Which of the following practices helps prevent prejudice in evaluation?

Impartiality is central to preventing prejudice in evaluation because it ensures that judgments are made based on objective criteria rather than subjective opinions or biases. When evaluators maintain an impartial stance, they focus on the facts, data, and evidence related to the performance or behavior being assessed, rather than being influenced by personal feelings, stereotypes, or preconceived notions about an individual or group. This practice fosters fairness and equity in the evaluation process, leading to more accurate and just outcomes.

In contrast, the other options might not effectively mitigate prejudice. Decisiveness, while important for timely decision-making, does not directly address bias. Authority may introduce power dynamics that can influence evaluations, potentially leading to unfair practices. Hierarchy can establish a system where those lower in rank may feel pressured to conform to the views of those above them, which could reinforce biases rather than mitigate them. Thus, a commitment to impartiality is essential for achieving unbiased evaluations.
