A general factor connects all other items. If an item represents an ability then the general factor is what raises all of them together. The higher the general factor the more consistent all abilities raise together around it. The brain is a network so (g) would be the central hub or core ring. This hub would be the main control unit of the attractor landscape, shifting how the network pays attention to the different subnetworks. The ability to shift between the different subnetworks allows the development of abilities. (g) is the coordination of subnetworks by a core network.
The coordination of the brain as a network gives it the general ability for manipulation of many types of variables mentally. And keep different sets of relationships in mind.
