Brain size and cognitive ability: Correlations with age, sex, social class, and race
- PsychologyPsychonomic bulletin & review
It is clear that the direction of the brain-size/cognitive-ability relationships described by Paul Broca, Francis Galton, and other nineteenth-century visionaries is true, and the null hypothesis of no relation, strongly advocated over the last half century, is false.

Prenatal effects are not an important source of bias in twin studies or for heritability estimates based on them, and within-family studies indicated that pleiotropy may contribute to the correlation of intelligence with head size and to the connection with body size.

The results suggest that the size of some cerebral structures may account for a significant, but modest, proportion of the variance in human intelligence.

Analysis of 1,261 adult subjects, ages 25 to 80 years, showed that there is a positive relationship between the brain weight and the body dimensions and that the loss of brain mass proceeds at a slightly faster rate than loss of body mass.
