They Really Do Hate Us

Todd Zywicki reviews Jonathan Haidt's book on psychology and politics. Two interesting points. First, Haidt singles out five "vectors" of social morality or values and finds Liberals care about only two of the five, whereas Conservatives tend to value all five:
Initially for Haidt what he focused on was ideas of “disgust.” Over time that has broadened and he describes five key vectors or values of psychological morality: (1) care/harm, (2) fairness, (3) loyalty, (4) authority, and (5) sanctity. Haidt finds in his research that self-described “conservatives” tend to value all five vectors of morality (as he defines them). Liberals, by contrast, place a high value on “care” and “fairness” and a lower value on loyalty, authority, and sanctity. On the two values that conservatives and liberals both value (care and fairness) they do not define those terms the same way, although they both value them according to their different definitions.
Secondly, conservatives can understand liberals, but liberals can't understand conservatives.
One other point that I find really interesting and important about Haidt’s work is his findings on the ability of different groups to empathize across these ideological divides. So in his book (p. 287) Haidt reports on the following experiment: after determining whether someone is liberal or conservative, he then has each person answer the standard battery of questions as if he were the opposite ideology. So, he would ask a liberal to answer the questions as if he were a “typical conservative” and vice-versa. What he finds is quite striking: “The results were clear and consistent. Moderates and conservatives were most accurate in their predictions, whether they were pretending to be liberals or conservatives. Liberals were the least accurate, especially those who describe themselves as ‘very liberal.’ The biggest errors in the whole study came when liberals answered the Care and Fairness questions while pretending to be conservatives.” In other words, moderates and conservatives can understand the liberal worldview and liberals are unable to relate to the conservative worldview, especially when it comes to questions of care and fairness.
In short, Haidt’s research suggests that many liberals really do believe that conservatives are heartless bastards–or as a friend of mine once remarked, “Conservatives think that liberals are good people with bad ideas, whereas liberals think conservatives are bad people”–and very liberal people think that especially strongly. Haidt suggests that there is some truth to this.

And why would that be? RTWT.  Filing this under "perky little tyrants" because:
As an aside, I think the “thinness” of the liberal moral worldview may explain a phenomenon that has puzzled me, which is the speed at which liberal views harden into orthodoxy and the willingness of liberals to use various forms of compulsion to enforce that orthodoxy.
Not sure I buy the psychological explanation. Always be suspicious of efforts to reduce free persons to behaviorist automatons. I suspect Hayek's Road to Serfdom explains the phenomenon better than Haidt. But it's still interesting that sociology/psychology can measure the closedness of the typical liberal mind.
