Nick, Referring to your *What are the properties of good GroupThought: i.e., Group Thought that is likely to survive experience into the deep future?*
How does one define the "good" in "good GroupThought"? It obviously depends on the context. I want to refrain, for now, it could be part of another discussion, from commenting on cases where the "good" in "good thought" involves moral judgment. For now, I want to restrict the context where it involves measurable judgments or falsifiable hypotheses. If the result of the group's thinking is measured against objective criteria the "goodness" can be measured. An example of where groupthink went spectacularly wrong is in the groupthink of the quantum mechanics' experts in the 1920's rejecting the guiding wave theory. Especially after John von Neumann "proved" that hidden variables are inconsistent with the mathematics. The guiding wave theory requires hidden variables. The unknown Grete Hermann showed the wrong assumptions of von Neumann's proof, but the groupthink of the time rejected her findings and accepted the expert von Newman's proof. In the 1960's John Bell showed that Hermann was right and von Neumann wrong. Although the guiding wave theorem is considered incomplete today (as opposed to "wrong"), rejecting the groupthink of the 1920's up to 1960's, and accepting Grete's criticism of von Newmann's work, lead to today's accepted standard model of particle physics. One could argue that almost half a century of progress in particle physics was lost to groupthink and accepting an expert's judgment? There are simple principles to guide against groupthink and nurture constructive interaction that leads to wisdom of the crowd. a) One is to never soft punish people that reject conventional thinking, even if the conventional thinking is supported by the views of experts. b) Emphasize objective tests and insist on falsifiable hypotheses. I referred to Philp Tetlock in a previous post, and want to that again. He has achieved amazing success in establishing what to do to get good judgment. I want to recommend to those that are interested in this topic to read up on his work. As a final point of this post, I want to mention that I experienced the replies to me challenging the accepted scientific views on climate change as contributing to the wisdom of the crowds and not groupthink. I was not punished for rejecting the conventional thinking.
