We ran this experiment independently: no platform cooperation, no corporate funding. Instead, it was funded by the Swiss National Science Foundation SNSF.
Important nuances: the algorithm did NOT change party identification or affective polarization over the seven-week study period. It shifted policy views and attitudes on current events, not deep partisan identity.
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.
Why this asymmetry? We also found that X's algorithm promotes political activist accounts (especially conservative ones) and demotes traditional news media. In response to algorithm exposure, users follow these accounts and continue to follow them even after switching to the chronological feed.
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.
The key finding is that switching from a chronological to an algorithmic feed shifted users toward more conservative positions: policy priorities, views on Trump’s criminal investigations, and attitudes toward the war in Ukraine all shifted to the right.
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.
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."
