You only have two choices, look at data you don't control or data you do. The entire point of experiments is to narrow the range of uncontrolled data as much as possible. Looking at raw data does not help. Looking at huge data-sets of minimally controlled experimental data does not help.
Physicists's for example can't change the age of the universe they are operating in. It's a rather large unknown, but not exactly an unknown unkown.
At the other end, people trust surveys of eating habits. I don't care if you send out a billion of those things it's still bad data in systematic and changing ways.
In between, most animal studies in mice are looking at disease analog X, in a population of fat, minimally stimulated, etc.
