What is abstract reasoning?

Abstract reasoning tests appear in IQ-style assessments, graduate recruitment and school entrance exams. The term sounds vague, but it describes a specific kind of thinking.

Rules, not knowledge

Abstract reasoning is the ability to analyze information, detect patterns and relationships, and apply rules to solve problems without relying on prior knowledge of the content. In tests, it usually appears as shapes, symbols or grids where you must work out what changes, what stays the same and what comes next. It's closely related to what psychologists call fluid reasoning.

Abstract reasoning

The capacity to identify underlying rules or relationships in unfamiliar, non-verbal information and use them to predict or complete a pattern.

Common abstract reasoning question types

TypeTaskExample rule
SeriesChoose the next figure in a sequenceA shape rotates 90 degrees each step
MatrixComplete a grid with the missing pieceEach row contains one circle, one square, one triangle
Odd one outFind the figure that breaks the ruleAll but one have an even number of lines
AnalogyA is to B as C is to ?Shape flips horizontally and changes color
GroupingDecide which set a figure belongs toSet A has curved lines, set B straight

A worked example

Imagine a row of three boxes. The first has one dot, the second two dots, the third three dots, and each box's dot moves one corner clockwise. The next box should contain four dots, positioned one corner further round. Two rules operate at once: number increases, position rotates. Many errors happen because people spot the first rule and stop before finding the second.

Abstract vs other reasoning types

AbstractShapes, symbols, gridsMinimal
VerbalWords, sentences, analogiesVocabulary and language
NumericalNumbers, data, calculationsArithmetic skills
SpatialMental rotation, 3D visualizationMinimal, but experience helps

Why "culture-free" is an overstatement

Because abstract tasks reduce reliance on vocabulary or schooling, they have often been treated as measures of reasoning that are less influenced by background. That's only partly true. Familiarity with test formats, time pressure and even cultural exposure to visual puzzles can affect performance. Research on working memory also shows that the number of rules to track strongly affects difficulty.

Abstract reasoning questions

What does an abstract reasoning test measure?+

Your ability to detect patterns and rules in unfamiliar visual information.

Is abstract reasoning the same as IQ?+

No. It's one type of reasoning often included in IQ-style tests.

How can I get better at abstract reasoning tests?+

Practice with varied formats and learn to check for multiple rules at once.

Why do employers use abstract reasoning tests?+

They aim to assess problem-solving with new information, though no single test predicts job success.
