Preference Ordering

A ranking of alternatives that a decision maker holds, ideally satisfying completeness (every pair is comparable) and transitivity (if A is preferred to B and B to C, then A is preferred to C).

Why it matters

A coherent preference ordering is the foundation of rational choice; inconsistent preferences make any decision tool unreliable and expose the agent to money pumps.
