Conflict theory suggests that IQ tests are biased in that they test cultural knowledge instead of actual intelligence. This practice causes underprivileged students to retain a lower status in the society compared to the privileged students. For instance, in order to answer IQ tests on orchestra, one must have the cultural knowledge of music instruments. However, such privileges are only available to students from affluent families with exposure to orchestral music. These tests facilitate the maintenance of power rather than providing equal opportunities to learners.
