    It is not the case that Common knowledge of rationality is satisfiable by any model where each player's strategy is a best response given their actual beliefs, without requiring caution.

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

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.If players hold heterogeneous or false beliefs about others' rationality, coordination failures and welfare losses emerge that undermine mutual optimization claims.
      ?

      Think about whether this reason is strong or weak

    • 2.Without common knowledge assumptions, there's no guarantee that each agent's beliefs about others' beliefs align, creating vulnerability to exploitation or strategic instability.
      ?

      Think about whether this reason is strong or weak

    • 3.Best-response logic presupposes stable expectations; without shared understanding that all players are rational, beliefs can cascade unpredictably across strategic reasoning levels.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Rationality requires only that agents maximize utility given their beliefs, not that they hold particular beliefs about others' rationality.
      ?

      Think about whether this reason is strong or weak

    • 2.Common knowledge of rationality is unnecessarily restrictive; best-response play occurs whenever each agent's strategy optimizes their payoff given actual expectations.
      ?

      Think about whether this reason is strong or weak

    • 3.Caution (conservative play) is a choice some rational agents might reject; rationality permits risk-taking given sufficiently optimistic but reasonable beliefs.
      ?

      Think about whether this reason is strong or weak
