- According to evolutionary economics, which postulates the bounded rationality of agents, economic behaviors can evolve by exposing the agents to a certain condition repeatedly. Theoretical studies modeled on the reciprocity-based iterated prisoner’s dilemma game (IPD) showed that choosing the cooperative choice is the economic behavior in this game. Several experimental studies of non-human vertebrates have endorsed this theory by verifying the dominance of the cooperative choice over defecting choices in the animal’s behavior in the IPD. However, the instability of the choice rate suggested that the homeostasis-based reinforcer, i.e., food or drink, provokes in the animal both the motivation to play the game and the impulsivity to satisfy the physiological needs, leading to an irrational choice.
Here, we show the mouse having advantage in genetic studies can evolve the stable cooperative behavior in the game when they are motivated by the wireless intracranial self stimulation, which is grounded on pure incentive mechanism independent of satiation.
