And why are some things so incredibly hard to stop? Psychotherapist Talitha Fosh explains what really makes us get hooked and what it takes to break free. She is author of Hooked: Why We Are Addicted and How to Break Free (https://amzn.to/3XDW8sq).

Before you trust an airplane, a child’s toy or just about anything else, it has probably been subjected to some serious testing—and some of those tests get wonderfully weird. Engineers have fired chickens into jet engines and enlisted real bears to test bear-proof containers. Alex Davies takes us inside this strange, mostly invisible world of product testing. He is a senior editor at Amazon and author of Kobuk the Destroyer: And Other Tales from the Wild, Unseen World of Test Engineering (https://amzn.to/3UR4YEg).

Criticism can really sting, rejection can linger, and an offhand remark can hit surprisingly hard. Why are some people wired this way, and is it something they need to change? Psychiatrist Dr. Sasha Hamdani explains the science of sensitivity, rejection and resilience. She is author of Too Sensitive: Rejection, Resilience, and the Science of Feeling Deeply (https://amzn.to/4c9bgFn).

Why do you believe some people almost immediately, while others make you skeptical? You might assume credibility comes down to expertise, experience and having the facts on your side. But there is much more going on. Research shows that we respond to subtle signals that can make someone seem more believable — sometimes before we’ve really considered what they’re saying.

Even more surprising, some of the things people do to appear credible can actually make them less convincing. And many of the signals that influence us have little to do with the actual message.

Understanding this matters more than ever. Every day we have to decide which experts, politicians, salespeople, coworkers, influencers and strangers we should believe — and which ones we shouldn’t.

Stephen Martin is a visiting professor of behavioral science at Columbia University and an expert on influence and persuasion. He is co-author of Messengers: Who We Listen To, Who We Don’t, and Why (https://amzn.to/2MDAtej). He joins me to explain the surprisingly subtle characteristics that make people seem credible, why they work on us, and how understanding them can help you become more persuasive — and a little harder to fool.

Have you ever been completely stuck trying to solve a problem or come up with a new idea? There is a remarkably simple thing you can do that research shows can get your creative juices flowing. And it works surprisingly well. https://news.stanford.edu/stories/2014/04/walking-vs-sitting-042414

Can you actually think yourself sick? Absolutely. It’s called the nocebo effect — essentially the evil twin of the placebo effect. If a doctor warns you that a medication might cause certain side effects, simply hearing that can make those symptoms more likely to occur. The same thing can happen when you read about an illness or medication online. Your expectations can trigger very real physical symptoms. So how does that happen — and how do you protect yourself from it? Helen Pilcher is a science writer with a PhD in neuroscience from London’s Institute of Psychiatry, and she has some remarkable examples of the nocebo effect in action. She is author of This Book May Cause Side Effects: The Curious and Dangerous Power of the Nocebo Effect, Placebo’s Evil Twin (https://amzn.to/4qvrdLU).

Why are sideburns called sideburns? How could the first automatic door possibly have been invented before the birth of Christ? And where in the world did the word dude come from?

Eye contact can be tricky. Too little can make you seem bored or distracted. Too much can get uncomfortable fast. So what is the right amount? This episode begins with some fascinating research on eye contact and the subtle signals you send with your eyes. http://www.spring.org.uk/2013/07/how-eye-contact-works.php

Someone tells you a secret and makes you promise not to tell. You intend to keep that promise — so why can the urge to tell someone else become so strong? Secrets can weigh on us, yet revealing one can damage relationships and destroy trust. So which secrets do we keep, which do we tell and who do we tell them to? Andrew Gold is an investigative journalist, podcaster and filmmaker who has made documentaries for the BBC and HBO. He is author of The Psychology of Secrets: My Adventures with Murderers, Cults and Influencers (https://amzn.to/3MiwXoS). Listen as he explores why keeping something to yourself can be surprisingly difficult.

Why is the alphabet in the order ABCDE? Why do we have uppercase and lowercase letters? What’s the dot over a lowercase i and j for? And why do we capitalize I? Behind many of the oddities of English are some wonderful stories. Linguist Paul Anthony Jones joins me to explain how some of the strangest features of our language got that way. He has a popular YouTube channel devoted to language and is author of Why Is This a Question?: Everything About the Origins and Oddities of Language You Never Thought to Ask (https://amzn.to/3Z0Nrtm).
