Target knows when you are pregnant

Cool article on how companies are mining consumer shopping data. New Yorkers, beware of your Duane-Reade frequent shopping card!

Best bit from the article: “The reason Target can snoop on our shopping habits is that, over the past two decades, the science of habit formation has become a major field of research in neurology and psychology departments at hundreds of major medical centers and universities, as well as inside extremely well financed corporate labs. “It’s like an arms race to hire statisticians nowadays,” said Andreas Weigend, the former chief scientist at Amazon.com. “Mathematicians are suddenly sexy.””

Clearly this is something my undergraduates need to know!
