I am teaching a PhD seminar this fall which attempts to put a decision-theoretic lens (or lenses) on research design. So e.g., statistical decision theory, eliciting beliefs & preferences, and rational benchmarks. Here's a draft syllabus docs.google.com/document/d/1... What's missing?

What are your favorite connections between decision theory and experimental design? (both broadly considered) I'll share some of the connections I've made later.

Just out in WWW last week! 📜Our work on substitution patterns between Wikipedia and ChatGPT. We find *heterogeneous* impacts, where Wiki articles that are similar to ChatGPT outputs see a greater drop in views than dissimilar articles: arxiv.org/abs/2503.00757

This app is so cool! ShadeMap generates shadow maps by calculating the sun's position for a given location and time of year. It then traces a path from each map pixel toward the sun; if this path intersects an object like a building, mountain, or tree, the pixel is marked as shaded.

neat - wonder if there's some way to disentangle how these starter packs have shaped the resulting follower-following graph, compared to if we only had organic search

1st post on bsky - about bsky! I was fascinated with academic starter packs and made an interactive network to see academic communities and how they connect - a map of knowledge! link to an interactive & searchable network: ketikagarg.github.io/blueSkyAcade...

Coolest thing I've seen in a minute: hijacking mosquitoes to spread the malaria *vaccine* when they bite people www.nature.com/articles/d41...

This malaria vaccine is delivered by a mosquito bite

Bites from insects infected with modified malaria parasites boosted immunity and stopped people from contracting the disease.

Excited for the dialogue and the research community that this site is going to create!
