The document discusses hidden or implicit bias and how it can affect our perceptions and decisions without our awareness. It defines hidden bias as unconscious shortcuts the brain takes to make quick judgments about people and situations. These biases are developed early in life through exposure to various influences and can be expressed through behaviors that are at odds with one's intentions, especially under stress or time pressure. While having implicit biases does not make someone "bad," the document argues it is important to recognize their influence and take steps to counteract them, such as self-examination, establishing fair procedures, and educating oneself and others.
