Spotting Logical Fallacies

What are Logical Fallacies?

Logical fallacies are errors in reasoning that undermine the logic of an argument. The LSAT loves to test your ability to spot these sneaky mistakes!

Common Fallacies on the LSAT

  • Causation vs. Correlation: Just because two things happen together doesn’t mean one caused the other.
  • Circular Reasoning: The conclusion just repeats a premise.
  • False Dilemma: Pretending only two choices exist when there are more.

How to Spot Them

Watch for arguments that make leaps, ignore alternatives, or rely on shaky evidence.

Why It Matters

Being able to identify fallacies helps you avoid being misled in debates, advertisements, and news.

Real-World Scenarios

Whether you’re evaluating a political ad or an online review, spotting fallacies keeps your reasoning sharp.

Examples

  • A commercial says, 'People who drink this soda are happier. So, drinking this soda makes you happy.' (Causation vs. Correlation)

  • A politician says, 'We must ban this app or risk the collapse of society.' (False Dilemma)

In a Nutshell
