Corey and Steve talk to Claude Steele of Stanford about his article “Why Campuses are So Tense?”. The essay explores stereotype threats across racial lines. Colorblindness is a standard of fairness, but what are the costs of ignoring our differences? Claude describes his research on minority underperformance and why single sex colleges may contribute to women’s success. Corey describes why he believes his daughter’s experience is a counterexample to the findings of the experiments that led the Supreme Court to outlaw segregation. The three discuss parenting in a diverse world and how ethnic integration differs between Europe and the US.ResourcesTranscriptClaude SteeleWhy Campuses are So Tense?Whistling Vivaldi: And Other Clues to How Stereotypes Affect UsIn Struggle: SNCC and the Black Awakening of the 1960s

Corey and Steve talk with MSU Neuroscientist A.J. Robison about why females may be more likely to suffer from depression than males. A.J. reviews past findings that low testosterone and having a smaller hippocampus may predict depression risk. He explains how a serendipitous observation opened up his current line of research and describes tools he uses to study neural circuits. Steve asks about the politics of studying sex differences and tells of a start up using CRISPR to attack heart disease. The three end with a discussion of the psychological effects of ketamine, testosterone and deep brain stimulation.Topics01:18 – Link between antidepressants, neurogenesis and reducing risk of depression13:54 – Nature of Mouse models23:19 – How you tell whether a mouse exhibits depressive symptoms32:36 – Liz Williams’ serendipitous finding and the issue of biological sex45:47 – A.J.’s research plans for circuit specific gene editing in the mouse brain and a start up’s plan to use it to tackle human cardiovascular disea

Kaja Perina is the Editor in Chief of Psychology Today. Kaja, Steve, and Corey discuss so-called Dark Triad personality traits: Narcissism, Machiavellianism, and Psychopathy. Do these traits manifest more often in super successful people? What is the difference between Sociopathy and Psychopathy? Are CEOs often “warm sociopaths”? Can too much empathy be a liability? Corey laments Sociopathy in academic Philosophy. Kaja explains the operation of Psychology Today.

Steve and Corey talk to Adam Dynes of Brigham Young University about whether voting has an effect on policy outcomes. Adam’s work finds that control of state legislatures or governorships does not have an observable effect on macroscopic variables such as crime rates, the economy, etc. Possible explanations: parties push essentially the same policies, politicians don’t keep promises, monied interest control everything. Are voting decisions just noisy mood affiliation? Perhaps time is better spent obsessing about sports teams, which at least generates pleasure.Topics1:22 – What is retrospective voting?5:43 – Research findings on retrospective voting14:02 – Uniparty/Monied interests?17:23 – Martin Gilens’ research23:10 – Are people just voting based on noise or mood affiliation?27:13 – Bryan Caplan – Myth of the Rational Voter34:35 – Is time better spent obsessing about sports teams, which at least generates pleasure?39:42 – After the fall of Athens, was democracy commonly referred to as irrational mob rule?48:

Steve and Corey talk to Elizabeth Kolbert, author of the Sixth Extinction, about the current state of the climate debate. All three are pessimistic about the possibility that emissions will be substantively reduced in the near term, and they discuss technologies for removing carbon from the atmosphere. They explore uncertainty in the models regarding temperatures rise and precipitation, and contemplate a billion people are on the move in response to climate change and population increase. They ask: what is more of a threat to humanity in the coming century, runaway AI or runaway climate change?ResourcesTranscriptElizabeth Kolbert (The New Yorker)Field Notes from a Catastrophe: Man, Nature, and Climate ChangeThe Sixth Extinction: An Unnatural HistoryNew York City Sea WallMiami MitigationJobs and AICarbon Capture

Corey and Steve talk to Meghan Daum about her new book “The Problem With Everything: My Journey Through The New Culture Wars”. Meghan describes how she became aware of the “Red Pill” through what she calls “free speech YouTube” videos. The three ask whether their feeling of alienation from Gen-Z wokeness is just a sign of getting old or reflects principles of free speech and open debate. Megan argues that Gen-Z’s focus on fairness leads to difficult compromises. They discuss social interactions in the pre-internet, early-internet, and woke-internet eras.ResourcesTranscriptAuthor WebsiteMeghan Daum on MediumThe Problem with Everything: My Journey Through the New Culture Wars

Steve and Corey talk with Steven Broglio, Director of the Michigan Concussion Center, about concussion risk, prevention and treatment. Broglio describes how the NCAA emerged from the deaths that almost led Theodore Roosevelt to outlaw college football. He also explains recent findings on CTE, why females may be at greater concussion risk, and why sleep is critical to avoiding long-term brain injury. They discuss how new rules probably make football safer and debate why New England is so down on kids playing football. Steve wonders whether skills are in decline now that some schools have eliminated “contact” in practices.ResourcesTranscriptSteven Broglio (Faculty Profile)Michigan Concussion CenterNeuroTrauma Research LaboratoryNCAA-DoD Grand Alliance: Concussion Assessment, Research, and Education (CARE)

Our guest, Barbara O’Brien, explains why we don’t know much about conviction error outside of murder cases, making error rates for the vast majority of crimes: misdemeanors, sexual assaults, armed robbery, etc. a “dark ocean”. She explains factors that contribute to wrongful convictions including mistaken cross-racial identification in sexual assault cases. Barbara also talks about the surprising frequency of “rain damage” to evidence rooms and why Texas leads the way in both executions and criminal justice reform. The two consider why having your death sentence commuted to life in prison means you are actually less likely to ever to be released.ResourcesTranscriptBarbara O’Brien (Faculty Profile)The National Registry Of Exonerations

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
