Research suggests that many social concepts, such as FRIEND and ARTIST, have two independent sets of criteria for their application: one descriptive, and one normative. These have become known as “dual character concepts.” Recently, it has been argued that HUMAN is a dual character concept, and that this engenders a distinctively normative variety of dehumanization (Phillips, 2022). In what follows, I develop this model by examining which form of essentialism drives normative dehumanization. In particular, I focus on three candidates: Platonic essentialism; teleological essentialism; and value-based essentialism. Across four experiments, I found evidence that normative dehumanization is driven by value-based essentialism, as opposed to Platonic or teleological essentialism. I also found evidence that normative dehumanization is a unique predictor of intergroup hostility, over and above like/dislike; as well as perceptions of ideal humanness, and typical humanness. Together, these findings clarify the ordinary concept of a “true human,” and thus what it means to normatively dehumanize someone. These findings also suggest that research concerning intergroup hostility will benefit from focusing on the distinction between descriptive and normative dehumanization.
