What unifies, and what distinguishes, social media designs? Are all the Twitter spinoffs actually meaningfully different designs from each other? Form-From is a design space from Amy Zhang, myself, David Karger (hci.social/@karger), and Mark Ackerman that will appear at #cscw2024 arxiv.org/abs/2402.05388

The old adage, "common sense is not so common," still holds true, according to new research from Prof. Duncan Watts & Mark Whiting that found a significant variation in what individuals consider common sense: whr.tn/3utMPjk 📝: @WhartonKnows

This paper is so interesting! "Common sense, while often portrayed as universal, is paradoxically also often claimed not to exist." pnas.org/doi/10.1073/pn…

Our new paper explains why some life outcomes are hard to predict. We combined machine learning, a mathematical decomposition, and in-depth qualitative interviews to understand the origins of unpredictability: pnas.org/doi/10.1073/pn…

How should we think about measuring common sense — a product of social construction — in LLMs, beyond the accuracy scores reported in popular static benchmarks? My work with Mark Whiting and Duncan Watts at CSSLab at Penn will be presented in today's poster session at IC2S2, 1:30pm.

One person I feel who is insufficiently appreciated is Hadley Wickham. The results of his work are everywhere, every journal and conference I know. He changed the history of science.

Prior work shows that LLMs can make serious errors when predicting human behavior. How can we draw valid, precise, and cost-effective inferences from LLMs on causal effects (and other parameters)? 🚨We propose the Mixed Subjects Design in a new working paper.🧵👇

Gino's case against us has been dismissed. Scientists cannot effectively sue other scientists for exposing fraud/errors in their work. Those who work to correct the scientific record can sleep better tonight. Those who don’t want it corrected, well, I don’t care how they sleep.

Q: This will never work. A: It already works. We've been using it for years, for everything. Q: But I can't imagine how it would work. A: If you could imagine it, we wouldn't have had to build it.

Duncan Watts First q from Anna Harvey: When testing policies with partner orgs, they can't possibly run a huge number of studies, and partner orgs might not be representative of the field? Duncan Watts: You can adapt to field methods, as long as your data can be modeled, and....

The common sense project is now live! @DuncanJWatts, Mark Whiting, Amirhossein Nakhaei and Josh Nguyen from the CSSLab invite you to take a quick survey 📝 and measure your common sense💡 commonsense.seas.upenn.edu You can read more about the project here: css.seas.upenn.edu/commonsensical…

Everybody trivializes common sense because we believe it is self-evident and universal. But is it really? Find out by participating in our Common Sense Project: commonsense.seas.upenn.edu. With @AmirhosNakh, Mark Whiting, and @DuncanJWatts at @CSSPenn. 1/n

Marcus Edvalson Bro, I can make 1 liter of Anthrax in an afternoon, Grok just wrote me a 20 page detailed report and instructions on how to do it. It also listed all websites where I can buy the materials and chemicals I need as a private person living in Europe. It also made a detailed list
