 A comment on "Overperception of moral outrage in online social networks inflates beliefs about intergroup hostility"Kevin R. Carriere No 309, I4R Discussion Paper Series from The Institute for Replication (I4R) Abstract: Brady et al. (2023) investigated whether people overperceive moral outrage in social media and whether exposure to outrage-saturated newsfeeds amplifies perceived collective outrage and intergroup hostility across five studies. Participants who viewed the high-overperception feed judged the collective outrage of their social network as substantially large. They also found that exposure to highly overperceived feeds increased perceived social appropriateness, increased affective polarization, and heightened perceived ideological extremity. In this commentary, I successfully computationally reproduce all reported effects even after correcting a data-processing error that unintentionally duplicated observations in Studies 1-3, including the large between-condition difference in perceived collective outrage (Study 4). Bootstrapping 2,000 resamples confirmed that the 95% bias-corrected and accelerated CI [2.09, 2.51] matches the analytic interval, indicating an exceptionally stable effect. I also replicate Study 5 using tweet-level mixed-effects models that preserve the nested structure of the data. These reanalyses reproduce the main effects of overperceived feeds on social appropriateness (b = 0.67, p Date: 2026 Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:zbw:i4rdps:309 Access Statistics for this paper More papers in I4R Discussion Paper Series from The Institute for Replication (I4R) |
