I agree that its very plausible that grades affect self perception. However, I have low confidence that it would be more predictive than IQ.
Same could be said for conscientiousness, but thus far it seems like the behavioral testing and the reports from grade-naive “homeroom” teachers seem to increase the correlation rather than decrease it compared to self-report alone.
I don’t have strong opinions on the subject, but I wouldn’t necessarily expect uniform results across the IQ spectrum. It might well be that different things are more predictive at different ends of the IQ curve.
In particular with respect to IQ and conscientiousness, it seems to me that at high IQ levels the “necessary-for-A+” IQ tops out and conscientiousness starts to dominate, while it’s the reverse with low IQ—if you’re just not smart enough, conscientiousness won’t help much.

I low-confidence-agree with you. That seems gut-level correct, and fig 1 supports this notion but I don’t know the extent that trend should be trusted and there are other possibilities.
If I had to guess I’d rephrase it as ” both have diminishing returns, but the diminishing returns on IQ are both more dramatic than those on conscientiousness.”
actually, looking at figure 1 it doesn’t look like self discipline has diminishing returns at all, whereas it looks like IQ does. Just eyeballing, the “IQ test ceiling” for GPA is the 3rd quintile of this population’s OLSAT7 lv G scorers whereas Self Discipline doesn’t even hit a ceiling. But conclusions via eyeballing would be criminally non-rigorous :)
