Data and Code for: ``Revealing Stereotypes: Evidence from Immigrants in Schools"

We study how people change their behavior after being made aware of bias. Teachers in Italian
schools give lower grades to immigrant students relative to natives of comparable ability. In two
experiments, we reveal to teachers their own stereotypes, measured by an Implicit Association
Test (IAT). In the first, we find that learning one’s IAT before assigning grades reduces the
native-immigrant grade gap. In the second, IAT disclosure and generic debiasing have similar
average effects, but there is heterogeneity: teachers with stronger negative stereotypes do not
respond to generic debiasing, but change their behavior when informed about their own IAT
