Grok system prompts are now public. Transparency is helpful. ChatGPT and Gemini also have prompts. So, Grok is instructed to be “extremely skeptical” and not to “blindly defer to mainstream authority or media.” Grok now says “both sides of this debate have biases” about number of Holocaust deaths.

seeing some joke comments about the subject matter of this paper so it seems important to clarify that studying competition between platforms and the effect of regulations in a setting with potentials for truly massive externalities is just a very high value added activity for economists to do

Meta & Apple 🍏 were slapped with the first non-compliance-decisions in the (short) history of the Digital Markets Act #DMA. This regulation for taming Big Tech finally shows its teeth. Or does it? Here is our report in the SCiDA blog! scidaproject.com/2025/04/24/b...

Pornhub's removal of all non-verified content led to a 41% drop in traffic within 1 month. Much of the displaced traffic was absorbed by competing platforms, including less regulated fringe websites (+55% visits) and mainstream competitors (+10%). papers.ssrn.com/sol3/papers....

WHAT HAPPENS WHEN A DOMINANT PLATFORM SUDDENLY MODERATES A LARGE SHARE OF ITS CONTENT? 🚨 With Matt Mitchell, Martin Quinn & @mikybartoli.bsky.social, we study one of the largest moderation shocks ever: Pornhub’s 2020 purge of 10M+ non-verified videos (80% of content). 🧵👇

Looking forward to this talk!
