Political Polarization and Noisein Spain's Investiture Debates (2000–2023)

Palavras-chave: Political polarization, Ideological polarization, Affective polarization, Parliamentary discourse, Investiture debates

Resumo

This research analyzes political polarization in Spain between 2000 and 2023 through the examination of investiture debate speeches. Combining manual coding with automated text analysis in Python, 83 speeches were examined to track patterns of ideological and affective polarization across the shift from bipartisanship to a fragmented multi-party system. The findings show a sustained increase in ideological distance and emotional hostility, particularly after 2015, with leaders using more adversarial language and emphasizing ingroup unity. The analysis concludes that parliamentary discourse has become markedly more polarized, with a decline in conciliatory language and reduced opportunities for cross-party agreement.
