Generic descriptions (e.g., “girls are emotional”) are argued to play a major role in the development of essentialist reasoning about social categories (Rhodes et al., 2018). However, studies have been conducted dominantly in English-speaking communities and among Western samples. This is a significant limitation given that a number of theories focus on the linguistic form of generic statements and distinguish between form and content in leading to essentialism. In this study, we plan to extend the research on generics and social essentialism beyond English-speaking, Western samples. We aim to explore how generic statements with different content (biological or cultural) about a novel social category may lead to essentialist beliefs among children and adults in Iran, a Persian-speaking community that is underrepresented in the literature. Using a design similar to Noyes & Keil (2020), we plan to expose 4 to 9-year-old children (N = 104) and adults (N = 104) to generic or specific statements (between subjects) ascribing biological or cultural features to a novel social category. We will measure the degree to which exposure to these statements leads to essentialist reasoning in terms of inheritability and “kindhood”. This work contributes to diversifying the field and informs theories of social essentialism.
