INFP IQ — what's the average for The Mediator?
The average reported IQ for INFP (The Mediator) across published MBTI cognitive studies sits around 117 — placing the typical INFP in the 87th percentile of the general population.
INFPs score above average overall, with particular strength in verbal and abstract domains.
Why INFPs 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
- Feeling (F) — correlates with verbal-conceptual reasoning strength
- Perceiving (P) — 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 INFPs scoring well above 145 and INFPs 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.
