Scott Adams, of Dilbert fame, has an interesting post on communication between Conservatives and Liberals titled How to Persuade the Other Party. I think his observation of the difference of basis for a position has some good points. Basically, he says a Liberal’s basis of support is fairness, while a Conservative’s comes from a moral belief. Because the two groups have different foundations their arguments are not generally persuasive to the other. I recommend it as a short read.
