The paper explores the complexities of aggregating individual preferences into a collective social preference ordering in democratic processes. It highlights how different voting rules can yield varying social outcomes, raising questions about legitimacy and the ideal voting method. The work references Arrow's criteria for democratic legitimacy, asserting that while certain voting rules may meet desirable qualities, no single rule can fulfill all conditions simultaneously. This tension underscores the challenges inherent in achieving a fair and representative democratic decision-making process.
