It was a ton of fun to play a small role in this project lead by the brilliant Marta Ewa Lech & @jonassjuul.bsky.social. A lot of drama & change in the world of music reflected in the song-dynamics of the Billboard Hot 100!

There are two ways to deal with LLMs in our work One is the path of abundance: automate everything and multiply publications at the expense of quality The other is the path of focusing on the soul of the work, on the questions that still matter - to you - when everything else has been made trivial

Looking forward to it!

🚨Are moral judgements biased by the gender of the subject? We find *no* direct effect when looking at Reddit! Our causal study design is based on carefully matching similar situations that people with different genders experience (and share). Study led by @loreb92.bsky.social rdcu.be/eumlQ

Our preprint “How Malicious AI Swarms Can Threaten Democracy” is now online. We show how coordinated multi-agent LLM swarms can infiltrate communities, craft synthetic grassroots “consensus,” and erode institutional trust—and what we can do now to stop it. osf.io/preprints/os...

Nice summary of our latest paper. www.nature.com/articles/d41...

New paper alert. "More is different" & the LLMs. LLMs are usually studied in isolation. But what happens when they start interacting? We explored this by looking at their collective behaviour. Work with @ariel-flint.bsky.social and @lajello.bsky.social 1/

Oral exams are the only true way to assess students - except in specific, marginal cases like parts of Maths or Physics. This has always been true, and we can’t ignore it anymore.

New preprint on the global state of political polarization research 🎉 osf.io/preprints/os... We discuss the many different ways polarization can be conceptualised, how it manifests very differently across countries and domains, and the problems with the dominance of US focused research.

Some people wonder why Musk was a member to begin with. Remember that this is Brittain. The society also has royal fellows: The King of the United Kingdom, The Duke of Kent, The Princess Royal, and The Prince of Wales. Makes perfect sense to also include the real masters of the universe.

Periodic reminder (quite timely this time): using LLMs requires care, but banning them for writing discriminates against non-native English speakers and people with dyslexia - and that’s not acceptable.

Bureaucracy is so powerful that the UK Prime Minister, in a letter to the FT, doesn’t say, “We will cut bureaucracy,” but instead, “We will give you AI to break free from it.” How did we get here? www.ft.com/content/4d44...

who said naming game?

Bureaucracy is killing academia everywhere, it seems..

Your daily reminder of the suffocating grip that bureaucracy has taken on British academia..

Fun fact: Last July, Germany sold ~50k bitcoins (see attached news). Today, those bitcoins would be worth $2 billion more. As the next U.S. administration signals a more crypto-friendly stance, such decisions are set to carry greater political weight. www.thetimes.com/business-mon...
