So don’t call attention to racial and ethnic differences; make them less relevant by ramping up similarity and celebrating the group’s shared values and common identity.49 A great deal of research in social psychology shows that people are warmer and more trusting toward people who look like them, dress like them, talk like them, or even just share their first name or birthday.50 There’s nothing special about race. You can make people care less about race by drowning race differences in a sea of similarities, shared goals, and mutual interdependencies.51
