Something You Should Know

If you want a conversation to feel more engaging and connected, there’s a small, often overlooked detail that can quietly shape how the other person experiences you before either of you even says a word. And it all has to do with your phone. This episode begins with research revealing what that detail is and why it matters more than most people realize. https://pmc.ncbi.nlm.nih.gov/articles/PMC12110250/

You’ve likely experienced that rare moment when you just click with someone. Conversation flows. It seems effortless – it’s feels magical. But what’s actually happening in those moments — and why doesn’t it happen with everyone? Journalist Kate Murphy joins me to explain the science behind interpersonal synchrony, the conditions that make clicking more likely, and why these moments feel so meaningful. Kate has written for The New York Times and The Wall Street Journal and is author of Why We Click: The Emerging Science of Interpersonal Synchrony. https://amzn.to/4sM4a04

We hear the word excellence everywhere — but what does it really mean to pursue it? Do we need to strive for excellence in everything we do? Is it okay to be average at some things? And how do you avoid chasing what looks like excellence but actually leads to burnout or dissatisfaction? Brad Stulberg explains the difference between true excellence and what he calls “pseudo-excellence,” and how to pursue mastery in a way that leads to both high performance and deep satisfaction. Brad is a writer, researcher, performance coach, and author of The Way of Excellence: A Guide to True Greatness and Deep Satisfaction in a Chaotic World. https://amzn.to/4qY237s

Written communication strips away tone, facial expression, and nuance — which is why texts and emails are so easy to misinterpret. Sarcasm, humor, and intent can get lost, sometimes with awkward or costly consequences. This episode begins with how emojis can restore subtlety to digital communication — if you know which ones actually help and which ones make things worse. https://www.sciencedirect.com/science/article/abs/pii/S0747563221002946?utm

Some of the greatest ideas — and even entire careers — were never planned. Potato chips, penicillin, and Post-it Notes were all accidents. Success often comes not from careful design, but from noticing opportunities hidden inside unexpected events. Innovation expert Paul Sloane explains how breakthroughs really happen and how you can position yourself to recognize them when they appear. Paul is author of The Art of Unexpected Solutions (https://amzn.to/3ZeKEvw).

People naturally gravitate toward others who think, act, and believe the same way they do. We form tribes — social, political, professional — and those bonds can feel deeply comforting. But this instinct also shapes how we see outsiders and influences cooperation, conflict, and culture itself. Cultural psychologist Michael Morris explores why humans evolved this instinct and whether it ultimately helps or harms us. He is author of Tribal: How the Cultural Instincts That Divide Us Can Help Bring Us Together (https://amzn.to/4pJ6K4n).

And finally, weight loss is one of the most common New Year’s resolutions — and one of the quickest to be abandoned. Research suggests that a handful of surprisingly small habits can dramatically improve your chances of sticking with it. We wrap up with what actually works. https://pubmed.ncbi.nlm.nih.gov/34259635/

When people talk about the “culture” – why do they mean? What is culture. You probably use the word in conversation and you have a sense of what it means but it is actually a difficult word to define. Here to define it and explain why it is so important to understand what culture is and how it changes is Marcus Collins. He is a clinical assistant professor of marketing at the Ross School of Business, at the University of Michigan and recipient of Advertising Age’s 40 Under 40 award.

It is a little strange that there is such a fitness craze in America yet so many people are not physically fit at all. The medical evidence is pretty clear that being physically fit and keeping your weight under control is so important to a long and healthy life. So why are so many people not motivated to do it and how can you find the motivation to start if you are not feeling inclined? Joining me to talk about this is Natalia Petrzela. She is an historian of contemporary American politics and culture as well as a fitness instructor and she is author of the book Fit Nation: The Gains and Pains of America’s Exercise Obsession (https://amzn.to/48V5LGb)

When you get sick, your instinct is to withdraw — crawl into bed, cancel plans, and avoid people. As unpleasant as that feels, it turns out that instinct may be doing something surprisingly important for everyone else. This episode begins with why feeling miserable when you’re sick is actually a good thing. https://www.sciencedaily.com/releases/2016/01/160107094128.htm

If you really want to know what’s most likely to seriously injure or kill you, talk to an ER doctor. They see patterns most of us never think about — and many of the dangers are far more ordinary than you’d expect. Ashley Alker joins me to share the risks she sees again and again — and how to avoid them. She’s an emergency medicine physician, medical consultant for shows on Netflix, Hulu, HBO, and Disney, and author of 99 Ways to Die and How to Avoid Them (https://amzn.to/3NlW91w)

Friction is everywhere. It slows you down, wears things out, and wastes energy — yet without it, you couldn’t walk, drive, or even stand still. What would life actually be like if friction didn’t exist? And why is understanding it so important? Jennifer R. Vail explains the invisible force that quietly shapes nearly everything you do. She founded DuPont’s first tribology research lab, delivered the TED Talk The Science of Friction (viewed over two million times), and is author of Friction: A Biography (https://amzn.to/454i7wf)

What if one of the best-performing investments over the last few decades wasn’t stocks, real estate, or gold — but LEGO? It sounds absurd, yet when researchers tracked the resale value of LEGO sets, they found returns that beat many traditional investments. We begin by looking at which sets gain value, why they do, and what makes some toys unexpectedly valuable. https://www.sciencedirect.com/science/article/abs/pii/S0275531921001604

Life rarely goes according to plan. Careers shift, relationships change, health issues arise, and unexpected events force us to adapt — often before we feel ready. Since change is unavoidable, the real question becomes: how do you respond when life throws you off course? Maya Shankar joins me with powerful insights on navigating uncertainty and finding meaning when plans fall apart. Maya is a cognitive scientist, former senior advisor in the Obama White House, Senior Director of Behavioral Economics at Google, host of A Slight Change of Plans, and author of The Other Side of Change: Who We Become When Life Makes Other Plans (https://amzn.to/4qAad5U)

Time is one of the few constants in life — yet our experience of it is anything but constant. Why does time seem to fly on vacation but crawl in traffic? Why do many people feel that time speeds up as they get older? And what is time, really? Sten Odenwald helps untangle these questions. He’s a longtime astronomer, Director of NASA’s STEM Resource Development Project, and author of The Essential Book of Time (https://amzn.to/3N6qNfm).

And finally, legendary relationship researcher John Gottman says long-term relationships don’t succeed because of romance, passion, or even communication skills alone.

This episode begins with how easily your senses can be influenced. https://www.npr.org/sections/thesalt/2014/12/31/370397449/food-psychology-how-to-trick-your-palate-into-a-tastier-meal#

When you recognize someone, it usually happens instantly — but what exactly are you recognizing? How much of a face do you need to see? Why are some people incredibly good at recognizing faces while others struggle or are completely face blind? And how does facial recognition software compare to the human brain? Sharrona Pearl joins me to explore why face recognition varies so dramatically between people. She is associate professor of medical ethics and history at Drexel University and author of Do I Know You?: From Face Blindness to Super Recognition (https://amzn.to/3TWc0VX).

We like to believe we think clearly and rationally — but much of the time our brains are running on autopilot. That’s when bad decisions, faulty reasoning, and unnecessary mistakes creep in. Shane Parrish explains how to slow down your thinking, avoid mental traps, and make better decisions in everyday moments. Shane is an entrepreneur whose work is used by Fortune 500 companies and professional sports teams, host of The Knowledge Project podcast, and author of Clear Thinking: Turning Ordinary Moments into Extraordinary Results (https://amzn.to/3Hl0FHj).

Guilt feels terrible — and that’s exactly what makes it so effective. While we tend to see guilt as something to avoid, it may actually play an essential role in helping us learn, repair relationships, and behave more ethically. Christopher Moore explains why guilt exists, how it evolved, and why feeling guilty can sometimes be a very good thing. Christopher is a professor of psychology and former dean of science at Dalhousie University, whose work has been cited in Psychology Today, Today’s Parent, and The New York Times. He is author of The Power of Guilt: Why We Feel It and Its Surprising Ability to Heal (https://amzn.to/3Nrt051).

Plagiarism seems like a clear-cut wrongdoing — but the reality is far more complicated. People plagiarize more often than you might think, sometimes without even realizing it. And in some cases, you can be accused of plagiarism even if you’ve never seen the original work. With only so many ways to tell a story or write a song, where does coincidence end and plagiarism begin? Roger Kreuz joins me to explore this fascinating gray area. He is Associate Dean and professor of psychology at the University of Memphis, a columnist for Psychology Today, and author of Strikingly Similar: Plagiarism and Appropriation from Chaucer to Chatbots. (https://amzn.to/4soVFaS).

And finally, there’s a widespread belief that dark roast coffee has more caffeine than light roast — or that espresso packs far more caffeine than a regular cup of coffee. Both ideas sound logical, but they’re not quite right. We wrap up by explaining what actually determines caffeine content and why these myths persist. https://www.healthline.com/nutrition/light-vs-dark-roast-coffee

This episode begins with research revealing which parenting behaviors leave the strongest, longest-lasting impressions — and how they shape adult relationships. https://time.com/4097995/parenting-kids-remember/

Some emotions can completely hijack your day. Anger, anxiety, frustration, and stress often feel automatic — as if you have no control once they show up. But that’s not actually true. Dr. Ryan Martin explains science-backed ways to regulate emotions both before they spiral and in the moment. Ryan is Dean of the College of Arts, Humanities and Social Sciences and Professor of Psychology at the University of Wisconsin–Green Bay, and author of several books on emotions, including Emotion Hacks: 50 Ways to Feel Better Fast (https://amzn.to/4qrv9fj).

Laughter feels good — but why do we do it? And why do humans laugh so much more than other animals? Is laughter actually good for your health, or is it just enjoyable? And what makes something funny in the first place? Christopher Duffy joins me to unpack the science and psychology of laughter. He’s a comedian, television writer, host of the TED podcast How to Be a Better Human, and author of Humor Me: How Laughing More Can Make You Present, Creative, Connected, and Happy (https://amzn.to/3LjKOyi).

It’s easy to assume that the big moments shape our lives — but what if tiny, seemingly meaningless choices matter just as much, or even more? A few minutes, a small decision, or a random event can quietly ripple outward in ways we never see. Brian Klaas joins me to explain how chance, chaos, and randomness shape our lives — and how understanding this can actually help you make better choices. Brian is an associate professor in global politics at University College London, a contributing writer for The Atlantic, and author of Fluke: Chance, Chaos, and Why Everything We Do Matters (https://amzn.to/3SrRj31).

Rats, insects, bees, deer, spiders — the world is full of creatures we label as “pests.” But what actually makes an animal a pest?
