Might I add that there is an historical element to the value and/or opinions of IQ scores as measures of academic potential.
A few developed countries had accepted it as a predictor of schooling performance around the 50s, but several problems emerged. Some racial groups (e.g. blacks in USA) were consistently underperforming, suggesting either that they had innately lower intelligence (the initial view, used to justify prejudices towards such populations) or that the IQ tests were racially biased (later found to be a sufficient explanation, despite claims that IQ tests measure general intelligence with minimal bias).
Although IQ tests have since been revised to be more culture-neutral, the outcome of those initial problems was IQ testing was scrapped as a method for assessing academic potential, and replaced with more specific evaluators, as used today.
Some of the opinions about the value of IQ scores are thus based in part on its known practical limitations from the past. Nonetheless, some individuals and groups of persons (e.g. MENSA) do focus on the implications of IQ measures, and IQ research.
