In this episode, our guest Rory Smead shares insights on spite and what game theory can teach us about this puzzling behaviour. He explains why people sometimes punish others even at a cost to themselves, and whether this can be understood through more than just fairness. Using the ultimatum game as a central example, he discusses how spite can influence decision-making and what this reveals about both human and animal behaviour.

Rory Smead is Professor of Philosophy and the Ronald L. and Linda A. Rossetti Professor for the Humanities at Northeastern University.
