Sometimes one can tell. If a uniform process is not used to evaluate all claims, right away there is a possibility that something is wrong. So, for example, if up until now something has counted as “legitimate climatological science” (not necessarily correct in its conclusions, but legitimate in its methods) if it is published in Journals X, Y, and Z, and now someone want to get the world to regard Journals X, Y, and Z as no longer journals of legitimate climate science (even though the personnel running the journals is as qualified in research, degrees, publications etc. as always), and admits that the basis of this judgment is that those journals sometimes publish articles advocating a disliked minority position, one should immediately be suspicious that this someone desires to alter the process in order to exclude certain results.
Chris, have you any evidence that in the cases I mentioned (regarding polar bear counts and the Great Barrier reef), the numbers are anywhere near 99.99 and 0.01? If not, why are you inventing those numbers now?
And do you not think that sometimes the “bitter castout” might be right?
I have not said that dissenters are always right, or even usually right. But you seem to be arguing that professions can never be guilty of corruption, that officials within professions can never exercise unfair bias. And that’s naive. Emotions run very high on certain issues and subjects, and scientists are human beings with political and social agendas. I can tell you from firsthand experience that in religious studies the processes of research grants, hiring and other things are very much controlled by a group with a particular world view – left wing, feminist, deconstructionist, and if Christian, very liberal Christian – in almost every secular academic institution. But whenever anyone protests this bias, the authorities trot out all the same arguments you are using to justify squashing dissent and hiring only the like-minded. And if it happens in religion it can happen elsewhere. I’ve seen it happen in philosophy, English, and other subjects. To believe it never happens in science, when we already have evidence that it has happened in science (and you conceded to me in a private discussion that some climatologists had behaved inappropriately), would be naive.
