You're better at telling faces apart from your own race than others

Across more than a hundred studies, people consistently recognise faces from their own race more accurately than faces from other races, mistaking cross-race strangers for each other far more often. A large meta-analysis confirmed the effect appears worldwide regardless of which race counts as 'own', and it has contributed to real wrongful eyewitness identifications in court.
