Researchers have developed a method to formally explain why a candidate might lose in a tournament, even when considering different completion scenarios. This involves identifying "destructive minimal supports," which are sub-tournaments where a candidate's loss is independent of other participants. The study provides characterizations for six common tournament solutions, determining when a candidate is a necessary loser or a possible winner, and offers algorithms for computing these supports, though the Borda rule case is suspected to be NP-complete.
