The Halo and Horn Effects

We have a tendency to adapt information that conflicts with our earlier impressions in order to make it fit within the frame we have established. This is known as selective distortion, and it manifests in the halo and horn effects. The angelic halo and devilish horn are useful metaphors for the lasting effects of positive and negative impressions.

The halo effect occurs when initial positive perceptions lead us to view later interactions as positive. The horn effect occurs when initial negative perceptions lead us to view later interactions as negative. Owen Hargie, Skilled Interpersonal Interaction: Research, Theory, and Practice (London: Routledge, 2011), 281. Since impressions are especially important when a person is navigating the job market, let’s imagine how the horn and halo effects could play out for a recent college graduate looking to land her first real job. Nell has recently graduated with her degree in communication studies and is looking to start her career as a corporate trainer. If one of Nell’s professors has a relationship with an executive at an area business, his positive verbal recommendation will likely result in a halo effect for Nell. Since the executive thinks highly of his friend the professor, and the professor things highly of Nell, then the executive will start his interaction with Nell with a positive impression and interpret her behaviors more positively than he would otherwise. The halo effect initiated by the professor’s recommendation may even lead the executive to dismiss or overlook some negative behaviors. Let’s say Nell doesn’t have a third party to help make a connection and arrives late for her interview. That negative impression may create a horn effect that carries through the interview. Even if Nell presents as competent and friendly, the negative first impression could lead the executive to minimize or ignore those positive characteristics, and the company may not hire her.
