Plants, Infants, and the Evolution of Social Learning with Annie Wertz
Annie Wertz, a Professor of Psychology at UCSB, shares her groundbreaking research on infants' understanding of plants and the role of social learning in their interactions. She discusses how babies navigate their environment using social cues to assess which plants are safe or toxic, revealing an intricate cognitive process. Wertz critiques traditional views on cognitive modularity, emphasizing the evolutionary aspects of learning and survival strategies. The conversation highlights the deeper emotional connections humans have with plants and the importance of hands-on learning in fostering positive relationships with nature.

Drugs, Delusions, and Depression with Ed Hagen
Why would a mind ever be delusional or depressed, and can we understand these as functional or maladaptive outcomes? Why do humans take drugs, and why do plants make them in the first place? (And why might the answer to the second question also answer the first?) Join us on a fun, wide-ranging conversation with guest Ed Hagen (Washington State, Vancouver) one of evolutionary psychology’s most encyclopedic minds.

Egalitarianism in the Amazon with Chris Von Rueden
Egalitarianism is not what you think it is! Guest Chris Von Rueden (URichmond) has wrapped his head around what egalitarianism is and shares his insights and what he’s learned living with and studying the Tsimane, hunter horticulturists in the Bolivian rainforest. TL;DR: How to make a more just society requires respecting the complexity of our evolved psychology.

Disgust, Morality, and Kinship with Deb Lieberman
Why do we appeal to disgust when we moralize, and why do we moralize what we find disgusting? Guest Deb Lieberman (UMiami) explains why our human propensity to gang up on others may be driving a lot of our moral sentiments, and why she gets uncomfortable when people appeal to disgust to argue for what is right and wrong.
