The religious fervour of homeopathy fans

A couple of weeks ago I put up a blog item on Huffington Post, suggesting that it would be a good idea if alternative remedies, like cigarette packets, had to carry a health warning.

In some cases this was because there were reports of a high percentage of herbal remedies not containing the requisite herb, and sometimes containing fairly dubious contents that could be harmful. And in others, such as homeopathy, it was more because there was a danger of using a homeopathic remedy, and as a result not taking medication that actually does something. So I suggested a suitable warning for a homeopathic product might be something like:
WARNING -- contains no active ingredients. If taken in place of medical treatment could result in harm or death
Now it would be disingenuous of me to suggest that I didn't expect a certain amount of negative response. I was sure it would bring the homeopathy supporters out of the woodwork and it has. I'll go into some of the specific kinds of response in a moment, but the thing I was really quite surprised by (but probably shouldn't have been) was how close some of these responses were to someone defending their religious faith.

I expect, in a contentious area of science, that there will be arguments. So, for instance, if I were to say that I rather hope MOND (modified Newtonian dynamics) can be made to work rather than dark matter as an explanation of the gravitational effects blamed on dark matter (which is true), I could sensibly expect cosmologists/astrophysicists to weigh in with the scientific arguments as to why dark matter is a better bet. But that's not what happened here at all. What I should have been seeing is a) a good explanation for the mechanism of homeopathy (as I claimed there wasn't one) and b) a good collection of large scale, double blinded trials undertaken by experienced professionals that came out in favour of homeopathy being more than a placebo effect. Neither of these things happened.

In practice, the science isn't contentious about homeopathy - it's fairly straight forward. And so, instead, arguments fell into these broad categories:

  • The report you mention only uses big studies - and this is a bad thing because? Good big studies give more statistically reliable results that good small studies - that's inevitable. If you don't understand this, take a statistics course, please.
  • Making snide remarks - ad hominem attacks are the last resorts of those who have no good arguments. When I see things like 'Thanx [sic] for embarrassing yourself even more' and 'pointing out your egregious ignorance and prejudice in regard to the topic' I know I've hit a raw nerve, because clearly there is a total inability to answer my two key points above.
  • Attack allopathic [sic] medicine - there's a technical term for 'allopathic medicine': it's 'medicine'. However the real point here is that you can't defend something by attacking something else. (E.g. 'Rx drugs are toxic, and RCTs have proven that 50% of the drug trials cannot explain the method of action.') I know the huge amount of good done by modern medicine, and know plenty of people whose lives have been saved or improved by it. But even if every real doctor doing real medicine made all their patients worse, it wouldn't make alternative remedies any better. It's a bit like responding to a restaurant critic who says the food in your restaurant is bad by saying 'Yes, but the food in McDonald's is really bad.' So?
It was also fascinating that at least four of the comments were by the same person, someone called Dana Ullman who strangely enough, according to Google is a 'proponent in [sic] the field of homeopathy. Ullman received his MPH from the University of California at Berkeley, and has since taught homeopathy and integrative health care.' So he's not at all biassed, unlike me, as I don't make any money from either alternative remedies or real medicine.

The sad thing is that in all those comments, none of the supporters of homeopathy could address my two key points (or even tried - randomly mentioning the existence of trials without citing them, when meta-studies like the Australian government one have a very clear outcome is not trying). And none seemed to actually realise the point is not that we need a warning that homeopathic remedies (unlike some other alternative therapies) can harm you, but that using them instead of things that work to treat dangerous diseases (there are homeopathic remedies for malaria, for instance, one of the world's biggest killer diseases) really does put people's lives and health at risk.

In the end, as I mentioned above, these weren't logical or scientific arguments I was presented with but rather statements of faith. And that should be a bit embarrassing for those concerned.

  1. Madsen Pirie's book ‘How to Win Every Argument’ (which I reviewed briefly at: http://gruts.com/books/pirie-how/) is an entertaining read, describing the different sorts of tricks/logical fallacies people invoke when trying to defend the indefensible.

  2. I have made the same observations regarding the "homeopathy" debate myself. I have pointed out the similarity in the method of argument from young earth creationist and supporters of homeopathy. It is also disconcerting that in more recent times, the homeopaths have tried to claim that they are the scientists and their beliefs are evidenced based, and presumably therefore the 99% + of real scientists have got it wrong. Very similar in my mind to "creation science". I'm a pharmacologist myself but if anything could attract me to psychology, this would.

Is 5x3 the same as 3x5?

The Internet has gone mildly bonkers over a child in America who was marked down in a test because when asked to work out 5x3 by repeated addition he/she used 5+5+5 instead of 3+3+3+3+3. Those who support the teacher say that 5x3 means 'five lots of 3' where the complainants say that 'times' is commutative (reversible) so the distinction is meaningless as 5x3 and 3x5 are indistinguishable. It's certainly true that not all mathematical operations are commutative. I think we are all comfortable that 5-3 is not the same as 3-5.  However. This not true of multiplication (of numbers). And so if there is to be any distinction, it has to be in the use of English to interpret the 'x' sign. Unfortunately, even here there is no logical way of coming up with a definitive answer. I suspect most primary school teachers would expands 'times' as 'lots of' as mentioned above. So we get 5 x 3 as '5 lots of 3'. Unfortunately that only wor

Why I hate opera

If I'm honest, the title of this post is an exaggeration to make a point. I don't really hate opera. There are a couple of operas - notably Monteverdi's Incoranazione di Poppea and Purcell's Dido & Aeneas - that I quite like. But what I do find truly sickening is the reverence with which opera is treated, as if it were some particularly great art form. Nowhere was this more obvious than in ITV's recent gut-wrenchingly awful series Pop Star to Opera Star , where the likes of Alan Tichmarsh treated the real opera singers as if they were fragile pieces on Antiques Roadshow, and the music as if it were a gift of the gods. In my opinion - and I know not everyone agrees - opera is: Mediocre music Melodramatic plots Amateurishly hammy acting A forced and unpleasant singing style Ridiculously over-supported by public funds I won't even bother to go into any detail on the plots and the acting - this is just self-evident. But the other aspects need some ex

Mirror, mirror

A little while ago I had the pleasure of giving a talk at the Royal Institution in London - arguably the greatest location for science communication in the UK. At one point in the talk, I put this photograph on the screen, which for some reason caused some amusement in the audience. But the photo was illustrating a serious point: the odd nature of mirror reflections. I remember back at school being puzzled by a challenge from one of our teachers - why does a mirror swap left and right, but not top and bottom? Clearly there's nothing special about the mirror itself in that direction - if there were, rotating the mirror would change the image. The most immediately obvious 'special' thing about the horizontal direction is that the observer has two eyes oriented in that direction - but it's not as if things change if you close one eye. In reality, the distinction is much more interesting - we fool ourselves into thinking that the image behind the mirror is what's on ou
