Discussing the nature of our universe, our biology, our environment, 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 #36: Dr. David Geary - The Evolution of Human Sex Differences
Dr. David Geary is a cognitive developmental and evolutionary psychologist and Curators' Distinguished Professor and a Thomas Jefferson Fellow at the University of Missouri. He is an expert in children's mathematical development and the evolution of human sex differences.
Nature & Nurture #35: Dr. Mark Schaller - The Behavioral Immune System
Dr. Mark Schaller is a Professor of Psychology at the University of British Columbia and one of the pioneering researchers of the behavioral immune system.
Nature & Nurture #34: Dr. Rosalind Arden - Intelligence in Humans & Dogs
Dr. Rosalind Arden is a behavioral geneticist, Research Fellow at the London School of Economics, and an expert in the study of intelligence. In this episode we discuss the genetic and environmental factors that influence human intelligence, and Rosalind's pioneering work studying intelligence in dogs.
Nature & Nurture #33: Dr. Arik Kershenbaum - The Zoologist's Guide to the Galaxy
Dr. Arik Kershenbaum is an evolutionary biologist and lecturer at the University of Cambridge with expertise in studying animal communication. In this episode we discuss his book, The Zoologist's Guide to the Galaxy, and the many universal features of evolution and communication that we might expect to find in alien life.
Nature & Nurture #32: Dr. Julia Marshall - The Development of Cooperation
Dr. Julia Marshall is a postdoctoral researcher at Boston College, where she studies children's cooperative development, moral development, and desire to punish. In this episode we discuss Julia's background in psychology, how moral values can be studied empirically in children, the developmental factors that lead to the desire to punish and cooperate, and compare children's and adults' prosocial norms.

Nature & Nurture #31: Dr. Ryan Boyd - Natural Language Processing, Personality, & Behavior
Dr. Ryan Boyd is a computational social and behavioral scientist at Lancaster University. In this episode, we discuss Ryan's background in psychology, his transition from experimental to computational psychology, and his exposure to natural language processing. Additionally, we discuss how natural language processing research can be used to analyze text and predict personality, behavior, and authorship. Finally, we discuss the ethics of data collection on social media, and forms of data science that may be used to protect privacy.
