The contact hypothesis has been intensively studied. A recent review identifies twenty-seven randomized controlled trials (RCTs) investigating Allport’s idea. Overall, these studies find that contact reduces prejudice, although the review calls attention to the importance of the nature of the contact. If this is right, schools and universities are obviously key. They bring together young people from different backgrounds in a single location, at an age when everyone is much more plastic. In one large US university, where roommates were assigned at random, a study found that white students who happened to end up with African American roommates were significantly more likely to endorse affirmative action, and that white students assigned roommates from any minority group were more likely to continue to interact socially with members of other ethnic groups after their first year, when they had full freedom in choosing whom to associate with.This process of socialization could start even earlier. A policy change in Delhi demonstrated the power of bringing together young children from very different backgrounds. Starting in 2007, elite private schools in Delhi were required to offer places to poor students. In an ingenious study on the impact of this policy change, randomly chosen children were given the responsibility to select teammates for a relay race.Some of them attended schools that had already admitted poor children, and some attended schools that had not done so yet. And, within schools, some children were in study groups with poorer children (based on the first letter of their first name), and some were not. To help them decide who they wanted to partner with in the race, they were all given a chance to observe everyone else run a test race. There was, however, a catch. They had to agree to have a playdate with whomever they picked for their team. The study found that those students from affluent families who had not been exposed to poor students in their school avoided picking them, even when they were better runners, to avoid having to spend time with them. But those who’d had some exposure to children from less-well-off families in their schools, thanks to the new policy, were much more likely to pick the best runner even if the child was from a poor family, because the prospect of a playdate was no longer all that daunting. And those who were in a study group with poor children were even more likely to invite poor child to run and play with them. Familiarity performed its magic.
The “Contact Hypothesis”. How contact with people of different social groups can actually help reduce prejudice. This excerpt talks about 1 innovative study done in India, and there has been evidence to support this hypothesis with 27 other RCTs (Randomized Controlled Trials) done.
