Fluid intelligence tends to decrease with age, while crystallized intelligence, which benefits from accumulated knowledge and experience, can increase or remain stable over time. The statement that fluid intelligence has increased more than crystallized intelligence reflects the observation that younger generations often perform better on tests of fluid intelligence, possibly due to better health, education, and more stimulating environments, a phenomenon known as the Flynn effect. However, crystallized intelligence, being dependent on accumulated knowledge, also shows generational improvements but is more directly tied to educational and cultural opportunities, which can vary widely.
