[1] Denialism is an essentially irrational action that withholds the validation of a historical experience or event when a person refuses to accept an empirically verifiable reality.
[2] In the sciences, denialism is the rejection of basic facts and concepts that are undisputed, well-supported parts of the scientific consensus on a subject, in favor of ideas that are radical, controversial, or fabricated.
[5] 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.
[10] 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.
[13][14][15] 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".
These tactics are conceptualized in terms of three layers of defence: 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".
[10] Edward Skidelsky, a lecturer in philosophy at Exeter University writes that "An accusation of 'denial' is serious, suggesting either deliberate dishonesty or self-deception.
[25][26][27]: 170–173 To a lesser extent, climate change denial can also be implicit when people accept the science but fail to reconcile it with their belief or action.
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.
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.
Modern flat-earthers believe that Antarctica is not a continent but a massive ice floe, with a wall 150 feet (46 m) or higher, which circles the perimeter of the Earth and keeps everything (including all the oceans' water) from falling off the edge.
[55] 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.
[69][70][71][72] The legal and regulatory status of GM foods varies by country, with some nations banning or restricting them, and others permitting them with widely differing degrees of regulation.
Cardiologist Steven Nissen at Cleveland Clinic has commented "We are losing the battle for the hearts and minds of our patients to Web sites..."[78] promoting unproven medical therapies.
Harriet Hall sees a spectrum of statin denialism ranging from pseudoscientific claims to the understatement of benefits and overstatement of side effects, all of which is contrary to the scientific evidence.
A minority of professional researchers see disorders such as depression from a sociocultural perspective and argue that the solution to it is fixing a dysfunction in society, not in the person's brain.
In attempting to revise the past, negationists are distinguished by the use of techniques inadmissible in proper historical discourse, such as presenting known forged documents as genuine, inventing ingenious but implausible reasons for distrusting genuine documents, attributing conclusions to books and sources that report the opposite, manipulating statistical series to support the given point of view, and deliberately mistranslating texts.
[88][89] Armenian genocide denial is the negationist claim that the Ottoman Empire and its ruling party, the Committee of Union and Progress (CUP), did not commit genocide against its Armenian citizens during World War I—a crime documented in a large body of evidence and affirmed by the vast majority of scholars.
[91][92] The perpetrators denied the genocide as they carried it out, claiming that Armenians in the Ottoman Empire were resettled for military reasons, not exterminated.
[93] A critical reason for denial is that the genocide enabled the establishment of a Turkish nation-state; recognizing it would contradict Turkey's founding myths.
[101] Sonja Biserko, president of the Helsinki Committee for Human Rights in Serbia, and Edina Bečirević, the Faculty of Criminalistics, Criminology and Security Studies of the University of Sarajevo have pointed to a culture of denial of the Srebrenica massacre in Serbian society, taking many forms and present in particular in political discourse, the media, the law and the educational system.
Anyhow, this represents a notable advance in comparison with the lack of studies published in recent years in scientific journals by those companies.Krimsky, Sheldon (2015).
Here, we show that a number of articles some of which have strongly and negatively influenced the public opinion on GM crops and even provoked political actions, such as GMO embargo, share common flaws in the statistical evaluation of the data.
