Ben Goldacre is a British physician, academic and writer. From 2003 to 2011 he wrote a science column, ‘Bad Science’ in The Guardian. The book was published in 2008.
The proposer had the book lying unread on his shelves for some years and in response to the repeated urgings of his daughter, a research scientist in the fields of immunology and cancer, had finally got around to reading it. Himself a scientist, he found that it brought to light some issues – about medical research in particular – of which he had been previously unaware.
The group’s responses to the book were predominantly positive, but one member of the group (another scientist) had once shared a stage with the author and found him somewhat overly confident and assertive about his opinions – perhaps even untrustworthy.
However, there was little disagreement with the fundamental argument of the book, which identified problems in the ways that the media presented science to a lay audience, and attacked various branches of pseudo-science such as homeopathy, the cosmetics industry and nutritionists.
Our conversation about the book tended to the diffuse and anecdotal rather than the taking of positions and counter-positions. This blog can only take the form of a rather undifferentiated list of some of the things that cropped up.
The BBC Radio Four programme ‘More or Less’ was praised for its critiques of data used by politicians and others to justify their views. Like Goldacre, the programme’s approach is to question the exact methodology lying behind tendentious statistics and factoids.
It was pointed out by a doctor among our number that in spite of the comprehensive refutation of the science behind doubts of the MMR vaccine’s safety, the issue has refused to die away. Non-scientists continue to stir up trouble (vide Donald Trump tweet from March 2014: “Healthy young child goes to doctor, gets pumped with massive shot of many vaccines, doesn’t feel good and changes – AUTISM. Many such cases!”) (Goldacre quoted another writer’s definitions of lying, truth-telling, and bullshitting, and we agreed that Trump was the perfect incarnation of the bullshitter).
The recent furore over the Volkswagen emission trials was discussed. The trials results were reported as ‘cheating’ in the media. It was suggested that if real drivers could drive in the efficient manner of the software running the engines during the trials, then the same results could be obtained. Were the low emissions reported actually ‘cheating’?
The conventional media are the chief target of Goldacre’s criticisms. One of our group had discovered the practice of paying for articles in colour supplements and advised against considering any information from such sources as reliable. Personal experience with The Times on an issue had convinced him that the broadsheets were as culpable as the tabloids in conveying misinformation.
However, he admitted that The Guardian had so far not disappointed him, in that although guilty of occasional factual errors, it did not seem to have descended to outright mendaciousness on any issue of which he had knowledge.
We agreed that contemporary social media also offered infinite examples of the abuse and distortion of information.
Richard Dawkins and George Monbiot were quoted as good writers who, like Goldacre, set out to upset and confound their opponents. It made for engaging writing when someone had an axe to grind and wrote with a kind of controlled fury. However, it was pointed out that such writers, including Goldacre, were not above using the wiles of rhetoric in making themselves persuasive. On the other hand, one of our group defended his capacity for making decisions on the basis of facts and statistics, unswayed by rhetoric.
Our doctor mentioned the medical writings of Richard Asher (1912-1969) as being superior to those of Goldacre.
We discussed various science and history pundits on television. The importance of public understanding of science was agreed upon, but nevertheless some of these popularising figures were rather irritating.
It was mentioned that the website ‘Bad Science’ was still active and one of Goldacre’s current concerns was the use of statins.
In relation to Goldacre’s examples of challenging the proponents of bad science, the danger was that it could bring those very people into prominence, and thus legitimise their views. It was felt that this was a particular difficulty for the BBC, with its obligation to provide ‘balanced’ coverage of issues. The misinformation propagated by the ‘leave’ campaign during the run up to the Brexit referendum might have been a beneficiary of such ‘balance’.
One reader questioned whether there really was a ‘golden age’ of medical discoveries which is now over, as described by Goldacre. Our scientists and our doctor concurred, but it was suggested that maybe we were now on the verge of a new period of medical advancement with gene therapy. Goldacre, writing in 2008, could not have been expected to go into this subject.
We liked Goldacre’s analysis of the positive effects – sometimes underestimated – of the placebo effect in making people feel better. One of our scientists recounted his recent period of time in China. Having a heavy cold, he was taken to a pharmacy in China where people lay on beds with drips attached. Having talked his way out of this particular treatment, he was later persuaded by a well-meaning colleague to wear a microwave heated jacket for a morning… and subsequently felt much better!
It was pointed out that people often like to see a particular doctor – the placebo effect in operation. Medicine is an art as well as a science.
Another member of the group suggested that universities seemed to be too keen to release information to the press. This was in the context of hope-inspiring cancer treatments that later proved disappointing. Those with experience of such matters identified a common process by which an academic publishes a peer reviewed paper, the public relations department at the university latches onto it and promotes it, and then the press exaggerates its significance. Where precisely does the fault lie, we wondered, when the public is mislead on the significance of some scientific discovery? The writing of the peer-reviewed paper was in itself an organisation and ordering of what one of our scientists described as ‘fumbling about in the lab’. Our human cognitive proclivity for identifying patterns where none may exist could result in misleading conclusions. Another reader raised the issue of the book’s title in this respect – ‘bad’ science could be inept or misleading (as in the research paper) or morally ‘bad’ (as in the distortions of the press).
The arguments of the book were felt to be applicable to many fields of human activity beyond medicine and science. For example, people tend to become paternalistic and defensive about ideas that they have originated or to which they have tethered their reputation.
Discussion moved onto the general gullibility of people – for example the readiness of people in the mid twentieth century to have all their teeth removed because of the ‘superiority’ of dentures.
We wondered if the data that would emerge in due course would support the recent introduction of the 20mph speed limit in many parts of Edinburgh on safety grounds.
We were interested in how different health scares took hold in different countries.
We agreed that – in principle – we should trace back the information given in media sources to its origins. Of course we don’t always have the time and motivation to do this, so we sometimes have to take the pronouncements of trusted sources at face value.
Discussion moved onto the current political campaign for the upcoming general election, and the statements made in the media. For example, a nurse had been featured on television who used a food bank – presented as a disgraceful situation – but we wondered how food banks monitored the degree of need of their clients. There was also a difference between the ‘average salary’ of a nurse, and the ‘average earnings’ of a nurse (taking into account overtime payments).
We then got onto the subject of the alleged decline of the Labour Party.
And then onto Economics.
And then onto Education.
And then onto Deep Learning (your correspondent had never heard of this).
By this time the room was in pitch darkness. Our host groped his way to the light switch and we could all see who we had been talking to. For this reason, or perhaps because we had now put the world completely to rights, we soon disbanded and made our way out into the gloaming.
