The Science of Celebrity Break-ups

"The equation’s variables included the relative fame of the husband and wife, their ages, the length of their courtship, their marital history, and the sex-symbol factor (determined by looking at the woman’s first five Google hits and counting how many show her in skimpy attire, or no attire)... The 2006 equation correctly predicted doom for Demi Moore and Ashton Kutcher; Pamela Anderson and Kid Rock; and Britney Spears and Kevin Federline. It also forecast that Will Smith and Jada Pinkett would probably not make it to their 15th anniversary, in December 2012; so far, they’re still married, but gossip columns are rife with reports of a pending split... It turns out that overall fame doesn’t matter as much as the flavor of the fame. It’s tabloid fame that dooms you. Sure, Katie Holmes had about 160 Enquirer hits, but she had more than twice as many NYT hits. A high NYT/ENQ ratio also explains why Chelsea Clinton and Kate Middleton have better chances than the Kardashian sisters... Besides the wife’s tabloid fame, the crucial ones are the spouses’ combined age (younger couples divorce sooner), the length of the courtship (quicker to wed, quicker to split), and the sex-symbol factor (defined formally as the number of Google hits showing the wife “in clothing designed to elicit libidinous intent”).” — New York Times
