Skin switching, implicit racial bias and moral enhancement

A recent study has shown that a person’s implicit racial bias can be reduced if she spends some time experiencing her body as dark-skinned. Psychologists in Spain used an immersive virtual reality technique to allow participants to ‘see’ themselves with a different skin colour. They measured the participants’ implicit racial bias before and after the intervention, finding that the embodiment of light-skinned individuals in a dark-skinned virtual body at least temporarily reduced their implicit bias against people who are coded as ‘out-group’ on the basis of skin colour.

Implicit racial bias is an evolved, unconscious tendency to feel more positively towards members of one’s own race (one’s ‘in-group’) than towards members of a different race (members of an ‘out-group’). The bias can be (and was in this study) measured using a version of the implicit association test, which requires participants to quickly catagorise faces (black or white) and words (positive or negative) into groups. Implicit bias is calculated from the differences in speed and accuracy between categorising (white faces, positive words) and (black faces, negative words) compared to (black faces, positive words) and (white faces, negative words). Crucially, implicit racial bias has been shown to be uncorrelated with explicit racial bias – self-reports of negative racial stereotypes. This means that even those who are not consciously averse to people from other racial groups often demonstrate a deep-seated bias against them as an evolutionary hangover. Hearteningly, the authors of the study started from the idea that encoding people by race may be a reversible by-product of human evolution used to detect coalitional alliances. What their study confirmed is that immersive virtual reality provides a powerful tool for placing people into a different race ‘coalition’ by changing their body representation and consequently reducing their implicit aversion to the racial characteristics there represented.
