a negative effect, not positive.

I think you are getting confused between psychological conditions and physical conditions.

Some psychological condition are obviously treatable by changing mental states which can be achieved by words.

Physiological conditions are unrelated to mental conditions, except for those which involve an element of psychological activation e.g. stress caused by inappropriate threat response mechanism (such as in the workplace where there is no physical threat, but the threat mechanism is still triggering).

Obviously psychologists can treat disorders that have a purely psychological basis. Because some aspects of the human body need a certain degree of direct mental control (eg when there is a threat adrenaline is released to increase heartrate, blood flow to certain areas, away from other areas etc.) then when something goes wrong with the mental control of these mechanisms it will be psychological treatment that is required.
But this does not mean that the mind has any healing power over the body.
Only that a psychological problems will respond to psychological treatment. And physical results of that psychological disorder will be alleviated by the treatment.

To imply any physical significance to words or any physical healing properties to placebo is incorrect.

Incidentally, the average person is AFRAID of needles. You would think going to the acupuncturist who sticks a bunch of needles in you would result in a negative effect, not positive.
Exposure to things we have fear of is a common method of treating phobias. It breaks the cycle of avoidance.

In fact flooding is a method of treating phobias that involves high levels of exposure to the feared stimulus:
One simple form of exposure treatment is that of flooding, where the person is immersed in the fear reflex until the fear itself fades away.

Who said that?

If a skeptic said that then they are wrong. If you read my posting above you will see a better explanation than the one you've just stated.

No I cannot provide a verified example, ask Open Mind, he had something that was close. I have read alot of anecdotal proof but of course these are simply not good enough for you skeptics.

Pragmatic fallacy talks about the truth. What does that have to do with something that works? If something works it doesn't matter if it is true or not. Yes the reason might be totally different than the one we assumed, but the net effect is the same.

How do we protect from people who are close minded who sees the elephant as a wall, a rope a trunk etc? It is ok to be doubtful of something, that is smart. But to ignore something because you are doubtful, that is not so smart. Skeptics are sometimes the stupidest people in the world because they fail to make the intellectual jump necessary to go beyond a popular but misguided belief. Skeptics doubted the world was round because everyone else said it was flat. It took many many years before that was disproven. I think I rather be protected from people who are stupid than people who think they are smart.
 
Actually, skeptics doubted the world was flat, because there was evidence that the world was round.

Skeptics doubted that the earth was the center of the universe, because there was evidence otherwise.

Skeptics doubted that diseases were caused by 'miasms', because of evidence.

The thing that divides a skeptic from a non-skeptic is simple: evidence.

Thats the old glass is half empty/half full argument. There were probably equal amount of skeptics who believe in both sides of the argument. The evidence of SOMETHING happening is there, thats why we have these different phenomenon.

A proper skeptic would find out WHAT it is truly, and not dismiss it as something that doesn't exist. I'm as skeptical about everything as the next person. I do not rule out any possibilities until I am faced with an explaination/proof that totally contradicts. That does not mean that if some other explaination/proof comes out later that disproves the early proof that I won't accept it.

You have to keep an open mind while thinking critically. To fail in either is to be an irresponsible skeptic who is no better than the fanatical believer.

How many times have we seen reports coming out saying this or that drug etc doesn't work the way it should because further tests proved the initial findings invalid? We haven't done enough tests with accupuncture to really give a verdict either way. Until there is definately proof or disproof, nobody is right.
