How the growth of denialism undermines public health

Christmas is a time when many entirely rational people whose views are based solidly on empirical evidence the rest of the year suspend their critical faculties and say things they know to be untrue. Just in case any young children have picked up their parents’ copy of the BMJ, we won’t go into detail except to say that the subject of these falsehoods traditionally originates in the far north. Such stories are harmless and those telling them will, when their children reach an appropriate age, abandon the pretence. Yet other people hold views that are equally untrue and do so with an unshakeable faith, never admitting they are wrong however much contradictory evidence they are presented with.
Some of these views are harmless, but others cost lives. It is easy to think of contemporary examples. “HIV is not the cause of AIDS.” “The measles, mumps, and rubella vaccine cannot be considered safe.” “Second hand smoke is simply an irritant and there is no conclusive evidence that it is dangerous.”And, with potentially the greatest consequences for our species, “the evidence that the world is warming is inconclusive, and, if not, the evidence that global warming is caused by anthropogenic carbon emissions is unproven.”

Denialism and its history
The term “denialism” has been coined to describe this phenomenon. First popularised by the American Hoofnagle brothers, one a lawyer and the other a physiologist, it involves the use of rhetorical arguments to give the appearance of legitimate and unresolved debate about matters generally considered to be settled. The term can be traced to people who deny the existence of the Holocaust, but it has subsequently been applied much more widely. Denialism can be recognised by the presence of six key features (box). It is, however, important not to confuse denialism with genuine scepticism, which is essential for scientific progress. Sceptics are willing to change their minds when confronted with new evidence; deniers are not. Unfortunately, confusion is encouraged by the liberal use of the term, such as when the current British government uses the term “deficit deniers” to attack critics of its economic policy, a group that now includes large numbers of distinguished economic researchers, among them several Nobel laureates.

Although contemporary usage of the term is relatively recent, the concept of denialism has been recognised for several decades. A chapter entitled “Denial of reality” in a 1957 book describing the phenomenon of cognitive dissonance notes how “. . . groups of scientists have been known to continue to believe in certain theories, supporting one another in this belief in spite of continual mounting evidence that these theories are incorrect.” It highlights, in particular, the importance of selectivity, whereby “one aspect of the process of dissonance reduction [is] obtaining new cognition which will be consonant with existing cognition and avoiding new cognition which will be dissonant with existing cognition.” The extent to which selectivity influences our views is now widely recognised, not least as a result of a best selling book containing many examples of what is termed “confirmation bias.” One explanation is that confirmation bias is how we deal with evidence that challenges our strongly held beliefs and that would otherwise threaten our self perceived status as intelligent and moral individuals.
Approaches to denialism
Recent cognitive research, some taking advantage of advances in brain scanning, has shed light on the neurological processes whereby individuals interpret a message according to who is the messenger. People subconsciously suppress recognition of clearly contradictory messages from politicians that they support, yet easily identify contradictions from those they oppose.11 However, simply ignoring relevant evidence is insufficient. Evidence, including authoritative corrections, that contradicts strongly held views can, paradoxically, reinforce those views.12 Thus, research in the United States has found that registered Republicans who are exposed to evidence on the importance of social determinants of health are less likely to support collective action to address them than are those not exposed.13
Yet denialism involves more than someone accumulating a collection of individual errors in information processing. Increasingly, it takes on the form of social movements in which large numbers of people come together and propound their views with missionary zeal.14 These views combine exploitation of the genuine uncertainty that characterises scientific research with the use of simple falsehood.
Denialists emphasise the limitations of statistical associations for establishing causality, which are well recognised by aetiological epidemiologists, yet ignore other criteria that are used to ascertain whether a relationship is likely to be causal, such as biological plausibility, consistency, and strength of association. They may also try to change “the rules of the game,” such as in the now notorious example when the tobacco industry sponsored efforts to define “good epidemiology practice.” The initiative would have redefined a relative risk of less than two as being not statistically sound because of the potential for unrecognised confounding and was designed to exclude research on the risks associated with passive smoking, which typically yield a relative risk of 1.3-1.6. Other efforts seek to redefine concepts as essentially unresearchable, such as in an industry funded report on alcohol that stated: “violence is a nebulous concept.”
Selective use of the scientific literature is another approach used by denialists, who either promote methodologically flawed research that supports their world view over more methodologically sound papers or undertake intensive searches of papers they oppose for anything that might cast doubt on the quality of the science. A now notorious example is “Amazongate,” in which a report by the Intergovernmental Panel on Climate Change inappropriately referenced a statement on a report about the sensitivity of the rainforest to changes in rainfall rather than the relevant primary research. This inconsequential referencing error, in a report of more than 900 pages, was then used to undermine the entire report.
Deliberate falsehoods are rarely used to convince people that something is true, but rather are used to seed doubt about the actual truth. For example, although only 18% of Americans believe that President Barack Obama, a church going Christian, is a Muslim, an additional 43% are unsure. Media commentators don’t actually say that that Obama is a Muslim, they just say that they don’t know whether he is or he isn’t, while consistently using the president’s full name: “Barack Hussein Obama.” In the health arena, this approach is commonly found in debates about vaccines, where denialists play on the argument that “you can never be sure” when it comes to the very small risk of complications of vaccinations.

The spread of denialism

Of course, there have always been people who have held strong views in the face of overwhelming evidence to the contrary. Indeed, the Flat Earth Society, although a shadow of its former self, still exists. However, the world has changed in recent decades in three important ways, each facilitating the spread of denialism.
The first is the birth of web 2.0, which has transformed the internet from a closed publishing platform into an interactive tool allowing intensive exchange of ideas. People who might once have clung on to dissenting views in isolation can now locate individuals with similar views within seconds. Social media enable communities of denialists to grow by feeding each other’s feelings of persecution by a corrupt elite. This is encouraged by cynicism with existing political systems. In one study, for example, the people who were most likely to believe in 9/11 conspiracy theories were those who were disaffected and disengaged with the political system. Such cynicism is growing, a development that should not be surprising given how politicians feel able to take their countries to war on the basis of dubious evidence.
A second issue, in some countries, is the espousal of denialism by an increasingly partisan media, which expends considerable energy identifying supposed conspiracies that they then espouse to the general public.
The third is the growing exploitation of the first two issues by corporate interests. Although the tobacco industry has been at the forefront of such tactics, there are now examples from many other sectors, including the food and drink, asbestos, oil, and alcohol industries. Such activities received considerable official support during the administration of George W Bush, under whose aegis there were widespread attempts to politicise scientific research and advice.

Tackling denialism

So how should scientists respond to denialism? The first step is to recognise when it is present. Denialism changes the rules of the game. Conventional approaches to scientific progress—such as hypothesis generation and testing, and argument and counterargument—that seek to elicit the underlying truth no longer apply.
In some cases, nothing can or needs to be done. The persisting belief among many people that Princess Diana may have been murdered by the security services (32% of the British public in one poll), for example, has enabled some tabloid newspapers to fill many pages and has wasted much police time, but has no persisting implications for public policy.
In other areas, especially where the views reflect longstanding cultural beliefs, it may be necessary to accept that these views exist and adapt messages to take account of them when developing policies and practices. Examples include the development of health promotion campaigns to prevent the spread of HIV or to encourage the uptake of immunisation. Such campaigns are based on a detailed assessment of the beliefs that would undermine them if not confronted. For example, early programmes to tackle HIV/AIDS in east Africa had to address concerns that promotion of condoms was a covert attempt to control the population. It may be necessary to accept that there are some people who cannot be convinced, but there will be many who can.
This leaves those cases where denialist views are being promulgated actively by powerful vested interests. Here, we argue, health professionals have a responsibility to confront the denialists, exposing the tactics they use and the flaws in their arguments to a wide audience. Again, the first step is recognition. When a seemingly bizarre story appears in the media that risks undermining public health, health professionals should ask: “why is this story appearing now?” Many will, however, find this approach uncomfortable because it conflicts with the common tendency to seek compromise and avoid conflict.
Confronting denialism may also require the use of less usual methods of communication, such as analogy and narrative. Crucially, it demands speed of response. However, health authorities and non-governmental organisations are rarely able to respond rapidly, especially at weekends when, in our experience, misleading stories tend to appear in the media. Equally, editors of medical journals (with a few exceptions) often seem unable to appreciate the need to counter denialist stories.
In this paper we have looked at some of the most outrageous examples of denialism. Yet denialism is often much more subtle, and researchers are far from immune to its effects. There is a wealth of evidence on how reviewers find real or imagined flaws in papers whose messages they disagree with while discounting real errors in those they agree with. Perhaps, during the Christmas break, we, as reviewers and editors, might all take some time out to reflect on our own innate cognitive biases as well as how to overcome those of others

Characteristics of denialism

  • Identification of conspiracies: Denialists argue that scientific consensus arises not as a result of independent researchers converging on the same view but instead because researchers have engaged in a complex and secretive conspiracy. They are depicted as using the peer review process to suppress dissent rather than fulfil its legitimate role of excluding work that is devoid of evidence or logical thought.
  • Use of fake experts: It is rarely difficult to find individuals who purport to be experts on some topic but whose views are entirely inconsistent with established knowledge. The tobacco industry coined the term “Whitecoats” for those scientists who were willing to advance its policies regardless of the growing scientific evidence on the harms of smoking
  • Selectivity of citation: Any paper, no matter how methodologically flawed, that challenges the dominant consensus is promoted extensively by denialists, whereas any minor weaknesses in papers that support the dominant position are highlighted and used to discredit their messages.
  • Creation of impossible expectations of research: This may involve corporate bodies sponsoring methodological workshops that espouse standards in research that are so high as to be unattainable in practice.
  • Misrepresentation and logical fallacies: An extreme example of this characteristic is the phenomenon of reductio ad hitlerum, in which anything that Hitler supported (especially restrictions on tobacco) is tainted by association. Other methods of misrepresentation include using “red herrings” (deliberate attempts to divert attention from what is important), “straw men” (misrepresentation of an opposing view so as to make it easier to attack), false analogies (for example, because both a watch and the universe are extremely complex, the universe must have been made by some cosmic watchmaker), and excluded middle fallacies (in which the “correct” answer is presented as one of two extremes, with no middle way. Thus, passive smoking causes either all forms of cancer or none, and as it can be shown not to cause some it must, it is argued, cause none).
  • Manufacture of doubt: Denialists highlight any scientific disagreement (whether real or imagined) as evidence that the entire topic is contested, and argue that it is thus premature to take action.

  2. I really enjoyed the Yale speech. To Seth, to JTD, to Snout and the other sane commentators: keep fighting the good fight, fellas.

    World AIDS days is a great day to sit back and evaluate your contribution to cause. It's easy to get tired of the endless rebuttals met with shifting goalposts and cherry-picked arguments. But think, for every post you've made that's one more item for people searching for genuine AIDS advice to read. One more protest against the needless and senseless waste of life the denialists propagate.

    Keep it up, fellas.

  3. The basic unit of propagation of denialism is the argumentoid. Argumentoids, are units of rhetoric that – like other memes - readily propagate from mind to mind, particularly over the internet, but also via other media and by direct personal contact.

    They are almost impossible to eradicate, but improving education may help to increase resistance to denialist argumentoids improving people's critical ability to distinguish fact from rhetoric. This is particularly important for journalists, who can easily become the unwitting vectors of denialist argumentoids if they fail to recognize their essentially empty rhetorical nature, or if they place misguided importance on “seeing every side” or on “controversy” for its own sake.

    Arguing with denialists is tedious and rarely of any benefit except to the uncommitted bystander, because denialists are not honest brokers in debate, and often have astounding stamina backed by a vast store of argumentoids accumulated on denialist websites over many years. As with other pseudoscientists, “debate” is seen merely as an opportunity to recycle these already discredited canards to new audiences. The copy-paste functions make this easy on the internet, and it usually takes many times more effort to refute a lie than to tell it in the first place.

    Fast-spreading denialist argumentoids are often posed as hanging questions - often including an unstated false premise - and subtly invite the recipient to fill in the gaps. For this reason they are most effectively transmitted to people with a low baseline knowledge of the relevant science and a tendency to drawing simplistic or black and white conclusions. The Dunning Kruger effect is important here.

    The film House of Numbers, for example, is almost entirely structured in this way.

    Based on the Hoofnagles’ excellent 2007 article on denialism blog and on other experience, a basic taxonomy of denialist argumentoids and other rhetorical strategies is as follows:

    1. Simple blatant falsehoods
    1.1 Historical lies
    1.2 Demonstrably false “facts”
    1.3 Basic scientific and mathematical howlers
    1.4 Misrepresentations of key literature/data

    2. Logical fallacies
    2.1 Strawman
    2.2 Excluded middle
    2.3 Inappropriate analogy
    2.4 Red herrings
    2.5 False inference
    2.6 Over generalisation
    2.7 Misuse of “ad hominem”
    2.8 Semantic confusion

    3. Selectivity
    3.1 Cherry picking outlier data
    3.2 Use of flawed papers
    3.3 Cherry picking rough estimates with large ranges of error
    3.4 Rehashing outdated or discredited hypotheses
    3.5 Quote mining
    3.6 Unverifiable personal anecdote

    4. Setting an impossible or impracticable standard in “debate”
    4.1 Demanding 100% certainty
    4.2 Rejecting weight of evidence while demanding absolute “proof”
    4.3 Demanding non-existent data
    4.4 Single study fallacy
    4.5 Moving goalposts
    4.6 Gish gallop
    4.7 Death by copy-paste

    5. Manufacture of doubt
    5.1 “Two sides to every question” fallacy
    5.2 Slippaging a settled question into one with genuine controversy
    5.3 Overstating range of genuine controversy
    5.4 Passing off advocacy as “just asking questions”
    5.5 Galileo gambit

    6. Promoting fake experts
    6.1 with irrelevant credentials
    6.2 with fake credentials
    6.3 Manufacturing an illusion of peer regard
    6.4 Pretending to be a substantial scientific group
    6.5 Inventing non-existent "cast iron" scientific rules
    6.6 Misrepresenting genuine experts

    7. Conspiracy and dog whistling
    7.1 Us versus them – appeal to social affiliation
    7.2 Claiming personal persecution
    7.3 Claiming that work is “suppressed” rather than poor quality
    7.4 Blurring with genuine social and political injustice: racism, sexism, homophobia, etc
    7.5 Appeal to unrealistic ideals of entitlement
    7.6 Appeal to ignorance – “knowledge monopolies”

    Perhaps readers might like to add to the list.

  4. Snouts great wisdom, another cut and paste job straight from $eth no less. Still it's par for the course as everything he posts is cut and paste job, usually from AIDSTRUTH.

    And luke said it best when he called it a "Cause". Like all fundamentalists you view yourselves on a mission. And like all fundamentalists you don't let the truth get in the way of your version of events.

    You've twisted the rules of biology much like zealots twist the Koran on ideological grounds.

  5. It has been a couple years since Christine Maggiore died of AIDS. Has this had any impact on their movement? It looks like the quacks and frauds don't stop, but it also looks like the AIDS Denialism movement is quieter. I am wondering what you and your readers think?

    Also, you had mentioned that AIDS Denialism is part of a mental illness.. or will be. Is there an update on this?

    Thanks

  6. I wrote a satirical article on AIDS denial, 4 years back when I was a naive, young chem undergrad who could not understand how you could deny the existence of a disease in an era where we can take actual photographs of it in action. Between then and now, there have been huge and amazing advances in HIV research, but you would not know it if you talked to the average AIDS denier. They are still stuck in the 1980s. It's always "AZT", "Montagnier admits his proof isn't ironclad," "Gallo is a Liar," "Gay Men". The biggest proof against them is that the world moved on, and they are still ranting in the past.

    The only question is whether people are still listening. I think the biggest difference is that South Africa is no longer listening to them, now that Mbeki is out of power. That was the one country where they really held sway. I can't judge as to the number of private citizens who still listen to them.

  7. Hi notElon
    Thanks for commenting. It is hard to know just how many people listen to AIDS Deniers. Having followed this for a few years now, inside and out, it is pretty clear to me that a small number of people pay any attention to them. But there have a following, and it is seems to be growing.

    Most people recognize them for what they are...quacks, frauds, pseudoscientists, etc. Those who are duped by denialists are unable to cope with an HIV diagnosis - their own or someone they love. It is a mental health problem for sure. My view is that just one person who falls for their fraudulent claims is too many. That is why I have this blog. It is also why I wrote my book.
    Thanks again for commenting!

  8. Pete:

    You asked if the death of Christine Maggoire had any detrimental effect on the denialist movement. The answer is no, because she obviously didn't die of AIDS. How can one die of an imaginary ailment? She instead died from stress, possibly caused by a TV show or the tragic and totally unpreventable death of her daughter. Or maybe she died of plain old pneumonia, unrelated to AIDS. Or maybe she caved under the pressure of the evil orthodoxy and started taking toxic AIDS medication which ultimately lead to her death.

    It's hard to believe, but these are just some of the explanations denialists bandy among themselves to account for the death of their poster girl. How else could such a vibrant, healthy woman deteriorate over such a short period? Not AIDS, obviously. Never that.

    The most damning proof that Christine Maggoire's death did not affect the denialist movement is that they've picked up yet another poster child. Karri Stokely is one of the latest held up as an example of the great AIDS conspiracy: supposedly HIV+ and yet in great health. Except, of course, she isn't. Check out this blog's article on her from a couple of months ago: http://denyingaids.blogspot.com/2010/09/how-aids-denialism-can-kill-you-part-v.html.

    Ultimately we come back to the heart of the issue: denial. Once you've insulated yourself against the truth to such an extent as to deny the existence of AIDS then I imagine it's relatively easy to justify something small like one individual's death. People die all the time, of thousands of ailments. Far easier to blame one woman's death on something unrelated than to admit you were wrong. Christine Maggoire's death was explained away and forgotten just as Karri Stokely's untimely and preventable death will be soon.

  9. I forgot about Kim Bannon. And Lambros Papantoniou. Oh, and Jerry Colinard, Boyd Ed Graves, John Kirkham and a score of other prominent denialists who are, unfortunately, no longer with us.

  11. notElon, it may be more than is generally assumed, most people who embrace AIDS denial do so quietly and when they are harmed nobody records it. Perhaps the AMA should be encouraged to survey their doctors about the extent to which they've encountered AIDS denial in their practices.

    A friend of mine had IV Vit C (4 lots) and I opted for IV Glutathione ( 5ml once week for 6 weeks) My research indicates the two should not be combined. We both reckon wellbeing is vastly improved, altho his labs show basically the same numbers ( cd4 11) Whereas my cd4s jumped from 50s to 104. Many say numbers bounce around and are meaningless, but I have found mine are very consistant.
