    Part of a larger discussion

    Supports→Deleting weakly dominated strategies just like strictly dominated strategies has odd consequences

    Weak dominance lacks the epistemic robustness of strict dominance: a weakly dominated strategy remains rational under at least one opponent belief.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Strict dominance guarantees optimality regardless of opponent beliefs, while weak dominance requires specific belief assumptions to justify play.
      ?

      Think about whether this reason is strong or weak

    • 2.Rational agents should prefer strategies that perform well under uncertainty. Strictly dominated strategies fail this test; weakly dominated strategies pass it sometimes.
      ?

      Think about whether this reason is strong or weak

    • 3.Epistemic robustness means a strategy remains rational across wider ranges of belief assignments. Strict dominance satisfies this; weak dominance does not.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.The distinction between strict and weak dominance is pragmatically irrelevant: both require eliminating strategies that could harm rational players under plausible beliefs.
      ?

      Think about whether this reason is strong or weak

    • 2.Epistemic robustness is not the only criterion for rationality. A weakly dominated strategy can be epistemically justified if the opponent belief is well-founded through credible information.
      ?

      Think about whether this reason is strong or weak

    • 3.Real strategic situations rarely feature perfectly uniform belief distributions. Weak dominance reflects realistic constraints better than strict dominance does.
