The Reality Check

Sharks are so old. How old are they? They're so old that you'll be shocked to hear of all of the things that haven't been on earth as long as sharks. Darren gives us a unique history of the earth by exploring the ages of very old things and contrasting them to the very long time that sharks have been around. Adam looks at a recent appearance of Jim Carrey that has fans wondering if he's been replaced with a clone, a double or a makeup artist in an elaborate mask.

What impact do digital devices like laptops, tablets and smart phones, both inside and outside of the classroom, have on childrens' ability to learn? Adam questions the assumption that these devices are always positive, and examines the research on the topic. Darren gives us two book reviews. First up is Enshittification by Cory Doctorow, which examines what seems to make good companies kind of terrible, and then it's Breakneck: China's Quest to Engineer the Future by Dan Wang, which looks at what factors make the US and China different.

There has been a lot of news lately about Moltbook AI, a network of Artificial Intelligence agents who are interacting with each other in great numbers in a virtual space. Darren separates fact from fiction as he explores many fascets of this emerging technology and what it could mean for the future. Then Adam looks into just how the surveys they use to get answers for the game show Family Feud really work.

This week's show is all about the law. Growing up our parents told us all kinds of things were illegal, such as driving with the dome light on in the car, riding in the back of a pickup truck, skipping school or playing Ding Dong Ditch. Adam explores whether any of these things are actually illegal, and asks if our parents were lying to us or just mistaken themselves. Then Darren investigates the effect of Canadian politeness and the law. Does saying you're sorry mean that you're actually admitting to being guilty of something?

After decades of doing the podcast we have finally gotten around to recording an episode entirely dedicated to orange cats. Darren examines just what's going on with orange cats acting weird on the Internet and in real life. Is Orange Cat Energy a thing or are humans just stereotyping orange taby cats? Adam explores the world's most popular orange cat, Garfield, as he tries to find out just what kind of cat he actually is.

For our first show of 2026 Adam looks at the efficacy of Infant Simulator Programs, which involves giving a fake baby to high school kids to discourage teen pregnancy. Darren gives us a review of three books, "The Thinking Machine: Jensen Huang, Nvidia, and the World's Most Coveted Microchip" by Stephen Witt, "The Philosopher in the Valley: Alex Karp, Palantir, and the Rise of the Surveillance State" by Michael Steinberger and "Peak Human: What We Can Learn From History's Greatest Civilizations" by Johan Norberg.

As Christmas approaches we bring you the history of two popular decorations you might see this holiday season. Darren looks at the history of the mistletoe as a decoration, symbol of fertility and God killer. Adam looks at the first use of lights on a Christmas tree and it may be older than you think!

With AI safety still underrated yet imperative, in this bonus episode of the show we share the Introduction to "Uncontrollable: The Threat of Artificial Superintelligence and the Race to Save the World" by Darren McKee.

Today, December 2nd, is Giving Tuesday. Darren gives an overview of the concept of Effective Giving, with some tips on how your charitable donations could will lead to the most good in line with your own priorities. Adam tackles a few claims about the Mona Lisa, inspired by not all that evidence based viral clips. What were the original colours of this painting, and did it only become popular after being stolen years ago?

Two years ago we interviewed Yoshua Bengio, the prominent AI researcher, about his long career in AI where he helped build the foundations for the tools millions use around the world every day. We discussed the future of AI systems, including the importance of AI safety. Since then, Yoshua Bengio has continued to achieve great success in his career in both work on AI and raising awareness about their risks. This bonus episode is a repeat of Darren McKee and Adam Gardner's interview with him from 2023.

We've got two special guests on the latest show! TRC alumni Pat and Cristina join us with a couple of great segments. First Critina tackles a number of myth about diabetes, including her own recent serious experience with DKA or diabetic ketoacidosis. Then Pat delights us with another round of everyone's favourite mostly guessing game Name That: Spot the Fake edition. This game has a special twist that really challenged the contestants.

Next is Algospeak by Adam Aleksic, which examines how social media algorithms inflence language online and in the real world.

With Halloween coming up we bring you some spooky segments on zombies and vampires! Darren looks at the thought experiment about philosophical zombies also known as p-zombies. Does this idea make that much sense? Then Adam looks at cases of tuberculosis taking place in New England which, to people without a proper understanding of the germ theory of disease, were thought to be vampirism.

Why does air conditioning seem to be more common in North America than in Europe or other places around the world? Adam looks at the many factors that can encourage or hinder adoption of AC in various places. Darren gives us book reviews on a variety of topics with "What Is Real? The Unfinished Quest for the Meaning of Quantum Physics" by Adam Becker and "Good and Real: Demystifying Paradoxes from Physics to Ethics" by Gary Drescher.

How is intelligence portrayed in works of fiction? In books, films and TV, we often see depictions of very smart of sometimes less intelligent people, but it's never totally realistic. Darren leads a conversation about various fictional portrayals of intelligence from Ender Wiggin and Sherlock Holmes to Joey Tribbiani and Homer Simpson. When do they get it right and why, and what do they often get wrong?

Wood you believe that it's all about trees on the latest episode of The Reality Check podcast? Here are two classic segments about trees. First up is an interview with tree expert Owen Clarkin who gets to the root of many tree facts. That segment may have planted the seeds for a future segment so we leave you with Pat who looks into claims that the Amazon rainforest is the Earth's lungs.

It's a different kind of show this week as Darren and Adam discuss the recently released Superman film. The movie, directed by James Gunn, stars David Corenswet as Superman. The discussion includes a look at box office results and factors contributing to them, criticism of art and the various things we like and dislike about the film. Though it isn't a particularly sciencey topic, we can't help but apply our own brand of critical thinking to some aspects of the film.

The film is currently in theatres worldwide and available to purchase digitally. It's recommended that you...

Is AI making us dumber? Darren looks into a recent study, which spawned some less than great press coverage, trying to assess where or not using LLMs is making us less intelligent. We didn't really come to very good conclusions because we've been using too much AI. Adam gives an overview of mentalism, inspired by some recent podcast appearances by Oz Pearlman which have gone viral and brought some mainstream attention to this practice.

Could it be that dire wolves are no longer extinct? Researchers at Colossal Biosciences claim to have accomplished de-extinction of these long extinct wolves.

Sadly, we recently got the news that our friend and frequent TRC contributor Dr. Stuart Farrimond passed away.  Stuart was a medical doctor who had a brain cancer diagnosis at age 25.  His treatment and side effects meant he had to stop practicing medicine.  Stu reinvented himself as a food science expert - appearing on countless television and radio shows.  He later became a best selling author of science education books.  He will be missed.

Who would win in a fight, 100 men or 1 gorilla? If you're thinking that question is too vague then you'll love Darren's analysis of the situation. Adam looks at claims that we've found evidence of alien life on an exoplanet called K2-18B. I'm not saying it's aliens but… listen to the episode to find out!

The Telepathy Tapes is a popular podcast that tells the story of non verbal people showing evidence of psychic abilities and logging on to a psychic virtual chat room called The Hill. Adam looks into how realistic these claims are given what we know about Facilitated Communication. Darren looks into some AI programs that seem to have been cheating at chess! What are they doing and what could this mean for the future of Artificial Intelligence?

Is Tim Hortons Canadian? Darren takes a look at the history of the popular coffee and donut chain to see just how Canadian it is and what it even means to be a Canadian company. Adam dives into some recent news which suggests that there are massive structures underneath the Great Pyramid of Giza. Is this even possible? Could that structure be a Tim Hortons restaurant?

Could Artificial Intelligence do a better job of recording a podcast than Darren and Adam? For this bonus episode we try something a little different. Darren gave Google's NotebookLM the introduction Uncontrollable, his book on AI safety, and asked it to generate a podcast based on the content. Listen to what it produced! A somewhat convincing exchange between two virtual podcast hosts talking about concerns about the looming threat of AI. Following this simulated episode the real human hosts of The Reality Check podcast will share what we thought of it.

Joe Nickell, the world renowned paranormal investigator, died earlier this week at the age of 80. He was a great inspiration to us here at The Reality Check and it was a great pleasure for some of us to have met him back in 2009 at The Amazing Meeting. At that time we recorded this interview, originally used in episode 53 of the show, where we talk with Joe Nickell about his fascinating career.

Darren revisits a topical segment from the past looking at Jevons' Paradox which suggests that as a resource becomes more efficient, it may paradoxically be consumed more. Then Adam looks at some recent controversies about artificial colouring in Froot Loops cereal, how those are labeled in the US and Canada and what that means.

With Valentines Day coming up we are taking this opportunity to revisit a romantic segment we did five years ago with Dr. Cheryl Harasymchuk. In this interview she discusses the work she does in the Positive Activities in Intimate Relationships (PAIR) Lab at Carleton University in which they study factors that promote and hinder positive activities in intimate relationships.

It is often said that cats are responsible for the death of countless birds. Adam looks at where these numbers come from and wonders whether they are all that accurate. Darren gives a review of four books which he recently read. He'll share an AI and human summary of "My Promised Land: The Triumph and Tragedy of Israel" by Ari Shavit, Enemies and Neighbors: Arabs and Jews in Palestine and Israel, 1917-2017″ by Ian Black, "Unit X: How the Pentagon and Silicon Valley Are Transforming the Future of War" by Raj M. Shah and Christopher Kirchhoff, and "On Freedom" by...

It's the 700th episode of The Reality Check podcast! On this special show we look back at the last 16 years to see how much things have changed since way back in 2008. Darren looks at the history of podcasts and how far we've come and then Adam looks at which false beliefs have become more or less over time since the show started.

When it comes to evolution many focus on what Jean-Baptiste Lamarck got wrong with his model of inheritance.  Darren looks at what he got right and considers his discoveries in light of the scientific understanding of the world of his time.  Adam, based on first hand anecdotal evidence of many cats and dogs, wonders what pets see when they looking at various types of TVs and computer monitors.

Could an AI rewrite its own code? Has it perhaps already done so? Darren looks at the story which suggests that an AI Scientist, developed by Sakana AI, was able to change its own source code. What exactly happened and are you worried enough about it? Then Adam investigates the truth behind a viral claim that we say "hello" on the telephone because of Graham Bell's fiancée and assistant, Margaret Hello.

After having watched all six Sharknado films Adam decides to do some research into the science of these not at all ridiculous films, uncovering the truth about the plausibility and historical precedent for a tornado filled with living sharks. Darren gives us a book review of Renée DiResta's Invisible Rulers: The People Who Turn Lies into Reality, which explores how powerful influencers are able to affect what people believe.

Could meditation ever be harmful? Darren examines the evidence to determine if meditation, which can have many benefits, might sometimes have a negative impact on people's lives. Adam looks at the idea of cavemen and wonders if, as their name suggests, that they really spent all that much time in caves.

What's the difference between a bar of soap and the stuff we use to clean dishes, laundry and cars, and can you just use any of those in the shower? Adam tries to find out whether the stuff that's fit for baby ducks if good enough for you skin. Darren gives us a review of Determined: The Science of Life Without Free Will by Robert Sapolsky, which asks interesting questions about free will, whether we have it and what the implications are.

We look at some fundamental ways of cultivating critical thinking on the latest show.  Darren looks at some common cognitive biases and logical fallacies and how to use these in order to have a better more accurate understanding of the truth of the things we face every day.  Then Adam looks at the science behind the  belief that you should let your leftovers cool down at room temperature before putting them in the fridge.
