The Lonely Path to Violence — Understanding the Loneliness Epidemic and Political Radicalization

Today, Jen & Carolyn are diving into something that is often framed as a private pain but may actually be one of the most significant public health and political threats of our time: loneliness. And not loneliness as a vibe. Not “I wish I had brunch plans.” We’re talking about chronic social isolation — the kind that alters brain chemistry, distorts threat perception, and erodes a person’s sense of meaning and belonging. Because when we look at patterns of sexual violence, mass shootings, and certain forms of political extremism, we repeatedly see a profile emerge — socially isolated men, often young, often experiencing status loss, romantic rejection, economic precarity, or humiliation.
