What big data brings to the table is you can find that "A" is strongly correlated with "B" and have not even an inkling as to why.
If you scan all medical and personal records throughout history and find that everyone that owns a yellow Camero (no matter what year) at some point in their life comes down with liver cancer at 45. Sure you can make up reasons all you want but if there is no other correlation in the data, do you just ignore it? What if it's just 90% of the Camero owners? even 50% or 20% would still be a significant correlation to start asking about car ownership history.
