Fair cop! I didn't flag however I added that comment mostly selfishly for my own search history because Ackman's previous tweet seemed to disappear off HN - presumably inflammatory? Anyways - I normally try to be a better HN citizen - I promise to try harder! On-topic: porn is a live A/B test because it is already out there. We can measure some of the current harms to children (adolescent or not) and adults. The B test is introducing new rules and then either: comparing harm between jurisdictive boundaries or: perhaps compare between before/after (hopefully preplan to collect data before new rules were introduced). Either way, Legislation rarely mixes with science so even trying to measure metrics is likely fruitless. And even then Goodhart turns up to tell you your metrics failed to achieve desired outcomes.
