I don't understand what we gain by aggregating multiple types of cognitive abilities under one number. It's like, we wanted to abstract the concept of "being smart" to a single nifty value because that's cool or something, then realized that this is a limited oversimplification, but are trying to hold on to it... because we like the concept??

It works most of the time and is the most replicable and predictive construct in the whole of psychology. Seems good enough to me.
