Why cybersecurity and information integrity are two sides of the same coin
With cybercriminals increasingly employing both cybersecurity and information-integrity-related threats, both disciplines are now integrally linked.

So many interesting findings in this work from @mmosleh.bsky.social and @dgrand.bsky.social comparing news sharing and engagement by quality and partisanship across 7 platforms

Notable partisan asymmetries. Low quality news gets more engagement, driven by traditional news getting poor engagement

🚨 New preprint alert:

We show that web-browsing GPT and LLaMA models can infer social media user demographics with reasonable accuracy—using only usernames.

This opens new possibilities for social media research in the post-API era but raises important privacy concerns.

The right often accuses fact-checkers of political bias
But we analyzed Community Notes on Musk's X and found posts flagged as "misleading" are 2.3x more likely to be written by Reps than Dems!
The issue is Reps sharing misinformation, not fact-checker bias...

Corrections of misinfo are often ignored. What can drive engagement?

-Social ties matter: users more likely to engage w corrections from accounts who followed user

"We're going to get rid of fact-checkers and replace them with community notes, similar to X, starting in the U.S," Mark Zuckerberg announces

He asserts that "the fact-checkers have just been too politically biased, and have destroyed more trust than they've created, especially in the U.S."
