Make your voice heard! #ic2s2

The final day’s lightning round offered another eight sharp takes on media bias, science of science, etc. Which talk stood out to you? #ic2s2

Please vote for the best poster #ic2s2

Prediction and explanation, together. Duncan Watts opened our final day with a keynote on “Integrating explanation and prediction in computational social science,” showing how pairing causal insight with predictive testing can push computational social science forward. #ic2s2

Want to keep the conversations flowing at #ic2s2? A crowd is heading to a focal bar: Arbis Kafé & Salonger (outside), a short walk from the conference venue. maps.app.goo.gl/ekmuCNQeWy4e...

Arnout van de Rijt gave Day 2 a strong ending with his keynote, “Luck and success in millions of life courses.” Do early strokes of luck widen life-course income gaps? This keynote offered fresh causal evidence on chance and inequality. #ic2s2

Day 2 Keynotes. How can computational methods sharpen our grasp of culture? In Amir Goldberg’s inspiring keynote, he showed how computational methods reveal hidden cultural patterns. #ic2s2

Afternoon parallel sessions are in progress—join the discussions!

More than 100 posters are on display in the Atrium. Explore your favorite topics, chat with the authors, and cast your vote. #ic2s2

Day 2 and the momentum at #ic2s2 ’25 keeps building. Parallel sessions are running across multiple tracks: network science, social media, economics, science of science, and more.

Eight lightning talks just delivered rapid-fire insights on human–LLM interactions, mobility, and inequality. Which one impressed you most? Share your thoughts! #ic2s2

Day 2 Keynotes kicked off with Laura Nelson's inspiring presentation, “Why Qualitative Research Needs Computational Social Science”. What is the state of this maturing field called qualitative computational methods? What are the ongoing debates and futures? #ic2s2

Hope your first day of #ic2s2 ‘25 was fruitful. Reminder: afternoon keynotes begin at 4:30 pm sharp, please arrive promptly so you don’t miss a moment. See you tomorrow!
