Researchers in Italy found an equation that narrows down the main predictors of break-ups. The first most important factor is the life satisfaction of both partners, the second is how much housework the female does. They used AI to determine what was most important in over 2,000 relationships that they studied over the course of 12 years. All of the couples were either married or cohabitating. Of the 2,038 pairs, 914 broke-up by the end of the study. Which is on par with divorce rates. Interestingly, personality traits didn’t have a huge impact on break-ups as much as other things.
