— Occupational IQ research

Philosophers — average IQ & cognitive profile

Published occupational IQ research consistently places philosophers at an average IQ of around 129 — the 97th percentile of the general adult population. This is one of the higher-IQ professions on record.

Why philosophers cluster at this level

Academic philosophers post some of the highest verbal IQ scores of any profession, comparable to physicists on conceptual reasoning. The GRE Verbal scores of philosophy PhD applicants are consistently the highest of any discipline.

What this number really means

An occupational IQ average is a statistical mean, not a hiring criterion. The within-profession standard deviation is typically 10-15 IQ points, which means:

• There are highly successful philosophers scoring well above 144
• And highly successful philosophers scoring well below 114
• Conscientiousness, domain knowledge, emotional regulation, and motivation account for far more variance in actual job performance than the difference between, say, IQ 115 and IQ 125 does

How to interpret your own score against this average

If you're considering this profession or already in it, here's how to read a personal IQ result in context:

• If you score 119–139: you're right in the typical range for philosophers
• If you score above 144: you have meaningful cognitive headroom; you'll likely find the abstract demands of the role easier than peers
• If you score below 114: the profession is still entirely accessible to you — many philosophers succeed at this level — but you may rely more on persistence, structured systems, and specialisation than peers do
