Very Small Amount of Relevance"},"content":{"rendered":"<p>Some very strange papers have just appeared in <em>Bioethics<\/em> regarding homeopathy.\u00a0 Not so long ago, the journal <a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1467-8519.2010.01876.x\/pdf\">published a paper by\u00a0Kevin Smith<\/a>\u00a0that advanced the claim that homeopathy is not only ineffective, but ethically problematic.\u00a0 The position taken was that homeopathy &#8220;ought to be actively rejected by healthcare professionals&#8221;, and that it is in fact ethically unacceptable, not least because of concerns about it reducing the likelihood that people would seek effective healthcare, and wasting resources.\u00a0 The analysis is overtly\u00a0utilitarian, but I don&#8217;t see any particular reason why a non-utilitarian theory wouldn&#8217;t come\u00a0to essentially the same conclusions about using homeopathy, especially by public bodies.\u00a0 (For example, there seems to be a reasonable justice-based claim that could be made on behalf of taxpayers, that it&#8217;s wrong to spend their money on stuff that lacks an evidence base: it should either be redirected to stuff that has evidence in its favour, or refunded.\u00a0 This doesn&#8217;t have to be utilitarian in flavour.)\u00a0<\/p>\n<p>But while I\u00a0have no particular dispute with Smith&#8217;s paper, neither do I have any dispute with homeopaths getting a right to reply in the same journal.\u00a0 They should have this right.\u00a0 Papers could be wrong or need refining, and disinterested argument is a good way to correct errors.<\/p>\n<p>Still: scientifically speaking, homeopaths have their work cut out.\u00a0 And without the science, the ethics is going to be tricky.<!--more-->\u00a0 Several scientists throughout the blogosphere provide sterling service in debunking the claims put by homeopaths &#8211; <a href=\"http:\/\/www.dcscience.net\/\">David Colquhoun<\/a>, <a href=\"http:\/\/xtaldave.wordpress.com\/\">Xtal Dave<\/a>, <a href=\"http:\/\/www.sciencebasedmedicine.org\/index.php\/editorial-staff\/david-h-gorski-md-phd-managing-editor\/\">David Gorski<\/a>, and even some who aren&#8217;t called David, like\u00a0<a href=\"https:\/\/blogs.bmj.com\/bmj\/2012\/03\/19\/edzard-ernst-absence-of-evidence-is-not-evidence-of-absence\/\">Edzard Ernst<\/a>.\u00a0 Martin Robbins&#8217; column\u00a0in <em>The Guardian<\/em> a couple of days ago does a lovely job of showing that <a href=\"http:\/\/www.guardian.co.uk\/science\/the-lay-scientist\/2012\/apr\/17\/1\">even homeopaths aren&#8217;t particularly good at defending homeopathy<\/a>.\u00a0 From what I can tell, the commentaries and replies to Smith&#8217;s paper published in <em>Bioethics<\/em> (<a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1467-8519.2012.01947.x\/pdf\">here<\/a>, <a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1467-8519.2012.01949.x\/pdf\">here<\/a>, <a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1467-8519.2012.01950.x\/pdf\">here<\/a>, and <a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1467-8519.2012.01948.x\/pdf\">here<\/a>) would not trouble any of these commentators for too long.\u00a0 But I&#8217;m not a scientist, and so I&#8217;ll leave the scientific arguments to those better qualified &#8211; though if the apparently serious use of the phrase\u00a0 &#8220;the energy field of the patient as a whole&#8221; in Moskowitz&#8217; paper isn&#8217;t a drop-dead cert for crankiness, I don&#8217;t know what is.\u00a0 <a href=\"http:\/\/scienceblogs.com\/insolence\/2012\/04\/bioethics_falls_for_the_tell_both_sides.php\">Orac has been fast off the mark with a fisking of all four commentaries\u00a0here<\/a>, and Smith himself gets a right to respond <a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1467-8519.2011.01956.x\/pdf\">here<\/a>.<\/p>\n<p>I am, though, pretty good when it comes to\u00a0poor arguments more generally; and there&#8217;s some astonishingly poor stuff on show here.\u00a0 Take, for example, a couple of textbook blunders in Irene Sebastian&#8217;s paper.<\/p>\n<p>First, she points out that Luc Montaignier has supported the idea that homeopathy isn&#8217;t quackery &#8211; and he has a Nobel prize for having identified HIV.\u00a0 But so what?\u00a0 The fact that he&#8217;s a respectable virologist doesn&#8217;t show that he&#8217;s an authority on all science: it doesn&#8217;t even show that everything he says about virology is right.\u00a0 Given that chemistry and physics are not branches of virology, why should virological expertise imply expertise here?\u00a0 There&#8217;s nothing but an argument to authority here &#8211; made worse by the absence of any reason to suppose that the notional &#8220;authority&#8221; is an authority on the subject after all (and, IIRC, Montaignier&#8217;s comments were greeted with no small amount of derision by the scientific community: <a href=\"http:\/\/scienceblogs.com\/insolence\/2010\/11\/luc_montagnier_the_nobel_disease_strikes.php\">see here<\/a> for a blogospheric takedown.)<\/p>\n<p>Her next advocate is Gandhi.\u00a0 Seriously.<\/p>\n<blockquote>\n<p align=\"left\">Given that most users of homeopathic medicines are in fact also proponents, a conservative estimate of the number of people Dr. Smith has labeled &#8220;unethical&#8221; is 200 million.\u00a0 Mahatma Gandhi, one of the great moral visionaries of the 20th century and a strong proponent of homeopathic medicine, is also &#8220;unethical&#8221; according to Dr. Smith\u2019s logic.<\/p>\n<\/blockquote>\n<p>It&#8217;s hard to know where to start with that.\u00a0 Whatever you think about Gandhi as a moral visionary, it&#8217;s hard to deny that his biggest influence was in, er, politics.\u00a0 So quite why his endorsement of homeopathy&#8217;s effectiveness\u00a0should be taken seriously is anyone&#8217;s guess &#8211; unless you happen to think either than he was incapable of error, or that his support for something is enough to change the fabric of reality.\u00a0 (Maybe homeopaths do believe that.\u00a0 They believe that water has a memory, after all.)\u00a0 Besides: Smith&#8217;s claim is not that homeopaths are (necessarily) bad people: it&#8217;s that there is a moral problem associated with the use of homeopathy.\u00a0 That&#8217;s a very important difference to keep in mind.\u00a0 The most that he&#8217;s saying is that people who push homeopathy do something impermissible if either (a) they&#8217;re unaware of its ineffectiveness, because you ought to know whether something is effective before you push it, or (b) they are aware of its ineffectiveness, but push it anyway.\u00a0 To the extent that someone is guilty of one of these, <em>and to that extent alone<\/em>, their endorsement of homeopathy makes them morally questionable.<\/p>\n<p>Nor can you use the support of someone you admire to demonstrate the permissibility of an action, any more than you can use the support of someone you dislike to show the impermissibility of another.\u00a0 The <em>argumentum ad Gandhium<\/em> here is just as fallacious as the <em>argumentum ad Hitlerum<\/em> in other contexts, and for exactly the same reason.\u00a0 Things aren&#8217;t\u00a0a bad idea\u00a0<em>because<\/em> Hitler endorsed them (Hitler endorsed shoes, but they&#8217;re OK); if they&#8217;re a bad idea, Hitler&#8217;s endorsement is irrelevant.\u00a0 Similarly, things aren&#8217;t a good idea <em>because<\/em> Gandhi endorsed them, and nor is his endorsement evidence in their favour.<\/p>\n<p>Ho hum.<\/p>\n<p>Milgrom and Chatfield&#8217;s paper advances an even stranger argument: that Smith (and, by extension, other people opposed to homeopathy) are scientistic.\u00a0 This isn&#8217;t true, as far as I can tell.\u00a0 But even if it were, what&#8217;s the problem?\u00a0 For Milgrom and Chatfield, the problem is that,<\/p>\n<blockquote>\n<p align=\"left\">[t]aken to the extreme, scientism defaults to Internet-fueled inquisitorial intolerance which, supported by certain academics, sections of the media, and (usually anonymous) blog sites, systematically vilifies anything\u00a0considered \u2018unscientific\u2019, e.g. the campaign to undemocratically\u00a0rid Britain\u2019s NHS of its homeopathy\/CAM\u00a0facilities.<\/p>\n<\/blockquote>\n<p align=\"left\">Two things here.\u00a0 First, science is not a matter of tolerance, and nor should it be.\u00a0 Reality is not tolerant.\u00a0 Things are either true or false.\u00a0 If you&#8217;re claiming that illnesses can be cured by any treatment, the onus is on you to prove it.\u00a0 If you can&#8217;t prove it, and if the mechanism by which the cure is supposed to work is\u00a0massively improbable (and you can&#8217;t say satisfactorily how that might work), then you don&#8217;t get the same platform as things that can be proven, and the mechanism of which is scrutable.\u00a0 Noone gets special treatment.\u00a0 (For sure, a treatment not working is not the death-knell: if there&#8217;s good reason to suppose that it <em>could<\/em> work based on what we already know, then that&#8217;s an invitation to refine the treatment, and to learn something about why it doesn&#8217;t in this case.\u00a0 But homeopathy cannot claim to be plausible by the standards of what we know, so it stands or falls according to its results.)<\/p>\n<p align=\"left\">Second, the appeal to democracy is specious.\u00a0 So what if people want homeopathy?\u00a0 They also frequently want antibiotics to treat their cold.\u00a0 The NHS should not provide that, either.\u00a0 Just as science isn&#8217;t a matter for tolerance, neither is it a matter for democracy.<\/p>\n<p align=\"left\">I could go on, but this is already long.\u00a0 I might return to other aspects of the papers in future.<\/p>\n<p align=\"left\">For the time being, though, a question.\u00a0 Should the responses have been published, given their problems?\u00a0 Well, merely coming to the defence of homeopathy isn&#8217;t sufficient to veto publication; such papers should get their day in the sun.\u00a0 I am slightly more worried, though, by the fact that the authors themselves thought their responses worth publishing.\u00a0 I don&#8217;t think that any of them has done great favours for the intellectual reputation of homeopathy.<\/p>\n<p><!--TrendMD
