Notes on Observations and Judgments

Here is a question to ponder...
At what point does an observation become a judgment?
What we choose to observe is a judgment as well as the choice in language we use to describe it. In radio we want to "paint" a visual for our listener. What happens when our description works so well because it may rely on certain stereotypes? I believe one of the biggest fears of a documentarian is confirming a stereotype.
Any thoughts?
