The Nature & Nurture Podcast
Discussing the interaction between Nature (our biology, genes, evolutionary past, and the laws of our universe) and Nurture (our social environments, culture, history, and upbringings), and how these forces impact our lives. New episodes every week with scientists, authors, and bright minds from a wide array of backgrounds.

Nature & Nurture #40: Dr. Randy Thornhill - Parasite-Stress Theory & The Evolution of Conservatism
Dr. Randy Thornhill is an evolutionary biologist and a Distinguished Professor of Biology Emeritus at the University of New Mexico. He is a pioneering researcher of parasite-stress theory, which describes how pathogens have throughout history shaped our behavior and values.
In this episode we discuss parasite-stress theory and the behavioral immune system, and how conservative values are cross-culturally associated with regional parasite prevalence. Additionally, we discuss these findings in the context of the ongoing COVID-19 pandemic, and how advancements in sanitation throughout history may have given rise to more liberal ideals.

Nature & Nurture #38: Dr. Katie Bottenhorn - Neuroinformatics & Women's Health
Dr. Katie Bottenhorn is a neuroscientist and postdoctoral researcher at the University of Southern California. In this episode we talk about Katie's background in neuropsychology, the methodological aspect of neuroinformatics, and Katie's dissertation research focusing on how hormonal fluctuations during the menstrual cycle impact women's brains. Additionally, we discuss gender imbalances in STEM fields such as neuroscience, and compare large sample neuroimaging studies to deep phenotyping approaches featuring a large number of scans within a small sample.

Nature & Nurture #37: Dr. Babak Hemmatian - Natural Language Processing & Political Discourse
Dr. Babak Hemmatian is a cognitive scientist and postdoctoral research fellow at the Beckman Institute of the University of Illinois. His research focuses on using natural language processing techniques to analyze natural discourse, such as social media posts, as they relate to personal and political beliefs. In this episode we discuss Babak's background in computational cognitive science, his PhD research analyzing how Reddit and Twitter users' perspectives on the legalization of gay marriage and marijuana use changed over time, and the ethics of collecting data from social media users.
