We just published a meta-analysis, where one finding is that "number of sickdays" is a bounded, not seldom zero/one-inflated variable, which is unsuitable for meta-analysis based on mean/SD. Today, I came across a meta-analysis including sickday stats like mean=9 and SD=27. doi.org/10.1186/s40359-026-05648-2

I saw this meta-analysis shared a couple of times recently, so we took a look and re-analyzed the data. We found that the conclusion is almost entirely driven by publication bias. Both state-of-the-art and standard methods reduce the degree of the effect 2-3 fold. Moreover, the data no longer show statistical evidence for the main conclusions. Importantly, our findings do not imply that there is no positive effect of ChatGPT, or other large language models on learning; in fact, our analysis reveals that there is “absence of evidence” rather than “evidence of absence”. The present literature appears to be contaminated by publication bias; high-quality registered reports are needed to properly evaluate the effect of large language models in educational settings.

Meta Has Entered Its Death Spiral
Meta was hot during its early glory days, but it's starting to look as though it's entered a long, inexorable death spiral.
interesting to see them citing the meta-crisis and failure to address it as a prime reason for moving on - "our wisdom must grow in equal measure to our capacity to affect the world, lest we face the consequences" raising meta-crisis awareness among AI researchers is a great way to reduce x-risk 👍 >

I missed a lot of #metascience discourse in hospital, and am mostly sad I didn't get a chance to wade in on the absurdity of this being a paper in Nature in 2026; ignoring a decade of commentary from statisticians on OSC 2015 paper. nature.com/articles/s41586-025-10078-y

She identified a few and we contacted the authors to request their effect sizes and other variables for the studies in their papers.
