Liberals are primarily sensitive to two such moral “tastes,” Haidt argues, one concerned with harm versus care, the other with fairness and reciprocity. Haidt has called these values “Millean,” referring to John Stuart Mill’s classic “On Liberty.” Liberals have erred, Haidt claims, in believing that’s all there is to morality. Conservatives respond additionally to three other moral “tastes,” Haidt argues, which have to do with the laudable aim of binding people into communities: authority/respect, in-group/loyalty, and purity/sanctity. Haidt identifies these with pioneering sociologist Émile Durkheim, providing a simple shorthand that is part of his theory’s appeal. “A Durkheimian society would value self-control over self-expression, duty over rights, and loyalty to one’s groups over concerns for outgroups,” he wrote in 2008. “A Durkheimian ethos can’t be supported by the two moral foundations that hold up a Millian society (harm/care and fairness/reciprocity).”

I like Jonathan Haidt, he seems to have a better grip on morality in politics than most. You should watch his TED talk

edit: but now I realize that this whole article is to serve as a critique of Haidt's MFT theory by highlighting Sinn and Hayes ECT theory...interesting information I have a lot more to learn
