Savvy consumers all know that their lifetime debt history ends up in their credit score, and that lenders use that score to try to predict if someone is a good bet for a big loan like a mortgage. But even the most-connected consumer may not realize how many hundreds of other scores we all now trail in our wakes too, thanks to the advent of big data. Do you know, to the last decimal, how likely are you to buy jewelry? To sign up for cable? To have a kid in the next year? Someone, somewhere, is tallying all of that information about almost everyone. But good luck finding out what’s out there, who’s scoring it, and if your numbers are even actually about you at all.
