I’ve mentioned this sort of thing before. These exercises will allow you to examine, directly, your own thought-process with regard to certain hypothetical scenarios — while the parties that present these kinds of experiments are often quick to point out that there are no “right” or “wrong” answers, the disclaimer is somewhat misleading.
In a word, what you should be looking at is the consistency between your views. Without some metric by which to score the result, the exercise would be meaningless. Attempting to measure the relative validity or morality of a given values system would be equally pointless, since this would automatically bias the outcome. That said, this is an excellent example of how logic and reason can be employed to demonstrate how completely a given concept is understood and applied.
