Have you ever noticed that when two people walk together, they often fall into step without even trying? Or that people in conversation sometimes begin to mirror each other’s movements? Humans have a curious tendency to synchronize with one another, often without realizing it. Why does this happen, and what does it reveal about how we connect? https://www.caltech.edu/about/news/social-synchronicity-37695
You’ve heard all your life that reading is good for you. It expands your vocabulary, sharpens your mind, and makes you more knowledgeable. But reading fiction may do something remarkable that other kinds of reading don’t. There is something about the way fiction is written and the way our brains respond to it that produces some surprising benefits. Even the simple words “Once upon a time” can trigger something special. Andrew Piper, professor at McGill University and author of Why You Should Read More Fiction: What Data and AI Tell Us About the Value of Storytelling (https://link.amazon/B01VixDmx), joins me to explain what fascinating new research reveals about the power of fiction — and why picking up a novel may be one of the best things you can do for yourself.
We’ve all heard the warning about “groupthink” — that putting people together to solve a problem can sometimes produce worse results than letting them work alone. But what if the problem isn’t collaboration itself, but how we collaborate? Research into collective intelligence reveals that under the right conditions, groups can become remarkably good at solving problems, generating ideas, and making decisions. The trick is knowing how to bring people together so their combined intelligence actually works. Damon Centola, professor of Communication, Sociology, and Engineering at the University of Pennsylvania, studies how this happens. He is also the author of Goodthink: The New Science of Collective Intelligence (https://link.amazon/B05J8lAqo). Listen as he explains what makes some groups smarter than others and how we can use this science to work better together.
Why does time seem to speed up as we get older? You look back and wonder where the summer went, or how five years could have passed so quickly. Interestingly, research suggests that time doesn’t necessarily feel faster while we’re living it. It’s when we look back that things seem to have flown by. So what’s going on in our brains that creates this illusion? And is there a way to make life feel like it’s moving a little more slowly? https://link.springer.com/article/10.3758/s13423-025-02833-z
