When it comes to intelligence classifications, your brain might automatically jump to a black-and-white picture of society: those with the brains to succeed, and those without (otherwise known as ‘entity theorists). Others may think of left-brain vs. right-brain, the 7 types of intelligences, or simply have a broader understanding that each brain has different strengths (otherwise known as incremental theorists). Studies show that the more rigid entity theorists tend to be discouraged by negative feedback and challenging learning opportunities, while incremental theorists rebound better from failures because they recognize that intelligence is malleable.
There is, in addition, yet another aspect to intelligence that fits into both of these modes of thinking: fluid intelligence vs. crystallized intelligence. The first, fluid intelligence is what most of us were taught in schools. Fluid intelligence involves comprehension, reasoning and problem solving. Crystallized intelligence, however, involves recalling stored knowledge and past experiences. In short: knowledge vs. wisdom. The bad news? Fluid intelligence peaks when we are in our 30s, and goes into decline after that. Our mental speed and dexterity are no longer what they once were. The good news? Crystallized intelligence begins to rise in proportion to the decline in fluid intelligence. We are able to rely on our stored fluid intelligence to notice patterns and connect otherwise unrelated experiences or events based on shared information.
