Estimating the effect size of moral contagion in online networks: A pre-registered replication and meta-analysis.
Article in PNAS nexus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Over 5 billion people now use social media platforms. As our social lives become increasingly entangled with online social networks, it is important to understand the dynamics of online information diffusion. This is particularly true for the political domain, as political elites, disinformation profiteers, and social activists all use social media to gain influence by spreading information. Recent work found that emotional expressions related to morality (moral-emotion expression) are associated with increased diffusion of political messages-a phenomenon we called "moral contagion." Here, we perform a large, pre-registered direct replication (
