What is the connection between district magnitude and the permissiveness of an electoral system?

Question

Quizplus · Accepted Answer

When district magnitude (the number of representatives elected from each district) is high, it is more permissive because there is a greater chance for smaller parties to win seats. In contrast, when district magnitude is low, there are fewer opportunities for smaller parties to gain representation, making the system less permissive. Therefore, a higher district magnitude allows for a more permissive electoral system.
