Abstract Reasoning

What are abstract reasoning tests and why are they used?

Abstract reasoning tests (also known as inductive reasoning or Diagrammatic Reasoning tests) are widely used within selection processes to assess a candidate's general intellect and ability to work out new concepts and abstract ideas, rather than testing their prior knowledge. They are closely correlated with IQ tests, and rely upon the candidate's ability to see the underlying logic in a pattern of symbols or shapes (instead of relying on words or numbers).

This type of test is useful to employers because the ability to answer abstract reasoning questions is independent of educational experience and cultural background, and can be used to provide an objective indication of intellectual potential.They are particularly useful for jobs where problem-solving and initiative are important, or where candidates will need to deal with complex data, or perform non-routine tasks where initiative is required.

That said, abstract reasoning questions may be used by any employer as an assessment for any position, as they are seen to be a good measure of general intelligence, and test your ability to perceive relationships and work out co-relationships, without any prior knowledge of language or mathematics.

To successfully complete abstract reasoning tests, you need to be able to think creatively and use lateral thinking (also known as fluid intelligence) to solve novel problems. You also need to see the relationships between shapes and figures, identify rules and similarities, and quickly apply these to identify the answer.

Success in abstract reasoning tests is about spotting the patterns.

What to expect from your abstract reasoning test

Abstract reasoning tests are designed to be challenging, in order to differentiate between candidates and to identify the maximum performance they are capable of. They usually have tight time scales, and questions that rapidly increase in difficulty. This means that you will need to identify more rules to solve the problems, and that the complexity of these rules is likely to increase.

While there are many permutations of question types and formats, there are some general concepts which are common, and it can be useful to familiarise yourself with these.

Common question types in abstract reasoning tests

Question 1: Identify the missing square

Abstract reasoning tests

This type of question requires you to look at the patterns in the squares and understand their relationship to one another, so as to identify the missing square.

There are three rules to spot in this question. Firstly, there is a relative positional rule: the position of the black square corresponds to the position its square holds within the diagram. Secondly, there is a movement rule, in that the circle moves around the boxes in a clockwise position. Finally, the arrows in the first and third columns are reflections of one another. The correct answer is therefore C.

Question 2: Complete the sequence

Abstract reasoning tests

This requires you to identify and understand the pattern behind the order in which the dominos are presented. There are two patterns here. The first, third and fifth (and therefore seventh) dominos have the rule that the number of the top is six and the number on the bottom is increasing by one each time. The second pattern includes the second, fourth and sixth dominos, and has the rule that the number on the bottom is four and the number at the top is decreasing by one each time. The correct answer is therefore C.

Question 3: Identify the odd one out

Abstract reasoning tests

This type of question requires you to look at some data, identify the pattern or rules, and then spot which square does not meet those rules. Watch out for relative position, number of items, relationship between items, colour, shape, and orientation of shapes: there are many different variations on these rules and there may be some extraneous data in there that complicates the rules.

For example, in this question some of the square have three items in and some have four – you need to work out whether or not that is important. In this particular case, there are two rules. The first is that the largest shape must be grey, and the second is that the bottom shape must be black. The odd one out is therefore C, as the bottom shape is stripy and not black.

Question 4: 1 is to 2, as 3 is to 4

Abstract reasoning tests

This type of question is all about relationships between data: being able to recognise what links two boxes together and then apply this rule to a new shape to solve the problem.

There are two rules here. First, the shape in box 2 has one more side that the shape in box 1. As the shape in box 3 has six sides, the correct shape for box 4 must have seven sides. The second rule is around the arrow and the rule is that for shapes with an even number of sides, the arrow points up. For shapes with an odd number of sides the arrow points down. The correct answer is therefore A.

How to prepare for your abstract reasoning test

Abstract reasoning ability is closely correlated with general intelligence. However, familiarity with the types of questions you are likely to encounter and some strategies for solving the questions will certainly help you perform at your best.

  1. Many people find they enjoy the mental challenge of solving abstract reasoning tests! There is a range of puzzle books and apps available that you can use to practise with. Similarly, many test publishers provide practice tests that you can access, such as AssessmentDay and JobTestPrep; this is certainly worth doing.

  2. It can be useful to develop a mental checklist of strategies to solve abstract reasoning questions, such as a list of different rules that govern data like size, shape, number etc. This gives you a starting point to think about questions and can help you work methodically in the test.

  3. Look at one rule at a time. There may be extraneous data within the question, which is designed to confuse you. Looking at only one aspect of the question at a time can help you work out what is important and what isn’t.

  4. Manage your time. Sometimes you will come up against a question where you just cannot see the answer. On these occasions, don’t spend too much time on it, move on and if you have time at the end, go back and check it.

  5. If you’re struggling to find a pattern, sometimes there are clues in the answers. Look for any patterns or themes in the possible answers; that might help you spot what is important within the question. For example, if you have a sequence of shapes and all of the answers are squares or triangles, you know that the next shape in the sequence must be either a square or a triangle and that can help you work out why.
