Happy New Year: The cargo cults of science.

A belated Happy New Year to scientists and those who are interested in science everywhere from us. I am afraid I still don’t get why the greeting is Happy New Years on this side of the Atlantic. Am I missing more than one of them? Anyhow, we apologize for not getting round to our usual fun post this holiday, but we have both been swamped by work and other commitments so the blog has had to take a back seat. Believe it or not this stuff takes quite a bit of work!

Nevertheless, there was lots of good humour abound at the end of 2014 and I was pleased to note another bumper crop of Ignoble awards for 2014. My favourite has to be  the Arctic Science Prize for Eigil Reimers and Sindre Eftestøl, for heir ground-breaking study testing how reindeer react to seeing humans who are disguised as polar bears. Absolutely brilliant, and I definitely want some advice on writing my next grant proposal from them.

After my last posting (and reaction) I was discussing with some colleagues how a good understanding of the philosophy of science and scientific practice still seems so elusive for many people, and how organizations spring-up everywhere that mimic the real thing to take advantage of this. I would characterize this as a failure of education, and sadly the results in modern society are actually quite profound. We see examples in extremist behaviour and positions (often resulting in violence), the search for overly simple solutions to complex problems, the adoption of magical practices by intelligent individuals, and of course, the usual mischaracterization of science as the antithesis to religion. You only have to look around the news or the web for examples everyday, with Oprah and Dr. Oz championing the latest magical nutritional fads, or homeopath’s claiming they can cure ebola.

I find one of the most fascinating aspect of all this the alternatives to scientific inquiry and dissemination that masquerade as science. Years ago as an undergraduate student I studied social anthropology, and was fascinated by the phenomenon of cargo-cults, which represents a useful metaphor here. The term cargo cult encompasses a diverse range of practices that occur in the wake of contact with the commercial networks of technologically superior colonizing societies. The name derives from the belief that various ritualistic acts will lead to a bestowing of material wealth of some sort (cargo).

The best known example is from World War II where contact with the Japanese and late Americans military in the pacific  brought about a considerable transformation of the indigenous peoples of Melanesia (Ton, 2009). At the end of the war, the military abandoned the airbases and stopped dropping cargo by parachute to their units. Those technological products that had been seen or been available to the Melanesian islanders through the colonizing armies, disappeared or became in sort supply. In response, charismatic leaders arose amongst remote Melanesian populations and developed cults that promised to restore on their followers deliveries of these goods (such as food, arms, radios, vehicles etc.) The leaders explained that the cargo was really gifts from the gods or ancestors, and in attempts to get cargo to fall by parachute or land in planes or ships again, islanders imitated the same practices they had seen the military personnel use. They mimicked the day-to-day activities and dress styles of US soldiers, such as performing parade ground drills with wooden or salvaged rifles, and in a form of sympathetic magic, many built life-size replicas of aeroplanes out of straw and built mock airstrips complete with wooden control towers to encourage aircraft to land (as shown in the picture below).

Cargo-Cult

 

 

 

 

 

 

 

 

Even though the cargo never arrived the leaders maintained their cults for years as the social benefits of belonging to the group persisted, and they provided hope for the elusive products in the future. Today the original cults have almost disappeared but some cargo cults are reportedly still active today (Raffaele, 2006).

The term “cargo cult” represents a useful metaphor to describe an attempt to recreate successful outcomes by replicating circumstances associated with those outcomes. However, the circumstances mimicked are either unrelated to the causes of outcomes or insufficient to produce them by themselves (in the former case, this is an instance of the post hoc ergo propter hoc fallacy). The metaphorical use of the term was popularized by physicist Richard Feynman at a 1974 Caltech commencement speech, which later became a chapter in his book Surely You’re Joking, Mr. Feynman!, where he coined the phrase “cargo cult science” to describe activity that had some of the trappings of real science (such as publication in scientific journals) but lacked a basis in honest experimentation.

The term seems to have fallen out of common use today, but I would suggest we are seeing boom times for cargo-cult science today and its time to resurrect it. Recent examples include journals that purport to be scientific but are not (see our recent post of predatory publishing), many CAM therapies, naturopaths, and the growth of the Integrative science movement.

Times are tough for real scientists, and I sometimes think it would be easier to join the masses of new-age practitioners rather than keep up the struggle for good quality scientific health care, and be characterized as the allopathic dinosaur (soon to be extinct) in the face of the new age of integrative healthcare. The trouble is, I just can’t bring myself to nod sagely next time someone suggests that “sciencing the art sheds light on the meaning of universal living experiences…” Nor can I sign-on for this sort of nonsense for an easy academic life, as I fear it’s patients who actually loose out here. What the heck, maybe I’ll just go and build an effigies of Dr. Oz and Dora Kunz on the roof and see what happens…

Fundamental Flaws: The aftermath of the Ham vs. Nye debate

Hello all,

As many people may have noticed by now the Bill Nye (the science guy) vs. Ken Ham (creationist) debate that was webcast last week has gone somewhat viral (note, you have to fast forward through the 13 mins of pre-feed to get to the debate – can’t their web guys edit?), and many pundits have pitched in with blogs, commentary etc. Click here to see one such example of the responses.

However, virtually all of them have focused on the substantive content of the arguments rather than the nature of the argument itself. Clearly, many of the arguments made by Ham were untenable, such as refuting the huge body of scientific work that demonstrates the likely age of the earth, engineering science that notes the improbability of building a wooden ship the size of the ark that was actually seaworthy, and most significantly life-science that notes for Ham’s arguments to work in the 4000 years required we would need 11 new species being created a day to explain the diversity of life we now see on Earth.

There were many logical fallacies presented too, the ones made by Ham I noted were:

  • Appeal to Authority
  • Ad-hoc Reasoning
  • Appeal to Conviction
  • Circular Reasoning
  • Exception (special pleading)
  • Non-sequitur
  • False Dichotomy
  • Straw Man
  • Tautology

…for a good explanation of all these see our Good Science Guide in the resources section.

I also suspect many Christians were embarrassed by Ham’s attempts to present ill-conceived arguments as “science” to support Christian creationist beliefs. In my experience the majority of religious leaders and believers today do not support a literal analysis of scripture. They hold beliefs that are informed by these ancient texts but acknowledge they were written by humans well before the discovery of much of everyday established knowledge (e.g. electricity) and are therefore products of their time, and contain many errors. Attempting to present them as “the word of god” and factually accurate (as Ham did in several slides) is rather a minority and fundamentalist view. Sadly this represents the sort of thinking that is adopted by groups such as the Taliban, The National Liberation Front of Tripura, the Klu Klux Clan, and many other extremist groups.

Despite their non-sequitur, the main problem with these sort of arguments is really that you cannot refute metaphysical arguments with scientific rationale. As Karl Popper, and Bertrand Russell and many other have considered you can’t prove the unprovable and presenting unfalsifiable claims (such as a miracles occurred, or that god exists and is the creator of the universe) as scientific hypotheses is a fruitless pursuit. There can never be sufficient scientific evidence to demonstrate god does not exist (it can always be argued god exists outside our current abilities to perceive or detect him/her) and absence of evidence is not evidence of absence. All we can do is look at the arguments and take a position. The believer will adopt faith, whilst the atheist or agnostic generally adopts scientific rationale. This could not have been clearer when a viewer asked “What would make you change your mind?” Nye responded that evidence would make him a believer, whilst Ham responded that nothing would as he had unconditional faith.

So, we should consider why Ham and his followers would wish to try and promote a scientific rationale to support their position. Basically, this is an attempt to manipulate educational policy in the USA to incorporate a very specific religious ideology instead of a broad and secular curriculum, and to target the science curriculum. This I believe the main reason why Nye accepted the challenge to appear in this debate at all. Creationism is not science in any shape or form, so suggesting it should be taught in the science curriculum is very problematic, let alone supplant scientific theories such as evolution. Teaching it as a part of religious studies might make sense, but not as a viable alternative theory in the science curriculum.

Ham’s position to get creationism into the science curriculum is as good an example of new sophistry as you are likely to find, and actually seems the ultimate example of “bait and switch,” a practice that Ham actually accused the scientific community of making in his presentation. Bait and switch is a selling method in which a customer is attracted by the advertisement of a low-priced product but then is encouraged to buy a more expensive one (as the original is now unavailable). In this case Ham presents the bait by arguing that science actually supports the creationists view of the old testament account of the existence of the world, but then as the argument proceeds to switch science out for completely unscientific dogma based on scripture: the word of god, the bible explains our existence, no carnivorous animals existed before original sin, languages developed after the Tower of Babel etc. etc.

This sort of expansion of the term “science” to incorporate all forms of inquiry and explanation, and a poor public understanding of what science is (conflating science, pseudoscience and non-science) is an increasing trend, and one of the main reasons Roger and I originally set up this blog; in order to counter such anti-science agendas.

The creationists view that you can somehow separate “observational/experimental science” from “historical science” makes absolutely no sense at all, and is an invention purely designed to support the creationist position. It represents a good example of the logical fallacy of special pleading. Science deals with the present, past and future, and directly observable and unobservable entities in order to test theories, explain and predict events. If we accept Ham’s position on this, then anything that occurred before humans existed, or anything we can’t directly observe or test by experiment today cannot be explained by scientific inquiry. However, as most scientific theories assume some form of continuity of phenomena or universality (at least in our universe) science does not generally differentiate between what can be demonstrated now and what was true 6000 years ago (apart from in terms of age of the phenomenon or environmental conditions a the time). If we follow Ham’s rationale then any conclusions drawn from what Ham calls “historical science” become meaningless. This conveniently cuts off much of current scientific knowledge. including most astrophysics, paleontology, genetics, and  evolutionary biology. The solution Ham presents is to defer to scripture, but the argument as to why scripture is more accurate that the “flawed” historical science is not made. I.e. exactly why is a nearly 2000 year old text more believeable than “historical” science? Does it not suffer from exactly the same issues with verifiability as “historical” science?

Lastly I found Ham’s characterization of science as a western Christian tradition rather offensive and patronizing. He completely ignores the great Asian, Arabic and Indian historical traditions in the development of modern science. In India, Brahmagupta (ca. 598-668) a mathematician and astronomer developed the Hindu-Arabic numerical system pioneering the use of zero as a number circa 628. This is now used as the scientific standard throughout the world. The great Islamic thinker Alhazan, Ibn al-Haytham was a prime exponent of scientific thinking, making great contributions in the development of the scientific method and in the fields of physics, astronomy, mathematics and particularly optics.

In all its rather a depressing situation that the very simplistic creationist curriculum should be taught as science at all in US public schools, but sadly it still seems very widespread there. I do wish Bill Nye had tackled the fundamental philosophical problems with Ham’s presentation, but believe he probably focused on the substantive content more as he thought this would probably make more impact. On the bright side I thought Bill Nye gave an excellent, intelligent, passionate and very respectful response. He clearly won the debate in those terms, and is an inspiration to us all as a role model for science education. Cool bow-tie too!

Onwards and upwards!

Small victories for health science with Advertising Standards Canada (ASC)

Hi all,

Thought I would give a quick update on my  experiences using FishBarrel in Canada to target dubious claims and practices, where there is no scientific evidence to support them. I am pleased to report a couple of positive results with Advertising Standards Canada (ASC) for two cases I found recently of CAM practitioners making dubious claims for their practices.

A few weeks back, I almost choked on my toast at breakfast when I opened a local free-newspaper (The Delta Optimist) to find a full page of advertisements with various local CAM practitioners advertising presented as “Ask the Experts” – strangely, with no medical or nursing content. Apart from the nonsense being claimed by some, or blindingly obvious advice (the local naturopath telling people that if they eat healthily they might feel better) what also irked me was that the page was presented as a full-spread editorial exploring healthy living, not a page of paid advertising. I know, I know, I really should know better, and I don’t know why I even bother reading them either – one, a few weeks back had the shocking front-page headline “Tenants Miss Bus!” with a story of a scheduled bus that did not arrive to pick up its passengers; hardly the BBC or Al Jazeera.

Anyhow, I decided to give FishBarrel a test run and complain to the ASC and the Competition Bureau Canada (CBC) to see if I had any luck, and also with another website I had come across making unsubstantiated health claims. It only took a few minutes to make the complaint in the time it took me to finish my coffee.

Firstly, I complained about a BC based self-described dream-healer (who also appeared on TV in 2007 in on the Hour with George Stroumboulopoulos) about his faith/energy/remote healing website. He claimed his therapies were “the most effective way that we can all play an active role in our own healing.” Secondly, I complained about a local craniosacral therapist from the Ladner Birch Tree Wellness Clinic, who claimed that autism, ADD and ADHD, could be relieved with craniosacral therapy. Lastly, I complained to the Optimist had not identified the “Ask the Experts” section as advertising, but implied it was editorial content.

The CBC were not particularly helpful, and somewhat surprisingly, it seems the advertisements did not represent unfair competition (although making false claims for commercial competitive purposes is identified in their standards). However, the ASC response found against the faith-healer in respect to Clause 1 (Accuracy and Clarity) and Clause 8 (Professional and Scientific Claims) of the Code (See: http://adstandards.com/en/standards/adComplaintsreportssearch.aspx and use “Dreamhealer” as the search term in 2013 Q4 to see the ruling)  and initially against the craniosacral therapist in the provisions of Clause 1 (Accuracy and Clarity), and Clause 8 (Professional and Scientific Claims) of the Code – this is currently being appealed by the advertiser so I will update this page on the final ruling). Lastly, it found against the Optimist in  Clause 2 for (Disguised Advertising Techniques).

All of these folks have been written to and required to comply with the code in future and the cases recorded and published on the ASC website. Small beer I know, and overall probably not world-changing, but the more bad-publicity businesses get for employing inaccurate/false claims or unscrupulous advertising techniques the more likely the public are going to question their practices, standards, and motives. All in all, it gives me some hope and was, I must admit, rather satisfying!

I shall be using FishBarrel for more of this in the future, and the more people who complain about this sort of thing the better. I have also just complained to our professional regulatory body (the CRNBC) about a practitioner using their RN status to advertise and support their private commercial CAM practices, so we shall see how that goes. With the Web and tools like FishBarrel it is now quite easy to do this sort of thing, so remember, next time you see unfair, unreasonable or blatantly fraudulent advertising practice you can do the same.

Onwards and upwards,

Cheers Bernie

 Update: March 12th 2014

The appeal process has now completed for the Ladner Cranio-Sacral therapist and the ASC upheld the original complaint finding

“In the opinion of the Appeal Panel, the overall impression conveyed by the advertisement was that craniosacraltherapy is widely recognized as an effective method of treating serious conditions listed in the advertisement. The case studies submitted by the advertiser gave only anecdotal evidence that a few patients believed their symptoms were relieved as a result of the treatment. This, in the Appeal Panel’s unanimous view, is in contrast to the principal claim conveyed by the advertisement.

Because the impression conveyed by the advertisement was not supported by the evidence submitted, the Appeal Panel, therefore, confirmed the original decision of Council that the advertisement contravened Clauses 1(e) and 8 of the Code. “
