Spotting Logical Flaws

Common Reasoning Errors

Arguments can look convincing but hide subtle mistakes called logical flaws. The LSAT loves to test your ability to find these errors.

Types of Flaws

  • Correlation vs. Causation: Assuming that because two things happen together, one causes the other.
  • Circular Reasoning: The conclusion is just a restatement of the premise.
  • False Dilemma: Presenting only two options when more exist.
  • Straw Man: Misrepresenting someone’s argument to make it easier to attack.

How to Spot Them

Ask yourself: Is the reasoning sound? Are there hidden leaps or tricks?

Beyond the LSAT

Recognizing flaws helps you avoid being misled in debates, news, and everyday decisions.

Examples

  • A doctor says, 'Every time I work late, it rains. Therefore, my work schedule controls the weather.' This confuses correlation with causation.

  • 'You must love dogs or hate animals' ignores the possibility of liking other animals—a false dilemma.

In a Nutshell

Logical flaws are errors in reasoning; learning to spot them is crucial for the LSAT and life.
