What the study found
The study found that network embeddings, which are numerical representations of a person's position in a network, could predict right-wing populist voting above chance, but they were less accurate than individual characteristics. After making the embeddings more sparse and orthogonal, one embedding dimension was strongly associated with the voting outcome.
Why the authors say this matters
The authors conclude that the study shows how population-scale network embeddings can be made interpretable. They also say the findings link structural differences in education to right-wing populist voting.
What the researchers tested
The researchers created embeddings for all people in the Dutch population using a population-scale network built from five shared social contexts: neighborhood, work, family, household, and school. They then used these embeddings to predict right-wing populist voting and compared their performance with individual characteristics.
What worked and what didn't
Embeddings alone predicted right-wing populist voting above chance level. They performed worse than individual characteristics, and combining the best subset of embeddings with individual characteristics only slightly improved prediction. After transformation, one embedding dimension was strongly associated with the outcome, and mapping it back to the network showed differences in educational ties and attainment aligned with distinct network structures.
What to keep in mind
The abstract does not describe detailed limitations. The reported findings are based on the Dutch population and on prediction of right-wing populist voting using the specific network contexts and methods described.
