Phrase: Knightian uncertainty | Statement: [Frank H. Knight, hasConcept, Knightian uncertainty]

Target entity: Knightian uncertainty
Context triple: [Frank H. Knight, hasConcept, Knightian uncertainty]

• A. Ellsberg paradox
  The Ellsberg paradox is a famous problem in decision theory and economics that demonstrates how people’s choices often violate expected utility theory due to ambiguity aversion.
• B. Risk, Ambiguity and the Savage Axioms
  "Risk, Ambiguity and the Savage Axioms" is a seminal 1961 paper by Daniel Ellsberg that challenges expected utility theory by demonstrating how people systematically prefer known risks over ambiguous ones, a phenomenon now known as the Ellsberg paradox.
• C. Ellsberg
  Ellsberg is a surname most famously associated with Daniel Ellsberg, the American military analyst who leaked the Pentagon Papers during the Vietnam War.
• D. St. Petersburg paradox
  The St. Petersburg paradox is a famous problem in probability theory and economics that highlights how a lottery with an infinite expected payoff can still attract only a finite price from rational gamblers, challenging traditional notions of expected value and decision-making under risk.
• E. Allais paradox
  The Allais paradox is a famous decision-making puzzle in behavioral economics that shows how people's choices under risk often violate the expected utility theory, revealing systematic inconsistencies in rational choice models.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Knightian uncertainty
Triple: [Frank H. Knight, hasConcept, Knightian uncertainty]

Knightian uncertainty is an economic concept describing situations where the probability of outcomes is fundamentally unknowable or unquantifiable, going beyond measurable risk.
