Special Issue: Affective Polarization in Multiparty Systems: Conceptualization, Causes and Consequences
Bibliographic record
Abstract
Understanding affective polarization is central to the study of contemporary democracies. In addition to their ideological differences, voters increasingly perceive other party supporters as members of rival outgroups. In spite of the long tradition of USA-based research, we are still at the beginning of our study of affective polarization in multiparty systems. This proposed special issue presents a set of studies of the conceptualization, measurement, causes and consequences of affective polarization in multiparty democracies in Europe and beyond. A comprehensive investigation of affective polarization in a diverse and inherently comparative setting is a significant step forward. The studies place their emphasis on different aspects of affective polarization and use a variety of rigorous methodological approaches, thus advancing research on the study of affective polarization beyond the United States. We expect this special issue to receive broad attention from scholars in political science and beyond.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
