Which term refers to a strong belief held without considering all available information?

The term that best describes a strong belief held without considering all available information is prejudice. Prejudice refers to formed opinions that are often based on stereotypes or unfounded assumptions about an individual or group, rather than objective facts or thorough analysis. It involves a preconceived judgment—an emotional bias toward or against something or someone—often rooted in cultural or societal influences that can cloud rational thought.

While bias can also refer to an inclination toward a particular perspective, it does not inherently convey the emotional weight or the lack of comprehensive consideration implied by prejudice. Similarly, judgment often involves critical thinking and the evaluation of information to reach a conclusion, suggesting a more informed decision-making process. Opinion, on the other hand, implies a personal belief but does not necessarily carry the connotation of being held stubbornly without evidence or reasoning. Thus, prejudice captures the essence of holding strong beliefs without a well-rounded understanding of the situation.
