Unidimensional Scaling of Two Person Non-Zero Sum Games.
Baerwaldt, James; Talley, Martha
Groups of students were required to respond to the same eight two-person games, two variants each of four qualitatively different separable games including Prisoner's Dilemma. The games were generated by varying a payoff parameter which altered the potential maximum per trial difference between payoffs for the two players. The groups differed systematically in terms of the types of numerical representations chosen for each game. For each pair of games, the subjects were asked to indicate which strategy for each game they would choose to play against a hypothetical opponent and for which of the two games they would most prefer to play the dominant strategy. The paired-comparison data for each subject was entered into a dominance matrix and processed by triangular analysis. The data from 33 of the 35 subjects yielded satisfactory unidimensional scales. It was concluded that it is possible to scale qualitatively different games along the same dimension. It was further concluded that most game players prefer to select strategies which will maximize the difference between their score and their opponent's score even when those strategies are not dominant.
