Indeed. An example: I have a medical device that's producing an error. I check circuit A and find that it is not energized, so perhaps that's where the error originates. I replace circuit A and find that I have not fixed the error. Why? Because I didn't also prove that it's not untrue by checking another section of the device to see if the problem originated from before circuit A, cause as it turns out, switch B, which comes before circuit A, was damaged and is the component that needed to be replaced.
Long story short, don't assume that a conclusion is correct unless the evidence has also accounted for the possibility of an incorrect conclusion.
