I’ve always been a fan of Tolkien, Star Trek, and other stories of alternate worlds, and I like to think this is related to my interest in intercultural communication. Parasocial Contact Hypothesis (Schiappa, Gregg, & Hewes, 2005) would lead us to believe that learning vicariously about others (perhaps even fictional groups) can help us develop empathy for those different from ourselves. Here’s an interesting take on the Lord of the Rings characters and their cultural groups. Perception and cultural differences are highlighted here… perhaps food for thought (or discussion) about how we group humans?
