What an honor to give a talk in the historical Enrico Fermi Research Center, hosted by Vittorio Loreto and Sony CSL. Notice Enrico Fermi in the background, doom-scrolling on his phone.

One year later - my reflections on what's happened to US science since the National Science Foundation grant terminations last year. The problem of misinformation isn't going away, but our ability to study and understand it is under attack. 1/ 🧪 www.tennessean.com/story/opinio...

The World Economic Forum’s Global Risks Report placed disinformation among the top global risks again in 2026, alongside geoeconomic confrontation and societal polarization. Disinfo catalyzes or worsens all other risks on the list. www.weforum.org/stories/2026...

Tapping into his favorite "rigged election" frame, yesterday Trump repeated allegations of Iranian intereference in U.S. elections to justify US/Israeli strikes on Iran. The hypocrisy of those allegations is telling — and hints towards his own interference plans. I wrote this thread into a blog:

Rewriting other people's original reporting and clickbait-wrapping the "new" story is not new. But a scumbag operation called "The Daily News Today" is doing it at AI-juiced scale. Alexios Mantzarlis, one of journalism's expert observers of this stuff, explains here:

The AI videos supercharging Russia's online disinformation campaigns www.bbc.com/news/article...

Epstein who?

OFFS. When Iran tried to interefere in 2020, researchers caught them and called them out. Then the Benz-Weiss-Taibbi-Musk-Jordan-Trump axis labeled those researchers "censors" ... and set about defunding them and dismantling their organizations.

Important experiment showing that social media algorithms do have political effects. www.nature.com/articles/s41...

This story via @theconversation.com weaves together research done with @yang3kc.bsky.social @baottruong.bsky.social and several others: 🧪 Swarms of AI bots can sway people's beliefs – threatening democracy theconversation.com/swarms-of-ai...

Is it acceptable to use AI to impersonate a candidate during an election and make it appear as though they did or said something they did not, without disclosing that the video is AI-generated or satire? news.bloomberglaw.com/litigation/h...

An important argument: Internet platforms must be held accountable for their actions, and US attacks against EU transparency and accountability regulations, equating them to "censorship", are ironic given the Trump administration’s own vast record of censorship.

Research showed that political disinformation on social media had negligible effects, but I always wondered if such tiny effects, when targeting battleground states, could influence close elections. A new paper analyzing voter-suppression ads shows this was the case in 2016: doi.org/10.1073/pnas...
