CONDORCET (Condorcet Method — Pairwise majority winner from ranked ballots) is a aggregationoperator multi-criteria decision-making (MCDM) method introduced by Marquis de Condorcet in 1900. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

Key highlights

  • Follows a transparent, reproducible computational procedure that can be audited step by step.
  • Handles multiple criteria of differing scales and units within a single decision matrix.

When to use it

The Condorcet criterion is the gold standard for pairwise voting: a Condorcet winner — when it exists — is universally considered the legitimate group choice. The drawback is the Condorcet paradox: cyclic majorities (A>B>C>A) can prevent any winner. Use Schulze, Kemeny, or Copeland to break ties when no Condorcet winner exists.

Strengths & limitations

Strengths
  • Follows a transparent, reproducible computational procedure that can be audited step by step.
  • Handles multiple criteria of differing scales and units within a single decision matrix.
Limitations
  • Results depend on the chosen normalisation, weights, and parameter settings.
