Chapter 1: How does social connection influence human behavior?
So we're sensitive to signals of potential rejection or actual rejection because it then motivates a bunch of useful behaviors to help us reconnect either with the person if we've done something that causes harm or with other people if we've been excluded or rejected.
Welcome to Passion Struck. Hi, I'm your host, John R. Miles. And on the show, we decipher the secrets, tips, and guidance of the world's most inspiring people and turn their wisdom into practical advice for you and those around you. Our mission is to help you unlock the power of intentionality so that you can become the best version of yourself.
If you're new to the show, I offer advice and answer listener questions on Fridays. We have long-form interviews the rest of the week with guests ranging from astronauts to authors, CEOs, creators, innovators, scientists, military leaders, visionaries, and athletes. Now, let's go out there and become passion struck. Hey, passion struck fam, welcome to episode 596.
Whether you've been with us for a while or you're joining us for the first time, thank you so much for being here. You're now part of a global community of changemakers committed to living with purpose, leading with intention, and igniting a life that truly matters. Let me ask you this. Why do we share the things we do?
Why do some ideas spread like wildfire while others fall flat, no matter how important they are? And what if the key to lasting behavioral change isn't more willpower, but understanding how the brain assigns value? That's exactly what today's guest, Dr. Emily Falk, explores in her groundbreaking new book, What We Value, The Neuroscience of Choice and Change.
Emily is a pioneering neuroscientist at the University of Pennsylvania. She's also the Vice Dean of the Annenberg School of Communication, Director of the Communication Neuroscience Lab, and leads the Climate Communication Division at the Annenberg Public Policy Center. Her work sits at the intersection of psychology, communication, and the science of change.
In this fascinating conversation, we dive into the hidden processes that shape our decisions, how self-relevance and social connection influence everything we share, and what it really takes to inspire change from individual habits to global movements. Emily's insights are essential for anyone who wants to understand, influence,
improve communication, and create messages that move people, not just in theory, but in the real world. We also explore how small acts of sharing are foundational to human connection, how algorithms and culture shape our values and attention, what neuroscience teaches us about motivation, empathy, and identity, and how to align what we value with the change we want to create.
But before we dive in, let's reflect on my episode earlier this week. On Tuesday, I was joined with Humble the Poet to unpack one of the most widespread and misunderstood emotional experiences of our time, anxiety. It's an unfiltered look at identity, self-worth, and finding calm in a chaotic world.

Chapter 2: Why is understanding brain's value calculation vital for decision making?
But you were asking me about what does this tell us about the speed of our decisions? And what I think Jenny really highlighted when she told the story was about the ways that the people trying to be helpful can be exploited for these other kinds of means. And as we think about our own experiences as individuals, like think about interacting on the internet, most people.
in the world are kind and good. And often when you read news, it's by journalists who are very dedicated to hunting down the truth, but our tendencies, our natural tendencies can also be exploited to sell us false information or to have us fall prey to bots or other folks who don't have our best interests at heart. Right.
I will also say in terms of your past experience that you were describing, I'm married to a cryptographer.
Well, there you go.
Privacy and data security are salient in my mind as well.
Oh, it also made me think of how does our perception of others values, especially in not only the environment you talked about on the web, but in social media environments, distort the choices that we make about who we are and how we show up.
I think so much evidence that what we think other people's preferences and behaviors are shape ours. So our social relevance system helps us understand what other people are thinking and feeling. And what other people are thinking and feeling influences our value calculation.
So there've been a number of brain imaging studies that have looked at, for example, when people look at photographs of other people's faces, we might think that we have our own unique tastes and preferences.
Like for example, that when we fall in love, it's really unique, but scientists have shown that when people are given information about who other people think are more or less attractive, that shapes
