What is the horns effect?
It makes you create a very negative judgment about a candidate just because one specific characteristic stood out negatively. This one characteristic leads to you not being critical anymore about other characteristics. It is the exact opposite of the Halo effect.
Example in the hiring process.
When we read on a candidate’s resume that the candidate grew up in a criminal area of a specific city, for example, we can decide to dismiss the candidate because of that, without focusing on what’s actually relevant. The Horns Effect can also arise when the interviewer finds the candidate unattractive.
