Study Finds Virtual Body Swapping Could Reduce Prejudice

Tiny, pale infant fingers grasp the finger of an adult with dark skinThe old adage recommending against judging a person until you’ve walked a mile in his or her shoes may be entirely true, according to a new study. It’s common to make snap judgments about others, and often these stereotypes are based on group membership. Adults, for instance, may stereotype children as unruly or unintelligent, and racist stereotypes remain depressingly common. A new study published in Trends in Cognitive Sciences suggests that it may be possible to undermine these biases and stereotypes via virtual body swapping.

Swapping Bodies to Eliminate Implicit Bias

Many prejudicial beliefs are unconscious, as demonstrated by various implicit associaton tests. These tests show that people are more likely to pair images of members of minority groups with negative words and phrases, even when the test-taker claims to have no conscious prejudicial thoughts. There’s been little research into whether and how these implicit ideas can be changed, but Manos Tsakiris of the Royal Holloway University of London and Mel Slater, a professor at the University of Barcelona and University College London, believe that virtual reality could help dismantle subtle biases.

The team used virtual reality machines to cause white people to feel like their bodies were black. The approach relies in part on a well-known illusion called the rubber hand illusion. Through this illusion, white participants watch as a dark-skinned rubber hand moves in synchrony with their own hand at the same time that the participant’s view of his or her hand is obscured. This “tricks” the brain into perceiving the black hand as its own, inducing a sense of ownership over a previously unfamiliar body.

Researchers found that white participants who were made to feel like they had black bodies experienced a reduction in biased and racist thoughts. As part of the study, researchers also induced adults to relate to children’s bodies. Unsurprisingly, those adults reported feeling more childlike. The study’s authors caution that there’s no simple cure for prejudice. However, by encouraging people to put themselves into another’s shoes, prejudice could steadily melt away.

    While I find this to be quite fascinating, I don’t necessarily think that it is that practical.

    It is literally a chance to step into someone else’s shoes. I love it and think that this is a fabulous idea!!

    Sometimes we just need to take a little more time to think about how others would feel if we were treating them in such a horrible way and how we would feel if we had to endure that same sort of prejudice against us. know that this is probably very simplistic, but sometimes all it takes is to step back for a moment and imagine what they are feeling and this can clear you of any old prejudices that you could feel.

    I really do wish that it could be this easy to reduce prejudice in our society. My fear is that for many people this is prejudice that has resided with them for years and years, and it takes so much and so many experiences to alleviate this kind of hatred and misunderstanding. I don’t know what the answer is, because it is almost as if you solve one problem then there are a hundred other problems to take their place.
