How are the results decided?
Voting for the Hugos is a two-stage process. In the first stage voters may nominate up to five entries in each category. All nominations carry equal weight. The five entries that get the most nominations in each category go forward to the final ballot. In the final ballot voting is preferential. Voters rank the candidates in order of preference. The system for counting the votes is quite complicated but it is designed to ensure that the winner has support from the majority of voters. A full description of the counting procedure is available on this site.
