We have started the second day of the MPWZ-CEPR Text-as-Data Workshop (already the 11th edition). Join us here: ethz.zoom.us/j/62143211732 Text-as-data is used across economics now -- from projects on gender norms to mafia networks, and sanctions evasion, to superstar scientists and AI patents 📈📊

📕 💻 📈 Are you curious about the latest work on text-as-data in economics and beyond? We have just kicked off the 11th MPWZ-CEPR Text-as-Data Workshop! We will "time-travel" with LLMs, track narratives, and much more! 40 papers, one link: ethz.zoom.us/j/62143211732. Program: tinyurl.com/yc2zvy7u

Can feed algorithms shape what people think about politics? Our paper "The Political Effects of X's Feed Algorithm" is out today in Nature and answers "Yes." www.nature.com/articles/s41...

We ran this experiment independently: no platform cooperation, no corporate funding. Instead, it was funded by the Swiss National Science Foundation SNSF.

This is a behavioral lock-in: once you follow new accounts promoted by the algorithm, they stay in your feed regardless of which feed setting you use.

But here's the twist: switching the algorithm OFF did not reverse the effects. Users who went from algorithmic to chronological feeds showed no significant change in political attitudes. The effects of algorithm exposure are sticky.

We recruited ~5,000 active X users in the US and randomly assigned them to use either the algorithmic feed ("For You") or the chronological feed ("Following") for seven weeks in summer 2023. We measured their political attitudes before and after with surveys.
