NIH is reworking social and behavioral study sections including *eliminating SSPA and SSPB*. There will be one new study section Population Dynamics and Health.

Bad news since SSP originally received so many applications, they needed 2 difft study sections to process them.

In “Cohort Prevalence Estimates Are Sensitive to Prebaseline Mortality,” Molly Rosenberg et al. show that “prebaseline mortality patterns can meaningfully impact health outcome measures in cohort studies” & so represent a potential source of bias. read.dukeupress.edu/demography/a...

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.

A screen shot of the National Couples' Health and Time Study webiste at DSDR, with the language "This repository is under review for potential modification in compliance with Administration directives." at the top circled in red.

I just noticed that NCHAT's @icpsr.bsky.social website has a new disclaimer "This repository is under review for potential modification in compliance with Administration directives." I am not sure what this means, but I wanted to let everyone know.

That's amazing, what a great outcome!

The Contribution of Drug Overdose to Educational Gradients in Life Expectancy in the United States, 1992–2011 - Demography Since the mid-1990s, the United States has witnessed a dramatic rise in drug overdose mortality. Educational gradients in life expectancy widened over the same period, and drug overdose likely plays a...

I've always thought Jessica Ho's piece on the contribution of opioid overdoses to the education gradient in life expectancy was a clever way of getting around imperfect mortality data by combining data from two different sources. link.springer.com/article/10.1...
