The Halo Effect is a cognitive bias where our overall impression of a person influences how we feel and think about their specific traits. For example, if we perceive someone as friendly, we may also assume they are intelligent or capable, even without evidence to support those beliefs. This effect can occur in various contexts, such as in hiring decisions or performance evaluations. This phenomenon can also extend to brands and products. If consumers have a positive experience with a brand like Apple, they may assume all its products, such as the iPhone or MacBook, are of high quality. The Halo Effect highlights how initial impressions can shape our perceptions in both personal and professional settings.
