I'm briefly quoted in this long but important investigative piece about Storm-1516, the most potent weapon in Russia’s disinformation war.

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?

Does health misinformation kill? Yes.
Our latest paper is finally out with evidence of a causal link between exposure to antivax content on Xitter and deaths.

Political disinfo on social media has overall negligible effects. I always wondered if such small effects, when targeting battleground states, could influence close elections. A new paper analyzing voter-suppression ads shows this was the case in 2016:

Latest working paper 🧪 w/ Shalmoli Ghosh and @mdeverna2 shows that AI porn and NSFW deepfakes targeting women are being commoditized

🚨 New working paper 🚨
What happens when you add money competition to generative AI creation?
On Civitai—a prominent platform for gen-AI content/tools w. millions of users—you get a growing marketplace for NSFW requests and a nontrivial stream of deepfakes.

Our latest paper in @ScienceMagazine warns about malicious AI swarms, agents capable of adaptive influence campaigns at scale. We already observed some in the wild (picture). AI is a real threat to democracy.

AI now allows propaganda campaigns to reach unprecedented scale and precision.
Our new paper in @sciencemagazine Magazine explains how a disruptive threat is emerging: swarms of collaborative, malicious AI agents.
We describe the potential risks and some interventions for this growing threat to organizations, institutions, and nations.
This paper was led by @daniel_thilo & @JonasKunst22246 :
