Not Alone: Building Community Resilience When the World Feels Hostile

Individual coping strategies matter, but research is clear: community belonging is the most powerful resilience factor of all.

In the weeks after October 7, 2023, something happened in Jewish communities around the world that mental health researchers have long understood but struggle to adequately quantify: people turned toward each other. Shules and community centres that had been quietly struggling with attendance numbers were suddenly full. Community phone trees activated. WhatsApp groups swelled. People who had not identified strongly as part of a community found themselves seeking one.

This instinct — to gather in the face of threat — is not merely cultural. It is deeply biological. Social belonging is one of the most fundamental human needs, and the capacity of community connection to buffer individuals against the psychological effects of trauma and threat is among the most robustly demonstrated findings in the entire field of mental health research. The Science of Belonging as Medicine

Professor Julianne Holt-Lunstad of Brigham Young University, whose landmark meta-analyses of social connection and health outcomes have had significant influence on public health policy, has described social isolation as carrying a mortality risk comparable to smoking fifteen cigarettes a day. Her research, along with a substantial body of work by colleagues including Robert Waldinger of Harvard, demonstrates that social connection is not a comfort — it is a biological necessity whose absence causes measurable physiological harm.

For groups under stress, the mechanisms are particularly relevant. Research on community-level resilience following collective trauma — including studies of communities that have experienced terrorist attacks, natural disasters, and persistent discrimination — consistently identifies social cohesion as the primary protective factor. Communities where people know each other, trust each other, and have established patterns of mutual support not only recover faster from acute events; they show lower rates of anxiety and depression in their members during periods of sustained threat.

For Jewish communities, this research has a particular resonance. The traditions, practices, and institutions that have sustained Jewish life through millennia of adversity can be understood, in part, as a sophisticated community resilience infrastructure. Shabbat and festival cycles that create regular rhythms of gathering; mourning practices that embed the bereaved in community; lifecycle celebrations that mark individual milestones as communal occasions; charitable structures that create interdependence — these are not incidental features of Jewish life. They are, whether their designers knew it or not, evidence-based mental health interventions at scale.
