In 1836, Frederick Tiedmann wrote that there exists
“an indisputable connection between the size of the brain and the mental energy displayed by the individual man.”
(Hamilton JA 1935. The association between brain size and maze ability in the white rat. Doctoral dissertation, University of California, Berkeley.)
Brain volumes can be measured accurately with MRI, and using MRI, research has shown that intelligence and brain volume are meaningfully related. The correlation is higher in adult women. Another study in elderly men showed that fluid intelligence, premorbid intelligence, and visuospatial memory are affected, but not verbal memory and verbal fluency.
It’s OK to be big-headed after all…
