"So credit-card firms are changing their business plans. Gone are the days of handing out cards willy-nilly and hoping that the cardholders who dutifully pay up will offset the losses from those who default. Today companies are focusing on those customers most likely to honor their debts. And they are looking for ways to convince existing cardholders that if they only have enough money to pay one bill, it’s wiser to pay off their credit card than, say, the phone." - Raymond from Bookmarklet

"Put another way, credit-card companies are becoming much more interested in understanding their customers’ lives and psyches, because, the theory goes, knowing what makes cardholders tick will help firms determine who is a good bet and who should be shown the door as quickly as possible." - Raymond

"The exploration into cardholders’ minds hit a breakthrough in 2002, when J. P. Martin, a math-loving executive at Canadian Tire, decided to analyze almost every piece of information his company had collected from credit-card transactions the previous year. Canadian Tire’s stores sold electronics, sporting equipment, kitchen supplies and automotive goods and issued a credit card that could be used almost anywhere. Martin could often see precisely what cardholders were purchasing, and he discovered that the brands we buy are the windows into our souls — or at least into our willingness to make good on our debts. His data indicated, for instance, that people who bought cheap, generic automotive oil were much more likely to miss a credit-card payment than someone who got the expensive, name-brand stuff. People who bought carbon-monoxide monitors for their homes or those little felt pads that stop chair legs from scratching the floor almost never missed payments. Anyone who purchased a chrome-skull car accessory or a “Mega Thruster Exhaust System” was pretty likely to miss paying his bill eventually." - Raymond
