@HeblingVieira For our purposes, conceptualizing the brain as a mediator is more reasonable (though the manuscript was rejected by several top-tier journals). By analogy, in lung cancer research, one would expect a biomarker to mediate the relationship between smoking and cancer.
We did the mediation analysis you mentioned, published 4 years ago. [SES->Brain->IQ].

@ndosenbach@smarek0502@DrDamienFair@ScienceMagazine Does the result allow one to distinguish between the confound model (IQ <- SES -> Brain) and others, e.g., the mediation model (SES -> Brain -> IQ)?
@HeblingVieira btw, Sripada group also did a similar mediation, focusing mainly on rs-fMRI too.

Brain-wide functional connectivity patterns support general cognitive ability and mediate effects of socioeconomic status in youth
You can’t infer cognitive abilities by simply looking at someone’s brain. But by “stacking” MRI data from many tasks and from brains at rest, AI can predict cognitive abilities with reasonable accuracy. In PNAS Nexus: https://t.co/22CV0Fa7H4
This work has now been published at @PNASNexus.

@Alina_T_Brain just gave a talk on this at @OHBM's Neuroimaging Statistics Workshop.
I will touch on this in my talk at @TheRealSPR under the Big Idea symp, in October 15–18, 2025, Montréal, Canada.

Excited for Pat's lab's first @OHBM conference—glad it's happening in this part of the world! We’ve got 1 talk & 5 posters lined up (see below). See you next week in Brisbane! Also, we're recruiting PhD students & a postdoc for a multi-site project across Aotearoa NZ
Want to move to beautiful New Zealand? The Department of Psychology at the University of Otago is hiring a new clinical psychology faculty member. (Lecturer = Assistant Professor in North American system). Feel free to contact me with any questions!

Great job students and faculty of the International Statistical Genetics Workshop 2024 in Boulder at @IBG_CUBoulder, what an amazing week as always 🧬❤️
Next year it's GWAS and sequence data analysis again, see you then: https://t.co/rRKyrkqAzf
