Yes, and it is done. The APA has done several exhaustive studies showing that the IQ differences in races in the US is not based on test construction or administration.

This is a hot political issue. Here is a summary article, however, it is showing some passionate bias. There are many others, but I could not find any better at summarizing the issue.

Yes, there have been efforts to revise IQ tests in order to reduce cultural bias. One approach is to develop tests that rely less on language and cultural knowledge, and more on abstract reasoning and visual-spatial abilities. This can be achieved by using nonverbal or performance-based tasks, such as solving puzzles or completing patterns.

To revise IQ tests and reduce cultural bias, researchers also take into consideration the diversity of experiences and backgrounds within the test-taking population. They strive to include a wide range of examples and references that are more universally understood and relatable.

Another important aspect of revising IQ tests is ensuring that the items are equitably challenging for individuals from different cultural backgrounds. This involves conducting extensive research and analysis to determine whether certain test items disproportionately favor or disadvantage particular cultural groups. If bias is identified, the items can be modified or replaced with alternatives that are more neutral or fair.

The goal of these revisions is to create more culturally fair IQ tests that accurately measure cognitive abilities across diverse populations. However, it should be noted that eliminating cultural bias entirely from IQ tests is a complex and ongoing process, as cultural influences are pervasive and can be difficult to completely eliminate.
