Something You Should Know

Ask frequent flyers what bothers them most about air travel and you might be surprised by the answer. It’s not turbulence, cramped seats, or bad food — it’s the other passengers. This episode begins by revealing which behaviors irritate fellow travelers the most and what people wish would stop happening at 35,000 feet. https://pro.morningconsult.com/analysis/airplane-etiquette-annoying-behaviors What brings two people together romantically has always been a mystery — and today, it’s more complicated than ever. Dating apps offer endless options, yet many people struggle to find meaningful connection. What actually predicts long-term attraction? What matters less than we think? And what do science and history tell us about love, choice, and compatibility? Paul Eastwick joins me to explain how attraction really works. He’s a professor of psychology at the University of California, Davis, director of the Attraction and Relationships Research Laboratory, and author of Bonded by Evolution: The New Science of Love and Connection (https://amzn.to/49RrGS0) Most people pursue goals with a clear payoff — something they hope and expect to achieve. But some people dedicate their lives to goals they know will never happen. Why would anyone do that? What sustains them? And what do these impossible pursuits reveal about meaning, purpose, and fulfillment? Journalist Mark Medley shares remarkable stories of people chasing futures they’ll never live to see. He’s author of Live to See the Day: Impossible Goals, Unimaginable Futures, and the Pursuit of Things That May Never Be (https://amzn.to/46fV95J). And finally, think about all the surfaces your phone touches — tables, counters, public spaces. Then think about where that phone goes when it rings – your face. We wrap up with what science says about phones, germs, and what that means for your skin and health.https://timesofindia.indiatimes.com/life-style/beauty/how-smartphones-damage-your-skin-5-ways-to-protect-against-blue-light-and-bacteria/articleshow/124968775.cms PLEASE SUPPORT OUR SPONSORS QUINCE: Refresh your wardrobe with Quince!

Why would anyone need to be taught how to sleep, breathe, or drink water? Those are things you already do every day. And yet, it turns out most of us are doing them just wrong enough to undermine our health. In this SYSK Trending episode, I talk with Michael Breus, one of the world’s leading sleep experts, about how small adjustments to when and how you sleep, breathe, and hydrate can produce outsized benefits for your energy, immunity, metabolism, and long-term health. Dr. Breus is a double-board-certified clinical psychologist and sleep specialist, and the author of Sleep Drink Breathe: Simple Daily Habits for Profound Long-Term Health (https://amzn.to/3ZposzW). His research shows that better health doesn’t always require doing more—it often comes from doing the basics correctly. This is simple advice, but it’s powerful—and it may change how you think about your daily habits.

We’ve all heard the “rules” about sleep — you need exactly eight hours, falling asleep in front of the TV is bad, and you can make up for lost sleep on the weekend. But how much of that is actually true? This episode begins by separating sleep myths from sleep reality — and the answers may surprise you. https://www.thehealthy.com/sleep/sleep-facts-myths/ When it comes to building wealth, complexity is often the enemy. Many financial experts agree that the simplest strategy — saving automatically before you ever see the money — is also one of the most powerful. But how does it work in practice? How quickly does it add up? And why does automation matter so much? David Bach joins me to explain why this approach has helped millions of people grow wealth quietly and consistently. David is author of ten best-selling books, including The Automatic Millionaire (https://amzn.to/4rjqoow), recently expanded and updated. Self-doubt has a sneaky way of holding us back. It shows up right when opportunities appear, making us hesitate, second-guess, or play it safe — even when we know what we want. Where does that inner voice come from, and how do you turn it down without pretending it doesn’t exist? Shadé Zahrai offers insight into how self-doubt forms and how to build real confidence that lasts. She’s a behavioral researcher, award-winning peak-performance educator, and author of Big Trust: Rewire Self-Doubt, Find Your Confidence (https://amzn.to/49VY9GV). And finally, no matter how bug-free you think your home is, you’re not alone in it. A surprising number of tiny creatures live alongside us — and in many cases, that’s actually a good thing. We wrap up with who these unseen roommates are and why they’re part of a healthy home ecosystem. https://www.ipm.org/show/amomentofscience/2023-03-28/arthropods-in-your-house PLEASE SUPPORT OUR SPONSORS QUINCE: Refresh your wardrobe with Quince!

Human touch feels good — but it may also do far more than we realize. From a reassuring hand on the shoulder to a long hug or massage, deliberate touch can trigger measurable biological responses in the body. This episode begins with what science reveals about why touch matters and what happens when we don’t get enough of it. https://www.psychologytoday.com/us/blog/everyone-top/202108/the-vital-importance-human-touch 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). “Big Tech” companies influence how we communicate, shop, work, and even think — yet they operate with surprisingly little oversight. Who should be setting the rules for companies with that much power? And what happens if no one does? Tom Wheeler explains why tech regulation matters, what’s at stake, and who should be in charge. Tom served as Chairman of the Federal Communications Commission during the Obama administration and is author of Techlash: Who Makes the Rules in the Digital Gilded Age? (https://amzn.to/47OunPU). And finally, could what kids eat affect their risk of asthma, eczema, or other allergic conditions? Research suggests a link between fast food consumption and respiratory allergies.

There’s an art — and a surprising amount of psychology — behind giving a great compliment. When done well, flattery can strengthen relationships, build trust, and make people more receptive. When done poorly, it can feel awkward or manipulative. This episode begins with what research says about how to give and receive compliments the right way. https://www.psychologytoday.com/us/blog/evidence-based-living/202109/the-psychology-compliments-nice-word-goes-long-way Americans buy an astonishing amount of cheap stuff — souvenirs, knick-knacks, novelty items, gadgets — most of which quickly lose their appeal and end up forgotten in drawers or closets. Why are we so drawn to these things in the first place? And why do they so often disappoint us? Wendy Woloson joins me to explain the deep cultural, emotional, and historical forces behind our love of “cheap crap.” She’s an associate professor of history at Rutgers University–Camden and author of Crap: A History of Cheap Stuff in America (https://amzn.to/3M9M9WM). When it comes to health, many people may be thinking about exercise all wrong. Staying healthy isn’t just about gym workouts or formal exercise — it’s about how much you move throughout the entire day. Small movements, done consistently, can have a powerful impact on longevity and overall fitness. Juliet Starrett explains why everyday movement matters more than you think and how to easily build it into your routine. She’s co-author of Built to Move (https://amzn.to/3ZwADHH) and host of The Ready State podcast.(https://thereadystate.com/podcasts/) And finally — if you’re someone who doodles while listening, you may not be distracted at all. Research suggests doodling can actually improve focus and memory. We wrap up with why letting your pen wander may help your brain pay better attention. https://www.wsj.com/articles/the-power-of-the-doodle-improve-your-focus-and-memory-1406675744 Learn more about your ad choices.

SYSK TRENDING takes a look back at conversations from the Something You Should Know archive that connect directly to topics people are talking about right now. Motivation is one of them. We tend to think people are motivated by carrots and sticks — rewards if you do what’s expected, punishment if you don’t. And while that approach can work in some situations, research shows it’s often not the most effective way to motivate yourself or others. Daniel Pink explains what actually drives human motivation and why autonomy, mastery, and purpose matter far more than we realize. Daniel is the author of Drive: The Surprising Truth about What Motivates Us (https://amzn.to/4kn5DGs) , and in this conversation he shares practical insights you can use at work, at home, and in your own life — especially at a time when so many people are struggling to stay motivated.

You’ve probably been told to be grateful for what you have — but that advice isn’t just feel-good wisdom. Research shows that intentionally expressing gratitude can actually change how your brain functions, influencing mood, focus, and emotional resilience. This episode begins with what gratitude really does inside your head — and why it’s more powerful than it sounds. https://www.thecut.com/2016/01/how-expressing-gratitude-change-your-brain.html There’s a basic human need we rarely talk about, yet it quietly shapes how people behave: the need to matter – to feel significant. When people feel seen and valued they tend to thrive. When they don’t, the consequences can be serious — for individuals and for society. Jennifer Breheny Wallace joins me to explain why mattering is so essential and how it affects relationships, motivation, and well-being. She’s an award-winning journalist and author of Mattering: The Secret to a Life of Deep Connection and Purpose (https://amzn.to/4r0ZX6W). Cats are the second most popular pets in the United States — yet many people don’t understand the appeal at all. Cats can seem aloof, independent, and uninterested in pleasing us. So why have humans kept cats as companions for thousands of years? And what do cat lovers get from the relationship that others miss? Jerry Moore explains the long, surprising history of cats and why they continue to captivate us. He’s a professor emeritus of anthropology at California State University, Dominguez Hills, and author of Cat Tales: A History (https://amzn.to/4sUBPEU). And finally, when you’re sick with a cold or the flu, some old-fashioned home remedies actually have science on their side. They may not cure you — but they can make being sick a little less miserable. We wrap up with which remedies help and why they work.https://www.consumerreports.org/health/flu/how-to-beat-a-bad-cold-or-the-flu-a9270666041/ Learn more about your ad choices.

In almost every job interview, there’s one question that catches people off guard — not because it’s rare, but because most candidates think they already know how to answer it. They don’t. This episode begins by revealing that question and how to craft a response that instantly sets you apart. https://www.forbes.com/pictures/lml45mmjg/why-should-i-hire-you-2/?sh=4c5a502c53d8 Robots fascinate us — and that fascination may be leading us into trouble. Even when we know robots are just machines, we instinctively treat them like thinking, feeling beings. We trust them, empathize with them, and sometimes overestimate their intelligence. Eve Herold explains why this happens, the real risks it creates, and how humans can maintain control and clarity as social robots become part of everyday life. She’s an award-winning science writer and author of Robots and the People Who Love Them: Holding on to Our Humanity in an Age of Social Robots. (https://amzn.to/3ObcBzb) Most people think confidence is something you either have or you don’t — but that assumption may be the problem. According to Viv Groskop, you likely already have more confidence than you realize. The key is knowing how to access it and project it in the moments that matter most. Viv is a writer, comedian, executive coach, and author of Happy High Status: How to Effortlessly Be Confident. (https://amzn.to/3vQYj0h) And finally, an eye exam does far more than determine whether you need glasses or contacts. In many cases, it can reveal early warning signs of serious health conditions you might not otherwise detect. We wrap up with why regular eye exams are more important than most people realize. https://www.allaboutvision.com/eye-exam/cost-and-how-often/ PLEASE SUPPORT OUR SPONSORS SHOPIFY: In 2026, stop waiting and start selling with Shopify!

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 When you spend discretionary money, you probably think you know what you’re buying. But there’s another way to think about those purchases — one that research suggests can have a big impact on how satisfied and balanced you feel about spending that money.

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.

Is a newborn baby more likely to resemble mom or dad – or is it a toss-up? This episode begins by explaining why a baby is more likely to look like one parent and not the other and why that is. https://www.nytimes.com/2005/03/22/health/the-claim-babies-tend-to-look-like-their-fathers.html 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. He is also author of the book, For the Culture: The Power Behind What We Buy, What We Do, and Who We Want to Be (https://amzn.to/3tOT4On). 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) Is it ever too late to change your life or must you set your course early if you are ever to make something of yourself? Interestingly, researchers followed 350 students for decades – all the way into adulthood to see how they turned out.

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) And finally, there’s a simple way to make coffee or hot chocolate taste better — without changing the recipe. The color of your mug actually alters how your brain perceives flavor.

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. Instead, they hinge on just two essential qualities — and without them, relationships are likely doomed.

How food tastes has surprisingly little to do with the food itself. The lighting in the room, the weight of your fork, and even the color of your plate can all change how much you enjoy a meal — without you realizing it. 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).

There’s a reason hearing your mother’s voice can feel different from hearing anyone else’s — even when it’s just a phone call. This episode opens with the surprising effects researchers have discovered. https://www.psychologytoday.com/us/blog/the-psychology-of-relationships/202104/two-key-reasons-why-you-should-call-your-mom 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 Learn more about your ad choices.

When children grow up and look back on their childhood, what do they remember most about their parents? It turns out it’s not what many parents assume. 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). And finally, you’ve probably heard you should never let your gas tank drop below a quarter full — but is that really true? We wrap up by separating myth from reality and explaining when low fuel actually matters and when it doesn’t. https://www.carparts.com/blog/fact-or-myth-driving-with-less-than-a-quarter-of-a-tank-of-fuel-is-bad-for-your-car/ Learn more about your ad choices.
