166 - Steve Rathje: The Psychology of Virality

Su chats with Dr. Steve Rathje. Dr. Rathje is an incoming Assistant Professor of Human-Computer Interaction in the School of Computer Science at Carnegie Mellon University. He is an NSF and AXA postdoctoral fellow at New York University. Steve’s work centers on the psychology of technology. He studies how core psychological phenomena like polarization, intergroup conflict, the spread of information, and mental health interact with emerging technologies such as artificial intelligence and social media. Through a combination of behavioral science, computational methods, and large-scale data, his research sheds light on how our minds and our societies are being shaped in the digital age. In today's episode, we discuss his research background together with his recent review paper “The psychology of virality," in which they explore why certain content spreads rapidly online and offline, often involving a mix of emotional, social, and structural factors..
