The term that accurately describes common intelligence aligning with the average person's capabilities is crystallized intelligence. Crystallized intelligence refers to the knowledge and skills that individuals acquire through experience and education, encompassing things like vocabulary, general knowledge, and the ability to use learned information in practical situations. This type of intelligence tends to remain stable or even increase with age, as it is built upon a foundation of experiences and learning.

Fluid intelligence, on the other hand, involves the ability to think logically and solve problems in novel situations, independent of acquired knowledge. It peaks in early adulthood and may decline with age. Emotional intelligence relates to the ability to recognize and manage one’s own emotions as well as the emotions of others, and is not directly concerned with general cognitive capabilities. The term basic intelligence is not widely recognized in psychological literature as a formal concept. Thus, the nuanced distinction between crystallized intelligence and the other terms is vital for understanding human cognitive capabilities comprehensively.
