The Best Way of Knowing If Your Marriage Is Going to Make It

The question of what makes love last has been asked by everyone from psychologists to philosophers to poets and writers, and now, even mathematicians are attempting to determine what makes the difference between a love that goes the distance and one the flames out.


After years of research and a complex mathematical formula, researcher Hannah Fry thinks she has the answer. And it is something you probably could have told her -- no math required.

Fry, who gave a popular TED Talk on the "Mathematics of Love" last summer, discovered that couples that have more positive interactions with each other are more likely to last, whereas couples with more negative interactions are at high risk of failure.

Here's her Talk in full.

Yeah. Happy couples are ... happier? Color me shocked!

Fry does point out one finding that is good to bear in mind, in terms of keeping a long-term relationship on track: the importance of giving your partner the benefit of the doubt. As she notes:

In relationships where both partners consider themselves as happy, bad behavior is dismissed as unusual. In negative relationships, however, the situation is reversed. Bad behavior is considered the norm.

And relationships that are less likely to last are the ones in which couples get so fed up with each other during an argument that they don't even put in the effort to talk it out.

So, the next time your partner is grouchy or short-tempered, pay attention to whether you chalk that up to a bad day, or if you think that he is just being that way to annoy you, or because he is always that way. The answer might tell you something about your future.

What do you think is the best predictor of whether love will last?
