Groupthink – is it a valid argument against climate science?

"For groupthink to develop, Janis argued, several existing conditions needed to be in place. These include group cohesiveness, insularity, and a lack of procedures for the search and appraisal of information. If a group is afflicted by these conditions then there are several tell-tale signs: stereotyped views of rivals and enemies; self-censorship of doubts or counterarguments to create an illusion of unanimity; and direct pressure on any members that express strong arguments against any of the group stereotypes."
