Denialism


In the sciences and in historiography, denialism is the rejection of basic facts and concepts that are undisputed, well-supported parts of the scientific consensus or historical record on a subject, in favor of ideas that are radical, controversial, or fabricated. Examples include Holocaust denial, AIDS denialism, and climate change denial. The forms of denialism present the common feature of the person rejecting overwhelming evidence and trying to generate political controversy in attempts to deny the existence of consensus.
In psychology, denialism is a person's choice to deny reality as a way to avoid believing in an uncomfortable truth. Denialism is an essentially irrational human behavior that withholds the validation of a historical experience or event when a person refuses to accept an empirically verifiable reality.
The motivations and causes of denialism include religion, self-interest, and defence mechanisms meant to protect the psyche of the denialist against mentally disturbing facts and ideas; such disturbance is called cognitive dissonance.

Definition and tactics

Anthropologist Didier Fassin distinguishes between denial, defined as "the empirical observation that reality and truth are being denied", and denialism, which he defines as "an ideological position whereby one systematically reacts by refusing reality and truth". Persons and social groups who reject propositions on which there exists a mainstream and scientific consensus engage in denialism when they use rhetorical tactics to give the appearance of argument and legitimate debate, when there is none. It is a process that operates by employing one or more of the following five tactics to maintain the appearance of legitimate controversy:
  1. Conspiracy theories – Dismissing the data or observation by suggesting opponents are involved in "a conspiracy to suppress the truth".
  2. Cherry picking – Selecting an anomalous critical paper supporting their idea, or using outdated, flawed, and discredited papers to make their opponents look as though they base their ideas on weak research. Diethelm and McKee note, "Denialists are usually not deterred by the extreme isolation of their theories, but rather see it as an indication of their intellectual courage against the dominant orthodoxy and the accompanying political correctness."
  3. False experts – Paying an expert in the field, or another field, to lend supporting evidence or credibility. This goes hand-in-hand with the marginalization of real experts and researchers.
  4. Moving the goalposts – Dismissing evidence presented in response to a specific claim by continually demanding some other piece of evidence
  5. Other logical fallacies – Usually one or more of false analogy, appeal to consequences, straw man, or red herring.
Common tactics to different types of denialism include misrepresenting evidence, false equivalence, half-truths, and outright fabrication. South African judge Edwin Cameron notes that a common tactic used by denialists is to "make great play of the inescapable indeterminacy of figures and statistics". Historian Taner Akçam states that denialism is commonly believed to be negation of facts, but in fact "it is in that nebulous territory between facts and truth where such denialism germinates. Denialism marshals its own facts and it has its own truth."
Focusing on the rhetorical tactics through which denialism is achieved in language, in Alex Gillespie of the London School of Economics has reviewed the linguistic and practical defensive tactics for denying disruptive information. These tactics are conceptualized in terms of three layers of defence:
  1. Avoiding – The first line of defence against disruptive information is to avoid it.
  2. Delegitimizing – The second line of defence is to attack the messenger, by undermining the credibility of the source.
  3. Limiting – The final line of defence, if disruptive information cannot be avoided or delegitimized, is to rationalize and limit the impact of the disruptive ideas.
In 2009, author Michael Specter defined group denialism as "when an entire segment of society, often struggling with the trauma of change, turns away from reality in favor of a more comfortable lie".

Prescriptive and polemic perspectives

If one party to a debate accuses the other of denialism they are framing the debate. This is because an accusation of denialism is both prescriptive and polemic: prescriptive because it carries implications that there is truth to the denied claim; polemic since the accuser implies that continued denial in the light of presented evidence raises questions about the other's motives. Edward Skidelsky, a lecturer in philosophy at Exeter University writes that "An accusation of 'denial' is serious, suggesting either deliberate dishonesty or self-deception. The thing being denied is, by implication, so obviously true that the denier must be driven by perversity, malice or wilful blindness." He suggests that, by the introduction of the word denier into further areas of historical and scientific debate, "One of the great achievements of The Enlightenmentthe liberation of historical and scientific enquiry from dogmais quietly being reversed".
Some people have suggested that because denial of the Holocaust is well known, advocates who use the term denialist in other areas of debate may intentionally or unintentionally imply that their opponents are little better than Holocaust deniers. However, Robert Gallo et al. defended this latter comparison, stating that AIDS denialism is similar to Holocaust denial since it is a form of pseudoscience that "contradicts an immense body of research".

Politics and science

Climate change

HIV/AIDS

is the denial that the human immunodeficiency virus is the cause of acquired immune deficiency syndrome. AIDS denialism has been described as being "among the most vocal anti-science denial movements". Some denialists reject the existence of HIV, while others accept that the virus exists but say that it is a harmless passenger virus and not the cause of AIDS. Insofar as denialists acknowledge AIDS as a real disease, they attribute it to some combination of recreational drug use, malnutrition, poor sanitation, and side effects of antiretroviral medication, rather than infection with HIV. However, the evidence that HIV causes AIDS is scientifically conclusive and the scientific community rejects and ignores AIDS-denialist claims as based on faulty reasoning, cherry picking, and misrepresentation of mainly outdated scientific data. With the rejection of these arguments by the scientific community, AIDS-denialist material is now spread mainly through the Internet.
Thabo Mbeki, former president of South Africa, embraced AIDS denialism, proclaiming that AIDS was primarily caused by poverty. About 365,000 people died from AIDS during his presidency; it is estimated that around 343,000 premature deaths could have been prevented if proper treatment had been available.

COVID-19

The term "COVID-19 denialism" or merely "COVID denialism" refers to the thinking of those who deny the reality of the COVID-19 pandemic, at least to the extent of denying the scientifically recognized COVID mortality data of the World Health Organization. The claims that the COVID-19 pandemic has been faked, exaggerated, or mischaracterized are pseudoscience. Some famous people who have engaged in COVID-19 denialism include Elon Musk, U.S. President Donald Trump, and former Brazilian President Bolsonaro.

Evolution

Religious beliefs may prompt an individual to deny the validity of the scientific theory of evolution. Evolution is considered an undisputed fact within the scientific community and in academia, where the level of support for evolution is essentially universal, yet this view is often met with opposition by biblical literalists. The alternative view is often presented as a literal interpretation of the Book of Genesis's creation myth. Many fundamentalist Christians teach creationism as if it were fact under the banners of creation science and intelligent design. Beliefs that typically coincide with creationism include the belief in the global flood myth, geocentrism, and the belief that the Earth is only 6,000–10,000 years old. These beliefs are viewed as pseudoscience in the scientific community and are widely regarded as erroneous.

Flat Earth

The superseded belief that the Earth is flat, and denial of all of the overwhelming evidence that supports an approximately spherical Earth that rotates around its axis and orbits the Sun, persists into the 21st century. Modern proponents of flat-Earth cosmology refuse to accept any kind of contrary evidence, dismissing all spaceflights and images from space as hoaxes and accusing all organizations and even private citizens of conspiring to "hide the truth". They also claim that no actual satellites are orbiting the Earth, that the International Space Station is fake, and that these are lies from all governments involved in this grand cover-up. Some even believe other planets and stars are hoaxes.
Adherents of the modern flat-earth model propose that a dome-shaped firmament encloses a disk-shaped Earth. They may also claim, after Samuel Rowbotham, that the Sun is only above the Earth and that the Moon and the Sun orbit above the Earth rather than around it. Modern flat-earthers believe that Antarctica is not a continent but a massive ice floe, with a wall or higher, which circles the perimeter of the Earth and keeps everything from falling off the edge.
Flat-Earthers also assert that no one is allowed to fly over or explore Antarctica, despite contrary evidence. According to them, all photos and videos of ships sinking under the horizon and of the bottoms of city skylines and clouds below the horizon, revealing the curvature of the Earth, have been manipulated, computer-generated, or somehow faked. Therefore, regardless of any scientific or empirical evidence provided, flat-Earthers conclude that it is fabricated or altered in some way.
When linked to other observed phenomena such as gravity, sunsets, tides, eclipses, distances and other measurements that challenge the flat earth model, claimants replace commonly accepted explanations with piecemeal models that distort or over-simplify how perspective, mass, buoyancy, light or other physical systems work. These piecemeal replacements rarely conform with each other, finally leaving many flat-Earth claimants to agree that such phenomena remain "mysteries" and more investigation is to be done. In this conclusion, adherents remain open to all explanations except the commonly accepted globular Earth model, shifting the debate from ignorance to denialism.
