Dr. Adam Grant sits down with Margaret Hoover to discuss the causes and consequences of loneliness, the impact of artificial intelligence on human connection, and the precarious state of modern manhood.

Grant, an organizational psychologist and professor at Wharton, breaks down the science of forming strong relationships, which he explores in his new book, “Vibe.” He explains how group dynamics and the need for belonging play into the Cornell Seven rape case–and why he would ban fraternities “in a heartbeat.”

Grant reflects on conversations with top AI executives, cautions against turning to chatbots for companionship, and calls for stricter regulation of the emerging technology. He also addresses the dangers of putting political parties above principles and proposes reforms that could shake up our unhealthy political culture.

Sen. Thom Tillis (R-NC) takes on the “sycophants” in the second Trump administration and reflects on his regrets over voting to confirm some of them–particularly Defense Secretary Pete Hegseth, who he is now working to get out of the Pentagon.

As he prepares to retire from the Senate in January, Tillis has released a new book, “How to Lose Friends and Antagonize Presidents.” He explains why he believes Trump’s legacy and the GOP’s future are inextricably linked, and how that leads him to defend Trump even when the president abandons conservative principles.

Tillis discusses the risk he sees if Trump refuses to accept midterm losses, the corruption investigations a Democratic Congress might launch, and why he thinks Xi Jinping is more powerful than Trump.

Shake Shack founder Danny Meyer tells Firing Line how a hot dog cart became a global brand—and why some of his biggest failures taught him the most about business.

The restaurateur explains the philosophy behind “enlightened hospitality,” why he puts employees before customers, and what closing his first restaurant taught him about failure. He also reveals why his experiment to eliminate tipping collapsed—and why America’s tipping explosion has gone too far.

Meyer recalls his complicated relationship with Anthony Bourdain, weighs in on Zohran Mamdani’s first year as New York City mayor, influencer culture and AI in restaurants, and reflects on four decades spent endeavoring to make guests feel welcome.
