ONLINE tomorrow: @guygrossman.bsky.social will present our new paper on the effects aid cuts for refugees. We follow 5400 households over 2 years and leverage a regression discontinuity design in Uganda. We find that self-reliance policies are not enough to mitigate the negative impact of cuts.

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.

Are female economists treated differently than males in academic seminars?

These authors wanted to know whether gender shapes how scholars are treated when presenting research.

So they built a massive dataset of 2,000+ economics seminars, job talks, and conference presentations from 2019–2023...

The old view of skilled emigration as a 'brain drain' has collapsed after a generation of research.

Skilled migrants cause innovation, technology transfer, and human capital investment in the countries they leave. The best summary is @mushfiq-econ.bsky.social et al.—>

I sometimes teach in Providence. In the classroom where I most frequently teach, there's a section labeled for where students are supposed to go for active shooters. It is a cliche of a phrase, but I want to echo the Professor here and say: it does not have to be this way.

All of us—including myself—should publish fewer but better papers.
And we should spend more of our time on scrutinizing existing work, so we know which claims can be trusted. But that's hard work with little recognition.
Thanks @sophieehill.bsky.social for doing it. Impressive 🕵️‍♀️ work. Fun to read.

Immediately below, same dot at A, then becomes a curving, meandering line that winds through the page and ends at a point with rays and a question mark emanating from it. Text reads: "Nothing can do this for you - that robs you of experience and conflates answers with learning. Rather, it's all the decisions you make along the way, the mistakes, struggles, and surprises! These pathways you create - this is learning.

Most Literature Reviews Miss the Point. Don’t Let Yours Critically Engaging Past Work to Confidently Shape Your Own

Most literature reviews miss the point.

Not because they’re sloppy.

But because they treat the literature like a box to tick.

In my latest Respect the Marble Post, I carve out a 6-step process to writing a meaningful lit review:
