First the good news: "...56 percent (of respondents) said they know someone with an intellectual disability. That connection appeared to be directly correlated with how comfortable individuals were with the idea of their children being in class with, dating or marring a person with an intellectual disability as well as their own ideas about employing or working with individuals with special needs."
Respondents who knew someone with ID were much more open with these attitudes toward integration. Presumably, the negative stereotypes of ID are vanquished with interpersonal contact.
But, especially in the absence of familiarity, biases are observed. For example, while most people thought persons with ID should be employed, 20% indicated that they would not be comfortable hiring such individuals. And, 39 percent of respondents said that kids with ID should not be educated in classrooms with other children their own age. These findings reflect both implicit and explicit biases in our ableist society.
On a hopeful and just note, consistent with other surveys, the millennial demographic seems to be the most progressive-especially women: "More than 60 percent of young women said they would be okay with their child marrying or dating a person with intellectual disabilities".
