IMHO there are problems with arranged marriages - for one thing I personally don't believe that a few supervised visits are sufficient to really determine if you want to spend the rest of your life with someone.

But, the numbers do speak for themselves - divorce rates are much lower for arranged marriages. Perhaps there is social pressure preventing divorces in that context, but IMHO the objective, neutral third-party assessment of your potential partner plays into that as well. "We love each other so things will work out" is a nice thought, but often not reality.

That being said, I'm culturally ingrained to find my own mate, so that's that for me :P
