One of the negative conditions under which modern scientists labour is "groupthink". To be fair, it has always been the case that consensus science, which is sometimes referred to as the ruling paradigm, substantially controls the contemporary settled scientific views of the day. [See Thomas Kuhn, The Structure of Scientific Revolutions (Chicago: The University of Chicago Press, 1962,1970)].
However, the power and control of the ruling consensus varies over time. There is evidence that at present the power of groupthink in science is waxing, rather than waning. On the other hand, it is precisely when the reigning paradigm begins to crack and falter that the establishment's opposition to challenges becomes both frenetic and febrile. And it certainly has at the moment. So, it is possible the frenetic character of attacks upon the non-consensus view betray the insecurity of the establishment.
We have just had a small indication of this in New Zealand. NIWA--a government run and funded science agency--representing "official science"-- announced that it will no longer fund its employees' membership subs to an independent association of scientists called The New Zealand Association of Scientists. (NZAS)
NIWA is refusing to pay membership fees for its staff to belong to the Association of Scientists, saying the group actively lobbies against science and the integrity of scientists. The National Institute of Water and Atmospheric Research notified its staff of the policy change this month. [Radio NZ]Re-read the quoted paragraph.
