Imdb-n a filmértékeléseknél miért a súlyozott átlagot veszik figyelembe, miért nem az átlagot?

ennyit írnak a témáról:

IMDb publishes weighted vote averages rather than raw data averages. Various filters are applied to the raw data in order to eliminate and reduce attempts at 'vote stuffing' by individuals more interested in changing the current rating of a movie than giving their true opinion of it.

The exact methods we use will not be disclosed. This should ensure that the policy remains effective. The result is a more accurate vote average.
