Bias starts as early as preschool and can be unlearned. According to a study published in the PLOS ONE journal, bias can be unlearned through the process of “reconceptualization.”

Researchers at the University of British Columbia asked 120 children between the ages of three and six to identify pictures of people that were either “nice” or “mean.” Afterward, the children were asked to identify objects that were either “nice” or “mean.”

The results of the study showed that the children who had identified the pictures of people as either “nice” or “mean” were more likely to identify objects as either “nice” or “mean.”

The study’s authors say that the process of “reconceptualization” is key to unlearning bias. The authors say that the process of “reconceptualization” helps kids to see the world from a “neutral perspective.”

The study’s authors say that the process of “reconceptualization” can be taught to children through activities such as role-playing.
