Raihan Alam is a third year PhD student in Management and National Science Foundation Graduate Research Fellow. He researches the causes and consequences of moral disagreement, with applications to criminal justice, extremism, and political polarization. In his recent work, he has found that incentivizing punishment can destabilize cooperation with anonymous strangers, that punishment of morally agreeable acts erodes the legitimacy of punishers and receptivity to punishment, and that stock trading by members of Congress diminishes citizens’ willingness to comply with the law. Moving forward, he is examining the role of moralistic anger in motivating political action and how it relates to emotion-regulation and meaning in life. His interest in CARTA lies in understanding the evolution of large-scale cooperation in humans.
