Excited to share a paper recently accepted at Nature Mental Health! 😄 For decades, we've assumed that covariance among psychopathology informs comorbidity. What if we’ve been wrong?
Covariation among higher-order psychopathology dimensions is driven by nomorbidity, not comorbidity: https://osf.io/3t2cm

What matters most for childhood brain organization? We analyzed 649 variables. The answer: Socioeconomics (SES); with brain patterns pointing at sleep & stress as drivers. Even brain-IQ associations were better explained by SES. In Science today: www.science.org/doi/10.1126/...
It’s worth the time to read, and it’s worth the time to comment. No, it’s not completely futile.

Absolutely terrifying. This would completely destroy American scientific research.
Some time ago I wrote a non-technical introduction to marginal effects, in case you don't know the underlying logic yet. The idea is to use your model as a prediction machine that can be queried to return answers to precisely the questions you're interested in. www.the100.ci/2022/05/27/%...

External validation is a great way to improve rigor in neuroimaging. Although a simple idea is simple—test a predictive model on another dataset—the practice is not. In our Perspective in @natmethods.nature.com, we discuss practical issues and solutions; www.nature.com/articles/s41...

This Perspective promotes the use of external validation using independent datasets for human neuroimaging studies.

So glad to finally share work years in the making! What started with fMRI effect size benchmarks ended up showing that conventional study planning detects ~half of expected brain effects, suggesting more distributed processes than the lit shows (+ new methods for mass univ effect/power estimation)
When conducting peer reviews, I increasingly think about the time & workload demands of my suggestions. If there's a flaw that needs correcting, then it needs requesting. But if I just have a preference, something that I think would 'improve the paper', then do I really need to request it?
omg just made a table describing my sample demographics with the gtsummary r package and it was SO EASY and i did not need to fiddle with microsoft word table formatting at all and i am so mad i didn't know about this sooner so consider this a PSA in case you also didn't know
Very excited about this project, led by @zachladwig.bsky.social We show that an individual’s lateral prefrontal cortex has reliable and highly detailed network organization missed in past group approaches. Full🧵 coming soon!
