This is a misleading article in the following sense: the implication is "here are these seven surprising factors that are correlated with successful marriages". Except, in recent decades US divorce rates have bifurcated into two groups — well educated, affluent people who get married later and have lower divorce rates, and less well-off people who have a higher divorce rate. Given this one fact, most of the factors in the article are completely unsurprising. For example, it would be surprising if going on a honeymoon was not correlated positively with a successful marriage given that it is positively correlated with income.
