You’re watching a video of a needle piercing an anonymous hand, sinking slowly into the web between the thumb and index finger. You wince as you imagine the pain that the other person must feel, and for good reason. As you watch, you nervous system essentially duplicates the experience, responding as if you were vicariously feeling the pain yourself. This is typical of what happens when people see others in pain, but Italian scientist Alessio Avenanti has found an important exception to the rule. Racial bias can negate this ability to feel the pain of someone from a different ethnic group.
