Seconding Galder in bringing this important research finding to wider attention (CCing the Wiki-research list as well).
If I may, we also just covered this in the new Signpost with some additional context and detail that some here might find interesting: "Wikimedia Foundation reports 8% traffic drop since last year due to 'the impact of generative AI and social media'" <https://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2025-10-20/In_the_media#Wikimedia_Foundation_reports_8%25_traffic_drop_since_last_year_due_to_%22the_impact_of_generative_AI_and_social_media%22> .[1] As mentioned there, the problem of quantifying the impact of generative AI on Wikipedia readership has already attracted considerable attention by academic researchers in the almost three years since ChatGPT launched. I even think it's safe to say that many might regard it as one of the most important research questions about Wikipedia and AI currently.[2] However, the academic research publications about this - admittedly difficult - topic have been a bit of a mixed bag so far <https://meta.wikimedia.org/wiki/Research:Newsletter/2025/March#So_again,_what_has_the_impact_of_ChatGPT_really_been?>. (Even what I would regard as the best paper among these, which Mako and I also chose to highlight in our annual "State of Wikimedia Research 2024-2025" talk at Wikimania this year, still has some potential statistical shortcomings <https://en.wikipedia.org/wiki/Wikipedia_talk:Wikipedia_Signpost/2025-03-22/Recent_research#%22Wikipedia_Contributions_in_the_Wake_of_ChatGPT%22>. And I am not aware of much peer-reviewed insight that goes beyond the early-years ChatGPT.) So it's great to see that the Wikimedia Foundation has now itself jumped into this breach. It is evidently well positioned to do so. Not just because it has potentially useful internal data that was not available to the aforementioned external researchers (say referrer information <https://wikitech.wikimedia.org/wiki/Data_Platform/Data_Lake/Traffic/Pageview_hourly>, or now also the data derived from the unique reader cookies WMF introduced earlier this year, which enable better but still relatively privacy-friendly tracking of Wikipedia readers). But also e.g. because of the foundational work <https://research.wikimedia.org/foundational.html> its own researchers already did some years ago on "Detecting and Gauging Impact on Wikipedia Page Views" (IMO a paper worth looking at for anyone investigating such questions). Unfortunately though, Marshall Miller's Diff post doesn't contain any concrete information about the methodology used to causally attribute the drop to those two factors, nor any links to further details. Can we expect the underlying statistical analysis to be published soon? It would also be interesting to know e.g. each factor's share in this 8% drop (is it say 7% from AI vs. 1% from social media, or vice versa?) Or, to circle back a little towards Galder's points, whether different Wikipedia languages were affected differently, etc. Regards, Tilman [1[ Alongside a somewhat related story <https://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2025-10-20/In_the_media#Elon_Musk_announces_AI-based_%22Grokipedia%22_to_challenge_Wikipedia> about a certain well-known US entrepreneur trying to replace Wikipedia with a new AI-based encyclopedia, also mentioning some similar but less well-known efforts. [2] For some reason though, this central research question didn't make it into the list <https://meta.wikimedia.org/wiki/Artificial_intelligence/Bellagio_2024> of research directions about the implications of AI for the knowledge commons that was drafted at the February 2024 Bellagio symposium convened by the Wikimedia Foundation. But as we heard recently on this mailing list <https://lists.wikimedia.org/hyperkitty/list/[email protected]/thread/YI5KUYTCCYTTEISGM3APGXYMQUVFAZNM/#5CPAYECG7XQ5NXVUJ3VODJGLWBFV2NBS>, the WMF research department is still working on getting a fuller documentation of that event's outcomes ready for publication. (At that point we will hopefully also see an attempt to solicit wider input on this draft agenda, from other researchers and the editor community, the latter appearing particularly relevant as the project's stated purpose is to convey "vital questions volunteer contributors have raised"). And in any case, it or some of its colleagues have evidently now tackled this research question themselves.
