Not exactly correct.
Consensus is a most definitely a part of the collective scientific
effort, involving the general agreement of researchers in the particular field (which includes grunt techs with just bachelor's degrees but who do the actual work, all the way to the PhD's in the field) on the validity of the methodology, data, and interpretation of the data. If consensus had "absolutely no scientific relevance," then there would be no point in peer review, publication, conferences, etc.
Consensus changes as credible evidence from credible researchers acculumulates. At one point, the hypothesis that mitochondria and chloroplasts were once independent protobacteria that were taken into another bacteria to form a symbiotic relationship was controversial and laughed at. On the basis of credible supporting evidence, however, Lynn Margulis has swayed the consensus of scientific opinion and now we teach the endosymbiotic theory as strongly supported.
Peter Duesberg was a prominent retrovirologist and Kary Mullis is the Nobel-prize winning inventor of PCR...and both of them argue vehemently that HIV does not cause AIDS. Why aren't their arguments taken seriously? Because the scientific consensus of those in the field (myself included) was that the preponderance of data supporting the HIV-AIDS link was far stronger than their alternative hypotheses. That doesn't stop scientifically-ignorant whackjobs from citing their work.
Now, where mvscal
is 100% on the money is that polling hundreds or thousands of "scientists" regardless of their expertise in the specific topic (as has been done in the global warming debate) or citing pointless, scientifically worthless petitions is utterly without
ANY kind of merit. Polling biologists, for example, with regards to their opinions on the topic of anthropogenic CO2 is worthless - unless the biologists questioned have an actual background in the field.
Just because someone claims that they have a scientific degree doesn't mean that their opinion on a scientific topic is worth a dime. I've seen this time and again in the evolution debates. 'Thumpers LOVE to cite Michael Behe as a "big time" scientist who has "valid" arguments against natural selection and LOVE to quote arguments from his book (Darwin's Black Box). The problem is...Behe is a less-than-spectacular bio
chemist at Lehigh University who doesn't know jack shit about biological evolution and has displayed his ignorance for all to see in his book. Hell, the arguments and claims he puts forth in his book for "irreducible complexity" were disproven before his book even went to press. Not that it stops 'thumpers from citing his scientifically discredited work in debates. Hell, Jonathan Wells makes a good living by parading his questionable scientific credentials and lying about scientific data. Despite these examples, in the case of natural selection, the
scientific consensus is that across various disciplines involved (geology, evolutionary developmental biology -evo devo-, molecular biology, genetics, physiology, etc.) is that natural selection has the strongest support and is accepted.
To dismiss consensus out of hand as unscientific is inaccurate. What I believe mvscal means to disparage is the less-than-scientific poll-taking from cherry-picked indivuals or packs of "scientists" who may or may not have any expertise in what the hell they are allegedly supporting. I have to agree with mvscal that the word "consensus" is being bandied about in a way that makes it scientifically worthless.
I have little faith in conventions of researchers who already have a political axe to grind against the U.S. supporting arguments that "just happen" to blame America. I have little faith in researchers with leftist, anti-corporate bents who argue strongly for the anthropogenic causation of global warming, and little faith in right-wing, corporately-funded researchers who dismiss it out of hand. The political views of those involved color their research and their interpretations. For either side to claim that they're the politically-neutral one while the other is biased is frigging laughable. The messengers for each side are tainted, thanks to the financial and political views of all involved and the nature of the research.
