An approach to intelligence which emphasizes domain-specific constraints on knowledge structures is compared to information processing approaches. The evaluation of any cognitive ability as being intelligent crucially depends on prior specification of the formal constraints on the domains of knowledge from which that ability originates.

Such explanations are relevant for theory and policy decisions.…
