Serious Inquiries Only

Serious Inquiries Only

Join Thomas for some critical thinking on questions of science, philosophy, skepticism and politics. These serious topics are discussed with some serious guests, but in an entertaining and engaging way! This is not your typical interview podcast; it’s a friendly dialogue, conducted thoughtfully and with plenty of humor. It's Serious Inquiries Only; but like, not boring or anything.

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 a...

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.

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.

Part 1! Dr. Eric Jaffe, the biology teacher who keeps naming proteins after cartoon characters, returns for a two-part cancer deep dive. Today: what cancer actually is at the cellular level, why elephants barely get it, why whales get it even less, and why the "they're hiding the cure" conspiracy falls apart the second you learn who actually funds the research.

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.

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!

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.

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."...

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 wi...

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 citiz...

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 gr...

We continue the pruning of idiotic Butler Shooting conspiracy theories. Once we establish the facts using actual sources, what room is there left for a conspiracy or staging theory?

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-CKIN...

Well, what do you know - it's a day that ends in y so the internet has a woman to hate. You might have seen some of the chatter about child-hating Chappell Roan lately, and it's just so depressing every single time one of these hate campaigns rears its ugly head. Lydia joins the show as resident Chappell Roan fan to discuss what actually happened, and why society so quickly jumps on these opportunities to hate women.

Popular media will tell you that placebos, inert inactive substances taken as if they’re medication, can work miracles. …Placebos don’t “work”. But what does that even mean? And if that’s true, why would we include a placebo group in a study? Is there anything remotely like a “true”’placebo effect, where belief in a medication could influence the body?

“Yes we can” vote and protest our way out of authoritarianism.

It’s a classic case of academic literature never making it to mainstream consumption. Hang around social media long enough and you’ll hear that we’re basically screwed. A complete fascist take over is either extremely likely, inevitable, or it’s already here. And there’s not much we can do about it. Unless some other country inv...
