Not very surprising, but good to have an estimate: "shares without clicks’ (SwoCs) constitute around 75% of forwarded links."

Study: Susceptibility to online misinformation: pnas.org/doi/epub/10.1073/pn…
"...older age, higher analytical thinking skills, and identifying as a Democrat are associated with higher discrimination ability."
"...political identity can shape what people perceive to be true, which can in turn shape their behavior."
"...a strong association between familiarity with a news headline and the likelihood that participants would believe it to be true, regardless of whether it was or not. Familiarity can easily be gamed online..."

We just published #DSA40 Newsletter #2 🙌🏻
In case you read it, 2 things I would like to especially bring to your attention:
(1) the role of 'access modalities' in the draft delegated act
(2) the potential of single-blind non-public data access in the future
Let know what u think
Our second newsletter is out now! This time we cover:
📃 the draft delegated act on data access
⛔ known issues around public and non-public data access
🗳️ election interference as a risk in focus
and
📜 other developments around the DSA

The Twitter exodus has started, but maybe it should have started long ago?
Our new study in @NatureComms shows that political abuse on X is a global, widespread, and cross-partisan phenomenon

I think we have to realize that we have entered a new phase (perhaps not so new in some countries) that has moved from collateral damage from the attention economy to active manipulation of public discourse....
Together with @MarkAndrejevic we have just published compelling evidence that @elonmusk’s posts are being algorithmically boosted.
Read about it in this article, just published: theconversation.com/tech-bil…

Can we just ditch the delusion that social media platforms are “neutral” carriers? One wonders how much Musk stacked the information war in his favour on this platform… but then no one seems to care because (a) it’s obvious and (b) what can you do

Latest from me in MANAGER MAGAZIN on Elon Musk and X as a political tool for winning elections
(It's in German so here's a thread with some observations)

@EU_Commission launched recently a public consultation on the draft delegated act on access to online platform data for vetted researchers under the #DigitalServicesAct (#DSA). I'm attaching highlights and comments of @Lorenz_Spreen, which include a few of my own replies.👇
Out now in PNAS and led by the amazing @Abdulshir with a great team from @arc_mpib @mpib_berlin, our systematic meta-analysis of individual factors for misinformation susceptibility:

Please read this. It's literally been 8 years in the writing.
The first wave of tech disruption of democracy 2016-2024 is over. What starts now is something much, much worse: the age of information chaos.

Ich kann allen nur empfehlen, zu Bluesky zu wechseln & zB dort aktiver als hier auf X zu diskutieren: U.a. weil der Ton auf Twitter seit der Übernahme durch konstant aggressiver wurde & weil seit der US-Wahl erneut Dämme gebrochen sind, welche Aggression hier ausgedrückt wird
