This twins study shows that general intelligence and academic achievement are affected by many different "aptitudes", not just "smart." Taken together with the Nature commentary, suggests that intelligence is just a part, maybe even a small part, of achievement.
If only this could seep into the general consciousness of the masses, then we might not have so many students think they cannot do something because they are not "smart enough."
