"Discrimination can also be activated when a person is angered or insulted (Rogers & Prentice-Dunn, 1981)."
"The students initially gave a lower intensity of shock to Black learners than to White ones—reflecting a desire, perhaps, to show that they were not prejudiced. The students then overheard the learner making derogatory comments about them, which, naturally, made them angry. Now, given another opportunity to inflict electric shock, the students who were working with a Black learner administered higher levels of shock than did students who worked with a White learner."
"findings suggest that prejudices often lurk just beneath the surface. It doesn’t take much to activate them, and once activated, they can have tragic conse- quences for how we perceive and treat a particular member of an out-group."
