About this episode

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? Those are just a few of the strange facts and curious word origins explored by Jess Zafarris. She joins me to reveal some fascinating bits of history and language that will leave you with plenty of things you never knew you wanted to know. Jess is co-author of A Miscellany of Weird and Wonderful Facts for Curious Humans Who Have Nothing Better to Do Than Read (https://amzn.to/4wFtLZq). When you say something embarrassing, have a bad hair day or just feel awkward in a group, it can seem as if everyone notices. But how closely are other people really paying attention to you? Psychologists have studied this, and what they discovered should make your next embarrassing moment a little easier to handle. https://www.psychologytoday.com/us/articles/199612/why-bad-hair-days-may-not-matter PLEASE SUPPORT OUR SPONSORS MONARCH: Write your own money story with Monarch!
