Dr. Linda Tropp was quoted in an article, 'Tolerance over race can spread, studies find', The New York Times, October 2008. She speaks about the so-called "extended-contact effect".
This was supposed to be the election when hidden racism would rear its head. There was much talk of a "Bradley effect," in which white voters would say one thing to pollsters and do another in the privacy of the booth; of a backlash in which the working-class whites whom Senator Barack Obama had labeled "bitter" would take their bitterness out on him.
But lost in all that anguished commentary, experts say, was an important recent finding from the study of prejudice: that mutual trust between members of different races can catch on just as quickly, and spread just as fast, as suspicion.
In some new studies, psychologists have been able to establish a close relationship between diverse pairs — black and white, Latino and Asian, black and Latino — in a matter of hours. That relationship immediately reduces conscious and unconscious bias in both people, and also significantly reduces prejudice toward the other group in each individual's close friends.
