Test Your IQ, Free 20-Question Intelligence Assessment

This IQ Test measures your cognitive abilities across four key dimensions: pattern recognition, verbal reasoning, numerical ability, and logical thinking. These are the same dimensions tested in clinical IQ assessments like the Wechsler Adult Intelligence Scale (WAIS), condensed into 20 quick questions. The modern idea of an intelligence quotient traces back to Alfred Binet's 1905 work and was put on the 100-point, 15-standard-deviation scale by David Wechsler, the scaling this test mirrors.

Psychologists draw a useful line between fluid intelligence, your ability to reason, spot patterns, and solve novel problems without prior knowledge, and crystallized intelligence, the accumulated facts, vocabulary, and know-how you have built over a lifetime. The pattern, numerical, and logic items lean on fluid reasoning, while the verbal items tap crystallized knowledge, so the breakdown shows you which side of your cognition is doing the heavy lifting.

While not a replacement for a clinically administered IQ test, this assessment gives you a reliable directional indicator of your cognitive strengths and areas for growth. The questions range from classic number sequences and analogies to tricky logic puzzles and spatial reasoning, and the four-domain breakdown tells you where you are sharpest and where a little practice would move the needle most.
