Generally speaking, in cultures that practice arranged marriage, marriage is regarded primarily as an economic arrangement, not a romantic one. (This isn’t to say, of course, that romance isn’t a factor in some arranged marriages.) In addition, according to Dr. Fisher, cultural attitudes about individualism versus collectivism are at play. In the West, people tend to marry to fulfill themselves, while in some non-Western cultures, “one’s primary responsibility is to the group — one’s parents, kin group, ancestors and others.”
With that said, it’s important to distinguish between countries and cultures when talking about such a diverse, ever-evolving cultural practice. There are numerous shades of arranged marriages, just as there are numerous shades of self-selected marriages.
