    Part of a larger discussion

    Challenges→The fourth Nash Equilibrium (R, r2, r3) arises because Player III's entire information set is off the path of play when Player I plays R and Player II plays r2, making Player III's action inconsequential to the outcome.

    Consequential irrelevance in a single play does not establish strategic irrelevance: Selten's (1975) trembling-hand perfection requires strategies to be best responses even against small perturbations that reach off-path nodes.

    Key Terms

    Consequential irrelevance(as a condition that doesn't guarantee strategic irrelevance)
    Something that doesn't affect the outcome in a single instance or moment.
    Off-path nodes(as scenarios that might arise from mistakes or unexpected events)
    Situations or decision points in a game that wouldn't normally occur if everyone played perfectly according to plan.
    Perturbations(as deviations from perfect play)
    Small, random disturbances or deviations from the expected behavior; in this case, tiny mistakes or unexpected moves.
    Reinhard Selten(as the originator of the concept being discussed)
    A German economist and game theorist who won the Nobel Prize for his work on how people make strategic decisions in competitive situations.

    (as the conclusion being tested)
    A situation where something doesn't matter for determining the best long-term plan or approach to winning.
    Trembling-hand perfection(as the main concept in the statement)
    A solution concept in game theory that tests whether a strategy remains a good choice even if players occasionally make small mistakes or random errors.
    best response(Implicit in the definition of strict domination)
    A strategy s_i is a best response with respect to a probability measure p over opponent strategies if it maximizes the player's expected utility given p.
