Thorndike reports the general results of such tests as follows:

The percentages of males reaching or exceeding the median ability
of females in such traits as have been subjected to exact investigation
are roughly as follows:

In speed of naming colors and sorting cards by color and
discriminating colors as in a test for color blindness 24
In finding and checking small visual details such as letters 33
In spelling 33
In school "marks" in English 35
In school "marks" in foreign languages 40
In memorizing for immediate recall 42
In lowness of sensory thresholds 43
In retentiveness 47
In tests of speed and accuracy of association 48
In tests of general information 50
In school "marks" in mathematics 50
In school "marks" (total average) 50
In tests of discrimination (other than for color) 51
In range of sensitivity 52
In school "marks" in history 55
In tests of ingenuity 63
In accuracy of arm movements 66
In school "marks" in physics and chemistry 68
In reaction time 70
In speed of finger and arm movement 71

The most important characteristic of these differences is their
small amount. The individual differences within one sex so enormously
outweigh the differences between the sexes in these intellectual
and semi-intellectual traits that for practical purposes the sex
difference may be disregarded. So far as ability goes, there could
hardly be a stupider way to get two groups alike within each group
but differing between the groups than to take the two sexes. As is
well known, the experiments of the past generation in educating
women have shown their equal competence in school work of elementary,
secondary, and collegiate grade. The present generation's experience
is showing the same fact for professional education and business
service. The psychologists' measurements lead to the conclusion
that
