I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

It must be very hard to publish null results
Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.

It’s been so exciting to work on this registered report with Eli and Francesca. Happy to see it out in the JOP. And the registered report format has been absolutely amazing.

Thrilled that the first paper in my PhD thesis “State Action and Moral Attitudes toward Sexual Consent”, co-authored with Francesca R. Jensenius and @oskorge.bsky.social , has been accepted for publication in the @thejop.bsky.social! 1/

Min kollega @oskorge.bsky.social har skrevet om mannsidealer og venstresida. Bravo, sier jeg, vi må ha et mer inkluderende mannsideal som ikke bygger på nedarvet skam, men gode, praktiske evner til empati og tilstedeværelse. www.vg.no/nyheter/i/8q...

Meninger: Ja til venstresidemannen!

I min egen iver etter å anerkjenne kvinners likestillingsutfordringer, har jeg vært blind for den positive rollen vi menn kan spille i kraft av å være menn.

Anyone who thinks that when businesses complain about a competition regulator, siding with the businesses is to be growth-friendly, makes a huge mistake. Competition is good for growth AND disliked by businesses (who must work harder to do well). Wanting to make businesses happy will lower growth.

This paper by the late, great Nick Crafts, on competition and productivity in the UK, well worth a read: cepr.org/voxeu/column...

**New working paper** How does the under-representation of females in Economics affect the career trajectory of female Ph.D. students? Sahar Parsa and I look at this in a new working paper by exploring sabbatical leaves taken by female professors at top-50 US Econ departments.
