- Reposted by Stefan HerzogWe have published a new short video of a series on hybrid collective intelligence from the HACID project. In this video, we introduce the field, discussing how human experts and AI systems can join forces to produce better solutions to complex problems. youtu.be/3dwGpLo0EE0

- Reposted by Stefan HerzogI just want people to remember that what this was was transparently obvious at the time and universally condemned. Hold on to that fact and don't let people change it under you.

- Reposted by Stefan Herzog🚨 New in Nature+Science!🚨 AI chatbots can shift voter attitudes on candidates & policies, often by 10+pp 🔹Exps in US Canada Poland & UK 🔹More “facts”→more persuasion (not psych tricks) 🔹Increasing persuasiveness reduces "fact" accuracy 🔹Right-leaning bots=more inaccurate

- Reposted by Stefan HerzogCan large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

- Reposted by Stefan HerzogWenn Linksextremismus so ein großes Problem ist, sollte man sie in die Talkshows einladen, mit ihnen diskutieren und ihre Forderungen selbst umsetzen, um sie politisch zu stellen. Oh? Zu fahrlässig? Warum ist das dann unsere Strategie bei der AfD?
- Reposted by Stefan HerzogSachen gibt's: Wenn man die Skalierung der Achse ändert, ist auf einmal der Balken beim Linksextremismus länger.
