Why don't reported treatment effects generalize? On Thursday, Ying Jin explained that it is not only because of covariate shift (the "usual suspect") — but also because of conditional shift. Quantifying their relative contributions is important in all experimental research.

On Wednesday, SICSS participants learned how to conduct survey experiments and text analysis in climate politics research from @sabrinabarias.bsky.social of Lehigh University.

As LLMs become increasingly pervasive in social science research, questions about replication, reproducibility, ground truth and wisdom of the crowd are more important than ever. Thank you to Arthur Spirling and Adam Bouyamourn of @princetonpolitics.bsky.social for sharing your latest research today

The first day of SICSS-Penn 2026 just recently concluded! We were honored to have @dhopkins1776.bsky.social deliver the opening remarks, and @dalbarra.bsky.social give the first lecture on AI and the psychology of persuasion.

We are pleased to extend our congratulations to 40 scholars who have been accepted to SICSS-Penn in 2026! Please check your email if you submitted an application. We look forward to welcoming you to Philadelphia this summer.

Two more days to apply for the Summer Institute in Computational Social Science at Penn! We look forward to welcoming you to Philadelphia. sicss.io/2026/penn/ap...

Language technologies like LLMs encode an enormous amount of cultural knowledge. Today, we learn from @lyleungar.bsky.social of @pennengineering.bsky.social about how to use them to study social norms around the world.

Welcome to the eighth day of SICSS-Penn 2025! We are honored to have @janeesberg.bsky.social of @upenn.edu's Political Science Department, who talked about her work on using text analysis to understand political censorship.

Facilitating cross-partisan conversations is a potential intervention to address affective polarization — but the topic of discussion matters! Today, we welcome James Houghton of @csspenn.bsky.social to talk about his "deliberation lab" in this direction.

How do different people — and AI models — perceive hate speech? What are the implications of this heterogeneity in content moderation on social media? We're excited learn from @thomasdavidson.bsky.social of Rutgers University at SICSS-Penn today!

@yamilrvelez.bsky.social from @columbiauniversity.bsky.social opened the second week of SICSS-Penn 2025 with his talk, "Generative AI and Respondent-Centered Social Science."

On day 4, @danisbassett.bsky.social‬ from @pennengineering.bsky.social‬ used network science to investigate the different "styles" of human curiosity — Are we more like "busybodies," "hunters," or "dancers"? — and how they might help us build better, more human-like artificial intelligence.

What is the value of a career? What are the effects of automation on the labor market? We are excited to have Pinar Yildirim at the Wharton School who is talking about "Automation, Career Values, and Political Preferences."

What can we do to address the replication crisis, the file drawer problem, and incommensurable experiments? We are honored to welcome Sean Ellis this morning to talk about the amazing "megastudies" conducted at @bcfginitiative.bsky.social.

The first day of SICSS-Penn 2025 just concluded with @manoelhortaribeiro.bsky.social's talk "Content Curation in Online Platforms."

Welcome to SICSS-Penn 2025! We are excited to have our faculty organizers, @xisong.bsky.social and @dhopkins1776.bsky.social, deliver opening remarks this morning.

We are proud to welcome 35 scholars who bring a remarkable breadth of academic and technical expertise to SICSS-Penn 2025. Stay tuned to see what they will achieve this summer! #CompSocSci #SICSS #SICSS2025

SICSS-Penn application deadline is extended until March 21, 2025. Submit your application here: sicss.io/2025/penn/ap...

The application deadline for SICSS-Penn is extended for one week. Submit your application by March 14 to attend our amazing program!
