According to the 1994 report "Intelligence: Knowns and Unknowns" by the American Psychological Association, "Most standard tests of intelligence have been constructed so that there are no overall score differences between females and males." Differences have been found, however, in specific areas such as mathematics and verbal measures.[9]
When standardized IQ tests were first developed in the early 20th century, girls typically scored higher than boys until age 14, at which time the curve for girls dropped below that for boys.[8][10] As testing methodology was revised, efforts were made to equalize gender performance.[10][11][12]
The mean IQ scores between men and women vary little.[9][13][14][15][16] The variability of male scores is greater than that of females, however, resulting in more males than females in the top and bottom of the IQ distribution.[17]
