So if performance is our outcome and training our exposure, we have something like
training -> performance -> Olympian
And we have
Training <- other stuff -> Olympian
So if we condition on Olympian, we open a back door between Olympian and training

Was kinda forced by circumstance into switching to an iPhone after being a bit of an apple hater for almost 20 years... I hate to say it but, I kinda like the iPhone 17.

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.
I will record lectures & all will be found at this link: github.com/rmcelreath/s...

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"

I've been exposed to enough peer review that I think we can look at two classes of reviewers:
1. Constructive peer review
2. Adversarial peer review
I'm looking at this mostly from a psychology/methodology perspective (but wonder what other fields experience)

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!
11/10 would recommend!

I saw someone post a critical take on the consumer reports protein and lead piece a while back but I can't find it.
For some reason I vaguely recall it being @scientificdiscovery.dev but I can't find it on your feed.
Does anyone remember this?

Sometimes I think the best indicator of whether your field of research is in so called "crisis" is if, when you look around, you come away thinking "jfc... people are doing shitty work in this field" 😅

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

I don't know how I've missed it because it's *right on the documentation home page*, but if you use {glue} for nice string interpolation in #rstats and you have {stringr} loaded (likely through the tidyverse), you can use str_glue() instead of glue::glue() or loading library(glue) glue.tidyverse.org
