On the overconfidence effect, Martin Hilbert argues that confidence bias can be explained by a noisy conversion of objective evidence into subjective estimates, where noise is defined as the mixing of memories during the observing and remembering process. [44]
One of the main effects of illusory superiority in IQ is the "Downing effect". This describes the tendency of people with a below-average IQ to overestimate their IQ, and of people with an above-average IQ to underestimate their IQ (similar trend to the Dunning-Kruger effect ).

Terms and concepts include coherence, attention, laziness, association, jumping to conclusions, WYSIATI (What you see is all there is), and how one forms judgments. The System 1 vs. System 2 debate includes the reasoning or lack thereof for human decision making, with big implications for many areas including law and market research.
