Verbal reasoning works with words; non verbal reasoning works with shapes, patterns, and diagrams that carry no language. Both measure reasoning ability, but non verbal tests were designed to reduce the influence of language and culture. They are better described as culture reduced than culture free, and employers often use both.
If you sit a reasoning assessment, you may meet a section with no words in it at all, only grids of shapes to complete. This can happen whether you are applying for an entry level job or a senior leadership role, since these tests are used across the board. Candidates who have prepared for verbal reasoning sometimes find this disorienting. It helps to understand that verbal and non verbal reasoning are two windows onto the same underlying ability, built to work in different ways and for different reasons. This article explains what each one tests, how they differ, why employers use both, and the honest answer to the question people most want settled: whether non verbal tests are really fairer.
What is the difference between verbal and non verbal reasoning?
The difference is the material you reason with. Verbal reasoning gives you written information and asks what follows from it, so it draws on both your store of language and your reasoning. Non verbal reasoning gives you shapes, figures, and patterns, and asks you to work out the rule that governs them. It draws mainly on your reasoning with novel material, and little on what you have learned.
Put another way, verbal reasoning leans on accumulated verbal knowledge as well as reasoning ability. Non verbal reasoning is closer to a direct measure of the capacity to reason with something you have never seen before. That is why the two can give a fuller picture together than either alone. They share a large common core, the general reasoning ability that runs through both, but each adds its own information.
What does a non verbal reasoning test measure?
A non verbal reasoning test measures your ability to identify rules in unfamiliar patterns and apply them. Psychologists treat this as a fairly direct measure of fluid intelligence, the capacity to reason with novel problems. The most familiar form is the matrix, a grid of figures with one cell missing that you must complete.
A detailed study of how people solve the best known matrix test, the Raven matrices, found that strong performers do two things well. They work out the abstract rules that govern how the figures change across the grid, and they hold and manage several such rules at once without losing track. The hardest items simply stack more rules on top of each other. This is why the test works as a measure of reasoning: it taxes the system that induces and juggles abstract relations, with no vocabulary or general knowledge to fall back on.
Is non verbal reasoning a measure of fluid intelligence?
Largely, yes. Non verbal reasoning tests, and matrix tests in particular, are among the closest practical measures of fluid intelligence, the ability to reason with novel material rather than to recall learned knowledge. That is precisely why they use shapes and patterns rather than words, since words would bring in the learned, crystallized knowledge that fluid intelligence is meant to set aside. No single test is a pure measure of anything, but matrix tests come unusually close to isolating reasoning with novelty.
Why do employers use non verbal reasoning tests?
Employers use non verbal reasoning tests for two main reasons. First, they measure reasoning with novel problems directly, which is valuable for roles that involve unfamiliar situations rather than routine knowledge. Second, because the items carry no language, they can be used with candidates from different language backgrounds and education systems on a more even footing than a verbal test allows.
This second reason is why non verbal tests are popular in international hiring at every level, from graduate intakes to senior appointments that draw applicants from many countries. A verbal reasoning test inevitably advantages those who are most fluent in the language of the test. A non verbal test removes that particular advantage, at least in principle, which is its main attraction. Whether it removes it fully is a separate question, and an important one.
Are non verbal reasoning tests culture free?
No. Non verbal reasoning tests are better described as culture reduced than culture free. Removing words lowers the influence of language and learned knowledge, but it does not remove the influence of schooling, familiarity with abstract diagrams, and experience with test formats.
The evidence is clear on this. A major review of the Raven matrices across cultures documented that scores vary considerably between countries and groups. They have also risen substantially over the twentieth century, which a purely culture free measure of a fixed ability would not do. A later analysis of variation across time and place confirmed that performance on these tests depends on environmental and educational factors, not on reasoning alone. So while a non verbal test reduces the language advantage, it does not erase the effects of a person’s background. Calling it culture reduced is honest. Calling it culture free is not.
Are non verbal reasoning tests fairer than verbal ones?
They are fairer in one specific respect and not a general cure. By removing language, a non verbal test lowers the disadvantage faced by candidates who are not first language speakers of the test language. That is a real and useful gain. But because schooling and familiarity with abstract material still shape scores, non verbal tests can still produce differences between groups. They are a sensible choice where language would otherwise be a barrier, but they should not be treated as a complete answer to fairness in testing.
Is non verbal reasoning completely separate from verbal reasoning?
No. The two are distinct in what they present to you. But they are not sealed off from each other, either in the mind of the test taker or in what they measure. They share the general reasoning ability that underlies both, and people often borrow strategies from one to solve the other.
A revealing experiment on matrices showed this directly. When people were prevented from talking themselves through the items, their performance dropped on a particular subset of problems. Those supposedly non verbal items were being solved with verbal, step by step reasoning. The finding is a useful corrective. A non verbal test is not a test of some wholly separate, wordless intelligence. It is another route to the same general reasoning ability, and capable people recruit whatever strategy, verbal or visual, the problem rewards.
Key takeaways
1. Verbal reasoning works with written information and draws on both verbal knowledge and reasoning; non verbal reasoning works with patterns and draws mainly on reasoning with novel material.
2. Non verbal reasoning tests, especially matrix tests, are among the closest practical measures of fluid intelligence, the ability to reason with novelty.
3. Strong matrix performance comes from inducing the abstract rules in a pattern and holding several of them in mind at once.
4. Employers use non verbal tests to measure reasoning directly and to assess candidates across language backgrounds on a more even footing.
5. Non verbal tests are culture reduced, not culture free. Scores still vary with schooling, background, and have risen over time.
6. They are fairer than verbal tests in removing the language advantage, but they are not a complete answer to fairness, because background still matters.
7. Verbal and non verbal reasoning are not sealed off from each other. They share a general reasoning ability, and people use verbal strategies on some non verbal items.
What this means for you
If your assessment includes a non verbal section, do not treat it as a foreign object. It is testing the same reasoning you use everywhere, just stripped of words. Look for what changes across each row and column of a pattern. Name the rule to yourself even though the item has no words, and build up from the simplest rule to the most complex. The same patient, rule by rule approach that serves you in verbal logic serves you here.
Take some comfort from the fact that the two are linked. If you reason well with words, you have a reasonable head start on patterns, because both rest on the same underlying ability. And keep the result in proportion. Whether verbal or non verbal, a reasoning score is one of the qualities an employer weighs, not a full measure of what you bring to a role.
