School-age kids may be biased against their peers who are overweight or obese and not even know it, a new study finds.
To measure levels of bias in schoolchildren, researchers showed them a series of photos of children who were slim and children who were overweight. They found that the kids showed more bias toward the overweight kids than the slimmer ones, according to the study.
It’s unclear exactly where this type of bias stems from, but previous research on racial bias has suggested that unconscious biases are not innate, said study co-author Dr. Eliana Perrin, a professor of pediatrics at the University of North Carolina at Chapel Hill. In other words, these biases must be learned.
