Comey quoted “Everyone’s a Little Bit Racist,” a song from the Broadway hit “Avenue Q.” Social science research generally finds the musical – and Comey – is right. The Kirwan Institute for the Study of Race and Ethnicity at Ohio State University publishes an annual “Implicit Bias Review” that collects research on unconscious racial bias. In one study, research subjects playing a police video game were more likely to accidentally “shoot” unarmed black characters than white ones. In a similar study, pediatricians were more likely to prescribe painkillers to white patients than black ones. But the 2013 report also finds that training can help to counter unconscious bias.
