“Performance on image rotation tasks is known to predict success in fields such as airplane piloting, engineering, physical sciences, and fine arts better than does general intelligence, and especially verbal ability. What has perhaps not been recognized is that inclusion of verbal ability in assessments used to recruit individuals to those fields may actually act to impair efforts to select those with the talents most relevant to the jobs in question.”
"... we have presented evidence supporting the idealized notion of general intelligence as a general-purpose mechanism that accesses a toolbox made up of components that vary from individual to individual. Though everyone clearly has most if not all of the same tools, individuals appear to differ not only in the skill with which they use their tools, but also in the specific tools they habitually use. For some of the more specific tools, it would appear that using one tool means failing to use another.
