The basics

What is the Logical Reasoning Test?

Logical reasoning measures how well you spot valid inferences, evaluate argument structure, and work through chains of conditions to a sound conclusion. It underpins case interviews, LSAT-style admissions, and most analytical roles.

JobCannon's 25-question test covers four sub-skills: classical syllogisms, conditional ("if-then") logic, deductive inference from text, and analytical puzzles. Each item has one correct answer scored 3 points; your overall percentile maps to a five-tier band from Developing to Exceptional.

The format mirrors LSAT Logical Reasoning, Watson-Glaser Critical Thinking, and consulting case interviews. Practising here doubles as preparation for any of them. No login, no email, instant score.

  • 25 questions split into four sub-skills: syllogisms (6 items), conditional logic (6 items), deductive inference (6 items), and analytical puzzles (7 items). Most people complete it in about 5 minutes.

  • It is the same family of assessment. The LSAT Logical Reasoning section, Watson-Glaser Critical Thinking, and most consulting case-interview screens all measure the same underlying ability: evaluating argument structure and inference quality. JobCannon's questions are shorter than LSAT stimuli but test the same skills.

  • Deductive reasoning starts with general rules and applies them to specific cases, if all premises are true, the conclusion must be true. Inductive reasoning starts with observations and infers a general pattern, the conclusion is probable, not certain. This test focuses on deductive reasoning, which is what employers and admissions tests typically measure.

  • Law, management consulting, software engineering, data science, academic research, intelligence analysis, and product strategy. Anywhere you need to evaluate evidence, spot flawed arguments, and build sound recommendations from incomplete information.

  • Scores map to five percentile tiers: Developing (0–20%), Average (21–40%), Above Average (41–60%), Superior (61–80%), and Exceptional (81–100%). Law, consulting, and software roles tend to expect Above Average and up. The sub-scores, syllogisms, conditional logic, deductive inference, and analytical puzzles, tell you which form of reasoning to sharpen.

  • Syllogisms test validity, not truth, whether the conclusion must follow from the premises, regardless of whether the statements match the real world. The fastest approach is to take each premise literally, ignore outside knowledge, and check whether a counterexample is possible. If you can imagine the premises being true while the conclusion is false, the argument is invalid.

  • It overlaps with one part of it. Logical reasoning is a core component of fluid intelligence, your ability to reason and solve novel problems, which is what a full IQ test samples more broadly. A strong logical reasoning score is a good signal of general reasoning ability, but an IQ test also covers verbal, numerical, spatial, and abstract domains for a wider picture.

  • No. Each correct answer is worth 3 points and wrong answers score 0, with no negative marking. Answer every item, eliminate the clearly invalid options and choose your best remaining candidate.

  • Within a session the test is single-attempt so your score reflects a real first run rather than a memorised retry. You can take it again in a fresh session to track progress, but treat your first sitting as the clean baseline.
