Innate Intelligence

Innate Intelligence is the most studied of the five factors on the Stanford-Binet, and the one most closely tied to what people mean when they say someone is “sharp.” It is the ability to find a pattern in unfamiliar material, draw an inference from incomplete information, or work out the rule that governs a system you have just been shown.

What Innate Intelligence is

Innate Intelligence, in the Cattell-Horn-Carroll model on which the modern Stanford-Binet is built, is the broad ability behind novel problem-solving. The classic test of Innate Intelligence is a sequence: three shapes, then three more shapes, then a question mark. What comes next? You have not seen this exact sequence before. There is no rote answer. You work it out.

Innate Intelligence differs from knowledge, the second of the five Stanford-Binet factors. Knowledge is what you have already learned and can bring to a new problem. Innate Intelligence is what you do when knowledge runs out.

How it is tested on the Stanford-Binet

On the SB5 (the current edition of the Stanford-Binet, published in 2003), Innate Intelligence is measured both verbally and nonverbally. Verbal items include analogies (X is to Y as Z is to ?) and absurdities (find what is wrong with this short statement). Nonverbal items include object-series matrices and “early reasoning” sequences, which work without any language at all.

The verbal-and-nonverbal split is one of the SB5’s important corrections. Earlier editions of the test were heavy on language, which meant English-as-a-second-language test-takers and people with language-specific learning differences scored artificially low. The 2003 redesign fixed it. Our online assessment uses the same balanced design.

What a strong fluid-reasoning score predicts

Higher Innate Intelligence is associated with faster acquisition of new skills, better performance in unstructured environments, and a particular kind of comfort with abstraction. It is the single best predictor of how someone will do at a job they have never done before. It is a poor predictor of how someone will do at a job they already do well.

Innate Intelligence peaks early — around age 25 — and slowly declines from there. This is not a sentence. People stay productive into their eighties on the strength of accumulated knowledge, which keeps growing. The Cattell-Horn-Carroll literature calls the trade-off investment theory: Innate Intelligence is invested over time into knowledge.

Can Innate Intelligence be trained?

Modestly, and not in the ways popular brain-training apps promise. Decades of careful studies on “brain games” find that practice on a specific task improves performance on that task, but transfer to general Innate Intelligence is small and inconsistent. What does help, in the longer term: sustained engagement in cognitively demanding work, regular sleep, aerobic exercise, and the kind of unfamiliar reading that forces you to figure out a new domain. None of this gives you twenty IQ points. All of it shifts the dial a little, over years.
