The Quantity and the Quality of Party Systems
Abstract
Previous research claims that the number of parties affects the representation of social cleavages in voting behavior, election turnout, patterns of political conflict, and other party system effects. This article argues that research typically counts the quantity of parties and that often the more important property is the quality of party competition—the polarization of political parties within a party system. The author first discusses why polarization is important to study. Second, the author provides a new measurement of party system polarization based on voter perceptions of party positions in the Comparative Study of Electoral Systems, which includes more than 50 separate elections from established and developing democracies. Third, the author compares party polarization and party fractionalization as influences on cleavage-based and ideological voting and as predictors of turnout levels. The finding is that party polarization is empirically more important in explaining these outcomes.

Simón y Rodríguez-Teruel utilizan el índice de polarización de Dalton, al igual que nosotros.
“Al igual que nosotros, utilizan el índice de polarización de Dalton, aunque los resultados que obtienen son diferentes a los nuestros, debido principalmente a nuestro ajuste del modelo y a la diferencia en el periodo analizado.”

La decisión de Dalton de usar un divisor de cinco está motivada por el hecho de que en la encuesta que utilizó, la ubicación de los partidos se medía en una escala de 0 a 10, por lo que 5 era el valor medio, ya que había una diferencia de cinco puntos entre cada polo y el medio.

Dalton (2008) establece un divisor de cinco para asegurar que el índice devuelve 0 cuando no hay polarización y 10 en el caso de polarización absoluta.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
