The strongest argument for community-building is a medical one.
In 2010, Julianne Holt-Lunstad and colleagues published a meta-analysis in PLOS Medicine pooling 148 studies and more than 308,000 people. People with stronger social relationships had a 50 percent higher likelihood of survival over the study periods. The effect held across age, sex, and initial health. The authors noted its magnitude is comparable to quitting smoking, and larger than the mortality risk of obesity or physical inactivity.
In 2023, the U.S. Surgeon General issued a formal advisory calling loneliness and isolation an epidemic, treating weak social connection as a public-health problem on the order of tobacco. The framing there matters: connection counts as a determinant of health, something institutions can be held responsible for.
That reframes what a festival, a workshop, or a community space actually produces. When these places reduce isolation, they are doing measurable health work — not metaphorically, but in the same category as the risk factors a doctor screens for.
The design question is how you build connection that lasts. Here the evidence favors making over talking. In the cortisol research from Drexel, the benefit came from absorbed, hands-on activity. In practice, a shared creative task lowers the social cost of connection: hands are busy, silence is comfortable, and the thing on the table gives two strangers a reason to talk that neither had to manufacture. Making asks less of people than conversation and tends to give more back.
This is the thesis under Creative Belonging and under most of the work I do: you create your way out of loneliness. The research does not prove that any single program cures isolation — these are population-level and short-term findings, and they should be cited as evidence, not as a promise. But taken together they support a clear claim. Belonging belongs on the list of things a community measures and invests in, next to clean air and safe streets.
