🚨(Software) Update: In my PhD, I had a side project to fix an annoying problem: when you ask 5 people to label the same thing, you often get different answers. But in ML (and lots of other analyses), you still need a single aggregated answer. Using the majority vote is easy–but often wrong. 1/N

I built this for fun. Not really sure what to do with it. Maybe it will be useful to people trying to understand polling. Might even be a decent teaching example. (Feedback welcome. I am not a web designer, please be kind.) poll-simulator.netlify.app

Very interesting new study using CES data from Scott Platte and @bfschaffner.bsky.social new in @psrm.bsky.social www.cambridge.org/core/journal...

As @seanjwestwood.bsky.social's terrifying new PNAS article demonstrates, LLMs can now pass almost every attention check, mirror personas, stay consistent across pages, and systematically bias responses in the aggregate. So here’s a different angle: verify physical presence, not text.

Many think LLM-simulated participants can transform behavioral science. But there's been a lack of accessible discussion of what it means to validate LLMs for behavioral scientists. Under what conditions can we trust LLMs to learn about human parameters? Our paper maps the validation landscape. 1/

Survey experiments' popularity in political science is getting attention. What is good and bad about them? How can one maximize their benefits and mitigate their downsides? Greg Huber and I wrote up our thoughts: Paywalled: doi.org/10.1016/bs.h... Free: m-graham.com/papers/Huber...

Lots of concern about ⬆️ of survey experiments as signal of “credible causal evidence”, but I’m genuinely curious: what’s the alternative if we study trends that happen rarely, are hard to measure, or lack data? Causality aside, seems like surveys and/or experiments are an incredibly useful tool?

How common are “survey professionals” - people who take dozens of online surveys for pay - across online panels, and do they harm data quality? Our paper, FirstView at @politicalanalysis.bsky.social, tackles this question using browsing data from three U.S. samples (Facebook, YouGov, and Lucid):

Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

We just released version 3.1 of WhoGov, a global dataset on members of government from 1966-2023. The update fixes the mistakes that came to our attention while creating the Paths to Power dataset + mistakes users have notified us of More additions and updates to WhoGov are on their way, including:

In poli sci, "the top 20% of departments produced 75% of all faculty and the bottom 50% accounted for less than 5% of all tenure track faculty members at a research university. 49 programs did not have a single graduate placed in a TT position at a PhD-granting department in the past 10 years."

🚨 Updated working paper! Ekin Dursun and I ask what instruments best manipulate emotions on surveys (osf.io/56h4g). We find that vignettes really work! They have large effects on emotions of interest & smaller effects on emotions *not* of interest. But as always, it's complicated.👇 (1/17)
