Overcoming unconscious bias in recruitment.

Updated: Oct 23, 2023

Unconscious bias is a term used to describe the unintentional biases and preferences that influence our decisions and actions. When it comes to recruiting, unconscious bias can have a significant impact on the hiring decisions.


Unconscious bias can manifest in many different ways during the recruitment process. For example, a manager may be more likely to hire a candidate who shares their background or interests, or they may unconsciously favour candidates who are similar to themselves in terms of gender, age, race, or ethnicity. These biases can lead to a lack of diversity in the workplace, as well as missed opportunities to hire highly qualified candidates.


One of the most common forms of unconscious bias in recruitment is affinity bias, which refers to the tendency to favour candidates who are similar to ourselves. For example, a male manager may be more likely to hire a male candidate for a technical role, even if a female candidate is equally qualified.


Another common form of unconscious bias is confirmation bias, which refers to the tendency to seek out information that confirms our existing beliefs and ignore information that contradicts them. This can lead to managers unconsciously favouring candidates who confirm their preconceived notions about what a successful candidate looks like. For example, a manager may favour candidates who have attended a prestigious university, even if this is not a key requirement for the role.


Unconscious bias can also manifest in the form of halo and horn effects. The halo effect refers to the tendency to attribute positive qualities to someone based on a single positive trait or characteristic. For example, a manager may assume that a candidate who went to a top school is also highly skilled, without considering other factors such as relevant experience or job fit. The horn effect refers to the opposite tendency, where a single negative trait or characteristic is used to form an overall negative impression of the candidate.


To combat unconscious bias in recruitment, managers must first become aware of their own biases and how they may be influencing their decisions. This can be achieved through training and education on unconscious bias and diversity and inclusion. Managers can also take steps to reduce the impact of unconscious bias, such as using structured interview processes, blind resume reviews, and diverse interview panels.


Structured interview processes involve asking all candidates the same set of questions in the same order, which helps to reduce the impact of personal biases. Blind resume reviews involve removing identifying information such as name, gender, and age from resumes before they are reviewed, which helps to reduce the impact of affinity bias. Diverse interview panels involve including people from diverse backgrounds and perspectives in the hiring process, which helps to reduce the impact of confirmation bias.


In conclusion, unconscious bias can have a significant impact on the recruitment decisions of managers. Affinity bias, confirmation bias, halo and horn effects are all common forms of unconscious bias that can lead to a lack of diversity in the workplace and missed opportunities to hire highly qualified candidates. To combat unconscious bias, managers must become aware of their own biases and take steps to reduce their impact, such as using structured interview processes, blind resume reviews, and diverse interview panels. By doing so, managers can create a more inclusive and diverse workplace that benefits everyone.
