Fig. 4: Analysis of reposting mechanisms.
From: Community-based fact-checking reduces the spread of misleading posts on X (formerly Twitter)
The estimated ATTs (circles) across different groups of reposters. Here we distinguish between (i) reposters that had prior interactions with the authors of the fact-checked post, (ii) the verification status of reposters, (iii) the political orientation of reposters, and (iv) prior exposure of reposters to misinformation on X (formerly Twitter). The ATT estimations are based on a random subset of 50,608 repost time series observations for N = 3136 posts. Post-level random effects are included. Full estimation results are in Supplementary Note 9. In all plots, the error bars represent 99% CIs derived using the bootstrap method for 1000 resamples; the grey bands visualize the ATT (with 99% CIs) estimated via the two-period DiD model based on reposts from all categories of reposters.
