**Why Educational Networks Matter?
David Aaron Newman Attewell challenge conventional accounts that treat education as an individual trait—skill, value formation, or selection—by asking how education works as a feature of social networks. Building on cleavage theory, the authors argue that educationally segregated ties can stabilize contemporary political cleavages even as traditional mass organizations wane.
What the Authors Did
Using original cross-national surveys from Germany, the United Kingdom, and Switzerland, Attewell measures respondents' educational level and field alongside the composition of their social networks and political outcomes. The analysis focuses on vote preferences and indicators of social closure (for example, group identity and bounded social circles) rather than treating individuals as isolated units.
How the Study Was Designed
- Comparative survey design covering three Western European democracies.
- Key variables: educational level and field, network composition (degree of exposure to people with different education), vote preference, and measures of social closure/group identity.
- Analytical strategy centers on whether the presence of cross-educational ties (countervailing networks) reduces the political divisions associated with education.
Key Findings
- Educational divides in political outcomes are not fixed at the individual level: they are attenuated when people have countervailing social ties that bridge educational groups.
- Segregated social networks—where people primarily interact with others of similar educational backgrounds—contribute to the persistence and stabilization of contemporary cleavages.
- These effects appear across both vote choice and measures of social closure, suggesting that network structure helps reproduce political alignment along educational lines even as party and mass organizations decline.
What This Means for Cleavage Theory and Politics
The study reframes the 'education gap' as partly a product of social structure: education matters not only for individual attributes but for who people interact with. By showing that cross-educational networks weaken, and segregated networks strengthen, education-based political divides, Attewell’s findings point to network integration as a potential lever for reducing durable political polarization tied to education.
