Marginalia Episodes are in collaboration with Marginalia Science! Marginalia Science is a community committed to promoting the work of scholars who are traditionally underrepresented in academia. In each Marginalia Episode, we feature a guest who has been featured in the Marginalia Science Monthly Newsletter.

In this re-air episode from 2025, Enna chats with Professor Erica Bailey at UC Berkeley Haas School of Business. Erica broadly studies the construct of authenticity, asking questions like, how do we know who we are? When do we feel the most like ourselves? Why do we often fail, despite our best efforts, to share our inner world with others? In this episode, we discuss her recent paper on how self-perceptions influence subjective authenticity. To learn more about Erica, you can read the Marginalia Science Newsletter below.

Adani chats with Tamar Kushnir, Professor of Psychology and Neuroscience at Duke University. Tamar’s research spans pretty much everything you can imagine: Cognitive development, causal learning, social cognition, moral cognition, cultural psychology, free will, imagination, counterfactual thinking, self-control, and more! In this conversation, we discuss Tamar’s fascinating review on imagination and social cognition in childhood alongside many fun tangents about superheroes, the Wright Brothers, and collective social change. Tamar also shares what she most enjoys about research in the first place, and what she’s excited for next!

In this re-air episode from 2022, Eric chats with Robin Dunbar, Emeritus Professor of Evolutionary Psychology at Oxford. Robin has famously studied the evolution of the human brain, arguing that our brain developed to understand the complex social world we have created for ourselves. Most know him for “Dunbar’s number,” or the limit to the number of individuals we can maintain stable relationships with. Robin has received more awards than could be counted, including the prestigious Huxley Memorial Medal. He has written various books, most relevant for this conversation a book called “Friends: Understanding the Power of our Most Important Relationship.”

In this wide-ranging episode, Eric and Robin discuss why Dunbar’s number is actually a whole series of numbers. Robin explains how he arrived at this number, why it is so relevant to everything from our globalized world and big cities to maintaining friendships. Do psychopaths need friends to be happy? If you don’t like people, should you move into the woods and never talk to anyone again? He explains why we gossip and what makes something funny. Finally, he shares some personal stories about his career and why his discovery of Dunbar’s number was actually an accident.

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..

Su chats with Dr. Roger Levy. Dr. Levy is a Professor in the Department of Brain and Cognitive Sciences at MIT, where he directs the Computational Psycholinguistics Laboratory. His research focuses on theoretical and applied questions in the processing and acquisition of natural language. His work furthers our understanding of the cognitive underpinning of language processing and acquisition, combining computational modeling, psycholinguistic experimentation, and analysis of large, naturalistic language datasets, to help design models and algorithms that will allow machines to process human language. In today's episode, we discuss his research background together with his recent work "The Science of Language in the Era of Generative AI".
