A positive relationship between brain volume and intelligence has been suspected since the 19th century, and empirical studies seem to support this hypothesis. ...
Size matters, after all: Bigger brains are associated with higher intelligence. (Large-Scale Preregistered Study)
Are Bigger Brains Smarter? Evidence From a Large-Scale Preregistered Study (N = 13,608)
~5-minute cognitive ability measure correlates .2 with MRI brain volume (n>13,000 uk biobank), mostly driven by gray matter. Nice paper from
