Current thinking suggests that fluid intelligence, which is the ability to reason and solve novel problems, decreases across the life span, while crystallized intelligence, which is knowledge and skills gained through experience and education, remains stable or may even increase. This is likely due to the fact that fluid intelligence is more reliant on processing speed and working memory, which tend to decline with age, while crystallized intelligence is based on accumulated knowledge and expertise, which can continue to grow with experience.
