In a very special episode, our very own Beth Fisher tells us all about optimism! Beth shares what optimism is, how her recent research shows psilocybin can boost optimism in rats, and what this might mean for humans. We also discuss how optimism shapes our engagement with the world, and if and when it can become too much of a good thing.

How do our identities shift and change over our lifetimes? Dr. Pauline Ho joins us to explore three pathways of identity formation—consolidating, cumulative, and transformative—and how each is shaped by personal histories, social contexts, and important life events. Building off her research with African American college students, Dr. Ho discusses how these pathways could extend to other groups and identities. Beth and Ava chat about meaning-making in their own identities.

The climate crisis demands urgent action, yet many people struggle to make meaningful changes. This week, we’re joined by Dr. Rachit Dubey to hear about the the psychology behind climate inaction. Dr. Dubey shares insights into why humans are wired to seek rewards, leading to consumerism—a core driver of environmental issues. He breaks down how understanding these psychological patterns can help shape more effective climate policies. We learn the best ways to communicate climate change information. Beth and Ava reflect on how their own experiences have influenced their environmental concerns and actions.
