False
Why
False. The correlations were the basis for a second-order factor, and the debate continued rather than resolving. Thurstone maintained the primary abilities were the useful level of description. Modern hierarchical models like Carroll's three-stratum theory keep both, with g at the top and specific abilities beneath.
