Bias refers to a tendency to favor one perspective or group over another, often leading to unfair judgments or decisions. For example, if a teacher consistently gives higher grades to students who share similar interests, they may be exhibiting bias. This can affect the learning environment and the opportunities available to all students. Bias can also manifest in media coverage, where certain stories or viewpoints are highlighted while others are ignored. For instance, if a news outlet focuses primarily on negative events in a specific community, it may create a skewed perception of that community. Recognizing and addressing bias is essential for promoting fairness and understanding in society.
