|What About It?|
"Agnotology (formerly agnatology) is the study of culturally induced ignorance or doubt, particularly the publication of inaccurate or misleading scientific data. In 1995 Robert N. Proctor, a Stanford University professor specializing in the history of science and technology, and linguist Iain Boal coined the neologism on the basis of the Neoclassical Greek word ἄγνωσις, agnōsis, "not knowing" (cf. Attic Greek ἄγνωτος "unknown"), and -λογία, -logia.
More generally, the term also highlights the increasingly common condition where more knowledge of a subject leaves one more uncertain than before. David Dunning of Cornell University is another academic who studies the spread of ignorance. "Dunning warns that the internet is helping propagate ignorance – it is a place where everyone has a chance to be their own expert, he says, which makes them prey for powerful interests wishing to deliberately spread ignorance".
In his 1999 book The Erotic Margin, Irvin C. Schick referred to unknowledge "to distinguish it from ignorance, and to denote socially constructed lack of knowledge, that is, a conscious absence of socially pertinent knowledge". As an example, he offered the labeling "terra incognita" in early maps, noting that "The reconstruction of parts of the globe as uncharted territory is ... the production of unknowledge, the transformation of those parts into potential objects of Western political and economic attention. It is the enabling of colonialism."
There are many causes of culturally induced ignorance. These include the influence of the media, either through neglect or as a result of deliberate misrepresentation and manipulation. Corporations and governmental agencies can contribute to the subject matter studied by agnotology through secrecy and suppression of information, document destruction, and myriad forms of inherent or avoidable culturopolitical selectivity, inattention, and forgetfulness.
Proctor cites as a prime example of the deliberate production of ignorance the tobacco industry's advertising campaign to manufacture doubt about the cancerous and other health effects of tobacco use. Under the banner of science, the industry produced research about everything except tobacco hazards to exploit public uncertainty.
Another example is climate denial, as illustrated in the 2012 PBS Frontline documentary Climate of Doubt, which argues that oil companies have for at least the last decade, paid teams of scientists to downplay the effects of climate change.
Tribal resistance to science that contradicts medical or dental dogma heavily biases decision making, prompting vitriolic attacks that contributes the suppression of scientific knowledge in service of protecting a sanctioned narrative. 
Agnotology also focuses on how and why diverse forms of knowledge do not "come to be", or are ignored or delayed. For example, knowledge about plate tectonics was censored and delayed for at least a decade because some evidence remained classified military information related to undersea warfare."
