Final answer:
The new worker showcases a high level of fluid intelligence through their quick learning of new skills. Fluid intelligence is key for problem-solving and adapting to new situations, which is in line with Cattell-Horn-Carroll theory's classification under broad abilities.
Step-by-step explanation:
The new worker at Consolidated Generic Products who quickly learns a new skill demonstrates a high degree of fluid intelligence. Fluid intelligence is characterized by the ability to see complex relationships and solve problems, which is distinct from crystallized intelligence that involves acquired knowledge and the ability to retrieve it. This type of intelligence is crucial for adapting to new situations and for problem-solving in unfamiliar contexts.
According to the Cattell-Horn-Carroll (CHC) theory, fluid intelligence is a part of the broad abilities, which itself is under the umbrella of general intelligence. In the context of worker productivity and comparative advantage within intra-industry trade, having workers with high fluid intelligence can be beneficial as they may quickly adapt to ongoing changes and learning of specialized products.
