This is unbelievable. Thank you for highlighting it! I wanted to wonder if this list is not unilateral and confirmed by the included researchers, but if people even publish thereโ€ฆ

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.

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.

1/ Refreshing perspective from @oii.ox.ac.uk scholars: "Meticulous citation is a marker of well-researched, serious scholarship." Dr. Roxana Radu and @rocher.lc outline the harms of citation by LLMs: the 'provenance' of generated texts cannot be determined or cited.

Moving on from "Post-Soviet" States by John Daniszewski

The Associated Press decided in June 2023 to stop referring to the 14 countries that emerged independent of Russian occupation in 1991 countries as โ€œformer Soviet republics.โ€ The decision was taken on the advice of our journalists working in the region, and it has been generally well-received.

Inequality matters for ethnic conflict. But do group elites actually frame a situation as unjust? In a recent article (doi.org/10.1177/00323217251401758), @frederikgremler.bsky.social, Lea Haiges, Christina Zuber and I analyse โ€œgrievance framesโ€ in social media posts of ethnic organisations.

โ–ถ๏ธ Russian speakers are less willing to fight for Latvia than ethnic Latvians.

โ–ถ๏ธThis is driven by greater Soviet nostalgia. Russian speakers in Latvia are less likely to see Russia as responsible for the war against Ukraine, which reduces their willingness to fight.

Article abstract reads:

Nature protected areas are hailed as an institutional solution to the global biodi-versity crisis. However, conservation entails local economic costs for some com-munities and benefits for others. We propose that the establishment of protectedareas in Africa follows an ethno-political logic which implies that governmentsdistribute protected areas such that their ethnic constituencies are shielded fromtheir costs but enjoy their benefits. We test this argument using continent-widedata on ethnic groupsโ€™ power status and protected area establishment since inde-pendence. Difference-in-differences models show that political inclusion decreasesnature protection in groupsโ€™ settlement areas. However, this effect is reversed forprotected areas that plausibly generate tourism income. We also find that ethno-political inclusion is linked to legal degradation of protected areas. Our find-ings support long-voiced concerns by activists that politically marginalized groupscarry disproportional costs of conservation. This has implications, given the likelyexpansion of protected areas the decades to come.
