I can’t imagine any other example where people voluntarily move for a black box approach.
Imagine taking a picture on autoshot mode and refusing to look at it. If the client doesn’t like it because it’s too bright, tweak the settings and shoot again, but never look at the output.
What is the logic here? Because if you can read code, I can’t imagine poking the result with black box testing being faster.
Are these people just handing off the review process to others? Are they unable to read code and hiding it? Why would you handicap yourself this way?
The output of code isn't just the code itself, it's the product. The code is a means to an end.
So the proper analogy isn't the photographer not looking at the photos, it's the photographer not looking at what's going on under the hood to produce the photos. Which, of course, is perfectly common and normal.
I've found that focusing my attention upstream (specs, constraints, test harness) yields better outcomes than poring over implementation details line by line. The code is still there if I need it. I just rarely need it.
