 With these distinctions in mind, we can see the relevance of experimental evidence to investigations in this area. First and perhaps most obviously, experiments can investigate our intuitions about what constitutes a good life, thereby giving us insight into the ordinary concepts of happiness, well-being, and flourishing. To this end, Phillips, Nyholm, and Liao (2014) investigated intuitions about the relationship between morality and happiness. Their results suggest that the ordinary conception of happiness involves both descriptive and normative components: specifically, we judge that people are happy if they are experiencing positive feelings that they ought to experience. So, to use their examples, a Nazi doctor who gets positive feelings from conducting his experiments is not happy. By contrast, a nurse who gets positive feelings from helping sick children is happy, though a nurse who is made miserable by the same actions is not happy.
