Research into IQ tests provide a clear example of ethnocentrism. This is because they have been developed and tested in the western world, based on western views of intelligence, so are not suitable for other cultures. These have been misused to reinforce superiority of western cultures and has led to discrimination in immigration policy and sterilising individuals who do not meet western IQ expectations. However, research has shown that when using these IQ tests, cultural differences in scores do not exist, showing clear culture bias and the damaging consequences of ethnocentrism.
