Simply put, a logical reasoning test measures an individual's ability to analyze information, problem-solve, draw meaningful conclusions from the evidence presented, as well as one’s ability to reason in a coherent and logical manner. To achieve this objective these tests typically present an applicant with a series of written passages and/or non-verbal content such as pictures and diagrams.
Types of logical reasoning assessments include Inductive and Deductive Reasoning tests. Descriptions of both types of reasoning, how they are often presented to candidates in a testing environment, as well as frequently asked questions are provided below.
Deductive Reasoning
Deductive reasoning begins with one or more general statements (premises) or hypotheses and examines a situation to reach a conclusion that is perceived to be logical. For example, consider the statements:
- All cars are fast.
- Mary has a car.
- Therefore, Mary’s car is fast.
Deductive reasoning tests are usually presented as a series of short paragraphs where a candidate is asked to arrive at the most logical conclusion based on the premises. The most logical conclusion will usually be presented among other less logical conclusions in the form of a multiple-choice response-type, though sometimes conclusions could be presented in true-false format.
Inductive Reasoning
Inductive reasoning uses specific information (premises) to arrive at broader, generalised conclusions. However, while the conclusion of a deductive argument is expected to be absolutely certain, the conclusion of an inductive argument is a probable one, based on the evidence provided. An inductive argument’s conclusion can therefore never be 100% guaranteed, and as such could be seen as a ‘best guess’. For example, consider the statements:
- Mary and Paul are left-handed and use left-handed scissors.
- Antonio is also left-handed.
- Therefore Antonio also uses left-handed scissors.
Inductive reasoning tests typically require candidates to make general inferences (probable conclusions) based on shapes, patterns, sequences, and diagrams. Based on this information, test takers are asked to quickly ascertain relationships and rules, and then apply these to find the most logical (probable) answer from a set of multiple-choice options.
