It's interesting you say this. I read a book several years ago, I don't remember what it was. But it talked about how there used to be a lot of questions that were used to determine if someone was having a heart attack. They then did a lot of stats and number crunching and determined that with just 2 questions they could accurately predict whether or not someone was having a heart attack 95% of the time which was a considerable improvement. I wonder how many problems are we making worse by throwing more data at rather than making them better?
