The reason why he’s speaking is because Utah introduced groundbreaking legislation to hold social media companies accountable.

Folks the conference can’t just be an echo chamber we need to hear from people on the other side who have an interest in countering disinformation on social media. Change isn’t going to enact itself we need people from within driving that change. if they have ideas, we should hear them out.

And we need regulation to enforce safety-by-design feeds for kids for sure I think! We need strong enforcement of appropriate regulation but I'm just not sure if bans are the answer - there's very little evidence of their efficacy and they take away all autonomy maybe better used a temp lever.

Yes indeed both the research we have says they don’t have the desired effect but also we don’t have very much high quality research on it. I’d love to see more large scale population trials in schools.

(3) We can't hide from technology, but instead of restricting kids' autonomy, we need to make the companies pay by forcing safe feeds and building digital resilience.

Despite all the chatter, social media bans for teens lack evidence! New paper out in Nature Health.

(1) Harms from social media are real & serious.

(2) We need regulatory action but bans are not nuanced, do not empower youth, & are not supported by evidence.

This paper argues that the rush to study gen AI has led researchers to focus on the same topics and rely on the same methods. As a result, creativity is limited and the diversity of ideas needed to keep research flexible, strong, and innovative is being pushed aside.

New article in Nature describes a field experiment on X which shows that assigning users to an algorithmic feed pushes conservative content and demotes mainstream news.

Sounds obvious but important in light of prior claims algorithms don't cause attitudinal changes.

People form beliefs not only as individual agents, but as members of social groups.

Children (4-6 years old) who belonged to a group were more convinced by evidence that supported their ingroup’s belief (and were less convinced by evidence that opposed their ingroup): www.nature.com/articles/s41...

The Matrix of Coordinated Influence. Traditional frameworks for analyzing online influence focus on the distinction between human and automated actors (Identity Axis) or between spontaneous and coordinated behavior (Articulation Axis). Bot Nets (top-left) rely on synthetic identities and automated scripts. Troll Farms (bottom-left) use human operators to manage fake personas. Grassroots Action (bottom-right) involves verified citizens sharing self-authored views. Cyborg Propaganda (top-right) represents a new paradigm: verified human users disseminating centrally generated, algorithmically generated narratives, effectively β€˜hybridizing’ the authenticity of the grassroots with the scale of the botnet.

The distinction between grassroots activism and automated influence is collapsing.

We typically worry about "bot farms" or "troll factories." But a distinct, more complex threat is emerging. We call it "Cyborg Propaganda."

He struck me as an extreme sceptic and cynic so that description doesn’t really resonate with me but I didn’t know him very well so I guess he could be but his mind didn’t really strike me as the gullible kind.

There have been increasingly shrill accusations against the EU over its digital legislation, based on accusations of "censorship" by defenders of "free speech" -- including, so it appears, the right to peddle an AI app that seemingly produces child sexual abuse material (CSAM).

It's disturbing to see many of the the major figures in moral cognition all over the Epstein files

He was friendly with a huge number of the leading figures in the field, including giving millions to their labs, long after he pled guilty to sexually abusing young girls
