Or, at the very least, you’ve probably given some amount of serious thought to the list of qualities and characteristics you’d like your feel would be ideal for your husband or wife to possess. Your list might include things like common interests, matched levels of ambition, and intense physical attraction; the possibilities are truly endless. But did you know that it’s been scientifically proven that marrying someone with one very specific personality trait can help you boost your salary by as much as $4,000 per year? Yes, you read that correctly. Researchers Brittany C. Solomon and Joshua J. Jackson from Washington University in St. Louis found that a person who marries a conscientious spouse is 50% more likely to get a promotion than someone whose spouse is more careless.

These results demonstrate that the dispositional characteristics of the person one marries influence important aspects of one’s professional life.” This all sounds pretty great on paper, but how can this information be put to even better use on a bigger scale? Solomon, herself suggests that if employers better understand the positive effects our personal relationships can have on our performance at work, “they might be more receptive to policies like flextime and telecommuting that make it easier for employees to spend time with their significant others.” That makes plenty of good sense to us.
