HaloEffekt

HaloEffekt, commonly rendered as Halo-Effekt in German-language literature, refers to a cognitive bias in which a positive impression of a person, object, or brand in one aspect unduly influences judgments about other attributes. It is widely discussed in psychology, marketing, and organizational studies and can affect evaluations in both social and consumer contexts.

Origin and concept: The halo effect was first described by psychologist Edward Thorndike in 1920 based on studies of military officer ratings. He observed that ratings on various traits tended to rise and fall together, suggesting that an overall favorable impression could color judgments of unrelated characteristics. The term evokes a halo surrounding a person that biases perception and decision making.

Examples and applications: In personnel decisions, a candidate who is perceived as attractive or confident may be rated as more competent or intelligent, regardless of objective evidence. In marketing and branding, a strong first impression of a brand or product can lead consumers to judge other features—such as quality or reliability—more positively. Marketers sometimes deliberately cultivate a halo by aligning product design, packaging, and endorsements to create a cohesive, favorable image.

Measurement and limitations: The halo effect is studied through controlled experiments, rating tasks, and field observations. Results vary with context, task difficulty, and individual differences. Critics note that halo effects can distort objectivity, leading to biased judgments. Mitigation strategies include using standardized criteria, blinding evaluators to irrelevant information, employing multiple raters, and separating initial impressions from evaluative judgments.
