Horn Effect

The horn effect is a cognitive bias that can have far-reaching consequences, particularly in domains like hiring and performance evaluations. This bias stems from a tendency to allow a single negative trait or behavior to create an overall impression of a person, which can result in unfair judgments regarding promotions, relationships, and more.

What Is Horn Effect?

The horn effect refers to an individual’s overall perception of someone or something which is negatively influenced [mfn] Burton, S., Cook, L. A., Howlett, E., & Newman, C. L. (2014). Broken halos and shattered horns: overcoming the biasing effects of prior expectations through objective information disclosure. Journal of the Academy of Marketing Science, 43(2), 240–256. https://doi.org/10.1007/s11747-014-0378-5 [/mfn] by a single negative behavior or action, resulting in a tendency to view people as generally incompetent or untrustworthy, despite the presence of positive qualities or behaviors. It is also known as the reverse halo effect.

The halo and horn effect are opposite biases that can impact an individual’s judgments of people. The halo effect [mfn] Gabrieli, G., Lee, A., Setoh, P., & Esposito, G. (2021). An Analysis of the Generalizability and Stability of the Halo Effect During the COVID-19 Pandemic Outbreak. Frontiers in psychology, 12, 631871. https://doi.org/10.3389/fpsyg.2021.631871 [/mfn] occurs when people have an overall positive impression of someone, which can lead individuals to see their traits or actions in a positive light, even if there is no evidence to support those perceptions.

In contrast, the horn effect occurs when people have an overall negative impression [mfn] Senft, N., Hamel, L. M., Penner, L. A., Harper, F. W. K., Albrecht, T. L., Foster, T., & Eggly, S. (2018). The influence of affective behavior on impression formation in interactions between black cancer patients and their oncologists. Social science & medicine (1982), 211, 243–250. https://doi.org/10.1016/j.socscimed.2018.06.022 [/mfn] of someone, ultimately, which affects not only an individual’s professional life but also their personal well-being.
