No study separates general practitioners from other doctors, so this is the best figure for GPs.

On the standard scale, where 100 is the average, 120 is higher than about 91% of people. See what an IQ of 120 means, or check any score with the IQ percentile calculator or the IQ chart.

Your score next to doctors

Below the typical range for doctors in the studies. Plenty of people work in roles above their measured IQ; training and experience matter.

In the general population, 110 is higher than about 75% of people. Shaded band: middle 50% of doctors (112 to 127).

What the studies show

Physicians had the highest median of any job group in the Wisconsin Longitudinal Study: about 120, measured in high school decades before. A tenth scored below 106 and a tenth at or above 133, where the chart tops out.

No published source splits general practitioners from specialists. Medical school selection is similar for both, so the physician figure is the most honest answer for a GP.

The Wisconsin study is one US state, one generation born around 1939, and almost entirely white. Its IQ scale is anchored to Wisconsin high-school juniors in 1951, not to a national norm. Treat every figure as an estimate within a few points.

Making the career sustainable

People fail in high-load jobs for two reasons: insufficient systems or unmanaged stress. Both can be trained, if you treat them like skills.

General reasoning affects how fast people learn a role, but it is not a gate. Qualifications, practice, domain knowledge, tools, teamwork and job design all change performance.

Average IQ of a general practitioner: questions people ask

What is the average IQ of a doctor?

About 120, the median for physicians in the Wisconsin Longitudinal Study. The middle half scored between 112 and 127.

Do GPs have a lower IQ than surgeons?

There is no data that separates them. Both pass through the same medical school selection, and no published study compares their IQ.

What IQ do you need to be a doctor?

There is no IQ requirement. Medical schools select on grades and admissions tests such as the UCAT or MCAT. A tenth of physicians in the Wisconsin study scored below 106.

Is being a general practitioner stressful?

Stress demand is rated 6/10 with burnout risk Moderate. If you don’t build recovery (sleep, boundaries, exercise), stress compounds.

What personality traits help a general practitioner?

Roles with high structure demand (3/10) reward conscientiousness; roles with high social demand (9/10) reward social energy and emotional regulation.

Can I succeed as a general practitioner if I’m below the “recommended” IQ?

Yes. There is no valid IQ cutoff for this occupation. Qualifications, deliberate practice, experience, support and role specialization are more useful career decisions than comparing yourself with an estimated benchmark.
