Psychometric intelligence research and recent cognitive studies consistently confirm that general fluid intelligence is a distinct and measurable component of human cognitive ability.

The analysis

The retrieved literature strongly supports the claim. Paper [0] highlights the enduring validity of hierarchical psychometric models of human intelligence, such as Carroll's three-stratum theory and CHC theory. Paper [1] isolates fluid intelligence as a distinct driver of strategic analytical thinking. Both sources reinforce the concept of fluid intelligence as a distinct cognitive component.
