Filmmaker: I use hidden cameras when filming documentaries, because people behave differently when they are aware of being filmed. Although my subjects have been told that a camera is present, they remain unaware of its location and act naturally. Hence, my documentaries for example, people speak directly to the camera.
What this question is testing
Evidence
Hidden cameras mean the subjects do not know where the camera is. They act naturally. Meanwhile, in other documentaries, people talk straight to the camera and clearly know they are being filmed.
Conclusion
Therefore the hidden-camera documentaries are more worthwhile.
Evaluate
The argument says "my subjects act naturally" and concludes "my documentaries are better." But why does natural behavior make a documentary better? Maybe the most worthwhile documentary is one about an important topic where people speak directly to the camera with prepared, thoughtful statements. The argument needs a principle that says natural = worthwhile.
Goal
Find the answer that bridges authentic behavior to documentary quality.
