X's recommender system inadvertently profiles user political ideology

By PulseAugur Editorial · [1 sources] ·

A new research paper published on arXiv details how X's "Who to Follow" recommendation system inadvertently profiles users' ideological positions. Researchers analyzed recommendations shown to volunteers in France and reconstructed an approximation of the embedding used by X's recommender. They found that one direction within this embedding strongly correlates with a user's Left-Right political stance, distinct from other factors like age or popularity. The study suggests that this emergent political representation is not clearly addressed by current data protection definitions of profiling. AI

IMPACT Highlights potential privacy concerns and the need for updated regulations regarding AI's emergent profiling capabilities.

    Recommender system in X inadvertently profiles ideological positions of users

    arXiv:2602.02624v2 Announce Type: replace-cross Abstract: Several data protection laws restrict processing that reveals political opinions, irrespective of the controller's intent. Whether recommender systems do so as a by-product of optimizing relevance has not been measured. Fr…
