Full Sail study attempts to shed light on Metacritic's weighting system

The website Metacritic weights the scores of different video game critics and publications when calculating its aggregate 'metascore' for any particular title.
[Update: Metacritic has responded to the study, claiming that the information is "wildly, wholly inaccurate." The full statement can be found on Facebook.] The website Metacritic weights the scores of different video game critics and publications when calculating its aggregate 'metascore' for any particular title. Each critic/ publication is assigned one of six different weightings of 'importance', with some publications exerting considerably more influence over a game's final 'metascore' than others. This was revealed by Adams Greenwood-Ericksen of Full Sail University at a talk titled 'A Scientific Assessment of the Validity and Value of Metacritic' delivered at the Game Developer's Conference in San Fransisco this afternoon. Metacritic confirmed to Greenwood-Ericksen during the course of his research that the site applies different weightings to incoming critics and publications' reviews in order to calculate its 'averaged' numerical score for any particular title. However, it would not reveal how the weightings were assigned to different publications or on what criteria one critic was given a greater weighing than another. The course director and his students then set about modelling the weightings based on data pulled from the site. Finally, after six months of work, the researchers compared their modeled scores to the actual scores and discovered that across the 188 publications that feed into Metacritic's video game score work, their findings were almost entirely accurate. Greenwood-Ericksen stated they wanted to carry out the research as Metacritic scores are "very important to a lot of people" and pointed out that, when publishers withhold financial bonuses when a game doesn't reach its Metacritic target, livelihoods are tied up in the site's work. He also reminded attendees that often a publisher's Wall Street stock can change on the basis of a Metacritic score., and as such the site's workings are of practical interest. The findings will also be of interest to consumers as, if accurate, they reveal that some official magazines and sites (which are sponsored by platform holders in some cases) are assigned a greater weighting than independent sites and critics. Here is the full listing of score weightings used by Metacritic according to Greenwood-Ericksen's research: Weighting -- Critic/ Publication Highest (1.5) -- Dark Zero Highest (1.5) -- Digital Chumps
