Aug 26, 2025 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.

Episode notes
Understanding Requires Iterative Learning
- Mastering evolutionary psychology requires deep, iterative learning; initial 'aha' moments often crumble with deeper reading.
- True understanding needs sustained study, discussion, and application, not superficial reading.
Processing Creates Dependence On Culture
- Human diets are broad and often require processing to render plant staples edible, which increases reliance on cultural transmission.
- Models show social learning is favored over deadly personal trial-and-error for acquiring plant-use knowledge.
Tight Generalization Protects Against Toxic Errors
- Babies generalize edibility information tightly for plants and attend to fine-grained features when categorizing them.
- Tight generalization reduces fatal errors between visually similar edible and toxic species.
