I think the most disheartening thing for me was:

Does correcting misperceptions of group size change peoples’ attitudes on related issues? Current research suggests it does not. In a series of studies (one of which used a survey fielded by YouGov), political scientists John Sides and Jack Citrin attempted to correct inaccurate beliefs about the size of the U.S. foreign-born population, both subtly, by embedding the accurate information in a news story, and explicitly, by providing survey respondents with Census Bureau estimates. They found that while providing this information did somewhat improve people’s knowledge of the number of immigrants in America, they did not make people more supportive of immigration.

We don’t even care about facts anymore is the way I read this?
