Could virtual body swapping help end racism?

London: Researchers have found that virtual body swapping can cause people to change their attitudes about others and reduce biases, a discovery that provides insight on how to approach racism and gender discrimination.

In virtual body swapping experiments, researchers used the brain's ability to bring together information from different senses to make white people feel that they were inhabiting black bodies and adults feel like they had children's bodies. The results of such experiments are remarkable and have important implications for approaching phenomena such as race and gender discrimination, researchers said.

Professor Manos Tsakiris of the Royal Holloway University of London and Professor Mel Slater of University College London and the University of Barcelona have developed ways to expose participants to bodily illusions that induce ownership over a body different from their own with respect to race, age, or gender. For white people who were made to feel that they had black bodies, their unconscious biases against black people diminished, researchers found.

Adults who felt as if they had children's bodies processed perceptual information and aspects of themselves as being more childlike. "Our findings are important as they motivate a new research area into how self-identity is constructed and how the boundaries between 'ingroups' and 'outgroups' might be altered," said Tsakiris.

"More importantly though, from a societal point of view, our methods and findings might help us understand how to approach phenomena such as racism, religious hatred, and gender inequality discrimination, since the methods offer the opportunity for people to experience the world from the perspective of someone different from themselves," said Tsakiris.

While there is no simple "cure" for racism or other biases, "the research shows that integration of different sensory signals can allow the brain to update its model of the body and cause people to change their attitudes about others," said Slater.

The research was published in the Cell Press journal Trends in Cognitive Sciences.
