Xenophile is a person who is attracted to foreign peoples, cultures or customs. That's one of the best things a writer can be because it allows us to better understand the universal nature of people.
And it makes incredible opportunities for world building. Because, I'm not sure if you are like me, but the setting of my book isn't where I live.

Think about some of the best world builders - George Lucas. Take just a moment to think about the different cultures he presents in his saga. Even when they look really bizarre, feel strange and unfamiliar, people are still drawn to them because of the feeling of familiarity amid the strange.
That is what we need to create in our works, whether it's contemporary or speculative or non-fiction. And it is a skill best honed by paying attention to other cultures.
