  SIO528: The Marshmallow Test Is Mostly BS, and It's Not the Only Classic Psych Test Like That 29.09.2026 50min

  Kids are weird, like really weird, but in a fun way? Dr. Jenessa Seymour is back to tell us about some classic child development paradigms that really need to be reevaluated. Depending on when you learned about these experiments, you were either taught that they were the gospel truth, with established ages where kids can and cannot pass these tests, and major consequences for late development, or maybe you heard that recent studies show it's a bit more complicated. Still makes for some cute and funny demonstrations either way. Sources: The marshmallow test is really about trust The "curse of knowledge" Autistic kids pass theory-of-mind tests on a computer Passing the theory-of-mind test with implicit looking measures at 15-months-old and 13-months-old Kids pass the conservation test sooner when they do it themselves Are you an expert in something and want to be on the show?

  SIO530: Did AI Actually "Solve" That Famous Math Problem? 26.09.2026 51min

  You've seen the headline: AI "solved" one of math's Millennium Prize problems. Thomas and Jenessa (here as a friend, not an expert) are joined by David Souther, a software engineer and LLM researcher, who's SO annoyed about it. Why did he answer Jenessa's text in all caps? And what's the deal with a rushed phone call between OpenAI and a math professor? Are you an expert in something and want to be on the show? Apply here!

  Dr. Tania Lombrozo, professor of psychology at Princeton University (affiliated with its philosophy and cognitive science departments), joins Thomas to discuss her forthcoming book Why We Ask Why: The Science of Explanation and the Human Drive to Understand. Why are humans so driven to explain things, but only some things? Why does understanding go beyond just being able to predict?

  SIO526: Why Is College So Expensive? 01.09.2026 54min

  David O'Brien, higher education policy scholar with the California Community Colleges System, is back to answer the question Thomas posed last time: why is college so expensive? They get into tuition vs. total cost of attendance, the dirty little secret of private university pricing, administrative bloat, the amenities arms race, and why the people loudest about college costs are likely well-off, but getting very little financial aid.

  Some More News Is COMPLETELY WRONG About Spider-Man Brand New Day 31.08.2026 1h 38min

  I cannot stop thinking about Cody from Some More News's video in which he could not stop thinking about Spider-Man: Brand New Day. Cody is INCREDIBLY sure that you're an idiot incapable of watching movies or consuming art if you don't agree with his conception of what the ending of Brand New Day meant. The problem is... Cody gets about a billion things wrong and his arguments are terrible. This was going to be just a Patreon bonus of Serious Inquiries Only but I wanted to put it up on YouTube so it's going out to everyone! WATCH HERE!

  Part 2! Dr. Eric Jaffe returns to actually treat the cancer this time: why radiation is basically catching your kid smoking and making him finish the carton, how CRISPR turns your own T cells into an assassin squad, and why oncolytic viruses are just Jurassic World Dominion for tumors.

  SIO522: College Is Impossibly Expensive. But It's Not Because of Bogus Degrees. 21.07.2026 40min

  Part 2! Thomas is joined again by David O'Brien, a higher education policy scholar with the California Community Colleges system, to finish dismantling The Daily's take on Trump's student loan crackdown. Reagan, Pell Grants, and decades of quiet state defunding all get their due, plus a theory on why tuition keeps climbing that has nothing to do with cosmetology degrees.

  Thomas is joined by David O'Brien, a higher education policy scholar who works for the California Community Colleges system, to pick apart Trump's new rules threatening to cut off student loans and Pell grants from "low-earning" degree programs, and to fact-check The Daily's recent take on the same story. The real history runs through Reagan, Prop 13, and decades of quiet austerity nobody on that podcast wants to mention.

  SIO520: My Talk at SkeptiCal - Selective Skepticism Is Not Skepticism 30.06.2026 48min

  Thanks so much to the folks at SkeptiCal for inviting me! Though the talk does deal with the Butler shooting, I thought some way different stuff for this including a ridiculously overwrought hypothetical, my favorite kind! And, I found a Young Turks video where they are apparently Joe Rogan now!

  SIO519: People Are Misinterpreting Obsession in Very Revealing Ways 24.06.2026 1h 1min

  The "nice guy" is the villain. We watched Obsession and cannot stop thinking about it. It has so much to say about gender, consent, "nice guys" and more. And it scarred Lydia for life.

  SIO518: Biological Definitions Do Not Do What Richard Dawkins Says They Do 16.06.2026 1h 3min

  Thomas is joined by Dr. Eric Jaffe, biologist, dinosaur enthusiast, and high school biology teacher, for a conversation that starts with a deceptively simple question: what are biological definitions actually doing? It turns out that biology is far more like history than math, and that difference has enormous consequences for anyone trying to weaponize phrases like "the biological definition of sex." Dr. Jaffe walks through why definitions in inductive sciences are descriptive, not prescriptive, and what that means for species, chromosomes, fungi, LeBron James, and trans people. "Exceptions aren't the exceptions in biology. They are built into what we call biological systems." Plus: Patreon Q&A questions on alien DNA, how new chromosomes evolve, the 97% chimp figure, CRISPR vs. what came before, and Trump's research budget cuts.

  SIO517: How Is It That 9 Days in Space Means Weeks of Rehabilitation? 09.06.2026 1h 4min

  Thomas is joined by Dr. Jenessa Seymour to dig into the brain science behind a surprisingly strange phenomenon: why do astronauts who spent just nine days in space need weeks of physical therapy to walk normally again? The answer turns out to involve ancient calcium carbonate ear stones, the same material crabs use for shells, a multi-layered sensory system your brain is constantly running without your knowledge, and a wild evolutionary theory about why motion sickness exists at all. Also: why pilots fly perfectly good planes directly into the ground, and what deaf NASA research participants revealed about how proprioception actually works. Come see me at SkeptiCal!

  SIO516: How a Botched 1840 Census "Proved" Freedom Made Black Americans Disabled, with Sari Altschuler 31.05.2026 45min

  The history of disability rights is often treated as a modern story, but what if that framing misses centuries of earlier, more complicated history? This week, Thomas is joined by Professor Sari Altschuler, Associate Professor of English at Northeastern University, to explore her new book Before Disability: A History of American Citizenship. In the book, Professor Altschuler traces how disability and citizenship have been intertwined since the founding of the United States, and what that reveals about who America decided belonged and who didn't. In the early Republic, many physical and mental differences were accommodated within the framework of citizenship; by the antebellum era, however, those same differences had been weaponized as tools of racial exclusion, and eventually as justification for eugenics. Thomas and Professor Altschuler dig into the intersections of race, disability, and civic belonging, and what early American history can teach us about the fights happening today.

  SIO514: No Part of the "62 Million Men Enrolled In Online Rape Academy" Claim Was Correct 18.05.2026 54min

  You might have seen the CNN article from a while back entitled Exposing a global 'rape academy'. While most of the article is technically true, the broad takeaway that virtually everyone had (including me) was wildly, irresponsibly false. Even if you came across debunks of this, there's a good chance that I'm debunking this even more than you've seen. I don't think people have fully grasped how misleading it was.

  SIO513: Debunking Butler Conspiracy Theories in Descending Order by Scope 02.05.2026 1h

  SIO512: NO It Was Not Staged. Stop Being Joe Rogan. 30.04.2026 59min

  It wasn't staged. None of them were staged. Yes Trump was shot in the ear. I thought you all were doing a bit, but apparently you weren't. This isn't good and you should stop doing it, please. In discussing this current shooting, I found that way too many of you think that it was a hoax and even more think that Trump wasn't shot in the ear. So, let's go through the Butler shooting and see why YES HE F-CKING WAS.
