“Trending Now: The Legitimacy of the Police” A Factorial Vignette Study on the Effects of Procedural Justice and Social Media Interfacing

Recently, videos of negative police interactions have gone viral on social media causing riots and protests nationwide. However, police scholars have spent little time exploring how these videos affect the legitimacy of this authority or why these videos are interfaced with—e.g., shared, liked, direct messaged, and quoted—on social media. The purpose of this study is to examine the extent to which the content of police videos and the source of who is sharing them impacts the legitimacy of the police as well as the likelihood of social media interfacing. This study used a factorial vignette design with an online sample (N = 179) that presented one of six experimental vignettes describing a scenario in which the participant received a video of a police interaction via social media. Within each vignette, the officer behaved in a procedurally just or unjust way and the video was shared by either a local news source, best friend, or online friend. Participants were asked questions assessing the legitimacy of the officer, as well as the likelihood they would share, like, direct message, or quote the video on social media. Participants in the procedurally unjust condition perceived the officer as less legitimate and were more likely to share the video than those in the procedurally just condition. The manipulation of source had no significant effects. The results from this study indicate that police departments need to be sensitive to these videos that are being interfaced with on social media by striving for a strong and positive social media presence in order to aid in being deemed as a legitimate authority that represents the community.
