In spite of all the griping and jokes to the contrary, married people are happier than unmarried or no longer married people - much research shows this. Likewise, married people are much more likely to be conservative than are unmarried people.
The most unusual finding is that extremes - left and right - are happier than moderates. As Brooks says, perhaps in partial jest:
Extremists have the whole world figured out, and sorted into good guys and bad guys. They have the security of knowing what’s wrong, and whom to fight. They are the happy warriors.No wonder the country is polarized and becoming more so.
