Why do we replay cryptic emails, small workplace slights, and past business decisions over and over in our heads? Science journalist Donna Jackson Nakazawa has looked deep into the research and discovered the hidden brain mechanisms that get us into these loops. She explains why a need for achievement, as well as modern work culture, make the problem worse. And she shares practical techniques for recognizing when reflection has crossed into rumination, interrupting destructive thought patterns, and helping teams create more psychological clarity and safety. Nakazawa is author of “Mind Drama: The Science of Rumination and How to Outwit Your Inner Defeatist”.

Why do so many organizational change efforts stall or flat out fail? Julia Dhar, managing director and partner at Boston Consulting Group, says the problem often isn’t strategy, it’s behavior. Leaders spend enormous time designing change, but far less understanding whether employees are willing, motivated, and equipped to adopt it. She shares research around how leaders can create genuine alignment, and what it takes to sustain momentum once the novelty fades. Dhar is coauthor, along with Kristy Ellmer and Philip Jameson, of the book "How Change Really Works: Seven Science-Based Principles for Transforming Your Organization".

What if the biggest barrier to change isn’t resistance—but the way we’ve been taught to lead? Nilofer Merchant, an author and leadership expert, says a number of habits are holding organizations of all sizes back. She walks through behaviors to adapt and not just survive but thrive in a world of continuous change, including normalizing discomfort, not overlooking your best ideas, and separating confidence from competence. Merchant wrote the book Our Best Work: Break Free from the 24 Invisible Norms That Limit Us.

Many senior leaders say they want an organization filled with psychological safety and candor, but they often act in ways that are counterproductive to that goal. Charles Duhigg, an author and researcher, has looked deeply into the secrets of good communication, and says there are specific things leaders can do to improve their relationships at work, and thus the culture of the organization. He shares practical, research-backed strategies for building teams where people feel safe to challenge ideas, raise concerns, and contribute openly, from “ostentatious listening” to structuring meetings so every voice is heard. Duhigg wrote the book Supercommunicators: How to Unlock the Secret Language of Connection.

A small percentage of teams perform exceptionally well and have fun while doing it. And the secret to their success isn't innate talent. It's the way they work together. Ron Friedman, psychologist and the founder of Superteams, Inc., has studied the data on these high-performing groups across industries and identified the key leadership behaviors that drive sustained outperformance--from asking questions people often avoid to creating continuous feedback loops. Friedman is the author of the HBR article "How to Build a Superteam That Keeps Getting Better," and the book Superteams: The Science and Secrets of High-Performing Teams.
