People of mixed race are considered more attractive than those from a single racial lineage, according to a study. Michael Lewis, a researcher at Cardiff University's School of Psychology, collected a random sample of about 1,200 black, white and mixed-race faces. Each was then rated by a group of observers for their perceived attractiveness, with mixed-race faces coming out top. Dr Lewis said the findings supported those of previous smaller-scale studies. "There was a small but highly significant effect, with mixed-race faces, on average, being perceived as more attractive," he said.
