I had a conversation with one of my undergraduate students last week. She is Aremenian-American and in her culture, even in the US, there are many arranged marriages. I asked her if her marriage had been arranged. She told me that hers had not, but she had two older sisters. One had an arranged marriage and the other did not. This is NYC 2009.  The one with the arranged marriage has been married for 13 years with three children. They are reportedly happy. The other chose her husband and is divorced. 

This to say, while assessments are fine, I believe that, no matter how people answer these kinds of questions or perceive themselves to be, it is nearly impossible for people to really know what they are made of and how able/ready they are to commit to a lifelong marriage no matter what until the chips are down. No one can predict their reaction when faced with a sick child or other calamity. No one can predict their reaction when their spouses reaction is not what they expected. All of the assessment in the world still leaves commitment of one growing, changing, evolving human being to another growing, evolving human being. Talk about uncertainty.
