Consulting your intuition in a matter of descriptive questions should be done with caution. (But even then, it’s not forbidden or even really discouraged, since intuition can offer valuable—if non-rigorous—insights.) Using your intuition when confronting normative or prescriptive problems, on the other hand, is perfectly fine, because there’s no “should” without an intuition about what “should” be. (Unless, of course, you think that normative problems are also descriptive, in which case you believe in objective morality, which has its own problems.)
