Males and females tend to have the same average intelligence test scores. They differ in some specific abilities.
Girls are better spellers, more verbally fluent, better at locating objects, better at detecting emotions, and more sensitive to touch, taste, and color.
Boys outperform girls at spatial ability and related mathematics, though boys and girls hardly differ in math computation. Boys also outnumber girls at the low and high extremes of mental abilities.
Psychologists debate evolutionary, brain-based, and cultural explanations of such gender differences.
Racial and ethnic groups differ in their average intelligence test scores.
The evidence suggests that environmental differences are largely, perhaps entirely, responsible for these group differences.
Aptitude tests aim to predict how well a test-taker will perform in a given situation. So they are necessarily “biased” in the sense that they are sensitive to performance differences caused by cultural experience.
By “inappropriately biased,” psychologists mean that a test predicts less accurately for one group than for another. In this sense, most experts consider the major aptitude tests unbiased.
Stereotype threat, a self-confirming concern that one will be evaluated based on a negative stereotype, affects performance on all kinds of tests.

Scores on tests of mental abilities vary by race.

cultural background has little influence on test scores.
scores on the test are not very stable even when you don’t consider race.
