Die Forschungsministerin freut sich auf Insta darüber, dass jetzt "Porträts" von Frauen der Geschichte in ihrem Haus hängen. Nur: Die sind mit KI erstellt. Und schleifen die Gesichter der Frauen gemäß moderner westlicher Schönheitsideale glatt.
Was für ein irres Projekt
Z.B.

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

Marco Buschmann hat die Seiten gewechselt und spielt jetzt für Elmos X.

Mit den üblichen Taschenspielertricks, zB Urteile als "nicht zustellbar" auszutricksen usw

Ich habe KEINE WORTE dafür wie ARMSELIG ich das finde.

Kein Wunder, dass Buschmann gegenüber X zahnlos blieb, als er noch Minister war

Der deutsche Staat verweigert Oskar-nominierten Filmleuten aus Afrika das Visum, um an der Berlinale teilzunehmen, weil das Risiko zu hoch sei, sie würden das Land nicht wieder verlassen. Hier könnte Grosskitschist Wender mal was zu sagen.

„[KI] ist nur dann allgegenwärtig, wenn wir das zulassen“ — this!! Viele Diskussionen gehen von der Prämisse aus, dass wir der Entwicklung ohnmächtig ausgeliefert sind & jetzt alle KI nutzen müssen. Das ist 1 Bankrotterklärung an die Selbstwirksamkeit der Wissenschaftsgemeinschaft. We can do better!

Ich bin für den Wallonie-Weg: Keine Zusammenarbeit mit Rechtsextremen. Keine Sendezeit. Keine Live-Interviews, sondern wenn überhaupt aufgezeichnete Statements mit Faktencheck. Am Beispiel Belgien - im Gegensatz Wallonie-Flandern: Das funktioniert. In D beweisen wir das Gegenteil erneut.

Every instance of "AI democratizes the arts, you're classist and ableist and a gatekeeper for trying to stop it" is a slap in the face to the literally centuries of poor, disabled people making art on the margins and a crass lie in service of a machine that strips down and regurgitates dreams

It breaks my heart, infuriates me, and drives me bonkers every time I think about the art we could have had if, instead of giving Talented Known Predator chance after chance, we had given that space to the women and minorities the industry chased away and abused.

Finds irritierend, dass bei Streiks oft geschrieben wird, es werde eine Lohnerhöhung gefordert. Tatsächlich geht es aber sehr oft vielmehr um eine Inflationsanpassung zwecks Beibehaltung des Reallohns. Das ist ein großer Unterschied. Leute streiken nämlich oft, damit sie nicht weniger verdienen.

When facing an epidemic, decision-makers have to agree on a public health strategy. But what does the public want?

To put it very briefly: Strategies should neither be too lax nor too strict, but it also depends on when and who you ask.

Interesting paper and helpful thread. Bottom line: publicly supported independent media and reducing uncertainty lead to positive cycles; lower quality media and perpetuating uncertainty lead to downward spirals in this Austrian study.

Abstract: How does anti-immigrant rhetoric by mainstream politicians affect norms of tolerance? How does this compare to similar statements made by radical-right politicians? Drawing on experimental evidence, we find that statements by mainstream politicians lead to more norm erosion than similar statements by radical-right politicians. Subsample analyses suggests that this is because statements by mainstream-right politicians erode norm perceptions of right-wing individuals, while those by radical-right politicians induce backlash among left-wing individuals, who hold closer to the norm in place. The latter effect (backlash by the left) disappears when similar statements are made by mainstream right politicians. We argue that this difference occurs because mainstream politicians represent the views of a larger part of the population or have a higher status. Our results highlight the pivotal role of mainstream politicians in enforcing or eroding democratic norms, and that similar political statements can have different effects depending on their sender.

Very happy that our paper (w/ @dziblatt.bsky.social & E Dinas) has been accepted @bjpols.bsky.social .

We've seen the center right increasingly adopt far-right rhetoric.

Our experiment in 🇩🇪 finds that this erodes anti-prejudice norms *more* than when the far-right employs similar rhetoric.
