g was observed as a correlation between test scores.

To be more precise, the existence of g was derived from observing the correlation of test scores.

Moreover, g itself is not the correlation, it is the unobservable underlying factor which we assume to cause the correlation.

It is still a scalar-valued characteristic of a person, not a mechanism.
