Republicans understand moral psychology. Democrats don't. — Jonathan Haidt

Anyone who values truth should stop worshipping reason.

Omnivores therefore go through life with two competing motives: neophilia (an attraction to new things) and neophobia (a fear of new things). People vary in terms of which motive is stronger […]: Liberals score higher on measures of neophilia (also known as "openness to experience"), not just for new foods but also for new people, music, and ideas. Conservatives are higher on neophobia; they prefer to stick with what's tried and true, and they care a lot more about guarding borders, boundaries, and traditions.

Egalitarianism seems to be rooted more in the hatred of domination than in the love of equality per se.
