INTJ IQ — what's the average for The Architect?
The average reported IQ for INTJ (The Architect) across published MBTI cognitive studies sits around 127 — placing the typical INTJ in the 96th percentile of the general population.
INTJs consistently rank near the top of cognitive measures, with strong fluid intelligence and pattern recognition. The dominant Ni function correlates with abstract synthesis.
Why INTJs tend to score where they do
MBTI type is not a measurement of intelligence — it's a personality typology rooted in Jung's cognitive function theory. But certain dominant function patterns correlate with cognitive task performance:
- Introversion — tends to favour deep, sustained processing of abstract material
- Intuition (N) — correlates with strong fluid reasoning and pattern recognition on IQ tests, which is part of why NT types consistently score highest
- Thinking (T) — correlates modestly with logical and matrix reasoning task performance
- Judging (J) — has the weakest individual correlation with IQ; matters more for working style than raw ability
The honest caveat
Average IQ by MBTI type is a statistical tendency, not a rule. The standard deviation within any single type is typically 12-15 IQ points — which means there are INTJs scoring well above 145 and INTJs scoring below 90. The type tells you nothing about any individual's actual cognitive ability.
If you want to know YOUR actual IQ rather than the average for your MBTI type, take a properly calibrated test that uses real psychometric scoring (IRT 3PL Bayesian MAP estimation) rather than a quick quiz.
