Nu există un sistem electoral care să fie complet echitabil. Demonstrația unor matematicieni

Mathematicians have proven that no electoral system can perfectly balance local representation, national proportionality, and a fixed number of parliamentary seats once the number of competing parties exceeds a certain threshold. Their analysis indicates that achieving a completely fair electoral system is mathematically impossible, as any voting method involves trade-offs. Recent elections in Northern Europe have highlighted these tensions, particularly as voters increasingly split their votes among more parties. Researchers suggest that while a perfect system may not exist, states can better manage the conflict between regional representation, proportionality, and parliamentary size. They propose an alternative algorithm aimed at improving current electoral systems, though it may compromise local representation.
