There is no privileged link between kinds and essences early in development.

According to the dominant view of category representation, people preferentially infer that kinds (richly structured categories) reflect essences. Generic language ("Boys like blue") often occupies the central role in accounts of the formation of essentialist interpretations-especially in the context of social categories. In a preregistered study ( = 240 American children, ages 4 to 9 y), we tested whether children assume essences in the presence of generic language or whether they flexibly assume diverse causal structures. Children learned about a novel social category described with generic statements containing either biological properties or cultural properties. Although generic language always led children to believe that properties were nonaccidental, young children (4 or 5 y) in this sample inferred the nonaccidental structure was socialization. Older children (6 to 9 y) flexibly interpreted the category as essential or socialized depending on the type of properties that generalized. We uncovered early-emerging flexibility and no privileged link between kinds and essences.
