Researchers at North Carolina State University claim they've found a way to predict your in-game behavior with "up to 80 percent accuracy." After analyzing the decision-making of 14,000 World of Warcraft players, they noticed that different players prefer different types of achievements. These preferred achievements clump together into statistically significant groups, known as "cliques", even if they have nothing obvious in common. So a WoW player who likes to improve their unarmed combat skills also, for some psychological reason, tends to want points for world travel. What's more, the researchers believe that clique-spotting can be exploited outside the rather specific world of WoW, in which case their method could prove lucrative to game designers, online retailers and pretty much anyone with an interest in predicting your next move.
