People's IQ is Determined by the Size of the Head!
Jeremy Genovese, an associate professor of human development and educational psychology at Cleveland State University, insists that the link between head size and IQ may be minimal but it does exist.
"The correlations between head size and IQ are quite modest, and you cannot determine someone's intelligence with a tape measure. However, the correlation is real and might have some clinical significance, such as predicting susceptibility to dementia," Discovery News quoted him as saying.
He, however, said that though "larger bodies do require larger brains to support larger nervous systems," the notable difference in body size between men and women appeared to have "no relationship to intelligence."
For the study, Genovese obtained copies anthropological and sociological records on roughly 12 percent of on roughly 12 percent of American prison inmates in 1939 study, collected by Harvard anthropologist Earnest Albert Hooten.
Since IQ tests had already been performed on the 676 male inmates at the Concord Reformatory in Massachusetts, Hooten had documented their head circumference, head length, head height and even head shape.
Genovese said that he used statistical computer software to find patterns hidden from Hooten, considering the more limited methods of his day.
He revealed that he did not find any evidence showing an association between a rounder head and greater intelligence, as many scientists often claim. However, the analysis enabled him to confirm Hooten’s suggestion that there exists a connection between head size and intelligence.
