This sort of analysis is (perhaps surprisingly) used in hospitals. They apply a rule “don’t test if it won’t change the treatment”. My partner works in a hospital and she was talking about an elderly woman they had with classic cancer symptoms. There was a simple test that would tell them if she had the cancer or not. They did not do the test, because the treatment they would provide wouldn’t change (she needed treatment for something else, which would have taken priority anyway).
