Yes, humans have found that you don't need officially stamped statistics (and in many cases they're unreliable or "doctored" anyway), and that they can make general observations on their own, through something they call experience.

And a near universal experience with doctors for anybody paying attention is that.

One can reject it or accept it and improve upon it after checking its predictive power, or they can pause their thinking and wait for some authority to give them the official numbers on that.
