All About Feelings? Emotional Appeals as Drivers of User Engagement With Facebook Posts

Abstract

Political campaigns routinely appeal to citizens’ emotions, and there is evidence that such appeals influence political behaviour. Social media, an important arena through which political actors communicate with voters, provide a rich source of data for investigating not only which communication strategies they use but also which of these engage followers. Building on political psychology and political communication literature, the present study investigates the relationship between appeals to specific emotions (fear, anger, enthusiasm, and pride) and the engagement that such posts generate on Facebook. We created an engagement index sensitive to the Facebook page follower count and employed multilevel modelling techniques. We conducted a manual content analysis of posts by British political parties and their leaders (<em>N</em> = 1,203) during the Brexit referendum debate on Facebook. We found that engagement with a post substantially increases when appeals to anger, enthusiasm, and pride are present. Conversely, there is no relationship between appeals to fear and engagement. Thus, the results indicate with observational data what we know about the effects of emotions from experimental research in political psychology. Emotions of the same valence (e.g., fear and anger) have a different relationship with user engagement and, by extension, political behaviour and participation online. This indicates that to fully understand the role of emotions in generating user engagement on Facebook, we must go beyond the positive and negative dichotomy and look at discrete emotions. Lastly, British political actors used Facebook communication to generate online political participation during the Brexit debate.

Public health messages during a global emergency through an online community: a discourse and sentiment analysis

“…Findings are in keeping with literature linking the expression of anger with challenges to autonomy ( 20 ) and support a relationship between appeals for anger and engagement with online posts ( 22 ). Posts expressing anger, sometimes through the use of metaphors and idioms, often elicited empathetic responses in which people shared their problems or experiences to acknowledge confusion or concern.…”

“…A linguistic inquiry and word count study investigating open-ended diary responses found that anger expressions were more related to daily experienced anger than expressions of anxiety, sadness, depression, and positive emotion and their corresponding daily affect ( 21 ). In some cases, anger has been described as a strong driver of political participation and appeals to anger have been found to strongly predict engagement with Facebook posts ( 22 ).…”

Facebook reactions in the context of politics and social issues: a systematic literature review

“… Bil-Jaruzelska and Monzer (2022) examined the relationship between emotions and user engagement with political Facebook posts during the Brexit referendum, and found that engagement with a post substantially increased when appealing to anger, enthusiasm, and pride. A relationship between appeals to specific emotions (i.e., fear, anger, enthusiasm, and pride) and the engagement of users was observed.…”

Evaluating the status of theories of emotion in political science and psychology

“…There is infrequent reliance on a defined taxonomy to guide the selection. This often leads to selecting some emotion words, each presumed to identify a different emotion, even when some of those chosen emotion words have long been shown to be effective markers for the same emotion (Just et al, 2007;Bil-Jaruzelska and Monzer, 2022).…”
