Alone in a Crowded Room

From Psychology of Human Nature · 8:34

Show by Michel Black

You are at a party. The room is full. Music, conversation, laughter. And you feel alone. Michel follows loneliness from its definition — the gap between the relationships you want and the relationships you have — to the cycle it builds, and to the finding that more contact is often not the cure. What was observed? Loneliness is about feeling alone, not being alone; you can be lonely in a crowd and content on your own. How was it measured? The work of Cacioppo and Hawkley on perceived isolation and hypervigilance, the mortality meta-analysis of Holt-Lunstad et al. (2015) covering seventy studies and more than three million people, and the intervention meta-analysis of Masi et al. (2011). Why is it important? Loneliness is associated with a twenty-six percent increase in the odds of premature death, and it builds a self-fulfilling cycle of threat, withdrawal and more loneliness. What explanations are supported? Perceived isolation triggers hypervigilance for social threat, which biases attention and memory and drives withdrawal. What remains unknown? How far the cognitive interventions that work in trials can be made routine in everyday life, outside a clinical setting.
