How do anti-misinformation policies work? RCT & structural estimation on Twitter/𝕏 in the US: priming outperforms fact-checking by raising salience of reputation at low cost, curbing false news & preserving true news. Veracity updating matters less.

Local projections are surprisingly robust to misspecification. By contrast, VAR confidence intervals with short-to-moderate lag length can severely undercover for misspecification that is small, difficult to detect, and cannot be ruled out a priori.
