Subjective game structures: eliciting alternatives and payoffs to study the properties of social interactions

The present study transforms subjective conflict perceptions into formally defined games, tests the reliability of the transformation, and explores the properties of several conflict scenarios. To this end we: (i) develop an illustration-based method that transforms implicit perceptions of expected outcomes and experiences into sets of structured numerical values, termed subjective game structures; (ii) develop a reliability index that compares the properties of two subjective games, allowing to test the consistency of repeatedly elicited games; (iii) empirically test game perceptions across eight conflict scenarios; and (iv) interpret the results in terms of two game taxonomies. The results reveal the capacity of the applied methods to transform vague social scenarios into reliable formal games, point to natural solutions, and show the distribution of games that characterizes each conflict scenario. The newly developed model and tools provide a potent instrument for studying a diverse array of social interactions, ranging from interpersonal relations to trade, political conflicts, and war. They represent invaluable resources for conducting polls, examining implicit attitudes, and assisting in the formulation of political, commercial, and social policies.
