Why are IQ tests controversial?

Answer 1

IQ tests contain cultural bias; people in certain cultures have certain kinds of knowledge that people in other cultures don't have, and that knowledge is then used in IQ tests as evidence of superior intelligence, which then becomes a way to make some ethnic groups seem to be smarter than others. Aside from that problem, we do not really know that any IQ test accurately measures intelligence; the only thing we can say with certainty about IQ tests is that they measure the ability to do IQ tests.

Answer 2

IQ tests are controversial because they are seen as limited measures of intelligence that may not fully capture an individual's abilities or potential. Critics argue they may be biased against certain groups based on cultural or socio-economic factors, and that they can perpetuate stereotypes. Additionally, some raise ethical concerns around the implications of labeling individuals based on a single test score.
