195: Living meta-analysis

We're back! After a long break, we catch up on why it's been so long: Dan's promotion and James's new venture capital gig at Helena where he can argue about science for a living. Then it's on to how much meta-science has changed in the past six months. Dan talks about using MetaCheck and local LLMs to find out whether shared materials on OSF actually get downloaded (mostly yes) and James argues that reanalysing public data is now so cheap it barely counts as a paper. We also get into why real human data is gaining value, how to disclose AI use (Disclosure: AI was used to help create these notes, based on the recording), and why open-weight models at "temperature zero" make reproducibility of LMM output easier. We also cover the worry about outsourcing thinking, what LLMs mean for grants, and why data provenance is going to matter.

We discuss how living meta‑analyses—meta‑analyses that are continuously updated as new studies appear—can cut research waste and keep evidence current. We also chat about how using synthetic research participants is a terrible idea.

We discuss whether preprint servers and journals should require author identity verification for submitting manuscripts. This would probably speed up the submission process, but is this worth the potential downsides? We also discuss the similarities and differences between academia and professional sports and a weird case of author identity theft.
