Psychologists have traditionally studied explicit attitudes and beliefs about social groups (age, gender, race/ethnicity, sexuality, disability, body weight etc.) by simply asking people about them. Repeated surveys have uncovered that our stated attitudes and beliefs about outgroups (people different from us) have been changing toward more neutral, unbiased, responses.

In other words, we are witnessing a clear drop off in reported prejudices, at least in the United States.

But what about our implicit attitudes and stereotypes? These less conscious, more automatic attitudes and beliefs can’t be measured using survey questions. Instead, psychologists use tools like the Implicit Association Test to see if and how our implicit biases are changing.
