“When We, Not Them”: How Scientists Help Cities Bridge Polarization

The Revelation of Moscow: When Politics Gives Way to Balconies

In Moscow, a drab Soviet-era residential district faces demolition. By common logic, the residents here would be two截然不同 types of people on the political spectrum – some support the government, others oppose it. But when the bulldozers approached, they made a surprising choice: Set aside all political differences and jointly defend their homes. They wrote letters, marched, and negotiated with developers together. At that moment, "we" became the defenders, and "they" became the outsiders.

Sociologist Anna Zhelnina documented this scene in 2022. She found that shared material interests – such as keeping a house, a familiar street corner, a neighborhood memory – could easily penetrate the walls of ideology. This is not an isolated case; similar stories are unfolding all over the world.

From Abstract to Concrete: How Proximity Softens Opposition

In Canada, political scientist Jack Lucas of the University of Calgary and his team conducted a large-scale survey of 4,000 residents who identify as "left" or "right." They asked people whether they support typical policies: for example, "establishing car-free zones" (usually supported by the left) and "installing more security cameras" (usually supported by the right). The answers were unsurprising: people largely fell in line with their ideology.

However, when the question was rephrased in a more "personalized" way – for example, "My municipality should install more security cameras" – support among left-leaning residents rose significantly, and right-leaning residents were not necessarily opposed. The prefix "my community" acted like a key, opening a door that should have been tightly locked. Lucas says this reveals a familiar paradox of urban life: people may support building more affordable housing, but oppose it being built next to their own home; people might hate bureaucracy, but when a new project is planned in their backyard, they long for someone to step in.

Public Space: The Most Rudimentary Laboratory of Integration

These studies point to a simple truth: When an issue is close enough to home, ideological purity wanes. Public spaces in cities – cafes, parks, community gardens, farmers' markets – are natural stages for this "proximity." Here, people must face real individuals, not labels. A right-leaning neighbor who fiercely debates immigration policy on social media might stand shoulder to shoulder with a left-leaning mother on community safety issues, simply because their children play together in the same sandpit.Scientists—especially political scientists, sociologists, and psychologists—have recognized this. They are no longer content to merely study how division occurs; they have begun designing interventions to help people re-establish the perception of "us." For example, psychologists Sabina Čehajić-Clancy and Eran Halperin wrote in Nature Reviews Psychology that the key to reducing polarization is finding a shared identity, which often starts with concrete, localized cooperation. Cleaning a park together, organizing a block party, protesting an unreasonable plan—these small collective actions are the thread that heals social rifts.

Lifestyle Advice: Embrace Your Neighborhood

For ordinary people living in cities, the implication of this research is not complicated: Don't live solely in abstract debates; engage in the concrete matters around you. The next community meeting, neighborhood cleanup day, or block dinner might change your view of "them" more than any online argument. Scientists' toolkit is growing, and our daily choices are the best experimental grounds.

When "we" are not "them" but rather the neighbor who jointly guards the balcony, sweeps the street, and advocates for security cameras, the city can truly become everyone's home.
