Perception that other races look alike rooted in visual process, says study

Research says brain 'de-individuates' other groups, while scientists say findings could help tackle racial bias

The common perception that people from other racial groups look alike is rooted in the way human brains process what they see, researchers say.

It has long been known that people find it easier to tell apart members of their own race than those of a different race. But the mechanism behind this has been the topic of much research.
