Are Bigger Brains Smarter? Evidence From a Large-Scale Preregistered Study (N = 13,608)
Brain size predicts intelligence in a large-scale pre-registered study.
Size matters, after all: Bigger brains are associated with higher intelligence. (Large-Scale Preregistered Study)
~5-minute cognitive ability measure correlates .2 with MRI brain volume (n>13,000 uk biobank), mostly driven by gray matter. Nice paper from lab

Studied to death, but it's nice to have the large sample & preregistration. Hope supplemental materials (can't access them) have the results before controls. Controlling for SES and population has an element of throwing the baby out with the bath water.
