(1999), Journal of Personality and Social Psychology — the foundational study on how incompetence can be paired with unwarranted confidence. Camerer, Loewenstein, and Weber — research on the "curse of knowledge," showing experts systematically underestimate how much explanation others need, especially in their own domain. Klayman & Ha — research on hypothesis-testing behavior, relevant to how people (including intelligent ones) tend to search for confirming rather than disconfirming evidence. Koriat & Bjork — research on the "illusion of comprehension," showing that people who learn information quickly tend to overestimate how deeply they understand it. Cognitive diversity and decision-making — general research area on how diverse teams improve group decision outcomes when input is actually incorporated rather than dismissed. Cognitive dissonance / ego defense mechanisms — foundational work traces back to Leon Festinger's theory of cognitive dissonance (1957), which explains how people resolve conflicts between their self-image and contradictory evidence.
