One of the most-viewed PNAS articles in the last week is “Value misalignment in X’s feed algorithm is a reflection of value tensions in engagement.” Explore the article here: ow.ly/V1Mg50ZFWnP For more trending articles, visit ow.ly/XjLl50ZFWnO.

📰 Our piece with @ziv-e.bsky.social and @mbernst.bsky.social in The Conversation today. Feed algorithms optimize for engagement behavior because it is easy to measure. The result is that the values amplified in people's feeds are misaligned with what they value. theconversation.com/why-social-m...

“This highlights a core tension..of social media: frictions between users’ stated preferences and their behaviors..are exploited by engagement-maximizing algorithms to create runaway feedback loops of increasing value misalignment” Thanks @404ink.bsky.social @mjgault.bsky.social for the discussion!

Do our social media algorithms correctly reflect our values? Our new article published today in @pnas.org shows that the answer is often not, and that the content that gets promoted into their ranked feeds is often actively counter to our values.

Pleased to share our new paper forthcoming in @icwsm.bsky.social! We introduce a novel framework to measure value expressions in social media posts at scale, leveraging personalization to handle the inherent subjectivity of human values. arxiv.org/abs/2511.08453
