"Nash equilibrium is a game solution in which none of the players has a self-interested incentive to deviate from its own strategy after considering the counterpart’s choice. In Experiment 1, we used a particular class of game called dominance-solvable. These games contain an option which is better than another one for a player, independently of the action the counterpart will take. We refer to this option as a dominant strategy.3 In Experiment 1, we used two classes of dominance-solvable games characterized by different equilibrium structures, creating sixteen 2x2 games for each class (for a full list of game matrices, see Figure A1 in section A.1, Appendices). The two classes of games (Figure 1) were: (1) dominance solvable “self” games (DSS), in which only the participant had a strictly dominant strategy; (2) dominance solvable “other” games (DSO), in which only the opponent had a strictly dominant strategy."
