New research suggests prejudices may form at a much earlier age, but it also offers hope that biases can be unlearned
When Harvard’s Mahzarin Banaji began studying children’s brains two decades ago, in search of the roots of racism, she quickly concluded that bias is a learned behavior and learned over time - perhaps spread over the course of childhood. All that’s changed. Banaji’s recent research suggests that children’s brains process and accept bias much faster than previously believed - in just hours or days, rather than months or years. This revelation makes it even more important that adults not expose kids to bias.
