How Contextual Features Shape Incivility Over Time: An Analysis of the Evolution and Determinants of Political Incivility in Televised Election Debates (1985–2019)

Abstract

Concerns are frequently raised about politicians’ increasing use of incivility. Yet, there is little longitudinal empirical work testing whether politicians’ use of incivility is actually rising, and little is known about the determinants that affect the prevalence of incivility. This study analyzes incivility over time and proposes a multi-layered framework of theoretically-driven incivility-inducing determinants. A quantitative content analysis of 4,102 speech acts in 24 Belgian televised election debates over the course of 35 years (1985–2019) shows that politicians’ incivility did not increase but occurs in a volatile pattern with ups and downs over the years. Confirmed by our analysis of the studied determinants, incivility shows to be highly context-specific. Particularly, incivility levels are affected both by characteristics of politicians, such as populism, incumbency, and gender, and by debate determinants, such as the topic under discussion, the number of politicians simultaneously debating each other, and previous incivility occurrences in the debate.
