Impacts of Knowledge and Familiarity on Differences in Explicit Stigma and Implicit Biases Toward Autism Across France

Autistic people frequently experience stigma that can be expressed whether consciously or unconsciously. This study examined how familiarity with autistic people, factual knowledge about autism, sociodemographic characteristics, and cultural value orientations relate to three facets of autism stigma: desired social distance, stereotypical beliefs, and implicit bias. French adults (N = 277) completed online measures of autism knowledge, familiarity, social distance, and stereotypes, a cultural orientation scale, and an Implicit Association Test assessing automatic evaluations of autism. Results showed that familiarity and knowledge about autism were both associated with lower explicit stigma, while only familiarity was linked to a reduction in implicit prejudice. Moreover, the regression analysis has shown that the different constructs of stigma evaluated in our study (social distance, stereotype, and implicit bias) were predicted by different variables. Particularly, social distance was predicted by stronger stereotypes, male gender, and more individualistic values, whereas stereotypes were higher among older, less-educated participants with limited knowledge, less familiarity, and greater social distance. Implicit bias was higher among men, participants endorsing vertical collectivism, and those with lower levels of intimate familiarity. These results were discussed within the framework of multidimensional approaches to assessing and reducing stigmatization in a French sociocultural context.
