Does It Matter How We Speak About Social Kinds? A Large, Pre-Registered, Online Experimental Study of How Language Shapes the Development of Essentialist Beliefs
A problematic way to think about social categories is to essentialize them—to treat particular differences between people as marking fundamentally distinct social kinds. From where do these beliefs arise? Language that expresses generic claims about categories elicits some aspects of essentialist thought, but the scope of these effects remains unclear. The present study (N = 204, ages 4.5-8 years, tested via a new online lab) found that generic language increases two critical aspects of essentialist thought, including beliefs that (1) category-related properties arise from intrinsic causal mechanisms and (2) category boundaries are inflexible. These findings have implications for understanding the spread of essentialist beliefs across communities and the development of inter-group behavior.
