The best recent estimate of the average IQ of lawyers is about 114, from 94 solicitors in the UK Understanding Society survey (Wolfram, 2023) — roughly the 83rd percentile. The spread is wide: many lawyers score around 100 and some well above 130.
What the data say about lawyers’ IQ
The most recent large dataset with occupation-level cognitive scores is the UK Understanding Society survey analysed by Wolfram (2023). In the tabulated results, solicitors (N = 94) had an estimated mean of 114.2, one of the highest values among the professions listed and very close to physical scientists (114.4) and medical practitioners (112.7). Wolfram’s paper lists lawyers among the groups near the top of the occupational ranking.
The data cover solicitors in England, Scotland and Wales. Separate figures for barristers, judges or US attorneys were not part of the subset we could verify, and we do not extrapolate. Lawyers are a broad group: corporate transactional lawyers, legal aid solicitors, prosecutors and in-house counsel do very different work.
Lawyer IQ range
Assuming the typical within-occupation spread (SD about 13), around two-thirds of solicitors would score between about 101 and 127. Roughly 14% would score below 100, and roughly 11% at 130 or above:
| IQ range | Solicitors (model) | General population |
|---|---|---|
| below 90 | ~3% | 25% |
| 90–99 | ~11% | 25% |
| 100–109 | ~24% | 25% |
| 110–119 | ~30% | 16% |
| 120–129 | ~22% | 7% |
| 130 or above | ~11% | 2% |
Model: normal distribution around the estimated mean with SD 13, the average within-occupation spread implied by Wolfram (2023), where roughly three-quarters of IQ variance lay within rather than between occupations. Real distributions can be skewed.
Is the LSAT an IQ test?
No. Law school admission tests such as the LSAT (US/Canada) or the LNAT (UK) assess reading comprehension and logical reasoning, which overlap with general cognitive ability, but they are designed and normed for law school applicants, not the general population. Converting LSAT scores into IQ points — a common internet exercise — has no published, validated basis, so we do not offer one.
What makes a successful lawyer besides IQ?
Legal work rewards verbal precision, careful reading, and the ability to hold many rules and facts in mind at once — all things that correlate with general ability. But client work, negotiation, advocacy, judgement under uncertainty, ethics and sheer persistence matter enormously. Meta-analyses of job performance across occupations find that general mental ability is a useful but partial predictor (about .51 in Schmidt & Hunter, 1998; about .31 after Sackett et al., 2022). Structured judgement, experience and conscientiousness carry much of the rest.
For people considering law, a more useful question than “is my IQ high enough?” is “do I enjoy close reading, arguing from rules and detail-heavy work?” The occupational overlap shown above means interest and work habits are far better guides than a test score.
How to read these numbers
Every number on this page comes with three caveats. First, the UK estimates are based on a short survey battery — word recall, number series, everyday numeric problems, serial subtraction and verbal fluency — rather than a full clinical IQ test, so they are less precise for individuals and tend to compress group differences. Second, they describe people working in an occupation at one time (2011–2013), not what the job requires. Third, they are averages: Hauser’s analysis of the Wisconsin Longitudinal Study found that the correlation between occupation and measured ability was only moderate (about .39–.44), and that the spread of ability was almost as wide in high-status occupations as in others.

Frequently asked questions
What is the average IQ of lawyers?
Recent UK data (Wolfram, 2023) estimate about 114 for solicitors (N = 94) on the standard IQ scale, among the highest of the occupations listed.
Do lawyers have a higher IQ than doctors?
In the UK estimates the two are very close (solicitors about 114, medical practitioners about 113), well within the uncertainty of the figures.
What IQ do you need to be a lawyer?
There is no IQ requirement. Admission depends on degrees, admission tests such as the LSAT or LNAT, and professional exams. Many successful lawyers score in the 100–125 range.
Can you convert an LSAT score to IQ?
Not reliably. There is no validated conversion between LSAT scores and IQ, because the tests are normed on different populations for different purposes.
