1) There are cultural differences in how intelligence is viewed and measured. Western cultures tend to view intelligence as an individual's ability to think rationally and categorize, while Eastern cultures see it more as how well one plays their social role. 2) Tests of intelligence developed in one culture may not be effective or fair in other cultures. For example, children in rural Kenyan communities score poorly on academic tests but high on tests of their knowledge of medicinal herbs. 3) Researchers are working to develop intelligence tests that are less culturally biased and account for different types of intelligence valued in various cultures. Effective testing of intelligence across cultures requires understanding the conditions of each culture.
