Similar to Logthinking, but focused on the social enforcement of logical formalism as the only permitted mode of discourse within a group. The group develops a shared dialect of syllogisms and fallacies, using it as a cudgel to win arguments rather than a tool to find truth. Appeals to experience, values, or practicality are ruled "illogical" and out of bounds, creating a sterile, hyper-rationalized echo chamber that is often logically sound but humanly obtuse.
Example: In a philosophy debate club, a member argues for compassion in ethics from a phenomenological perspective. They are swiftly shut down by the club's president: "Your argument commits the appeal to emotion fallacy. Until you can present a formal deontological or utilitarian syllogism, you have no valid point." This Logical Groupthinking privileges form over substance, ensuring only one style of thinking can be heard.
