51 | Why Patriarchy? Foragers, Farmers, and the Origins of Gender Inequality ~ Angarika Deb
Jan 28, 202500:54:39Tap to summarizeWhy are history books so full of men? Why have so many societies treated women as property? In short, why is patriarchy so pervasive? A casual thinker might find an easy answer from biology. Men tend to be bigger and stronger. Hence, they get to run the show. “Just look at chimpanzees!” But this explanation has obvious problems. Indeed, female chimpanzees don’t have much power in their groups. But female bonobos do. And looking at humans, not all human societies are patriarchal — not nearly to the same extent. We don’t need to look at modern Scandinavia to get inspiration for women’s empowerment. Quite the contrary, equality between the sexes might have been the norm throughout most of the human story. This might sound surprising given the rates of patriarchy across time and space. However, it is supported by a simple finding: gender equality is relatively common in existing hunter-gatherers. This stands in stark contrast to their agricultural neighbours. This old finding became part of the scholarly conversation again in late 2024 when a new paper reported high levels of equality between husbands and wives amongst married hunter-gatherers. The levels of equality surprised the scholars themselves. But all this raises an interesting question: why is this? Why would hunting and gathering incline societies towards equality? Or vice versa, why would agriculture nudge societies towards male power? And what should we make of the many outliers from this pattern, like the matriarchal farmers of northeastern India? To discuss these topics, I invited the lead author of the recent paper to the show. Angarika Deb is a cognitive anthropologist, soon to earn her PhD from the Central European University. Despite her young career, she has produced tons of interesting articles on gender inequality around the world. A wide-ranging conversation was guaranteed.

Transcribe →Bonus | Evolution Beyond the Selfish Gene (with Eva Jablonka)
Jan 16, 202500:19:30Tap to summarize“We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes.” - Richard Dawkins in The Selfish Gene In 1976, Richard Dawkins published one of the most iconic science books of all time. It has inspired a generation of science enthusiasts. But unsurprisingly, many readers disliked the idea of being but a “robot vehicle” or a “survival machine” for some tiny molecules — especially if these molecules are best served by repeated pregnancies or donations to a sperm bank. Yet Dawkins was right on one thing: “however much we may deplore something, it does not stop being true.” So what is true? I have previously written about one claim in the Selfish Gene which is certainly not true. This is the claim that, if we accept the book's biological theories, then we humans must be “born selfish”. Even Dawkins has accepted that this was a "rogue" claim that readers should "mentally delete". You can hear more by heading to episode 20 of On Humans. But what about the underlying science? Are selfish genes still the right way to think about the facts of evolution? Not so, according to Eva Jablonka. You might remember Jablonka from episode 36 on the evolution of consciousness. But before her work on consciousness, Jablonka was famous for her research on epigenetic inheritance -- literally, "inheritance beyond the gene". So what is epigenetic inheritance? What do we know about it scientifically? And does it matter philosophically? I hope you enjoy this conversation.

Transcribe →Bonus | The Real Lessons From The World Happiness Report (with Lara Aknin)
Jan 9, 202500:16:26Tap to summarizeEach year, the World Happiness Report ranks countries based on their citizen's life satisfaction. My home country, Finland, tends to come at the top. Sure. But lessons can we draw from all this? Beyond patting Finns on the back, can we distil some more insights from the report?I got to discuss this with Lara Aknin, co-editor of the World Happiness Report. In this previously unpublished clip, Aknin explains the major findings from the World Happiness Report and reveals the “single best predictor of happiness” across countries.

Transcribe →Bonus | Some Myths About Human Mating (with Katie Starkweather)
Jan 5, 202500:11:57Tap to summarizeMany traditional societies accept polygyny (one man, many wives). Monogamy, too, is practised across the globe. But what about polyandry — one woman, many husbands? Is this a "dubious idea" as sometimes suggested by evolutionary theorists? In this bonus clip, anthropologist Katie Starkweather offers interesting examples of formal and informal polyandry from around the world. She also brings nuance to theories about jealousy in men and women. (This is a previously unpublished clip from my conversation with anthropologist Katie Starkweather, as published in episode 43.)

Transcribe →Encore | The Mindbending Conversation That Topped 2024 (with Donald Hoffman)
Dec 31, 202401:28:37Tap to summarizeHappy New Year 2025! To celebrate, here is an encore of what proved to be the most popular episode of 2024. This rerun combines episodes 30 and 31 into one epic journey towards the frontiers of human understanding. My guest is Donald Hoffman. Our topics are consciousness, cosmos, and the meaning of life. Enjoy! Original show notes Laws of physics govern the world. They explain the movements of planets, oceans, and cells in our bodies. But can they ever explain the feelings and meanings of our mental lives? This problem, called the hard problem of consciousness, runs very deep. No satisfactory explanation exists. But many think that there must, in principle, be an explanation. A minority of thinkers disagree. According to these thinkers, we will never be able to explain mind in terms of matter. We will, instead, explain matter in terms of mind. I explored this position in some detail in episode 17. But hold on, you might say. Is this not contradicted by the success of natural sciences? How could a mind-first philosophy ever explain the success of particle physics? Or more generally, wouldn't any scientist laugh at the idea that mind is more fundamental than matter? No — not all of them laugh. Some take it very seriously. Donald Hoffman is one such scientist. Originally working with computer vision at MIT's famous Artificial Intelligence Lab, Hoffman started asking a simple question: What does it mean to "see" the world? His answer begins from a simple idea: perception simplifies the world – a lot. But what is the real world like? What is “there” before our perception simplifies the world? Nothing familiar, Hoffman claims. No matter. No objects. Not even a three-dimensional space. And no time. There is just consciousness. This is a wild idea. But it is a surprisingly precise idea. It is so precise, in fact, that Hoffman’s team can derive basic findings in particle physics from their theory. A fascinating conversation was guaranteed. I hope you enjoy it.

Transcribe →Live from London | Yasheng Huang on the Origins of Modern China
Dec 23, 202401:25:51Tap to summarizeThis was fun! Last Wednesday saw the first-ever live recording of On Humans. The event was held at the London Business School, courtesy of the LBS's China Club. My guest was MIT Professor Yasheng Huang, familiar to regular listeners from the China trilogy published earlier this fall. In this new episode, we keep tackling the origins of modern China. This time, we draw insights from Huang's two upcoming books: Revisiting the Needham Question and Statism With Chinese Characteristics. The conversation is structured around five themes: 1) the "Needham Question"; 2) Keju exams; 3) Scale; 4) Scope; and 5) The Eighties. Expect juicy insights to questions such as: Why was more Buddhism linked to more inventions in ancient China? How does footbinding relate to China's technological decline? Has China's GDP growth stopped serving Chinese workers? Towards the end of the conversation, Huang also shared his memories of working in China through the 1989 crackdown at Tiananmen Square.

Transcribe →50 | A New Theory on the Broadest Patterns of History ~ Ideen Ali Riahi
Dec 2, 202401:08:29Tap to summarizePersians. Romans. Chinese. Guptas. Abbasids. Mongols. British. The list of the world’s largest empires is a list of different peoples of Eurasia. With the sole exception of ancient Egypt, the Eurasian landmass has been the breeding ground for the largest empire of each moment in history. Why has Eurasia been so prone to large empires? Similarly, why did so many technological breakthroughs — from writing to gunpowder — occur in Eurasia? And how did these broader patterns of Eurasian history enable the dark chapters of European colonialism? These questions constitute some of the “broadest patterns of history”, to quote Jared Diamond’s Guns, Germs, and Steel. Indeed, these are not only the broad contours of the last few millennia: searching for answers, we need to dig deep into the origins of agriculture and beyond. My guest today, Ideen Ali Riahi, has been digging very deep indeed. Building on Diamond’s original project, Riahi has traced the deepest roots behind Eurasia’s outsized power in human history. And if he is correct, these roots extend to periods way before the dawn of agriculture. In this episode, we discuss topics such as: The “Why Eurasia?” questions: What does it mean? What answers do we have? And is this a meaningful question to start with? Environmental determinism vs environmental realism Did the activities of our Ice Age ancestors prepare Eurasian lands for farms, cows, and cavalries? Riahi’s case against genetic explanations of Eurasian dominance and Europe’s rise As always, we finish with my guest’s reflections on humanity.

49 | Is War Inevitable? Lessons from East Asia ~ David C. Kang
Nov 15, 202400:51:21Tap to summarizeWhy do wars begin? How can we avoid them? Do countries wage wars whenever it suits their own goals? Or are wars a product of failed understanding and military madmen? These are questions at the centre of the study of war and peace. But for too long, the field of international relations has answered them by scavenging data from European history alone. To better understand the human capacity for peace, we need to understand military history more broadly. Or so argues David C. Kang, a professor of global politics at the University of Southern California. A Korean American scholar, Kang argues that the histories of China, Japan, Korea, and Vietnam give us lessons that no reading of European countries could: lessons about neighbouring countries living in peace for centuries. Yes, there was violence. At times, there was war. But peace between these countries prevailed for stunningly long periods. And contrary to standard theories of war and peace, this wasn’t achieved by a “balance of powers” nor by the threat of a common enemy. But is this too peaceful a picture of East Asian history? Didn’t China keep up bullying Vietnam? What about the epic wars started by Japan? What about the Mongols, the Great Wall, and China’s expansion on its Western frontier? And what, if anything, can this tell about war and peace in the 21st Century? Doesn’t the “Thucydides trap” make a war between the US and China inevitable? We discuss these and many other questions in this fascinating episode. I am particularly glad to bring you this episode as it brings together two of the major themes on the show this fall: the study of war and peace and the study of Asian history. Co-hosting again is Jordan Schneider from ChinaTalk. Check out also our “What About China” trilogy from September (episodes #44-46)!

Transcribe →48 | Is War Natural After All? Revisiting the Debate ~ Luke Glowacki
Nov 2, 202401:06:04Tap to summarizeOur ancestors did not wage war. Warfare emerged only when humans started settling down and storing food. Indeed, some modern hunter-gatherers still enjoy the peaceful existence that once was the natural state of our species. Or so argued Douglas P. Fry, my guest in episode 8. I found many of his arguments convincing. For example, ancient cave art is surprisingly void of depictions of warfare. You can hear many more of his arguments in that episode, titled "Is War Natural For Humans?" But not all scholars agree. Far from it. And I owe a voice to the other side of the debate. So here is an episode with one of the most thoughtful voices arguing for a deeper origins of war. Luke Glowacki is a professor of anthropology at Boston University, where teaches courses on the evolution of war. And he believes that war has very ancient origins, indeed. We had a very stimulating conversation, discussing topics such as: (03:00) The debate: What can we all agree on? And what are the disagreements? (12:10) Hunter-gatherers: Are they peaceful? And are they any good as models of the past? (25:55) Archaeology: Cave paintings and broken bones (34:55) Primatology: Chimpanzees and bonobos (46:40) Implications: What can we learn from all this? As always, we finish with my guest's reflections on humanity. LINKS Head here for links to relevant academic articles -- and the video of the chimpanzee raid!
