in a recent study, psychologists found that a sample of unemployed blue collar workers reported strong anti-minority and anti-immigrant attitudes. the psychologists then had the participants read an article about automation and robotics, which talked about how robots were replacing workers across a wide range of industries. after reading this article, the participants reported more favorable attitudes toward immigrants and minorities. why is this surprising from the perspective of realistic conflict theory? why is this unsurprising from the perspective of cognitive debiasing techniques?
