I am tired of pointing out leftist hypocrisy. It’s too easy. My new interest is underlying causes. Here are a few theories, and after writing them, they all seem like restatements of the same theory:
1. Thomas Sowell’s paradigm that conservatives see the world in terms of trade offs, while the left sees it in terms of good vs evil. If you believe yourself to be fighting evil, lies are more acceptable.
2. Haidt’s morality chart showing Harm-Care and Fairness as the ONLY positive dimensions of morality for radical leftists. (Sanctity, Authority, Loyalty are not only less important, but in fact, negatives.) Perhaps they are on one hand, desperate to exercise Harm-Care, and on the other indignant toward the “Sanctity” and “Authority” of the rules of debate: truth telling, consistency, precise meaning.
3. Evolutionary biology as the consilient field of all social sciences: The left is intuitively female, the right is intuitively male. If you’re exercising the moral instincts that evolved with childrearing, it makes perfect sense that you treat every impulse and whim as if it were a universal principle. We want mothers to care for babies and families in such a devoted, uncompromising way. But this moral intuition cannot be allowed to govern all of society because it’s so inconsistent and impulsive. It needs limits. The male moral intuition evolved to solve the prisoners dilemma of facing danger as a group (duty, honor, courage), and therefore, much more readily embraces “no matter what” type rules and principles.
