Preference Aggregation

Preference aggregation is the process of combining individual preferences or opinions into a collective decision. Imagine a group of people voting on their favorite movie. Each person has their own choice, but to reflect the group's overall preference, a method is used to tally these choices. This can involve straightforward voting, ranking options, or using more complex mathematical approaches. The goal is to find a fair way to determine what the majority prefers, ensuring that everyone's views are considered in the final outcome. It’s widely used in areas like voting systems, decision-making, and social choice theory.
