How do moral values difer in Tweets on social movements?

In this paper, we analyze and compare the representation of social movements on social media from the perspective of morality. Following previous research, which found associations between morality, collective action, and social decision-making, we postulate that moral values are distinct across diferent movements since these movements represent moral values of those who support or oppose them. The result of our analysis of four movements as represented on Twiter (#BlackLivesMater, #WhiteLivesMater, #AllLivesMater, and #BlueLivesMater) reveal that #BlueLivesMater represents values such as Care, Harm, Loyalty, and Authority, while #WhiteLivesMater features Harm and Fairness. Moreover, we find that Harm is the most prominent moral value in all of our datasets. Our analysis provides a robust understanding of authors' moral stances, which contextualizes the influence of movements on people, and how these movements are perceived in society.
