Humans learn about the world through inductive reasoning, generalizing information about an individual to others in the category. Indeed, by infancy, monolingual children expect people who speak the same language (but not people who speak different languages) to be similar in their food preferences (Liberman et al., 2016). Here, we ask whether infants who are exposed to linguistic diversity are more willing to generalize information even across language-group lines. To test this, we ran an inductive inference task and collected data on exposure to linguistic diversity at the interpersonal and neighborhood levels. Infants with more linguistically diverse social networks were more likely to generalize a food preference across speakers of different languages. However, this relationship was not seen for neighborhood diversity. We discuss implications of this work on understanding the development of bias and its malleability based on early social experiences. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
