The data scientist Randal Olson recently visualized some of the findings from a paper by Andrew Francis and Hugo Mialon, two researchers at Emory University who studied 3,000 married couples in the U.S. to determine the factors that predicted divorce. They analyzed income, religious attendance, how important attractiveness was to each partner, wedding attendance, and other metrics to determine the aspects associated with eventual marital dissolution.
Their findings offer some take-aways for couples who want to minimize their chances of divorce: You should date for three years before popping the question. Be wealthy, but don't be a gold-digger. Have a huge wedding, but make sure it's cheap. And whatever you do, don't skip the honeymoon.
