In a study including 3,570 black Americans and 891 non-Hispanic white Americans, participants were asked to assess the presence of counting, arranging, repeating words, and washing and checking behaviors. Participants were also asked to answer a 10 item list gauging the presence of everyday discrimination, and then asked the primary reason why they believed they were discriminated against in that way: race, gender, age, weight, height, income, sexual orientation, etc.
