If you currently do not have a reproducible workflow where you can share data and code where possible, I expect you will soon not be able to publish in good journals.

Beyond being best practice, journals will use this to identify papers written by AI.

Plan a new project accordingly.

Using test data from TwinLife (N=9,980, Culture Fair Test CFT 20-R), we show that Regularised Prediction and Poststratification yields IQ scores that differ by up to 19 IQ points (mean 4.19 pts) from those reported in the CFT 20-R manual

Just read the abstract 🫠 via Alexander Magazinov. I don't believe he is on Bluesky.

Clearly we're just twin intellectual flames!

Here's to a radical future where openly-available IPD is the default!

Clinical trial reforms that once seemed radical How randomized controlled trials, preregistration, and results reporting became standard practice.

New post!

It may seem ambitious to ask for individual patient data from clinical trials to be shared, anonymized, for use by other researchers.

But the history of medicine shows us that clinical trials have already undergone a series of transformations that once seemed equally bold:

Two new papers from the lab on research practices in security & privacy research: 1) Reliability of measures and the use of Cronbach's α osf.io/preprints/ps..., 2) Practices around retraction and correction notices by ACM and IEEE (osf.io/preprints/ps...)

A propos of nothing, that IT response feels very ChatGPT

Should everyone be taking statins?

New episode of HARD DRUGS!

Should everyone be taking statins?

Statins have revolutionised heart disease and they're one of many reasons for the long-term decline in cardiovascular mortality.

Why do I have to pretend that I'm going to print something in order to save it as a PDF. Why do I have to engage in a little ruse.

OpenSAFELY news: you can apply to do non-COVID research, from today! | Bennett Institute for Applied Data Science We are delighted to announce that - from today - you can submit applications to the OpenSAFELY service for non-COVID-19 studies.

OpenSAFELY is open from today! Huge thanks to all who supported this vast collaboration: whole population GP data; in a productive platform; innovative privacy protections; unprecedented support from professions, privacy campaigners; &c

Now it's over to users!

We regret to inform you that your paper cannot be considered for publication, but we encourage you to submit it to our GOLD Open Access sister journal

We have something quite related in the works!

The latest episode of our @bpsofficial.bsky.social @researchdigest.bsky.social podcast PsychCrunch.

We took a different approach to this one, and I'm really grateful to @maddipow.bsky.social @richardwiseman.bsky.social @margaritap.bsky.social @jamiecummins.bsky.social and others for contributing.

Economists!

I am looking for someone to coauthor an article on the massive decline in costs of genome sequencing.

The science is all fine, but I'm interested in the economics of it all: the innovation, funding, prizes, patents, etc.

Does anyone come to mind? Thanks!

Thanks Alexander! I'm always happy to hear about how you use it in the future & whether you notice anything that could be improved.

Just used this (very interesting!) paper as an example to try out RegCheck v2 for the first time.

RegCheck.app by @jamiecummins.bsky.social et al. is an OpenSource LLM-based tools to compare a published study against a replication plan. All the usual LLM caveats apply. But seems pretty useful.

thanks so much for the share Tiago 🫂

Really nice piece on @psychmag.bsky.social by @jamiecummins.bsky.social this month!

Thanks for writing this Jamie! 👌🏼

📣 New preprint!

We brought together experts from academia, major video game studios, NGOs, funding bodies, and civil society groups to ask: what should be prioritised when it comes to the future of video games? 🧵

Aligns with some of our experiences too. Hopefully our paper can help folk to reevaluate some of their own squeamishness

3. Generating clearer inputs for downstream tools

Imagine you're in a world in which LLMs play an increasingly larger role in research. Tools like RegCheck screen for compliance against pre-analysis plans. It may all the more important to ensure that your plans are clearly documented. 6/

I've built a new tool!

You can upload your pre-analysis plan or registered report, pre-submission to a registry or journal, and it will screen it for completeness, clarity, and consistency. 1/ 🧵

This is a no-brainer. Metascience is not accountable if it is not transparent about the research that it uses or critiques.

Should meta-science articles hold themselves to the same standards of transparency and reproducibility that the field prescribes for others?

We think so.

New preprint and 🧵

Meta-scientists cannot demand transparency from scientists while failing to meet those same standards. In this paper we make one simple recommendation: meta-scientific data should be deanonymised by default.
