IQ tests are weakly predictive of academic success, especially on the high end (1SD+). In general, it only predicts 8-25% of variance, even when looking in both directions. That's pretty bad, an average exam does a far better job.

Additionally, the IQ of second generation Asian immigrants will revert to the mean. Not only that, but the advtange decreases rapidly as they age, while the academic advantage grows. And the advantage to begin with is very small - average Asian IQ is only about 2.5 points higher than for Whites, even looking at all generations together.

Given the impact of early childhood environment on IQ, and the huge disparity in academic effort across cultures, esp. those that constitute Asian immigrants, it's pretty clear that the idea that the disparity in Asian achievement cannot be explained by an inherited intelligence advantage. All the data is much more consistent with a culture that just drives students to study far harder.

This does make the argument that affirmative action is harmful even stronger, actually. There is no need to fall back to terrible science to do it. The idea that IQ isn't terribly useful is because it isn't terribly useful, except in very rare cases for diagnosis. The current scientific consensus is consistent with an even stronger argument that AA unfairly discriminates against Asian students.
