Two things happened to Sandra Bullock this month. First, she won an Academy Award for best actress. Then came the news reports claiming that her husband is an adulterous jerk. So the philosophic question of the day is: Would you take that as a deal? Would you exchange a tremendous professional triumph for a severe personal blow?

On the one hand, an Academy Award is nothing to sneeze at. Bullock has earned the admiration of her peers in a way very few experience. She’ll make more money for years to come. She may even live longer. Research by Donald A. Redelmeier and Sheldon M. Singh has found that, on average, Oscar winners live nearly four years longer than nominees that don’t win.

Nonetheless, if you had to take more than three seconds to think about this question, you are absolutely crazy. Marital happiness is far more important than anything else in determining personal well-being. If you have a successful marriage, it doesn’t matter how many professional setbacks you endure, you will be reasonably happy. If you have an unsuccessful marriage, it doesn’t matter how many career triumphs you record, you will remain significantly unfulfilled.

This isn’t just sermonizing. This is the age of research, so there’s data to back this up. Over the past few decades, teams of researchers have been studying happiness. Their work, which seemed flimsy at first, has developed an impressive rigor, and one of the key findings is that, just as the old sages predicted, worldly success has shallow roots while interpersonal bonds permeate through and through.
