What is Deductive Reasoning?Deductive reasoning tests measure the ability to draw logical conclusions from a set of premises that are known to be true. In deductive reasoning tests, questions may require you to complete scenarios or to identify the strengths and weaknesses of a given argument.
Deductive Reasoning vs. Inductive ReasoningPeople often confuse the definitions of inductive and abductive reasoning with deductive reasoning. These three types of reasoning are all part of logical reasoning. As explained above, deductive reasoning or deduction is a method in which one applies a certain rule given by a statement or argument to reach specific conclusions. In contrast, inductive reasoning or induction is when a given statement or a set of repetitive occurrences help one define or identify a certain rule. In summary:
Deduction: A rule or general principle leads to a specific conclusion.
Induction: A specific example, or a set of repetitive occurrences lead to a rule or a general principle.
Abductive reasoning, on the other hand, is similar to inductive reasoning in the sense that conclusions are based on probabilities. In abductive reasoning, it is presumed that the most plausible conclusion is the correct one.
SyllogismsSyllogisms are one of the most popular and common forms of deductive reasoning tests. A syllogism is a certain form of argument that consists of a major premise, a minor premise and a logical conclusion. Using syllogisms is considered a good way to ensure validity when testing deductive reasoning.
Syllogism example question:
Major premise: All plants are photosynthetic
Minor premise: Algae are plants
Conclusion: Algae are photosynthetic
Seating Arrangement QuestionsAnother popular form of deductive reasoning questions is seating arrangements. These questions require you to arrange certain items or persons according to a set of given rules regarding their placements.
Seating arrangement example question:
Dan, Sam and Peter are standing in line.
Dan is not behind Peter.
Sam is last in line.
Who is standing first in line?
According to the above set of rules, there is only one logical way to arrange Dan, Sam and Peter in line: Dan is 1st, Peter is 2nd, and Sam is 3rd.
Test Content & Who is Likely to Sit the TestSome questions in a deductive reasoning test may be verbal while others may require numerical calculations. You would either receive questions in the syllogism format displayed above, or in a story format. This type of reasoning is commonly required in many different fields of work that require decision-making. Candidates applying for roles in industries such as Science and IT, Engineering, Software Development and Technical Design may be asked to take deductive reasoning tests as part of the assessment process.
