To piggyback on this, one of the things Jonathan Haidt has shown in his work on ideological bias is that liberals are unable to accurately understand the conservative worldview, while both conservative and moderates are able to accurately explain liberal positions.

Here's an explanation of the study:

>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.
