Some biases are positive and helpful—like choosing to only eat foods that are considered healthy or staying away from someone who has knowingly caused harm. But biases are often based on stereotypes, rather than actual knowledge of an individual or circumstance. Whether positive or negative, such cognitive shortcuts can result in prejudgments that lead to rash decisions or discriminatory practices.| Psychology Today
