Advanced Conditional Reasoning

Going Deeper with Conditionals

Some LSAT questions use multiple, nested, or tricky conditional relationships.

Advanced Patterns

  • Multiple Conditions: "If A and B, then C."
  • Unless/Except/Until: These often mean negation or require diagramming.

Formula: \(A \rightarrow B\), \(C \rightarrow eg B\), so \(C \rightarrow eg A\)

Contrapositives and Chains

Linking multiple conditionals creates "chains" (\(A \rightarrow B \rightarrow C\)), letting you deduce new relationships.

Why It’s Useful

Mastering these lets you untangle even the most complex LSAT setups and apply similar logic in real-life planning and troubleshooting.

Key Formula

\[A \rightarrow B, C \rightarrow eg B, \text{ so } C \rightarrow eg A\]

Examples

  • If you win the lottery, and if you buy a ticket, then you'll be rich. (Win lottery AND buy ticket → Rich)

  • No one can enter unless they have a ticket. (Not have ticket → Not enter; contrapositive)

In a Nutshell

Handle even the trickiest conditional logic like a pro.
