Such as the nature of liberalism, conservatism, materialism, idealism, etc.

"Public ignorance is not confined to political information. Sixty-nine percent of the public believe, according to a recent survey, that price increases are mainly caused by companies manipulating the market to raise their profits. Less provocative, but just as indicative of ignorance of economic affairs, only about a third of all Americans know that the Fed sets monetary policy, or even that the consumer price index measures price inflation. It is little wonder, then, that incumbent politicians are able to take credit for good economic times—regardless of the success, failure, or irrelevance of their economic policies—and that presidents cursed with bad economies usually are booted from office, even if their policies have been sound."

good clip-
Such primitive logic explains how it is that interest groups and politicians with axes to grind—or pockets to line—are so often able to gain political support for their proposals from the very public that would be hurt by those measures. Do health insurance companies restrict coverage for expensive illnesses? Then it seems plain that we need “patients’ bills of rights” that forbid this practice. The fact that such measures tend to raise insurance rates, reducing the availability of insurance, is relatively difficult to perceive.

Try engaging on the issue of alternative energy. There is such entrenched ignorance that it seems we will never get out of this mess. The greens do not realize how much they hurt the cause, and if they do, then it is because they're interest is not environmental at all, but most of us know that already.
