We welcome Blair's argument that the relationship between fluid cognition and other aspects of intelligence should be an important focus of research, but are less convinced by his arguments that fluid intelligence is dissociable from general intelligence. This is due to confusions between (a) crystallized skills and g, and (b) universal and differential constructs.
1. We prefer to use the “Gf” abbreviation used by Cattell and Horn to signify fluid intelligence; Blair’s use of “gF” is unusual.
