  • Optimism Is Now an Essential Leadership Skill

    Optimism Is Now an Essential Leadership Skill
    Oct 6 2026
    Optimism isn’t about ignoring problems or pretending everything will work out. It’s about acknowledging challenges while believing that your actions can still make a difference. Psychologist and researcher Michelle Gielan says leaders can cultivate that mindset in themselves and their teams and argues that, when they do, it creates a powerful performance advantage. Drawing on an 11-year dataset of more than 25,000 business professionals, she shares research linking optimism to higher productivity, sales, engagement, and lower burnout. She explains how leaders can use techniques like “power leads" to help teams focus on progress and possibility without losing sight of difficult realities. Gielan wrote the book Resilient Optimism: The Science of Sustaining a Positive Mindset in Tough Times and the HBR article "How Leaders Counter Pessimism in Trying Times."

  • How AI Is Changing Strategy: Rethinking What Your Business Is Designed to Do

    How AI Is Changing Strategy: Rethinking What Your Business Is Designed to Do
    Oct 8 2026
    AI is advancing so quickly that companies can’t afford to treat it as simply another productivity tool; it is fundamentally reshaping strategy. In this final episode of our special four-part series on how AI is changing leadership, Wharton professor and AI expert Ethan Mollick explains why leaders need to rethink what their organizations are designed to do—and how work gets done. He discusses how AI agents are changing the role of managers, why companies need to experiment rather than wait for proven playbooks, and how leaders can create competitive advantage when everyone has access to the same frontier models. Mollick is author of the forthcoming book Co-Existence: The Next Phase of AI.

  • Why Great Teams Don’t Need to Like Each Other

    Why Great Teams Don’t Need to Like Each Other
    Oct 13 2026
    What makes a great team? It might have less to do with whether colleagues like one another and more to do with whether they’re aligned on a shared purpose. Organizational psychologist and Wharton professor Adam Grant says leaders can build stronger connections at work, foster productive conflict, and create cultures where people feel empowered to speak up. He explains why task cohesion matters more than social cohesion, how to turn differences into a competitive advantage, and why leaders should reward people who challenge the status quo; and also shares practical ways to rethink onboarding, encourage candid feedback, and help employees connect their work to a meaningful mission. Grant is the author of the new book Vibe: The Secrets of Strong Connection in a Lonely World.
