Logical Reasoning Fundamentals
What is Logical Reasoning?
Logical Reasoning is a core section of the LSAT that tests your ability to analyze and evaluate arguments. You'll read short passages and then answer questions that require you to identify assumptions, flaws, strengthen or weaken arguments, and more.
Key Concepts
- Arguments: Understanding how premises support conclusions.
- Assumptions: Unstated ideas that must be true for the argument to work.
- Flaws: Common mistakes in reasoning, like confusing correlation with causation.
Why It Matters
This skill is essential for law school and beyond, as lawyers must spot weak arguments and construct strong ones.
Typical Question Types
- Identifying the main point
- Detecting flaws
- Strengthening or weakening arguments
Practice Makes Perfect
Try reading an editorial and asking yourself: What is the author's main conclusion? What evidence supports it? Is there a logical leap?
Examples
Spotting a hidden assumption in a politician’s speech.
Identifying the flaw in an advertisement’s claim.
