Effort doesn't necessarily translate to success because you can try tirelessly at a task, but continue to fail if you aren't actually training yourself properly (Most people have no idea that you need to "Learn how to learn," and it's not an idea heavily emphasized in US schools honestly), or lack the educational background to make the absorption of the material more effective. This effect compounds over time to make you lag in your academics. The analogy I give my students is that if you're trying to chop down a tree, you can smack it with a baseball bat for as long as you like, you're not going to advance as quickly as someone who's using an axe. The analogy is meant to demonstrate that you need the proper tools (Interest, study skills, background knowledge, and time management) to advance yourself at a decent pace in a difficult subject.
Basically all of the students who don't do well in my class either don't care about the subject, have bad student skills, or had/have an upbringing that clearly didn't foster an emphasis on education. You just don't want to accept responsibility. You're terrified of the idea of being at fault for your own failures, so you explain it away with IQ scores because it removes your own accountability- Either to make yourself feel better, or to make other people feel worse because you have the same emotional and social maturity as an elementary school bully on a playground. It's much easier to just use a number you pulled out of an online quiz than to actually understand the complications of succeeding academically. Ironically, it's the thing stupid people do.
Literally nobody in my departments during undergrad (Astronomy/Physics double major) ever talked about IQ scores, because well-educated people don't give a shit about it.
I'm not saying some marginal aspects of intelligence aren't genetic in nature, but projecting tirelessly about IQ is just a coping mechanism.
