In this episode we welcome psychologist Mary C. Murphy, author of Cultures of Growth, who tells us how to create institutions, businesses, and other groups of humans that can better support collaboration, innovation, performance, and wellbeing. We also learn how, even if you know all about the growth mindset, the latest research suggests you not may not be creating a culture of growth despite what feels like your best efforts to do so.

In 1974, two psychologists, Daniel Kahneman and Amos Tversky, as the New Yorker once put it, “changed the way we think about the way we think.” Before their landmark research went viral (in the way things went viral in the 1970s), the prevailing wisdom was that human beings were, for the most part, rational optimizers always making the kinds of judgments and decisions that best maximized the potential of the outcomes under their control. This was especially true in economics at the time. The story of how they generated a paradigm shift so powerful that it reached far outside economics and psychology to change the way all of us see ourselves is a fascinating tale, one that required the invention of something this episode is all about: The Psychology of Single Questions.

Jeremy Utley, Kian Gohar, and Henrik Werdelin sit down with David McRaney to discuss the surprising results of a new study into what happens when groups of people work together to brainstorm solutions to problems with the help of ChatGPT. It turns out, a common cognitive bias makes it difficult to produce a steady stream of great ideas. Based on their research, Utley and Gohar created a new paradigm for getting the most out of AI-assisted ideation which they call FIXIT, and you’ll hear all about it in the episode.

Our guest in this episode is Charles Duhigg, a Pulitzer Prize winning journalist and writer for the New Yorker Magazine who is also the New York Times Bestselling author of The Power of Habit and Smarter Faster Better. His new book is Supercommunicators, a practical and approachable guide to what makes great conversations work. We discuss the science behind what it takes to form a connection with another human being, how to generate or nurture a bond through dialogue, and how to form, repair, and maintain a conversational pipeline – through listening and communicating –that guarantees reciprocation and understanding.

Have you ever been in a classroom or a business meeting or a conference  and had a question or been confused by the presentation, and when the person running the show asked, “Does anyone have any questions?” or, “Does anyone not understand?” or, “Is anyone confused?” you looked around, saw no one else raising their hands, and then chose to pass on the opportunity to clear up your confusion?

If so, then, first of all, you are a normal, fully functioning human being with a normal, fully functioning brain, because not only is this common and predictable, there’s a psychological term for why most people don’t speak up in situations like these. It’s called pluralistic ignorance.

On this episode we learn about the history of the exclamation point, the question mark, and the semicolon (among many other aspects of language) with Florence Hazrat, a scholar of punctuation, who, to my great surprise, informed me that while a lot of language is the result of a slow evolution, a gradual ever-changing process, punctuation in the English language is often an exception to this – for instance, a single person invented the semicolon; they woke up and the semicolon didn’t exist, and then went to bed that night, and it did!
