Bias is best defined as?

• A. A policy to ensure fairness
• B. An accurate assessment based on evidence
• C. A personal judgement that can be unreasonable or unfounded and lead to another person's unjust (or unethical) treatment.
• D. A formal rule for decision making

Answer: (C)

Bias is a tendency to judge people or situations through a personal lens—colored by stereotypes, emotions, or past experiences—rather than through objective evidence. Because it rests on unverified assumptions, bias can be unreasonable or unfounded and can lead to unfair or unethical treatment of others. That’s why this definition fits best: it centers on a personal judgment that can produce unjust outcomes. The other ideas describe fairness-promoting policies, decisions based on evidence, or formal rules for decision making, which aim to reduce or structure bias rather than define it.
