CORE DEFINITION

Proposed by Nassim Taleb. Refers to elites who are well-educated academically and skilled in theoretical reasoning, but lack common sense about real life, have no 'skin in the game' (do not bear the consequences of their decisions), and often make foolish judgments detached from reality.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Beware of empty theorizing. It reminds us that academic credentials and IQ do not equal wisdom. When listening to expert advice, examine whether they have practical experience, whether they take risks, and whether they possess common sense.

Anchor fast decisions

'Intellectual Yet Idiot' is a colloquial term referring to someone who scores high on intelligence tests or excels in bookish or logical abilities, yet is clumsy in common sense, interpersonal skills, or real-world judgment. It reminds us that 'intelligence' is not the same as 'wisdom/competence'.
