Abstract
This paper provides representative evidence on people's beliefs about the extent of racial discrimination in the United States and to what extent these beliefs drive support for affirmative action policies. We report evidence from two separate experiments. In the first experiment, we elicit incentivized beliefs about how likely resumes with black-sounding names are to receive a callback for an interview relative to resumes with white-sounding names. We then provide a random subset of our respondents with the true statistic and investigate how this affects support for affirmative action policies. To deal with experimenter demand effects, we perform a second experiment where the key outcome questions are only asked one week later in an obfuscated follow-up study.
