The first thing to note is that your consistency score is 83%. This is higher than the average score for this test (where higher is better), which is 78%.
It is often thought to be a good thing if one's moral choices are governed by a small number of consistently applied moral principles. If this is not the case, then there is the worry that moral choices are essentially arbitrary - just a matter of intuition or making it up as you go along. Suppose, for example, you think it is justified to divert the train in the first scenario simply because it is the best way to maximise human happiness, but you do not think this justification applies in the case of the fat man on the bridge. The problem here is that unless you're able to identify morally relevant differences between the two scenarios, then it isn't clear what role the justification plays in the first case. Put simply, it seems that the justification is neither necessary nor sufficient for the moral judgement that it is right to divert the train.
You've done better than average in this test, but now is not the time to rest on your laurels, because let's face it, most people don't think very clearly about morality. However, before you embark on any further study(!) we suggest you check out the next page of analysis.
