We blame today's values and beliefs for this. It's human culture rather than some inherent human nature that makes us foolish in groups.
Concern for the environment is an example (of an illogical idea to be viewed with disdain). The problem with it is that it implicitly accepts society as it is. Even if an environmentalist is radical enoughto propose banning private automobiles, this would require the capability to make people act collectively,which is the realm of social design. Focusing on a tangential issue such as saving the environment can only produce cosmetic changes.
Anything that expects to survive in this world must demonstrate competitive advantage. Evolution shows that traits that persist are not those that appeal to the majority. Instead, each new trait starts out alone. Thus, the eye did not evolve by advertising that it was an organ that would benefit everyone. Each evolutionary step leading to the eye depended on the ability of a few individual organisms to outcompete the rest of the population.
Our competitive advantage is the ability to function logically as a group without internal competition.
Reticence Society wants you to be talkative, so you can persuade people, make friends / connections,rise up in the pecking order, etc. You are not judged on the correctness of you ideas, but on argumentative skills, who you know, and what you know. As a social designer, these qualities are not just irrelevant, they are counterproductive because talkative people tend to introduce more distracting ideas take effort to disprove and dismiss. As one of the first social designers, it is crucial to possess the ability to disagree with irrelevant ideas and less important to fit in to agree with the majority.
Parsimony Society wants you to spend on things you don't need. That's to ensure you spend your lifeworking for a living.
Intolerance Society wants you to be tolerant and accepting. You're allowed to disagree on tangential issues, but never on core values and beliefs. We need those who are arrogant enough to do a complete social redesign (create a monomaniacal ideology grounded in memetic defense).
