🚨 New preprint: In this paper we make the case for measuring social media use at the level of naturally occurring sessions (i.e., beginning when the app/site is opened and ending when it is closed). Across 7 days and 161 participants this gave us nearly 4,000 paired sessions of use 🧵

Depicts the data collection process. 1) participant opens TikTok, 2) open survey is prompted, 3) participant uses TikTok as normal, 4) participant closes TikTok, 5) close survey is prompted

🚨Update: Our analysis of global APC expenditure has now been expanded to cover more publishers (7 -> 14) and more years (2019-2025). We estimate $15B in APCs paid over seven years, $3.7B in 2025 alone. Elsevier crosses the $1B threshold by itself in 2025. arxiv.org/abs/2608.16322 #ScholComm

🚨 Preprint! We combine our recent open dataset of #APC prices with the article counts per journal-year from #OpenAlex to estimate how much the academic community has paid in APCs over the last 5 years. A. $8.349 billion ($8.968 B in 2023 USD) $2.5B in 2023 alone. arxiv.org/abs/2407.16551 #metasci

What are some examples of *non-fraudulent* major errors in scientific papers that had major consequences, perhaps after taking a long time to be corrected?

I’m still gathering papers, so this is a call to my social media research colleagues 📣: if there’s a paper you find especially interesting, informative, or thought-provoking (yours or someone else’s) please pop it in the comments or email me sabrina.norwood@unibe.ch!

I’ve been told for years that it’s legally and ethically impossible to share medical RCT data. In 2024, the BMJ made sharing anonymised data mandatory, and now lots* of folk do it. Interesting how the barriers evaporated like that, isn’t it? *not everyone, compliance problems exist.

Availability of clinical trial individual patient data in the BMJ before and after adoption of a stringent data-sharing policy, compared with recent rates at other major medical journals

Background In 2024, the BMJ updated its data-sharing policy for clinical trials, requiring open deposit of deidentified individual participant data (IPD) before publication. We considered whether data...

There’s a scene in Succession after Tom has been put in charge of Cruises, and he goes to Ken to make him aware of the serious problems at the department. And Ken is like ‘I do not want to know about this. It is your job to make sure I don’t find out.’ A lot of PIs are like this.

Any suggestions for semi-popular online chi-square calculators? Sometimes less experienced people use them. To validate my {recalc} package, I'm reverse engineering them to make sure the package accommodate their results, as long as they're correct and sane. These are the ones I have already.

Over the next several months, we will phase out some popular OSF features. These changes do not affect current public content, which remains safe and accessible. We have prepared support material to help users adapt. I am very sorry for the disruption to your work. Please read this post for details.

OSF Changes | Center for Open Science

We are preparing substantial changes to OSF that will reduce its functionality, focus OSF on its unique strengths, and move toward an integrated model with complementary services. As part of that shif...

New Jingle assessment: we show that the "Perspective Taking Protocol" has very poor reliability and near-zero convergent validity with other nominal measures of emotional and spatial perspective taking, empathy, and theory of mind. w/ @malte.the100.ci

Sobering: initial trials with huge effect, large follow-up trial showing no evidence for an effect. But practice is already locked in and criticism is defused by pointing to random effects meta-analyses which are necessarily dominated by the initial trials. polypharmacy.substack.com/p/we-should-...

We should stop running clinical trials that cannot change practice
