    It is not the case that Savage's work formally completed expected utility theory (EUT)

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Savage himself acknowledged his framework applies only to 'small worlds' where all consequences and states are exhaustively enumerable in advance.
      ?

      Think about whether this reason is strong or weak

    • 2.Real decision environments involve genuine Knightian uncertainty where the state space cannot be fully specified, leaving Savage's axioms without grounding.
      ?

      Think about whether this reason is strong or weak

    • 3.A foundational gap in the theory's domain of application constitutes an incompleteness that formal elegance within that domain cannot resolve.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Allais (1953) demonstrated systematic violations of EUT's independence axiom in real human choice, exposing normative incompleteness in Savage's framework.
      ?

      Think about whether this reason is strong or weak

    • 2.A theory that generates predictive failures under controlled conditions cannot be considered formally complete in any epistemically robust sense.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Von Neumann-Morgenstern expected utility theory lacked a rigorous treatment of subjective probabilities
      ?

      Think about whether this reason is strong or weak

    • 2.Savage (1954) showed how to incorporate subjective probabilities and their relationships to preferences over risk within the EUT framework
      ?

      Think about whether this reason is strong or weak
