The political effects of X's feed algorithm https://doi.org/10.1038/s41586-026-10098-2 Received: 16 December 2024 Accepted: 4 January 2026 Published online: 18 February 2026 Open access • Check for updates Germain Gauthier,5, Roland Hodler?5, Philine Widmer35 & Ekaterina Zhuravskaya3,4,5 m Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects. Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.
A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.
Moving from chronological feed to the algorithmic feed also increases engagement.
This is one of the most concerning papers I’ve read in awhile.
Have a look at my Blog Post regarding my experience at the 15th EOU Congress!
Had a blast presenting my work at two conferences!
Over the past month, I presented my 2nd PhD chapter on Mediterranean Gull migration at the 15th European Ornithologists' Congress (Wales) and the 22nd Italian Ornithological Conference (Puglia). Grateful to my 18 collaborators who made it possible!
Once again, many thanks to the BOU for awarding me the Conference Attendance Grant!
Thanks a lot for the support!!
Amazing! Can I be added as well, please? Thank you!
I got awarded two grants!
🟢 British Ecological Society – Training & Travel Grant
🟢 British Ornithologists’ Union – Member Conference Attendance Grant
These grants will support my oral presentation at the 15th European Ornithologists’ Union Congress in Bangor.

My second PhD chapter has been accepted for an oral presentation at the 15th EOU Congress in Bangor, Wales! I’ll be presenting my research on the Mediterranean Gull. Excited to discuss about this rather chaotic species! #EOU2025 #Ornithology #BirdMigration #MediterraneanGull #PhD #BirdResearch
Honoured to be invited to present my Master’s thesis remotely at the UNEP-WCMC Cambridge offices. In collaboration with BirdLife International and CEFE, my study focused on land-based threats to Atlantic seabirds, highlighting key conservation priorities.

Even though I will join remotely, the event will NOT be broadcast online. Many thanks to @themcmoraitshow.bsky.social for coordinating this!
🌈 Honored to Be a Panelist for Purple Friday!
I am honored to have been invited as a panelist by Queer Leiden University for this year's Purple Friday event at Leiden University. I’m excited to join a lineup of speakers and discuss how we can advocate for LGBTQIA+ equity within academia! ⬇️
