Real Data Mining

I don’t know where Marissa Mayer read that, apparently…

credit card companies know with 98% accuracy two years before that you’re going to get divorced.

But I see a business model here. We should put real data mining to action. What if you and your boyfriend or girlfriend could submit your credit card purchases before you got married and could get an educated guess from them about the chances – how much more or how much less than the standard 50%? – of your future marriage falling apart?
