“Dutch people cycle an average of 2.6km each per day. If this pattern was replicated worldwide, annual carbon emissions would drop by 686 million tonnes.

This mammoth figure exceeds the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia and Australia.” @euronews.com
Cycling like the Dutch would slash the world’s carbon footprint
If everybody cycled like the Dutch, we could offset the UK or Australia’s entire carbon footprint.

So, folks might recall the great BMR series of articles from the MacroFactor team last year. One of the articles tackled the challenges women with polycystic ovary syndrome (PCOS) face with respect to managing their weight, and claims that this is in part due to "slower metabolism"

Just had our first set of reviews from @pci-regreports.bsky.social for our proposed study on RT during GLP-1-RA treatment.

Probably the most constructive and useful set of reviews I have ever had... and having them before starting the study makes them even better!

Metacheck can now automatically 1) download a preprint from PsyArXiv, 2) create a report of the checks (stats, reporting guidelines, references, code, etc), 3) retrieve the authors email, and 4) send them the report.

Would you as an author appreciate this? When yes, when no?

We just preprinted a huge meta-meta-analysis examining the effects of exercise on cognition, memory, and executive function

In short
- 2239 effect sizes
- extreme between-study heterogeneity
- extensive publication bias
- some subgroup/exercise-specific effects

No industry is perfect. But the imbalance is hard to miss. One sector must prove its products are safe & effective. The other profits by avoiding that responsibility.

I recently discovered Conventional Comments (conventionalcomments.org) for providing a pseudo-standard set of labels for feedback and just tried it for an article review and it was really helpful to specify issues vs. thoughts vs. suggestions, etc. Hopefully it's helpful for the authors too!

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >
