äänestysteorian

Äänestysteoria, often translated as voting theory or the theory of voting, is a field of study that analyzes voting systems and the outcomes of elections. It explores how different voting rules can lead to different results and examines the fairness and efficiency of various electoral mechanisms. Key concepts within voting theory include voter preferences, strategic voting, and the properties of voting systems such as Arrow's impossibility theorem, which demonstrates that no ranked voting system can satisfy a set of desirable fairness criteria simultaneously.

Researchers in voting theory use mathematical and logical frameworks to understand collective decision-making processes. They investigate paradoxes that can arise in elections, such as the Condorcet paradox where a majority may prefer candidate A over B, B over C, and C over A, leading to no clear winner. Different voting systems, like plurality voting, ranked-choice voting, and approval voting, are evaluated based on criteria such as the ability to elect a Condorcet winner, resistance to manipulation, and representativeness. The field has applications in political science, economics, and computer science, contributing to the design and understanding of democratic processes and other forms of collective choice.
