Study of trust in science in 68 countries finds Australia is the #1 high-income country for trust in science www.nature.com/articles/s41... (only Egypt, India, Kenya, and Nigeria were ahead)

New Replication Project in sport and exercise science shares it results: Out of 25 replication studies performed, 56% yielded significant results, but only 7 (28%) revealed a similar effect size. Several problems related to the quality of are discussed. link.springer.com/article/10.1...

Paper is finally up and open access (www.journals.uchicago.edu/doi/10.1086/...), it's a sequel to an earlier paper where we'd argued that there's not good evidence that pre-publication peer review is a net benefit (www.journals.uchicago.edu/doi/10.1093/...). So in this one we suggest an alternative.

Hindawi disappeared, I didn’t know. Glad I don’t have papers with them given the reasons they disappeared 😅. Confirms we should think twice before deciding where to publish our work.

This great editorial clearly explains the Peer Community In (PCI) initiative. It’s from @psych.peercommunityin.org, but it applies to all PCI communities: doi.org/10.31234/osf...

Being Chair of a department in academia -- A thread of "Congradolences" and "Condoltulations" 🤣 Feels familiar 😅

Can you make it easier than "the probability of getting results at least as extreme as the ones you observed, given that the null hypothesis is correct"?

A fascinating behind the scenes view of #metascience projects, from the funding side. Like Ruben, I missed it when it came out, but it's well worth a read.

An important point missing from this piece is that it's harder to p-hack one's way to small p-value. Which I think means that even if all that happened is sample size increased and attempts at p-hacking had remained constant, their chance of resulting in headline false results is lower.

This project has taken what feels like a thousand hours this year. It's nearly done... #brainstim #TMS #metaanalysis

The proportion of p-values between .01 and .05 declined in psychology over the last decade, a strengthening of credibility. Papers with fewer fragile p-values are cited more. Higher ranked journals assoc. with > improvement, but not higher ranked universities. journals.sagepub.com/doi/10.1177/...

MRI brain correlates of approach-avoidance tendencies toward sitting, standing, and running. Led by @bcheval.bsky.social. Published in Imaging Neuroscience @imagingneurosci.bsky.social, a university press journal committed to support academia and robust research practices. doi.org/10.1162/IMAG...

I really like this one! The benefits of physical activity are similar whether you’ve started late in life or you’ve been active your whole life. doi.org/10.1001/jamanetworkopen.2019.0355

I am beginning to understand where this common confusion/disagreement comes from (see posts & discussions below). I would *love* (in a very nerdy way) to read about this confusion somewhere, but no relevant papers seem to have been suggested yet... Maybe you have one for me..? 🙏

If you are a coauthor, suggestions to address your own comments on the manuscript will always be appreciated.

Percentage of researchers who engaged in a questionable research practices (QRPs) at least once. It's self-reports, so I guess it's even more than that. lakens.github.io/statistical_...

47.6% of people who intended to be physically active failed to translate this into action. doi.org/10.1136/bjsp...

When running ANOVAs in #R, use car::Anova(). aov() and anova() use Type I sums of squares, meaning that order matters, which can distort results in unbalanced designs. car::Anova() is safer because it uses Type II sums of squares by default), each effect is adjusted for all the other effects.

I submitted 4 of my latest papers to Physiotherapy Canada because it’s a University Press, supported by the 🇨🇦 PT association @physiocan.bsky.social, & my library said their subscription was cheap. Result: Excellent experience, thorough peer reviews, good reactivity to emails. That’s all I ask for.

I urge folks to sign this letter and share it with their university colleagues to get critical mass.

Do you post or read preprints on bioRxiv and medRxiv? Then you might want to learn about openRxiv, an independent, nonprofit framework created to provide sustainability and governance of bioRxiv & medRxiv

Meta-analysis forest plots begin to look too crowded if you're reporting around 50 effect sizes or more. This 'orchard plot' is a really nice alternative for visualising 50+ effect sizes (paper link: doi.org/10.1111/ele....). Can anyone point me to other similar visualisations that they like?

Fear of movement (kinesiophobia) and physical activity. A meta-analysis now in @ptjournal.bsky.social. doi.org/10.1093/ptj/...

PeerJ is now part of a large for-profit commercial publisher. Sad 😶. peerj.com/blog/post/11...

I’m cutting in the flesh of my manuscript to meet the word count limit imposed by the journal while addressing the reviewers’ comments, putting so much info in the suppl. material. Honestly, I think the preprint version will be better than the journal version.

Cool paper in AMPPS of @psychscience.bsky.social "One App to Rule Them All: A One-Stop Calculator and Guide for 95 Effect-Size Variants for Two-Group Comparisons of Central Tendency, Variability, Overlap, Dominance, and Distributional Tails” doi.org/10.1177/2515...

New blog post! In which I explain the issue with mediation analysis and sketch out one way to deal with the underlying causal inference problem -- in just a bit over 1,000 words! If you have never found the time to read up on this, now is your chance. www.the100.ci/2025/03/20/r...

Tens of thousands of psychological measures have been created, but 79% are not reused more than twice. In a new article in NHB lead by @faridanvari.bsky.social and @ruben.the100.ci we quantify this fragmentation in psychology's measures and propose solutions. www.nature.com/articles/s41...

Pet peeve: I hate how often ppl claim “all the researchers will just move to Europe/Canada!” You vastly under-estimate how little money there is there vs the USA- and unless that changes ASAP this loss is just going to decimate global science, full stop. 🧪🔭

🚨 HUGE news from Canada's tricouncils who are harmonizing their scholarship & fellowship programs, upping the total number (huzzah!), and critically, allowing foreigners to apply for doctoral and postdoc fellowships. Want to work with me? Get in touch! 🇨🇦🧪⚒️ www.nserc-crsng.gc.ca/NewsDetail-D...

Big news: we are setting up a new non-profit organization to run bioRxiv and medRxiv. It's called openRxiv [no it's not a new preprint server; it's dedicated organization to oversee the servers] openrxiv.org 1/n

We are delighted to now be part of the Free Journal Network, a community of free-to-read and free-to-publish journals like ours! freejournals.org/current-memb...

Clinicians & rehabilitation assistants are not immune to attitudes against people with disabilities. Implicit attitudes of healthcare practitioners were not more favorable than those of other occupations & explicit attitudes of clinicians were even less favorable. #ableism doi.org/10.1101/2025...

1. Today the NIH director issued a new directive slashing overhead rates to 15%. I want to provide some context on what that means and why it matters. grants.nih.gov/grants/guide...
