^The funny thing is that it is true. Everyone criticizes arranged marriage because it isn't initially based off of love, yet their divorce rates are so much lower.
Not that I'm a supporter of arranged marriage (I'm not, I do like the loved-based marriage idea).
I'm guessing that arranged marriages have lower divorce rates because couples feel obligated to stay together. It's like something that they bare because it's like their duty. Couples that get married for love get divorced when they don't feel like dealing with each other.
^Partially. Because the people who have arranged marriages do feel more inclined to stay together, they make more of a cooperative effort to create love and a family. They have to be a little more open-minded to even make the marriage work, and that allows their marriage to survie longer later.
People who have love-marriages selecrted each other because they were compatible with each other and didn't think they'd have to change their relationship drastically once they got married. Thus the less tolerance to change.
+1, arranged marriages often end up as being only economically driven => both the husband and wife live (a part of) their sexual life outside their relationship, and only stay together for economical and "cultural" reasons
