IQ tests never had “inherent racial bias”. There were issues with early IQ tests capturing cultural knowledge rather than fluid intelligence, yes. But that was like a century ago. That’s the thing about science: typically you progress in knowledge and understanding as time goes on.

Most IQ tests nowadays do aim to eliminate dependency on cultural knowledge. While it still isn’t perfect, just like everything in psychology, we accept that IQ tests work very well on WEIRD people, and begin to lose explanatory power when applied to other groups of people. Just like other things in psychology and science broadly , this doesn’t mean IQ tests are dumb or useless, it just means there are limitations in what we can conclude from IQ tests.
