What is the definition of bias or prejudice?

Bias or prejudice refers to a strong belief or opinion that is formed without careful analysis or consideration of all relevant information. This definition highlights the lack of objectivity and the potential for unfair judgment based on incomplete understanding or distorted impressions. In the context of bias, such beliefs can lead to favoritism or discrimination against certain individuals or groups.

The other options do not capture the essence of bias or prejudice. A well-reasoned opinion based on facts indicates a thoughtful and informed stance, which contradicts the notion of bias. An impartial assessment of a person suggests fairness and objectivity, directly opposing the concept of bias. Lastly, a neutral sentiment toward different groups implies a lack of prejudice, as it reflects an absence of strong beliefs or opinions influenced by bias. Therefore, the definition that emphasizes a belief formed without reviewing all information best encapsulates the concept of bias or prejudice.
