Another study, from Reuter’s, says that personality is the key to marital bliss.

“Shared moral values are less important than compatible personalities as a recipe for a good marriage, according to a study released on Sunday.

Married couples often share the same attitudes about faith and other values, researchers from the University of Iowa found. But those with personalities similar to their spouses were the happiest.”

The study used self-description of marriage, five months into the marriage, by couples who dated an average of 3.5 years.
