As a person who often suffers from analysis paralysis, I'm attuned to the incredible wealth of data that is available to marketers. In his great book The Signal and the Noise, Nate Silver discusses some of the challenges that data points present to all statisticians. He also makes the case the statistics alone aren't as helpful to predicting outcomes as statistics that are augmented with experiential data points. In the context of marketers, there is good reason that they are overwhelmed. There is a lot of noise and not a lot of signal.
I'm curious to know your experiences with this. Is marketing data overwhelming and if so, can it be managed?
