IQ is just the wrong way to approach the subject, to be honest. Metacognition plays the biggest role in learning by far and is trainable. But in order to think properly about your thinking, you need the requisite declarative, procedural, and conditional knowledge. Most people, including "intelligent" people, have no clue how learning works.

Even when forced to use effective learning techniques, they rate the effective strategies (as determined by their outcomes) as least effective. We need to start teaching people how learning works to begin with.
