  1. Arguing in a Social Context Iyad Rahwan

  2. Introduction Argument takes place in a social context • Arguing with oneself vs. arguing with others New challenges: • How does the audience evaluate arguments? • How do arguers strategize? Opportunities for cross-disciplinary work: • Experimental psychology • Game theory

  3. The Psychology of Argument Evaluation

(in press) H1: Defeat lowers confidence in A’s conclusion H2: Reinstatement increases confidence in A H3: Reinstatement fully restores confidence in A’s conclusion H4: Reinstatement is due to successfully defeating B (rather than supporting C)

  5. Floating Reinstatement I. Rahwan, M. I. Madakkatel, J. F. Bonnefon, R. N. Awan and S. Abdallah. Behavioural Experiments for Assessing the Abstract Argumentation Semantics of Reinstatement.
