Which type of intelligence involves knowledge gained through life experiences?

The correct answer is crystallized intelligence, which refers to the accumulation of knowledge, facts, and skills that are acquired throughout an individual's life. This type of intelligence is heavily influenced by education, cultural factors, and personal experiences. As people engage in various life experiences—whether through formal education, practical experiences in the workplace, or social interactions—they develop a repository of knowledge that can be applied to solve problems and navigate daily challenges.

Crystallized intelligence typically increases with age, reflecting the long-term memory of information and skills that have been learned over time. It enables individuals to utilize their past experiences and learning to make informed decisions and understand complex ideas, making it a crucial component of cognitive functioning.

The other types of intelligence mentioned are distinct in their characteristics: fluid intelligence refers to the ability to think logically and solve problems in novel situations, independently of acquired knowledge; social intelligence encompasses an understanding of interpersonal dynamics and social situations; and practical intelligence involves the ability to adapt to everyday life and solve practical problems. Each of these has its unique focus and does not primarily revolve around knowledge gained through life experiences in the same way crystallized intelligence does.
