Abstract
AbstractStereotypes can exert a powerful influence on our interactions with others, potentially leading to prejudice when factual evidence is ignored. Here, we identify neuroanatomical and developmental factors that influence the real-time integration of stereotypes and factual evidence during live social interactions. The study uses precisely quantified communicative exchanges in a longitudinal cohort of seventeen-year-olds followed since infancy, testing their ability to moderate stereotype tendencies toward children as contrary evidence accumulates. Our results reveal that the impact of stereotypes on communicative behavior is linked to individual variation in the right anterior cingulate gyrus. In contrast, the ability to moderate stereotype tendencies is influenced by early-life exposure to social interactions, beyond the effects of familial environment and social experiences acquired later in life. These findings pinpoint a key brain structure underlying stereotype tendencies and suggest that early-life social experiences have lasting consequences on how individuals integrate factual evidence during interpersonal communication.
