Keith Kahn-Harris at The Guardian: “…Denialism is an expansion, an intensification, of denial. At root, denial and denialism are simply a subset of the many ways humans have developed to use language to deceive others and themselves. Denial can be as simple as refusing to accept that someone else is speaking truthfully. Denial can be as unfathomable as the multiple ways we avoid acknowledging our weaknesses and secret desires.
Denialism is more than just another manifestation of the humdrum intricacies of our deceptions and self-deceptions. It represents the transformation of the everyday practice of denial into a whole new way of seeing the world and – most important – a collective accomplishment. Denial is furtive and routine; denialism is combative and extraordinary. Denial hides from the truth, denialism builds a new and better truth.
In recent years, the term has been used to describe a number of fields of “scholarship”, whose scholars engage in audacious projects to hold back, against seemingly insurmountable odds, the findings of an avalanche of research. They argue that the Holocaust (and other genocides) never happened, that anthropogenic (human-caused) climate change is a myth, that Aids either does not exist or is unrelated to HIV, that evolution is a scientific impossibility, and that all manner of other scientific and historical orthodoxies must be rejected.
In some ways, denialism is a terrible term. No one calls themselves a “denialist”, and no one signs up to all forms of denialism. In fact, denialism is founded on the assertion that it is not denialism. In the wake of Freud (or at least the vulgarisation of Freud), no one wants to be accused of being “in denial”, and labelling people denialists seems to compound the insult by implying that they have taken the private sickness of denial and turned it into public dogma.
But denial and denialism are closely linked; what humans do on a large scale is rooted in what we do on a small scale. While everyday denial can be harmful, it is also just a mundane way for humans to respond to the incredibly difficult challenge of living in a social world in which people lie, make mistakes and have desires that cannot be openly acknowledged. Denialism is rooted in human tendencies that are neither freakish nor pathological.
All that said, there is no doubt that denialism is dangerous. In some cases, we can point to concrete examples of denialism causing actual harm. In South Africa, President Thabo Mbeki, in office between 1999 and 2008, was influenced by Aids denialists such as Peter Duesberg, who deny the link between HIV and Aids (or even HIV’s existence) and cast doubt on the effectiveness of anti-retroviral drugs. Mbeki’s reluctance to implement national treatment programmes using anti-retrovirals has been estimated to have cost the lives of 330,000 people. On a smaller scale, in early 2017 the Somali-American community in Minnesota was struck by a childhood measles outbreak, as a direct result of proponents of the discredited theory that the MMR vaccine causes autism, persuading parents not to vaccinate their children….(More)”.
