Briefing: X and Trump admin decide fact-checking is good, actually Plus: Check out our redesigned and updated Academic Library and a bunch of new OSINT tools

You will also notice that 21/49 notes explicitly refer to a fact-checker. This a reminder that you can't just starve the ecosystem of professional journalistic endeavors and hope that the crowd will do its job instead.

Here are 49 notes flagging that a tweet was posting AI content about the Iran war without disclosing.

As you will see, most did not reach "helpful" status and will therefore probably not be used to demonetize creators spreading disinfo.

The policy may have decent precision, but not good recall.

In today's free @indicator.media I do my best to set aside the hypocrisy of X launching a fact-checking policy and the State Department applauding it -- and assess the merits of the policy itself.

LLMs can unmask pseudonymous users at scale with surprising accuracy Pseudonymity has never been perfect for preserving privacy. Soon it may be pointless.

This feels a little oversold based on the recall in the underlying paper, but only a little.

Mass deanonymization is a legitimate concern especially because of the cost, speed and scale at which LLM agents can operate.

Analysis Suggests School Was Hit Amid U.S. Strikes on Iranian Naval Base

Official statements placing U.S. forces in the area – along w/ analysis of social posts, videos, sat. images – suggest U.S. forces bombed a school in Minab, Iran during strikes targeting an IRGC base. Over 150 were killed, Iranian officials say. www.nytimes.com/2026/03/05/w...

right. and there's also metadata, which as we've shown on Indicator does not reliably carry over

I also can't seem to find any more details about the policy on the policy pages... Typically these things would be associated to a blog post and a policy page update

I hope this puts to rest any absurd assumption that the politically-motivated carping about "fact-checking/Trust & Safety is censorship" was in good faith

yes, take this with a pinch of salt as I only pulled it very fast and haven't QA'ed but looks like notes being written has gone up, helpful notes is stable-ish to declining

not a bad hypothesis! but overall numbers are going down too so i'm thinking maybe it's a rating side question of fewer people agreeing on what even is helpful

Interesting:

Contrary to my prediction, the share of AI notes on X appears to be dipping down. The trend has been notable and substantial over the past week.

All I can think about is Jeff Bezos saying that he slashed jobs at the Washington Post β€” including those of foreign correspondents in the Middle East β€” based on "the data," and a few weeks later a whole war breaks out in the Middle East that these laid off folks would have covered as true experts.

Scientists Asked AI to Describe Neanderthals. It Served Up Misinformation. The results were grossly inaccurate, stemming from AI pulling its information from outdated stereotypes in lieu of paywalled research.

Not sure who needs to hear this but you can't use ChatGPT for realistic descriptions or images of Neanderthals.

(there's a serious takeaway: unequal access to an evolving knowledge basis can steer AI off course.)

GenAI is why Kant developed the Categorical Imperative.

Ask: What if everyone did this? Could the world still function? Would I accept that?

And here is the best example in living color 11,000 episiodes per day of AI slop.

I went to see Operation Mincemeat last night and it was glorious. Highly recommend.
