Let us say you have Google or even Facebook – you have a billion users. It is almost impossible for Google and Facebook to understand whom their customers are. Intuition or even just like talking to some customers is going to give you an extremely biased view. You are going to basically base your entire description of one billion people based on interactions with what a hundred people? Having the data and the numbers are really important. Like we said previously, completely trusting the numbers and the analysis is also very foolish. You need human intelligence to interpret these numbers. It is really an interplay of the numbers and your interpretation because ultimately, even though the numbers will never give us cause of information – they can never really tell you with certainty that A causes B, it would tell you that A is related to B. It is human interaction that is needed that kind of tie these things all together into a credible story. Forget the notion that you will find one story that is correct, and everything else is wrong. All we are trying to look for is a story that is our best story, given our constraints of what we can and what we cannot.
