Astronauts show an average IQ of approximately 132, placing the median practitioner at the 98th percentile of the general adult population — the top 2%. This estimate is derived from occupational sampling studies, GRE/SAT score conversions for entry-level practitioners, and meta-analyses of cognitive ability data by profession.

Why Astronauts cluster at this IQ level

The profession selects for, and then trains, the cognitive abilities required to do the work. Astronauts show particular strength in spatial, executive, logical — the cognitive axes that most predict performance in this field. These traits cluster because the work itself demands them and because entry filters (degrees, exams, certifications, interviews) screen for them.

Within the science field, Astronauts sit relatively high compared to peers. The standard deviation within the occupation is typically 10-15 IQ points, meaning roughly two-thirds of working Astronauts fall in the IQ 117-147 band.

What this average does NOT mean

An occupational IQ average is a statistical mean, not a hiring criterion. 132-level cognition is the typical Astronaut, not the minimum. Plenty of working Astronauts score below 117, succeeding through experience, conscientiousness, deep domain knowledge, and motivation — none of which IQ tests measure.

The average also describes the people who entered and stayed in the profession. It does not predict whether you specifically could succeed as a astronaut. Personal interest, work ethic, and circumstance matter at least as much.

How to read your own IQ against the Astronaut average

Frequently asked

What is the average IQ of a astronaut?

The estimated average IQ for Astronauts is 132, based on occupational sampling and GRE-derived data. This corresponds to roughly the 98th percentile.

Do you need a high IQ to be a astronaut?

There is no formal IQ requirement. The 132 average reflects who tends to enter and stay in the profession, not a minimum threshold. Successful Astronauts exist well above and below this number.

What's the highest-IQ profession?

Physicists, mathematicians, and astronomers cluster around 131-132 average IQ. The top tier of professions are within 3-4 IQ points of each other.
