The harbinger of an unhappy marriage might be your gut.
A new study by psychologists found that newlyweds had underlying positive or negative gut feelings about their spouses that many are unaware of and that predicted their level of marital satisfaction years later.
The experiment used a photo of the newlywed spouse and a series of positive and negative words to elicit "automatic attitudes" — unfiltered, knee-jerk reactions that can sometimes oppose conscious thoughts.
