    Dr. Edward Hagen is Professor of Evolutionary Anthropology at Washington State University. His research takes an evolutionary approach to non-infectious diseases, with a focus on mental health.

    In this episode, we talk about Dr. Agustín Fuentes’ book Sex Is a Spectrum, and we discuss whether sex is binary. We start by discussing his main argument, and then talk about the evolution of sex and anisogamy, how to define “male” and “female”, the ratio of males to females, Thomas Laqueur’s account of Western ideas about sex, the use of the terms “3G males” and “3G females”, and the Bateman gradient. We also talk about sexual selection, behavioral sex differences, and the sexual division of labor. We discuss the idea of humans as a biocultural species, and the distinction between sex and gender. We talk about intersex people, trans people, and human rights. We discuss what science would be giving up if it ditched the binary sex concept, and whether the sex binary can be harmful. Finally, we discuss whether the idea that sex is a spectrum is pseudoscience.

Check the website here: http://enlites.com/ Dr. Hanna Schleihauf is Assistant Professor in the Department for Developmental Psychology at Utrecht University. She studies the roots of human diversity: although each of us shares 99.99% of our genes with every other human on the planet, there is massive variation in our socio-cultural practices driven by our ability to learn from and interact with others. Her research investigates socio-cognitive underpinnings of cultural learning, focusing on how cultural novices, children during early and middle childhood, grow into proficient cultural beings. In this episode, we first talk about when and how children start considering other people’s beliefs, the kinds of beliefs people care about, fact-based beliefs and value-based beliefs, and intuitions about people’s control over their own beliefs. We then talk about belief revision and how it develops in children. We discuss what people consider to be good reasoning. Finally, we talk about recent exciting findings that suggest that chimpanzees respond to higher-order evidence.--A HUGE THANK YOU TO MY PATRONS/SUPPORTERS: PER HELGE LARSEN, JERRY MULLER, BERNARDO SEIXAS, ADAM KESSEL, MATTHEW WHITINGBIRD, ARNAUD WOLFF, TIM HOLLOSY, HENRIK AHLENIUS, ROBERT WINDHAGER, RUI INACIO, ZOOP, MARCO NEVES, COLIN HOLBROOK, PHIL KAVANAGH, SAMUEL ANDREEFF, FRANCIS FORDE, TIAGO NUNES, FERGAL CUSSEN, HAL HERZOG, NUNO MACHADO, JONATHAN LEIBRANT, JOÃO LINHARES, STANTON T, SAMUEL CORREA, ERIK HAINES, MARK SMITH, JOÃO EIRA, TOM HUMMEL, SARDUS FRANCE, DAVID SLOAN WILSON, YACILA DEZA-ARAUJO, ROMAIN ROCH, DIEGO LONDOÑO CORREA, YANICK PUNTER, CHARLOTTE BLEASE, NICOLE BARBARO, ADAM HUNT, PAWEL OSTASZEWSKI, NELLEKE BAK, GUY MADISON, GARY G HELLMANN, SAIMA AFZAL, ADRIAN JAEGGI, PAULO TOLENTINO, JOÃO BARBOSA, JULIAN PRICE, HEDIN BRØNNER, DOUGLAS FRY, FRANCA BORTOLOTTI, GABRIEL PONS CORTÈS, URSULA LITZCKE, SCOTT, ZACHARY FISH, TIM DUFFY, SUNNY SMITH, JON WISMAN, WILLIAM BUCKNER, PAUL-GEORGE ARNAUD, LUKE GLOWACKI, GEORGIOS THEOPHANOUS, CHRIS WILLIAMSON, PETER WOLOSZYN, DAVID WILLIAMS, DIOGO COSTA, ALEX CHAU, AMAURI MARTÍNEZ, CORALIE CHEVALLIER, BANGALORE ATHEISTS, LARRY D.

Check the website here: http://enlites.com/ Laura Carroll is a nonfiction author, expert on the childfree choice and pronatalism, and a passionate reproductive rights and ethics advocate. She is the author of The Baby Matrix: Why Freeing Our Minds From Outmoded Thinking About Parenthood & Reproduction Will Create a Better World. In this episode, we talk about childfree choices and pronatalism. We first get into what it is to be childfree, why people morally condemn childfree choices, whether most people without children are “childless by circumstance”, whether people with children are happier, whether we have evolved to want children, and whether people want large families. We also discuss whether we are headed toward “population collapse”, whether aging populations need more babies, the link between pronatalism and eugenics, and whether pronatalism is a threat to women’s reproductive rights.--A HUGE THANK YOU TO MY PATRONS/SUPPORTERS: PER HELGE LARSEN, JERRY MULLER, BERNARDO SEIXAS, ADAM KESSEL, MATTHEW WHITINGBIRD, ARNAUD WOLFF, TIM HOLLOSY, HENRIK AHLENIUS, ROBERT WINDHAGER, RUI INACIO, ZOOP, MARCO NEVES, COLIN HOLBROOK, PHIL KAVANAGH, SAMUEL ANDREEFF, FRANCIS FORDE, TIAGO NUNES, FERGAL CUSSEN, HAL HERZOG, NUNO MACHADO, JONATHAN LEIBRANT, JOÃO LINHARES, STANTON T, SAMUEL CORREA, ERIK HAINES, MARK SMITH, JOÃO EIRA, TOM HUMMEL, SARDUS FRANCE, DAVID SLOAN WILSON, YACILA DEZA-ARAUJO, ROMAIN ROCH, YANICK PUNTER, CHARLOTTE BLEASE, NICOLE BARBARO, ADAM HUNT, PAWEL OSTASZEWSKI, NELLEKE BAK, GUY MADISON, GARY G HELLMANN, SAIMA AFZAL, ADRIAN JAEGGI, PAULO TOLENTINO, JOÃO BARBOSA, JULIAN PRICE, HEDIN BRØNNER, FRANCA BORTOLOTTI, GABRIEL PONS CORTÈS, URSULA LITZCKE, SCOTT, ZACHARY FISH, TIM DUFFY, SUNNY SMITH, JON WISMAN, WILLIAM BUCKNER, LUKE GLOWACKI, GEORGIOS THEOPHANOUS, CHRIS WILLIAMSON, PETER WOLOSZYN, DAVID WILLIAMS, DIOGO COSTA, ALEX CHAU, CORALIE CHEVALLIER, BANGALORE ATHEISTS, LARRY D.
