Now a fascinating new book comes along that, to a liberal like myself, helps demystify the right — and illuminates the kind of messaging that might connect with voters of all stripes. “The Righteous Mind,” by Jonathan Haidt, a University of Virginia psychology professor, argues that, for liberals, morality is largely a matter of three values: caring for the weak, fairness and liberty. Conservatives share those concerns (although they think of fairness and liberty differently) and add three others: loyalty, respect for authority and sanctity…

Another way of putting it is this: Americans speak about values in six languages, from care to sanctity. Conservatives speak all six, but liberals are fluent in only three. And some (me included) mostly use just one, care for victims.

“Moral psychology can help to explain why the Democratic Party has had so much difficulty connecting with voters,” writes Haidt, a former liberal who says he became a centrist while writing the book.
