Something You Should Know

Everyone seems more stressed than ever — and oddly, some people even wear it like a badge of honor. But chronic stress isn’t something to brag about. It quietly alters the way you think. It amplifies worry, exaggerates threats, narrows your options, and makes worst-case scenarios feel not just possible, but probable. Over time, stress doesn’t just affect your mood — it reshapes your perception, your judgment, and the decisions you make. And because the shift happens gradually, you often don’t realize it’s happening at all. Clinical psychologist Arthur Ciaramicoli has spent decades studying stress and its impact on the brain and behavior. In this conversation, he explains what’s actually happening neurologically when stress rises — how your brain shifts into a more reactive mode, why you become more negative and less flexible in your thinking, and how chronic stress can trap you in a self-reinforcing loop. We also explore why modern life seems perfectly designed to keep stress levels elevated and why simply

When a big storm is on the way, it happens like clockwork: empty shelves, frantic shoppers, and a sudden shortage of eggs, bread, and milk. Why do people panic-buy the same items every time? And how much do you actually need if you’re stuck at home for a few days? This episode begins with the psychology behind panic shopping — and why otherwise rational people behave this way. https://www.psychologytoday.com/us/blog/happy-trails/201601/panic-shopping-the-psychology-of-the-bread-milk-eggs-rush Most of us don’t think of ourselves as vulnerable. We assume danger happens to other people — until it doesn’t. In reality, small, everyday behaviors can quietly increase or reduce your personal safety. The way you speak, move, and pay attention sends signals you may not even realize you’re broadcasting. Dannah Eve joins me to explain how street smarts really work and how to protect yourself using simple, practical awareness. She’s a personal safety educator and author of Street Smarts: Trust Your Instincts, Outsmart Da

Are women really attracted to men who can make them laugh? And if so, why does humor matter so much in attraction? This episode begins with what research and relationship experts say about laughter, mating, and why being funny can be a powerful social signal. https://amzn.to/496hAtL We’ve always been fascinated by twins. They seem mysterious, almost magical — as if they share a special connection the rest of us don’t. But do twins really experience the world differently, or are we projecting myths onto them? Helena de Bres joins me to unpack the truths, misconceptions, and lived reality of being a twin. She’s a professor of philosophy at Wellesley College and author of How to Be Multiple: The Philosophy of Twins (https://amzn.to/3HCmH8E). Most financial advice sounds the same: save more, spend less, invest wisely. But some of the most effective money guidance runs counter to what we usually hear. Vivian Tu shares a fresh, practical perspective on money, habits, and mindset — including mistakes people make

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

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).

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

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

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).

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 p

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.

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

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

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 physical

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.

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 Cha

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).

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 th

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).
