In this episode of the Curiosity Podcast, Nick Winnenberg sits down with Dr. Harry Taylor Owen, a social work scholar whose research focuses on loneliness, social isolation, and public health. What starts as a skeptical question — Is social isolation really as dangerous as smoking? — quickly turns into a deep dive into decades of research showing how chronic isolation affects the body, behavior, and long-term health. Dr. Taylor explains the biological stress mechanisms behind isolation, why loneliness isn’t the same thing as being alone, and how social isolation clusters with other risk factors like age, income, and access. The conversation also explores the role of technology and online communities, why older adults are especially vulnerable, and what individuals, communities, and institutions can actually do to rebuild connection. From grocery-store conversations to community infrastructure to chickens in nursing homes, this episode reframes loneliness not as a personal failure — but as a systems-level public health challenge. A thoughtful, evidence-based conversation about why connection matters more than we think — and what it would take to design a society that supports it. Cacioppo, John T., Louise C. Hawkley, Greg J.
