We conduct an experimental study on behavior and underlying cognition in prisoner’s
dilemmas with/without role-switching from the viewpoint of inductive game
theory. Subjects start with no knowledge about his and the other’s payoffs, and
learn them through repeated play. In cases with no role-switching, a large proportion
of subjects adopt a dominant strategy. In the cases with role-switching, where
the subjects alternate positions (row and column players), the prediction by inductive
game theory that they will choose the pair of actions maximizing the simple
sum of payoffs is observed for various pairs. We study their behaviors and cognitions
from various different viewpoints. The study suggests a strong implication
about certain foundational assumptions of inductive game theory: In particular,
statistical hypothesis tests are not only used to analyze the experimental data but
also play more positive roles for inductive game theory.
