For four years, AI has reigned supreme – and lots of news organisations have jumped on the bandwagon/caught on/thought deeply about how they, too, could make use of it. What do they (want to) use it for? Increasingly for content creation. Full post here: open.substack.com/pub/felixsim...

New paper with @sachaltay.bsky.social! A lot of people think AI can only make science worse. We argue agentic AI can actually be a great tool to do it better!

AI agents are valuable epistemic tools. They let us look under the hood of scientific research, lowering the cost of verifying (and implementing) good methodological practices. With @edgardubourg.bsky.social, we propose a step-by-step method for using them. osf.io/preprints/ps...
