Groundbreaking Study Reveals Physical Interactions Outperform Digital Networks

Real-world social encounters predict voting patterns with significantly greater accuracy than online social networks or residential proximity, according to a new study published in PNAS Nexus. The research, conducted by Michele Tizzoni and colleagues, analyzed massive-scale co-location data from Meta’s Data for Good program, which collects anonymized location information from Facebook users who enabled location services.

Methodology: Mapping Physical Encounters and Political Behavior

Researchers defined co-location as two people being within the same map tile—areas measuring less than 600×600 meters, varying by latitude. The report states that political affiliation was inferred from participants’ county of residence, a commonly used proxy in demographic research.

This physical interaction data was compared against multiple other factors, including Facebook friendships and residential proximity measurements. For the residential analysis, sources indicate researchers examined voter registrations of the closest 1,000 neighbors to each participant. The study also incorporated individual survey responses from 2,420 Americans regarding their social networks during the 2020 presidential election.

Stark Contrast in Predictive Power

The findings reveal dramatic differences in how effectively various social connections predict voting behavior. According to the analysis, partisan exposure through physical co-location—measured by people sharing the same map tile for at least five minutes—explained 97% of the variance in county-level voting patterns.

This substantially outperformed both online connections, which accounted for 85%-87% of variance, and residential proximity, which explained only 75%-80%. Analysts suggest these results indicate that brief, incidental physical encounters may provide more meaningful political exposure than sustained digital connections or neighborhood characteristics.

Individual-Level Analysis Confirms Offline Dominance

At the individual level, data from the 2020-2022 Social Media Study conducted by the American National Election Studies showed similar patterns. The report states that offline social ties demonstrated stronger effects on actual voter choice than online connections, reinforcing the county-level findings.

Researchers also found that partisan segregation was more pronounced in physical spaces than online environments. Educational attainment appeared to structure this segregation to a large extent, suggesting that real-world social sorting along political lines may be more complex than previously understood.

Implications for Understanding Political Behavior

According to the authors, these findings highlight the fundamental importance of real-world social interactions in shaping political behavior. While digital platforms often receive blame for political polarization, the research suggests that physical-world phenomena may play an equally important, if not greater, role.

The study challenges conventional wisdom about the internet’s role in political partisanship and indicates that efforts to understand and address political division must consider both online and offline social dynamics. Sources indicate that the research provides some of the most comprehensive evidence to date about the relative importance of different social networks in political behavior.

As political analysts continue to examine the drivers of voting patterns, this research suggests that traditional face-to-face interactions remain powerfully predictive, even in an increasingly digital age. The methodology, leveraging large-scale co-location data, reportedly opens new possibilities for understanding how physical encounters shape social and political outcomes.
