The halo effect is a cognitive bias in which a person's overall impression of a person, product, or company influences their opinion of specific features or details related to them. For example, a person may have a positive opinion of a company and therefore believe that it has positive attributes, such as good customer service or quality products, when this might not necessarily be the case. This effect can be seen in many areas, including recruitment, marketing, and customer service. To counter the halo effect, companies should strive to provide realistic, balanced and honest information about their products, services and employees. In addition, companies should strive to create an environment in which employees feel safe and empowered to express their opinions and be heard. By taking these steps, companies can ensure that the "halo effect" does not have an undue impact on their customers and employees.
