And what does go wrong with the general DBPC idea of giving have the patients of a homeopath a placebo and the other half what the homeopath prescribed. After a year the homeopath ranks the patients according to the improvement they recieved. The remedy ones should score far better, if there is a difference between remedy. What problems with that except ethical ones? And if you argue, that homeopath knowing half his patients do not get a remedy, is then hindered in estimating and treating all, then what about a test where even the homeopath does not know a test is running? (Clearly this would be difficult to arrange and nearly impossible to do without braking laws, but please ignore those problems for the moment) Quote:
Example for that search in the current thread at Randiland, a sceptic suggest testing the ability of arnice to help healing scratches. He does suggest this, since very often arnice is said to have that ability. I even know a kindergarten teacher, who gives small childs half a dozen arnice c200 pills, when they injure themselves painfully, assuming it helps the healing process and reduces the pain. No either this is complete nonsense from a homeopathic pov, but where are then the homeopaths arguing publically against such practice or it is mostly correct, but then a dbpc is easy and straightforward, with no excuse in case of success or failure. Another example is my thread about animal test ("New playground"), with animals several problems of test with humans can be avoided, but apparently that idea is not interesting. Any idea why? Quote:
We can also deal with different answers than "yes/no" and can count from this to that. The only thing where a "yes/no" answer is the only satisfying result is "is a sub-avagadro homeopathic remedy different from carrier substance?". Anything else but yes or no does not make sense with that question. Quote:
Though i would be interested, how she recognized, that Steve Barrett does not know enough about homeopathy. Do you know how to recognize, that someone does not know much about homeopathy? Can a disbeliever understand homeopathy? Carn |

E.g. the case study at http://www.hpathy.com/casesnew/khopa...physagria1.asp concludes that the improvement was due to 5 doses of some remedy(actually only for one is named when it was given). But i fail to see the point that disproves the possiblity, that she mainly improved due to the psychological effects of finally talking about all the stuff that worried her through the years and her husband finally getting a idea what her problems are. Hey, you know far more about that than i, read the case study and tell me, could such a improvement be intiated and enhanced solely by psychotherapy? Quote:

But with case studies you have a method of creating a new individual markstick for every new rock and never the same rock is measured twice. If your method is flawed,then you will measure each time wrong as well. But you have the further disadvantage, that even if someone has an idea, what is wrong with your method, he could never show if his idea realy changes something, because neither he can remeasure the same stone, nor can he create a yardstick for the same stone and compare it to your yardstick for that stone. A fundamental flaw could be in there without any chance to detect it. Quote:
But i got a non useful definition of the placebo and verum effect: Make 2(*) perfect copies of the universe the moment the patient has the idea to go to the doc. In one universe you do not do anything. In one universe change the treament, so that one component can have only a very, very little effect(e.g. replace remedies with water/sugar/alcohol or let the patient keep no diet or ...) upon patient, without patient or doc knowing about this(yep, for acupuncture its pretty hard to determine the placebo effect). In the third you remove the component entirely with both the patient and the doc knowing it is not there, but not knowing it is a experiment. The difference in objective and subjective health criteria between the 2 patients in the first 2 universes is the verum effect of this component, the placebo effect is the difference between the patient in the second and the third universe. ((*) Obviously if universe is non-deterministic you need to make several thousand copies for each case and statistically analyse the differences, but these differences are still verum and placebo.) Probably you already noticed, approximation of above process is DBPC. Quote:
And delusions can cross cultural borders, e.g. Ufos are now reported world wide, Astrology has long since spanned the world, acupuncture, feng shui and i don't know what asian stuff is running through europe and US(i do not know its all delusions, but certainly some is delusion). I can start a thread about that on Randiland, people will know there more examples, if you need. I guess the suprise would be more if some delusions cannot cross cultural borders, the only difference i expect to be the speed. And the point about superior bedside manner is actually an advantage in spreading homeopathy, if it is a delusion: Homeopaths are realy nice and you feel well, when being treated by them, that is a definite marketing advantage over the nasty conventional med, who does not even look at you, when asking his students, whether they think your leg has to be amputated. Quote:
Do you mean observations regarding the health of a patient? How did you notice this? Also good observation alone helps little, if the reasoning afterwards gets screwed, both have to be good. About Einstein, there is something called Bose-Einstein-statistics, Einstein did use statistics, when it was needed and i'm very sceptical, that he would have abided using statistics, if he would have ever tried to find out the truth about homeopathy, as medicine is one of the things that screams for statistics, even when looking at very basic things and therefore especially when looking at complicated things there.

(in brackets year of nobel prize, all of them are named as strong supporters of a non-deterministic view, based on the certain knowledge, that they either extended QM or drew conclusions of QM, that directly rely upon its randomness, with a lot of nobel prize winners i was not certain if they could be put into a fraction, but i guess many more are QM supporters, as the vast majority of todays physic researchers.) Hope that is enough arguing from authority for the moment. And my argument is based at worst on a "current" fashion, that is at least 60 years old. Carn |

1) Scientists design tests for things they don't understand all the time. If we could only test things we understood, we would not have gotten anywhere at all. 2) Why should homeopaths be lousy researchers? Research methodology is relatively simple text-book stuff. And IF you are right, then why exactly should we believe those lousy researchers when they say homeopathy works ?Hans

E.g. if i claimed, that some goats can fly, if at a beach in the night with a star constellation fitting the birth sign of the goat and if the energetic vibrations of the sand are a perfect match of the rolling of the waves, with the energetic vibrations of the wind being in phase with the spirit of the goat, then a researcher, who would want to test my claim, would need to know what sort of astrology i'm following, identify the correct constellations for some goats and would need to know what i mean with that babble about energetic vibrations and so on. Otherwise he could not design the correct test. Of course the simpler solution is to get hold of me, put me upon a beach together with a pack of goats and leave me a mobile, so i can call him when a good night is there. But this does not seem to work with homeopathy, though so far i'm not certain why homeopaths think it doesn't work(e.g. get homeopaths do all the diagnosing, prescribing and weighging stuff in a DBPC except for the statistical analysis.) Most simple of course would be to tell me to shut up and come back, when i have made a reliable test about my flying goats. Something that did not bring many fruits with homeopathy so far. Quote:

hi carn,
i forgot about arguing on the basis of verbosity! in which case you win, even as compared to moi. but i will skip around and answer in snippets.just one for now, the faith you put in hans' witty inquiry, why we should trust homeopaths, who are lousy researchers, regarding homeopathy: a. they are not trained to be researchers b. 'you' guys are, and still muck it up c. research methodology is simple, perhaps (which is arguable), but matching it up appropriately to the measurement of real world objects is not d. it all assumes anyway that you understand the subject, which you guys often claim is irrelevant, but you seem to acknowledge the problem, which is refreshing: "a researcher, who would want to test my claim, would need to know what sort of astrology i'm following, identify the correct constellations for some goats and would need to know what i mean with that babble about energetic vibrations and so on. Otherwise he could not design the correct test." which is largely what i've been saying about the failure of dbpc to measure well-documented effects, because you're using a yardstick that has been marked up randomly, or at least with numbers that reference processes in conventional medicine, that are not germaine to processes in homeopathy. bach

hi carn,
yeh, einstein's smarter than all of them - put together. ADD: that's why he's einstein, and they're not. they're not newton, either, nor copernicus. and i think in any alternative universe, most of them never could be. and don't be mistaken, i am not calling them stupid, just not einstein - i mean, you could take that as a 'slam' on all the other brains you've listed, but give me some credit: i'm not trying to dis' planck and company, after all! you will also remember, i acknowledged daddy einsteing was no 'patzer' at statistics himself, so you didn't really have to make that point, but still he came down on the side of determinism, and for some purposes at least recognized that statistics was a 'make do' strategy, since we were not in a position to actually observe the actual object of our desire. as far as 60 years of fashion - a blink of the eye, and a few grains of sand still disturbing your tranquility anyway, alternate visions still hanging in there. bach p.s. sorry for the late (several hours later) addition, but i didn't want to post it a second time - though maybe i should have - sorry for any confusion.

hans,
yes, scientists test for things they don't understand, all the time. and often struggle until they find a correct methodology, that fits the case. in this, statistical research is like basic research - a fairly mundane example, being the numerous unsatisfactory experiments conducted by edison, until he found a servicable filament. this is also the same process we pursue in clinical practice, analyzing data and working with it until we find the correct, or at least a servicable, understanding of a problem, and a useful intervention. needless to say, knowledge of the subject will continue to expand ... even as there have been improvements upon the original light bulb. but scientists don't test things that they don't know about. unless you think they do? unless you think they can? first they have to postulate it. or happen upon it unexpectedly, as with the discovery of aggregates of molecules produced during serial dilution. you might also try to fit carn's observations into your schema, regarding the need to understand the details of his goat universe, before one could test it. carn, can a flat earther understand orbital dynamics? the answer is 'yes,' to the extent that he can regurgitate what he has been fed, or fed himself, and even perform, possibly, sophisticated calculations. but if in his heart of hearts, he believes it's all b.s., then i propose his 'understanding' is inadequate and his demonstration of 'understanding' a facade, a sham. in short, you still have to be able to weigh the evidence appropriately, as compared, for example, to hans' position, which he has finally made explicit over at randiland, that he rejects evidence provided from clinical practice. the flat earther, by comparison, might simply indicate his belief that the curved glass of the telescope distorts your measurements. weighing the evidence is part of bias: if you believe in your 'instrumentation,' statistical or clinical or whatever, then you ascribe a certain degree of heuristic value to observations you make using that technology; if you don't believe a particular instrumentation, or methodology, is valid, then you disregard its measurements and disbelieve conclusions made on that basis, in favor of conclusions you make on the basis of your own methodology. needless to say, the 'faithful,' especially if they are scientifically inclined, can adduce countless 'facts' in support of their findings, and in support of their belief that the outcomes of their own methodology are superior to the outcomes of the other guy's methodology. ok, regression to the mean, observer bias, blah blah blah. it doesn't refute nuthin, just restates your own faith in your own mantra. bach

quote (carn): "The only thing where a "yes/no" answer is the only satisfying result is "is a sub-avagadro homeopathic remedy different from carrier substance?". Anything else but yes or no does not make sense with that question."yes, we are in agreement on this, which is why i think a proving trial is the best shot at a good trial. i have previously even stated that i thought a good trial should guarantee a positive outcome for homeopathy, but after my lengthy exchange with hans (http://www.otherhealth.com/showthread.php?t=3453&page=2) i started thinking, geeessh, the confounders are really (potentially) pretty significant even in this case, so i have modified my claim, and now say that i think that a proving trial probably should be capable of showing positive results for verum. for anything else, the record of statistical research into clinical practice of all sorts is simply, in my experience, so shoddy as to render response to your hypotheticals easy: no, whatever you come up with will not convince me to trust your method over homeopathic (or other clinical) method, because even when they seem really clever, research trials too often end up asserting outcomes that aren't justified on the basis of the actual experiment and its conceptualization, even if the numbers you guys produce appear to suggest otherwise. bach
