I most say this has been an absurd process. Even half of the authors withdrew their names. Yet it becomes a comment vs bs answer as usual. It’s impossible to set the record straight.

Are preferences for authoritarian rule individual predispositions—or can they spread socially? Using field + survey experiments in the Norwegian Armed Forces, we show that openness to strongman rule can spread socially. American Journal of Political Science: onlinelibrary.wiley.com/doi/10.1111/...

The increasing popularity of strongman rule in democratic societies underscores the need to explore how authoritarian regime preferences might spread socially. We assess the role of social influence ...

It is not just that 'ideally' criteria for publication should be the same for significant and non-significant results - it is literally in the code of conduct for research integrity. If you do not act in line with this, you are violating the code of conduct for research integrity.

Good morning. A coda (from me) on this replication business. While I understand the impulse, it is disheartening that most of the discussion generated by this replication is about the replication "process" -- both the APSR's process and my own process. What could we be talking about instead?

The answer to this excellent question from @kotsadam + Løvgren: yes! List experiments do not, in general, seem to be an effective tool for measuring IPV; we should not use them unless there is a convincing reason to think otherwise

🧵 When authoritarian leaders attack judges as "enemies," history shows us exactly where this leads. Trump's assault on "USA HATING JUDGES" isn't just inflammatory rhetoric—it's following a script written by strongmen worldwide. But other countries show us how to fight back.

The JHR @j-humanresources.bsky.social · 28/03/2025
A study by Nicolai T. Borgen, Lars J. Kirkebøen, @kotsadam.bsky.social, and @oraaum.bsky.social found that funding 600 extra teachers cut the student-teacher ratio by 10%, boosted student well-being and the school environment, but did not improve academics. doi.org/10.3368/jhr....
Do Funds for More Teachers Improve Student Outcomes?
Nicolai T. Borgen, Lars J. Kirkebøen, Andreas Kotsadam and Oddbjørn Raaum
We investigate the effects of a large-scale Norwegian intervention that provided extra teachers to 166 lower secondary schools with relatively high student-teacher ratios and low average grades. We exploit these two margins using a regression discontinuity setup and find that the intervention reduced the student-teacher ratio by around 10%, without crowding out other school resources. The extra funding did not improve test scores and medium-term academic outcomes, and we can reject even small positive effects. We do find that more teachers improved the school environment, including self-reported student well-being, but with the largest impact on aspects of the school environment most weakly associated with better academic outcomes.
