This conversation occurred just after President Trump withdrew US forces from Northern Syria. Steve, Corey and Sebastian debate ISIS and the Kurds. Sebastian argues that men who went to war after 9/11 wanted to experience communal masculinity, as their fathers and grandfathers had in Vietnam and WWII, a tradition dating back millennia. When they came home, they faced the isolation of affluent contemporary American society, leading to high rates of addiction, depression, and suicide. War veterans in less developed countries may be psychologically better off, supported by a more traditional social fabric.ResourcesTranscriptSebastian JungerTribe: On Homecoming and Belonging (Book)War (Book)Hell on Earth (Trailer)Restrepo (Trailer)Manifold: David Skrbina on Ted Kaczynski, Technological Slavery, and the Future of Our Species – #7

MSU Psychology Professor Zach Hambrick joins Corey and Steve to discuss general cognitive ability, the science of personnel selection, and research on the development of skills and expertise. Is IQ really the single best predictor of job performance? Corey questions whether g is the best predictor across all fields and whether its utility declines at a certain skill level. What does the experience of the US military tell us about talent selection? Is the 10,000 hour rule for skill development valid? What happened to the guy who tried to make himself into a professional golfer through 10,000 hours of golf practice?ResourcesTranscriptScience of ExpertiseZach Hambrick (Faculty Profile)Armed Services Vocational Aptitude BatteryProject 100,000 (1960s DoD Program)Test Validity Study Report (CLA)The Validity and Utility of Selection Methods in Personnel Psychology

Steve and Corey talk to Andrew about his new introduction to his book “The War for the Soul of America.”  While the left largely won the culture wars, the three wonder whether the pendulum has swung so far left that many liberals are alienated by today’s cultural norms.Other topics: Was the left’s victory in the debate over the college curriculum pyrrhic? Is identity politics a necessary step in liberation or a problematic slide toward greater division or both? Are current students too sensitive, and easily triggered, to take the fight to the Billionaire class? ResourcesTranscriptAndrew Hartman (Faculty Profile)A War for the Soul of America: A History of the Culture Wars[BONUS] – Left and Right at MSU – #27.5

Steve and Corey talk to Ted about his article for the August issue of Harper’s Magazine, “The Last Frontier”. Ted describes how Trump’s election led him to seek out his new project on people living off the grid in Colorado’s San Luis Valley (“Appalachia without the Trees”). The three discuss how immigration has changed since he wrote Coyotes in 1987. Ted explains how working as a prison guard in Sing Sing led to the uncomfortable realization that he was getting comfortable with unnecessary violence and offers advice to young people seeking to write interesting stories in the new media landscape.ResourcesTranscriptTed ConoverThe Last Frontier: Homesteaders on the margins of AmericaCoyotes: A Journey Through the Secret World of America’s Illegal AliensNewjack: Guarding Sing SingRolling Nowhere: Riding the Rails with America’s Hoboes

Steve and Corey talk to Jason about a fundamental question of neuroscience: Do humans grow new neurons as adults? The dogma that humans do not, gave way to the dogma that they do, which is now being questioned. Adult neurogenesis has been associated with learning, better cognitive function and resistance to depression. Jason suggests that a simple error of treating young mice as models for adult humans led to excessive optimism regarding the potential for later neuronal growth. Recent findings suggest that adults grow few, if any, new neurons but that what little neurogenesis occurs can probably be enhanced by exercise.ResourcesTranscriptThe Synder LabWarren Sturgis McCulloch Interview (1969)

Steve and Corey talk to Tim Searchinger about the unintended consequences of biofuels policies. Searchinger argues that these policies do not consider the opportunity costs of using plants for fuel rather than food. Combined with crazy carbon accounting principles, existing rules make cutting down trees in the US, shipping them to Europe and burning them in power plants count as carbon neutral under the Kyoto protocol. The three also discuss how eating less beef in the developed world along with educating women, family planning, and reducing child mortality in the developing world can decrease stress on land use and emissions.ResourcesTranscriptCreating a Sustainable Food Future: A Menu of Solutions to Feed Nearly 10 Billion People by 2050Timothy Searchinger

Jamie Metzl joins Corey and Steve to discuss his new book, Hacking Darwin. They discuss detailed predictions for the progress in genomic technology, particularly in human reproduction, over the coming decade: genetic screening of embryos will become commonplace, gene-editing may become practical and more widely accepted, stem cell technology may allow creation of unlimited numbers of eggs and embryos. Metzl is a Technology Futurist, Geopolitics Expert, and Sci-Fi Novelist. He was appointed to the World Health Organization expert advisory committee governance and oversight of human genome editing. Jamie previously served in the U.S. National Security Council, State Department, Senate Foreign Relations Committee and as a Human Rights Officer for the United Nations in Cambodia. He holds a Ph.D. in Southeast Asian history from Oxford University and a J.D. from Harvard Law School.ResourcesTranscriptHacking Darwin: Genetic Engineering and the Future of HumanityJamie Metzl’s Personal Website

Polymath and economist Tyler Cowen (Holbert L. Harris Professor at GMU) joins Steve and Corey for a wide-ranging discussion. Are books just for advertising? Have blogs peaked? Are podcasts the future or just a bubble? Is technological change slowing? Is there less political correctness in China than the US? Tyler’s new book, an apologia for big business, inspires a discussion of CEO pay and changing public attitudes toward socialism. They investigate connections between populism, stagnant wage growth, income inequality and immigration. Finally, they discuss the future global order and trajectories of the US, EU, China, and Russia.ResourcesTranscriptPersonal WebsiteMarginal Revolution [Blog]Conversations with Tyler [Podcast]Tyler Cowen | Bloomberg Opinion ColumnistBig Business: A Love Letter to an American Anti-Hero

Steve and Corey talk to Betsy McKay, senior writer on U.S. and global public health at The Wall Street Journal, about her recent articles on heart disease. Betsy describes how background reporting led to her article linking the recent drop in life expectancy in the United States, often attributed to the opioid crisis or increases in middle age suicides due to economic despair, to the increasing prevalence of heart disease, driven by the rise in obesity. The three also discuss current public health recommendations on how to reduce heart disease risk and on the use of calcium scans to assess arterial plaque buildup. Steve describes boutique medical programs available to the super-rich that include full body scans to search for early signs of disease. Betsy elaborates on how she approached reporting on a new study linking egg consumption to higher cholesterol and increased risk of death, a result at odds with other recent findings and national recommendations that two eggs a day eggs is safe and healthy.

Steve and Corey speak with Ted Chiang about his recent story collection “Exhalation” and his inaugural essay for the New York Times series, Op-Eds from the Future. Chiang has won Nebula and Hugo awards for his widely influential science fiction writing. His short story “Story of Your Life,” was the basis of the film Arrival (2016). Their discussion explores the scientific and philosophical ideas in Ted’s work, including whether free will is possible, and implications of AI, neuroscience, and time travel. Ted explains why his skepticism about whether the US is truly a meritocracy leads him to believe that the government-funded genetic modification he envisages in his Op-Ed would not solve the problem of inequality.ResourcesExhalation by Ted ChiangStories of Your Life and Others by Ted ChiangTed Chiang’s New York Times Op-Ed From the FutureTranscript

Dr. Rebecca Campbell is a Professor of Psychology at Michigan State University, whose research focuses on violence against women and children with an emphasis on sexual assault. Steve and Corey discuss her recent National Institute of Justice-funded project to study Detroit’s untested rape kits. Dr. Campbell describes the problem of untested kits and her work with police departments around the country to reduce the backlog. She explains how the use of the national CODIS database has led to sharply higher estimates of the proportion of rapes committed by serial perpetrators and how many rapists appear to be criminal “generalists”, committing a wide range of offenses. She describes the dynamics of sexual assault investigations, the factors that lead police to put more effort into investigating certain cases over others, and how common ways of questioning women can lead them to disengage from the process. Other topics include the incentives at work in law enforcement, the slow pace at which new research in DNA t

Steve and Corey talk with Mark Moffett, Photographer and Research Fellow at the Smithsonian Institute, about his new book The Human Swarm: How our Societies Arise, Thrive and Fall. They discuss Mark’s view that being able walk into a cafe filled with others and not be attacked illustrates what makes human societies distinct and so successful. Mark explains why he is far more interested in questions about when war and other events occur than with traditional issues such as the genetic origins of human behavior. The three discuss Dehumanization and its Chimp equivalent, Dechimpanizeeization, and how they lead to the division of societies, friend turning against friend, and genocide. They discuss the conditions under which foreigners are embraced and whether the US might ever enter into a post-racial society where group differences don’t matter and immigrants are more easily accepted.ResourcesMark Moffett’s BioMark Moffett’s PhotographyThe Human Swarm: How Our Societies Arise, Thrive, and FallTranscript

John Schulman is a research scientist at OpenAI. He co-leads the Reinforcement Learning group and works on agent learning in virtual game worlds (e.g., Dota) as well as in robotics. John, Corey, and Steve talk about AI, AGI (Artifical General Intelligence), the Singularity (self-reinforcing advances in AI which lead to runaway behavior that is incomprehensible to humans), and the creation and goals of OpenAI. They discuss recent advances in language models (GPT-2) and whether these results raise doubts about the usefulness of linguistic research over the past 60 years. Does GPT-2 imply that neural networks trained using large amounts of human-generated text can encode “common sense” knowledge about the world? They also discuss what humans are better at than current AI systems, and near term examples of what is already feasible: for example, using AI drones to kill people.ResourcesJohn SchulmanOpenAIBetter Language Models and Their Implications (GPT-2)Transcript

Daniel Max, staff writer at The New Yorker and author of Every Love Story is A Ghost Story, a biography of David Foster Wallace, speaks with Corey and Steve about his first book, The Family that Couldn’t Sleep. The discussion covers the emerging genre of literary non-fiction, Daniel’s process of writing The Family that Couldn’t Sleep, and how he approached and gained the trust of the family at the heart of the story. Corey probes Daniel about how he handled the complex scientific characters, Carl Gajdusek and Stanley Prusiner, who led research into prion disease for 40 years. Daniel recounts how Shirley Glasse (now Lindenbaum) discovered how prions were transmitted through ritual cannibalism in Papua New, a critical step in solving the mystery of what causes of the disease, but how credit was given to Gajdusek. The three discuss the painfully slow pace of research and the inspiring story of a young couple, Eric Minikel and Sonia Vallabh, who have changed careers to dedicate their lives to finding a cure.Resou

Steve and Corey speak with Stuart Firestein (Professor of Neuroscience at Columbia University, specializing in the olfactory system) about his two books Ignorance: How It Drives Science and Failure: Why Science Is So Successful. Stuart explains why he thinks that it is a mistake to believe that scientists make discoveries by following the “scientific method” and what he sees as the real relationship between science and art. We discuss Stuart’s recent research showing that current models of olfactory processing are wrong, while Steve delves into the puzzling infinities in calculations that led to the development of quantum electrodynamics. Stuart also makes the case that the theory of intelligent design is more intelligent than most scientists give it credit for and that it would be wise to teach it in science classes.ResourcesStuart FiresteinFailure: Why Science Is so SuccessfulIgnorance: How it drives scienceTranscript

Corey and Steve continue their discussion with Joe Cesario and examine methodological biases in the design and conduct of experiments in social psychology and ideological bias in the interpretation of the findings. Joe argues that experiments in his field are designed to be simple but that in making experimental set ups simple researchers remove critical factors that actually matter for a police officer to make a decision in the real world. In consequence, he argues that the results cannot be taken to show anything about actual police behavior. Joe maintains that social psychology as a whole is biased toward the left politically and that this affects how courses are taught and research conducted. Steve points out the university faculty on the whole tend to be shifted left relative to the general population. Joe, Corey, and Steve discuss the current ideological situation on campus and how it can be alienating for students from conservative backgrounds.ResourcesJoseph Cesario’s LabA new look at racial dispariti

Corey and Steve talk with Joe Cesario about his recent work showing that, contrary to many activist claims and media reports, there is no widespread racial bias in police shootings. Joe discusses his analysis of national criminal justice data and his experimental studies with police officers in a specially designed realistic simulator. He maintains that evidence suggests that racial bias does exist in other uses force of force such as tasering but that the decision to shoot is fundamentally different and driven by facts about criminal context in which officers find themselves rather than race.ResourcesExample of officer completing shooting simulatorA new look at racial disparities in police use of deadly forceIs There Evidence of Racial Disparity in Police Use of Deadly Force?
