Google AI overviews now reach over 2B users worldwide. But how reliable are they on high stakes topics - for instance, pregnancy and baby care?
We have a new paper - led by Desheng Hu, now accepted at @icwsm.bsky.social - exploring that and finding many issues

Can public involvement in AI evaluation improve the science? Or does it compromise quality, speed, cost?
In @pnas.org, Megan Price & I summarize challenges of AI evaluation, review strengths/weaknesses, & suggest how participatory methods can improve the science of AI

This @acm-cscw.bsky.social paper confirms the findings of the recent Nature paper on chrono feeds. Algorithmic feeds lead to more centrist, trustworthy content, but have little impact on user behavior. An independent audit of platforms w/o access to internal data!

Last week at CSCW, Catherine Han presented our work on journalists' unmet needs for protecting against harassment online. While the work targeted Twitter/X, it surfaces several nuances in users' needs that span future platforms as well (e.g., not wanting to filter out threats or visibly block users)
