Dunning-Kruger effect

The Dunning-Kruger effect is a cognitive bias in which a person's incompetence denies him the metacognitive ability to recognize that very incompetence and may even delude him into considering himself to have superior competence. Meanwhile, a genuinely competent person may underestimate his competence because he falsely believes that others share his competence. The effect is an example of the Lake Wobegon effect.

Liberals frequently tend to accuse conservatives of being afflicted with Dunning-Kruger (and do so out of mockery), but observation of liberal behavior as described by multiple sources demonstrate that it is actually liberals who themselves exhibit signs of Dunning-Kruger.
