Your 'but a variable' overlooks the unprecidented

Your 'but a variable' overlooks the unprecidented critical mass of population and industrialization that has changed the 'calculus'.

Snopes does nothing BUT collate information available in the public domain that either supports or debunks claims.

I say that the preponderance of 'junk science' is promulgated from the right because corporatism, anti-intellectualism and the pejorative use of the word elite to describe education beyond the 12th grade are more often conservative phenomena/practices/policies.

Use as corporate PR[edit]

John Stauber and Sheldon Rampton of PR Watch say the concept of junk science has come to be invoked in attempts to dismiss scientific findings that stand in the way of short-term corporate profits. In their book Trust Us, We're Experts (2001), they write that industries have launched multimillion-dollar campaigns to position certain theories as junk science in the popular mind, often failing to employ the scientific method themselves. For example, the tobacco industry has described research demonstrating the harmful effects of smoking and second-hand smoke as junk science, through the vehicle of various astroturf groups.

Theories more favorable to corporate activities are portrayed in words as "sound science." Past examples where "sound science" was used include the research into the toxicity of Alar, which was heavily criticized by antiregulatory advocates, and Herbert Needleman's research into low dose lead poisoning. Needleman was accused of fraud and personally attacked.[3]

Fox News commentator Steven Milloy often invokes the concept of junk science to attack the results of credible scientific research on topics like global warming, ozone depletion, and passive smoking. The credibility of Milloy's website junkscience.com was questioned by Paul D. Thacker, a writer for The New Republic, in the wake of evidence that Milloy had received funding from Philip Morris, RJR Tobacco, and Exxon Mobil.[12][13][14] Thacker also noted that Milloy was receiving almost $100,000 a year in consulting fees from Philip Morris while he criticized the evidence regarding the hazards of second-hand smoke as junk science. Following the publication of this article, the Cato Institute, which had hosted the junkscience.com site, ceased its association with the site and removed Milloy from its list of adjunct scholars.

Tobacco industry documents reveal that Philip Morris executives conceived of the "Whitecoat Project" in the 1980s as a response to emerging scientific data on the harmfulness of second-hand smoke.[15] The goal of the Whitecoat Project, as conceived by Philip Morris and other tobacco companies, was to use ostensibly independent "scientific consultants" to spread doubt in the public mind about scientific data through invoking concepts like junk science.[15] According to epidemiologist David Michaels, Assistant Secretary of Energy for Environment, Safety, and Health in the Clinton Administration, the tobacco industry invented the "sound science" movement in the 1980s as part of their campaign against the regulation of second-hand smoke.[16]

David Michaels has argued that, since the U.S. Supreme Court ruling in Daubert v. Merrell Dow Pharmaceuticals, Inc., lay judges have become "gatekeepers" of scientific testimony and, as a result, respected scientists have sometimes been unable to provide testimony so that corporate defendants are "increasingly emboldened" to accuse adversaries of practicing junk science.[17]
