Being in a romantic relationship with a partner who is friends with people from different racial and ethnic groups may help avoid prejudice.

Research participants spent time answering and asking questions that increased the level of self-disclosure over time. The conversations began with lower-level information and then escalated to more personal information.
"Our research found that there were more positive attitudes towards answering questions when there were intergroup couples interacting versus same-group couples or individuals," said Keith Welker, Ph.D., a Wayne State graduate and lead author of the study. "Our findings suggest that interacting in an intergroup context with the presence of your romantic partner is something that can improve your attitude toward other groups significantly rather than just interacting alone. This is because romantic partners can alleviate threats, help improve conversations and create something you have in common with other couples."
