When political elites talk, citizens reply. Affective polarization through temporalorientation and intergroup emotions

Abstract

Political polarization on social media, particularly during electoral campaigns, has become a growing concern. This study aimed to assess levels of affective polarization in political communication, considering temporal orientation, delegitimizing beliefs, and intergroup emotions. Two studies were conducted: one during the Andalusian elections in Spain, and another during the Colombian presidential campaign. Tweets from candidates and X users were analyzed in both studies. Linguistic analysis was used to develop an index for measuring affective polarization in linguistic pieces. This index offers an alternative to the lack of linguistic measurement tools for psychological processes regarding political polarization. Findings showed that communicative strategies often exhibited high indicators of ingroup bias in contexts without political violence, resulting in lower polarization that increased with positive emotions and a forward-looking perspective. Conversely, in contexts of political violence, strategies shifted towards outgroup discrimination and delegitimization. Positive emotions decreased polarization in these situations, while a past focus intensified it. The study concluded that affective polarization could indicate the willingness to pursue reconciliation in violent contexts. Consequently, this research provides a map of emotions associated with polarization.

Public significance statement Two studies conducted in Spain and Colombia analyzed how political figures and users of the social network X communicate during elections. It was identified that the use of emotions can contribute to political polarization in both populations. Positive emotions can exacerbate polarization by glorifying one's group, while negative emotions can fuel polarization through attacks on opponents.
