The first failing of the Voight-Kampff test is that often it is not measuring whether or not subjects respond correctly to the questions, but how quickly they do so. But only after a pause. The reaction had come too late. This delayed reaction time of nerves is also what is tested by the Boneli Reflex-Arc Test. We try it a number of times, of course.
Elapsed time varies in both the andy and the human.
But by the time ten reactions have been measured, we believe we have a reliable clue. Not getting the correct reaction time gives them a clue as to how to interpret their test results. On top of this uncertainty is the irrelevance of this reaction time anything other than proving that there is a microsecond of difference between the nerve response of a human and an android. It seems that the tests really reinforce the essential sameness of the androids while the testers are desperately searching for some slight difference in physiology and direction of empathy on which they can base their discrimination. The second flaw of the Voight-Kampff test is its reliance on the idea of a concrete moral standard.
