The core idea of social choice is:

Decisions of a group through aggregation of individual preferences to a collective decision.

Each member of a group has its own individual preferences. In order to come to a collective decision, it is necessary to aggregate them. For that purpose, different methods and designs exist:

• Condorcet Method
• Majority Vote
• Borda Count
• Coombs Method
• Instant Run off
• Coin-based voting
• Quadratic voting
• Rough Consensus
