The Open-Source Psychometrics Statistical 'Which Character' Personality Quiz gained massive viral popularity on platforms like Twitter, TikTok, and Tumblr. Unlike standard quizzes, this one uses a massive database of user-rated character traits to provide a statistical match based on psychological dimensions. The meme aspect emerged when users began sharing their results, often expressing shock, humor, or self-deprecation when the algorithm matched them with morally ambiguous characters, villains, or highly specific unhinged archetypes. It has become a staple for internet subcultures to kin or identify with their top results, turning a psychological data project into a viral tool for digital self-expression and self-deprecating humor.
