The halo effect is a cognitive bias that occurs when an individual’s overall impression of a person influences their perception of the person’s specific traits or behaviors. In other words, the halo effect can lead us to perceive someone as being more intelligent, capable, or trustworthy than they actually are, simply because we have a positive overall impression of them.
The halo effect can have a significant impact on our decisions and judgments. For example, we may be more likely to trust someone we perceive as being trustworthy, even if we have no evidence to support this belief. Similarly, we may be more likely to hire someone we perceive as being intelligent, even if they do not have the necessary skills or experience for the job.
