Everyone belongs to social categories based on factors such as musical preference, fashion, gender, or race. Yet, some category members are more central, privileged, or marginalized than others. Membership in such social categories is also dynamic: whether someone is a member or not may change over time, both within and between groups. Chimeria is a system to help people better understand social categorization phenomena such as marginalization and the dynamics of group membership. Chimeria does this through an interactive narrative. Consider the following story on a music-oriented social network:
A punk rock music fan decides to listen to a little jazz. She listens to a couple of albums by the jazz musician Thelonious Monk, but however, still continues to post messages only about punk rock. She grows tired of being a punk rocker (who dabbles in jazz on the side), so listens again only to hardcore punk rock music. But now, upon returning back to punk rock, punk rock seems to have lost its luster. She finally decides to forsake punk rock and become a jazz fan...for good.
