Hi bluesky! I was wondering whether you know of any papers that discuss how much easier it is to do a replication study with agentic AI (eg Codex/Claude Code). In the absence of code, it seems like that's a great way to test whether the models reported in a paper were the ones that were fit, etc.

Likewise!

Yay! QUADAS-3 is out!
🔬🧪
Are you planning to do a systematic review of diagnostic test accuracy? Then check out today's Annals of Internal Medicine for QUADAS-3 and its E&E document!

Changes to QUADAS-2 domains and focus on “ideal test accuracy trial”.

Exploring interdisciplinarity – raising self-awareness through a comprehensive research assessment - MetaROR

For the University of Helsinki's comprehensive research assessment, researchers designed a dedicated module to capture interdisciplinarity.

Reviewers called their approach "inspiring" and did not identify major weaknesses, but do provide recommendations.

Striking paper from researchers at Anthropic using a randomised control trial to look at the effects of AI use on skills acquisition.

TL:DR ‘We found that using AI assistance led to a statistically significant decrease in mastery.’

AI is not a peer, so it can’t do peer review If we still believe that science is a vocation grounded in argument, curiosity and care, we can’t delegate judgement to machines, says Akhil Bhardwaj

'to treat peer review as a throughput problem is to misunderstand what is at stake. Review is not simply a production stage in the research pipeline; it is one of the few remaining spaces where the scientific community talks to itself.' 1/3

The FORRT Replication Database has received a massive overhaul (FReD 2.0): We double-coded and validated all data from scratch and extended it in the course of a one-year-partnership with the @cos.io. We just switched to a faster interface thanks to @lukaswallrich.bsky.social’s wizardry.

Reproducibility and open science are great, but they don't necessarily equate to rigor. You can perfectly share a study and still draw weak conclusions. True rigor lives in the questions we ask, the designs we choose, and the inferences we make.

Poster for an online course on epidemiology for journalists

Course recordings and slides are still available as a free resource on my teaching website

Thanks for the update! It remains a nice go-to list when I am looking for something to read.

Recently, I read 'In het oog', by Marijke Schermer. The scientific part and the underlying motives are not so strong, I thought. But it was a nice read.

LLM use in scholarly writing poses a provenance problem Nature Machine Intelligence - LLM use in scholarly writing poses a provenance problem

Suppose you ask #AI for improvements to your writing.

The #LLM was trained on, but doesn’t mention, Smith’s work.

You adopt the suggestions containing Smith’s ideas.

You don’t even realize YOU’VE PLAGIARIZED because you’ve never read or heard of Smith.

It is not just that 'ideally' criteria for publication should be the same for significant and non-significant results - it is literally in the code of conduct for research integrity. If you do not act in line with this, you are violating the code of conduct for research integrity.

Always felt the lone outsider when claiming that the use of AI is in many instances really not faster than doing it yourself. Happy to see this backed up by others.

Also: what is the problem with just enjoying thinking and writing? Why would I leave that to AI?

“It accidentally replicated the linguistic ghost of the British Empire.”

This is an important piece of writing.
