If we define intelligence as IQ then the evidence is overwhelming that the average differs among races. Even in Singapore, which has a very high standard of living, nutrition etc., we still see Chinese Singaporeans perform significantly better than Malay Singaporeans on various measures of intelligence, with Indian Singaporeans somewhere in the middle. The same pattern is seen among Chinese, Indians and native Malaysians in Malaysia, and globally when we compare the mean IQ scores of China, India and Malaysia.

That could also be explained by cultural differences, I don't think the evidence is overwhelming.

Or it could be discrimination. There are studies that show that black and white mixed races children did not score any higher than children with two black parents, while white people score higher than black people on average, which may point to some discrimination impacting IQ.

Discrimination against whites in favor of blacks doesn't lower white IQ.

		We know that discrimination, even between whites, has a negative impact on test scores. It seems like discrimination can hurt people's performance, but the type of discrimination, how impactful it is on the people being discriminated against, and the extent to which it happens over the population probably matters.

There are significant cultural and economic differences between those communities. These will be similar between Singapore and Malaysia. The Chinese and Indians are sufficiently recent immigrants for their culture to still have a lot in common (they speak the same language, follow the same religions, have inherited attitudes) with the places their ancestors came from.

		If the difference is due to culture (and not genes), then the conclusion would be that Malay culture is bad and should be oppressed, right? If the difference is genetic then Malay culture gets a free pass.

		> There are significant cultural and economic differences between those communities. And where does culture and/or economy come from if they don't come from races of people? Do hackers argue that human culture existed before humans?

No, you mean to say "if we define intelligence as the output of IQ testing", which clarifies that you're projecting from statistical surveys (with all sorts of potential confounders) rather than some directly queryable and innate attribute of people.
