Fluid & crystallized intelligence

It is commonly observed that as one ages, one develops a desire to share knowledge and help others acquire it, thereby making a positive impact on individuals and society as a whole. This urge is often driven by the enhanced crystallized intelligence that develops over time, which is optimized for accumulating knowledge and experiences and compressing them into simplified mental models that can be easily taught to others. Crystallized intelligence is in contrast to fluid intelligence, which is rooted in intuition and inexperience and is the capacity for creative and abstract reasoning, as seen in design thinking. The theory of crystallized and fluid intelligence was first proposed by Cattell in 1963.

Fluid intelligence tends to decline with age, while crystallized intelligence increases as you accumulate experiences and grow older. This decline in fluid intelligence may be due to the gradual cognitive decline associated with aging, or because it is used less frequently as one gets older, thus losing its effectiveness over time.

With this understanding, you can examine the role of fluid and crystallized intelligence in your daily life, and how adept you are at shifting between these two states of consciousness. Each intelligence type has its own role depending on the context. When faced with a creative problem in your business or personal life, tapping into your fluid intelligence may be most beneficial, especially in the early stages where creativity is crucial. On the other hand, when advising your child on navigating the uncertainties of a romantic relationship or work situation, drawing upon the resources and knowledge accumulated throughout your life becomes important.

Practicing and balancing both types of intelligence is valuable. Neglecting either type can disrupt the equilibrium between chaos and order, yin and yang, within yourself.
