Conservatives value loyalty over truth, fairness, justice, etc.

“Liberals have a kind of moral vision based almost entirely on the Care and Fairness foundations. Conservatives, in contrast, draw on those plus Loyalty, Authority, and Sanctity, which makes their moral matrix broader.”

“This emphasis on loyalty, particularly to country and in-group, helps explain why conservatives are more likely to value patriotism and support for the military, while liberals are more likely to question those things when they conflict with compassion or justice.”

-- (Haidt, 2012, The Righteous Mind, Chapter 7)
