1. Illusion of Invulnerability: Members ignore obvious deficiencies (their climate models don’t work), take extreme positions (a 20 foot rise in sea level), and are overly confident in their position (the IPCC’s steadfast position in the face of a cooling planet).
2. Collective Rationalization: Members discredit and explain away any positions contrary to group thinking (only deniers and flat-earthers (and now daughter rapists) disagree with them).
3. Illusion of Morality: Members believe their decisions are morally correct, ignoring the ethical consequences of their decisions (the solution is worse than the problem: Cap & Trade will kill global economy with the poor hit hardest; ethanol = starvation; and other much worse consequences of these tunnel vision solutions to follow).
4. Excessive Stereotyping: The group constructs negative stereotypes of rivals outside the group (GW deniers are the house n-words of Big Oil).
5. Pressure for Conformity: Members pressure any in the group who express arguments against the group's stereotypes, illusions, or commitments, viewing such opposition as disloyalty (conflicting voices are not invited to climate change conferences and cannot get their research funded or published).
6. Self-Censorship: Members withhold their dissenting views and counter-arguments (the Medieval warm period was washed from the “hockey-stick” data set).
7. Illusion of Unanimity: Members perceive falsely that everyone agrees with the group's decision; silence is seen as consent (Al Gore says the scientific consensus is unanimous, never mind those 31,000 deniers).
8. Mindguards: Some members appoint themselves to the role of protecting the group from adverse information that might threaten group complacency (Al Gore defines this characteristic).
There is a reason for my hang-up with groupthink. It has been repeatedly stressed to me in my work-life that groupthink is to be avoided. It is a challenge in the nuclear industry to avoid mental traps, such as groupthink, in decision making. This is stressed in training, as well as addressed by regulation.
10 CFR Part 50.59 provides the regulatory framework for addressing changes to commercial nuclear plants. The following questions must be addressed in evaluating engineering changes to a nuke plant.
(i) Result in more than a minimal increase in the frequency of occurrence of an accident previously evaluated in the final safety analysis report (as updated);
(ii) Result in more than a minimal increase in the likelihood of occurrence of a malfunction of a structure, system, or component (SSC) important to safety previously evaluated in the final safety analysis report (as updated);
(iii) Result in more than a minimal increase in the consequences of an accident previously evaluated in the final safety analysis report (as updated);
(iv) Result in more than a minimal increase in the consequences of a malfunction of an SSC important to safety previously evaluated in the final safety analysis report (as updated);
(v) Create a possibility for an accident of a different type than any previously evaluated in the final safety analysis report (as updated);
(vi) Create a possibility for a malfunction of an SSC important to safety with a different result than any previously evaluated in the final safety analysis report (as updated);
(vii) Result in a design basis limit for a fission product barrier as described in the FSAR (as updated) being exceeded or altered; or
(viii) Result in a departure from a method of evaluation described in the FSAR (as updated) used in establishing the design bases or in the safety analyses.
Nothing approaching this level of rigor is applied to the knee-jerk solutions to a climate change problem which may not exist, or may be an environmental benefit under some criteria. Global Warming/Climate Change Groupthink has made it unnecessary to perform any rigorous analytical thinking before decisions are made.
One other thing. If you get locked into groupthink in the nuclear power business, you may just find your name listed here some day. On the other hand, Global Warming Groupthinkers may get listed with other Nobel Peace Prize winners.
