I'm not exactly sure what IQ is, but if it's something like natural talent, then sure, people talented at math will learn it faster. I was merely making the point, drunkenly, that students with a rigorous grade school math education, such as those in China, will handle advanced material much better than those who don't study geometry until high school, like in the US. This might lead to the perception that the better prepared students are in some ways more talented at math, even though the knowledge is often literally beaten into students.
I think I butted into this thread cuz I was curious about the mismatch study. Though my personal experience is narrow, I've observed mostly two kinds of students who get weeded out in CEE (not sure if this applies to mechanical as well, obviously not to EE/CSE/BME, anything not dependent on Newtonian physics). 1, Those who couldn't draw free body diagrams in statics, and 2. couldn't apply or derive deflection/moment/load functions in mechanics of materials. The 1. students have no future in any physics related subject. There are many people who can't picture how forces interact with objects, I don't think this is indicative of general intelligence, let alone dependent on race. The 2. students are bad at math, I can't see how this isn't heavily dependent on pre-college education given how basic the subject is, compared to something like calc 3, which every engineering major across the country have to take.
