Although a meta-analysis of 148 samples from over 8000 participants reported a weak correlation between brain size and IQ, [22] men and women did not differ in IQ, and the researchers concluded that "it is not warranted to interpret brain size as an isomorphic proxy of human intelligence differences."
The following is a list of living centenarians (living people who have attained the age of at least 100 years) known for reasons other than just their longevity. For more specific lists of people (living or deceased) who are known for these reasons, see lists of centenarians.

Norwegian epidemiologists used military records to examine the birth order, health status, and IQ scores of nearly 250,000 18- and 19-year-old men born between 1967 and 1976.
IQ Range ("deviation IQ") IQ Classification (Theoretical) Percent Included 128 and over Very Superior 2.2 120–127 Superior 6.7 111–119 Bright Normal 16.1 91–110 Average 50.0 80–90 Dull normal 16.1 66–79 Borderline 6.7 65 and below Defective 2.2
In men the average weight is about 1370 g and in women about 1200 g. [4] [contradictory] The volume is around 1260 cm 3 in men and 1130 cm 3 in women, although there is substantial individual variation. [5] Yet another study found that adult human brain weight is 1300–1400 g for adult humans and 350–400 g for newborn humans.
The size of human beings has increased over the past century thanks to better health and nutrition — but this change has not occurred equally among men and women, a new study shows.
Taking into account measurement quality, and sample type and IQ-range, the meta-analytic association of brain volume in appears to be ~ .4 in normal adults. [15] Researcher Jakob Pietschnig argued that the strength of the positive association of brain volume and IQ remains robust, but has been overestimated in the literature.
