One of the issues that has come up again and again in my reporting on misinformation and social media is the massive influence social media companies have on research in the field.

Last night a preprint dropped that tries to get at this with some numbers. My piece in @science.org (and 🧪🧵 coming):
Nearly a third of social media research has undisclosed ties to industry, preprint claims
Industry-linked studies were also more likely to focus on particular topics, suggesting these ties may be skewing the field

Web tracking data has great potential for social science research 🚀 It also comes with its own challenges though! In this hands-on #GESISworkshop, you'll learn everything you need to know about preprocessing, handling, and analysing web tracking data.

I've added R support to my fork of llm-tldr github.com/sims1253/llm... very neat tool to help your agents make sense of large projects #rstats
GitHub - sims1253/llm-tldr at dev
95% token savings. 155x faster queries. 16 languages. LLMs can't read your entire codebase. TLDR extracts structure, traces dependencies, and gives them exactly what they need. - GitHub - sims...

My updated syllabus for Quantitative Text Analysis is available online. As I previous years, I made quite a few changes and added recent literature. Part 1 (still) covers classic text-as-data approaches; Part 2 focuses on transformers and LLMs.

This is a belated post about our paper in @poqjournal.bsky.social.

We analyzed 100 survey experiments fielded by TESS (tessexperiments.org), using only information from the proposals to identify intended hypotheses.

Here are some of the things we learned:
An Audit of Social Science Survey Experiments
Abstract. Survey experiments have become a popular methodology for causal inference across the social sciences. We study the efficacy of survey experiment

Want to get the data out of a PDF figure? As in, the actual data – not a rough trace-along-the-lines version?

We've got ISSUES. Literally.

We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do?
