I just got back from my cousin’s wedding. While not in a church, it was otherwise a traditional Christian marriage, with many of the rituals often included. I hypothesize that traditions and rituals serve as strong attractors of universes in which those same traditions and rituals are practiced. Therefore by having a marriage ceremony filled with rituals that have been followed for centuries, it’s likely that in nearby universes a very similar marriage ceremony is taking place. Contrast this with the couple who doesn’t have a ceremony and instead spontaneously decides one day to get married at the court house without any ritual. I hypothesize that this non-ritualistic marriage will be surrounded by much fewer nearby universes in which the couple is married, and therefore it is more likely that the couple will find themselves in a universe where they are not married.
