VCU STUDY SHOWS BIG-BRAINED PEOPLE ARE SMARTER
RICHMOND, Va. (June 17, 2005) – People with bigger brains are smarter than their smaller-brained counterparts, according to a study conducted by a Virginia Commonwealth University researcher published in the journal “Intelligence.”
The study, published on line June 16, could settle a long-standing scientific debate about the relationship between brain size and intelligence. Ever since German anatomist and physiologist Frederick Tiedmann wrote in 1836 that there exists “an indisputable connection between the size of the brain and the mental energy displayed by the individual man,” scientists have been searching for biological evidence to prove his claim.
“For all age and sex groups, it is now very clear that brain volume and intelligence are related,” said lead researcher Michael A. McDaniel, Ph.D., an industrial and organizational psychologist who specializes in the study of intelligence and other predictors of job performance.
The study is the most comprehensive of its kind, drawing conclusions from 26 previous – mostly recent – international studies involving brain volume and intelligence. It was only five years ago, with the increased use of MRI-based brain assessments, that more data relating to brain volume and intelligence became available.
On average, smarter people learn quicker, make fewer errors, and are more productive,” McDaniel said. “The use of intelligence tests in screening job applicants has substantial economic benefits for organizations.”
Before MRIs, scientists often used external skull measurements or waited until a person died to estimate brain size. The external skull measurements were only approximate estimates of brain volume.
