What is the halo effect?

The halo effect refers to a cognitive bias in which the perception of one positive trait significantly influences the overall evaluation of an individual. For instance, if someone is perceived as attractive, they may also be judged as more intelligent, friendly, or capable, even if no evidence supports these assessments. This effect underscores how our perceptions are interlinked and how an admired characteristic can overshadow a more balanced judgment.

In contrast, the other options do not accurately capture the essence of the halo effect. The influence of a negative trait pertains more to a different bias and does not address the enhancement of positive traits. Evaluating traits solely based on factual achievements suggests a more objective assessment, which contradicts the subjective nature of the halo effect. Lastly, overlooking flaws in close relationships, while related to personal biases, focuses more on interpersonal dynamics rather than the broader, single-trait influence characteristic of the halo effect.
