What is IQ and what does an intelligence test measure?
IQ (Intelligence Quotient) measures cognitive processing speed, problem-solving, and pattern recognition — not knowledge, wisdom, or life success. The average IQ is 100 with a standard deviation of 15.
Modern IQ tests measure 5 related abilities: Verbal Reasoning, Numerical Reasoning, Logical Reasoning, Spatial Reasoning, and Working Memory.
What IQ does NOT measure: wisdom, creativity, emotional intelligence, motivation, or life success (though IQ correlates with career success at r ≈ 0.5).
