The following video is part of our "Motley Fool Exclusive Interview" series.

In today's segment, Fool.com analyst Austin Smith interviews acclaimed author and New York Times columnist Charles Duhigg about his recent book The Power of Habit and the iEconomy series he's written for the Times.

Today, Charles looks at whether more big data will help or hurt the companies that have already mastered the art of studying consumer spending habits. Companies such as Wal-Mart and Target have had an edge over other retailers for years with their mountains of data, but with Big Data overflowing now, will that advantage evaporate?
