The Dunning–Kruger Effect

Bryce wrote this as a comment a while back but it should be a formal blog post so that we can categorize it and find it if we need to:
Teaching with CI is a skill and one that takes time to be developed, especially when one has years of non-CI teaching habits to overcome. Your critics may be suffering from the Dunning–Kruger effect. The Dunning–Kruger effect is a cognitive bias in which an unskilled person makes poor decisions and reaches erroneous conclusions, but their incompetence denies them the metacognitive ability to realize their mistakes.
Kruger and Dunning proposed that, for a given skill, unskilled people will:
1. tend to overestimate their own level of skill;
2. fail to recognize genuine skill in others;
3. fail to recognize the extremity of their inadequacy;
4. recognize and acknowledge their own previous lack of skill, if they can be trained to substantially improve.
Nothing worse than the unskilled with an attitude.
