The advantages of majoritarianism include its potential for efficient decision-making and the promotion of stable governance, as it often leads to clear majority support for policies. This can enhance political accountability. However, disadvantages include the risk of marginalizing minority voices and interests, leading to potential discontent and instability. Majoritarian systems may simplify complex political landscapes, underserving diverse opinions. Furthermore, they can foster legislative gridlock when majorities clash, undermining broader democratic principles of representation and inclusiveness.
