Explanatory Depth

People feel they understand complex phenomena with far greater
precision, coherence, and depth than they really do; they are subject
to an illusion; an illusion of explanatory depth. The illusion is far
stronger for explanatory knowledge than many other kinds of
knowledge, such as that for facts, procedures or narratives. The
illusion for explanatory knowledge is most robust where the
environment supports real-time explanations with visible mechanisms.
We demonstrate the illusion of depth with explanatory knowledge in
Studies 1-6. Then we show differences in overconfidence about
knowledge across different knowledge domains in Studies 7-10.
Finally, we explore the mechanisms behind the initial confidence and
behind overconfidence in Studies 11 and 12. Implications for the
roles of intuitive theories in models of concepts and cognition are
