    Reasons Against

    Reason against 1 of 2
    ?
    • 1.Classical game theory already incorporates individual rationality assumptions through Nash equilibrium's mutual best-response conditions.
      ?

      Think about whether this reason is strong or weak

    • 2.The bottom-up/top-down distinction collapses when both approaches ultimately require common knowledge of rationality to generate predictions.
      ?

      Think about whether this reason is strong or weak

    • 3.Aumann's foundational work on correlated equilibrium shows epistemic and classical approaches converge on equivalent solution concepts.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.The epistemic approach inherits classical game theory's idealized rationality constraints, making 'bottom-up' a redescription rather than a genuine methodological departure.
      ?

      Think about whether this reason is strong or weak

    • 2.Bounded rationality theorists like Herbert Simon argue that any framework preserving perfect Bayesian updating fails to model actual individual decision-making from the ground up.
      ?

      Think about whether this reason is strong or weak

    The epistemic approach to game theory focuses on the choices of individual decision makers in specific informational contexts, assessed on the basis of decision-theoretic choice rules. This is a bottom-up, as opposed to the classical top-down, approach. Early work in this paradigm include Bernheim (1984) and Pearce’s (1984) notion of rationalizability and Aumann’s derivation of correlated equilibrium from the minimal assumption that the players are “Bayesian rational” (Aumann 1987).
