How to Avoid Unconscious Bias in Recruitment and Interviewing

Recruitment and interviewing are the cornerstones of building a talented and diverse workforce. However, beneath the surface of these processes lurk unconscious biases that can significantly impact hiring decisions. These biases often stem from deeply ingrained societal stereotypes and personal perceptions. In this in-depth blog, we will thoroughly examine 14 common unconscious biases encountered in recruiting and interviewing. For each bias, we will provide real-world examples that dive deep into the intricacies of how these biases manifest and offer concrete strategies to mitigate their effects.

Confirmation Bias

Confirmation bias is the tendency to process information in a way that reinforces preexisting beliefs or assumptions about a person. Let’s say a hiring manager is reviewing resumes for an open position. One candidate attended the same college as the hiring manager, which happens to be their alma mater. The manager subconsciously assumes that the candidate is a good fit based on the shared educational background. As a result, they focus on the candidate’s positive attributes while downplaying potential shortcomings, effectively confirming their bias that graduates from their college are more desirable candidates.

To avoid this, encourage hiring managers to remain aware of their biases and adopt a systematic evaluation process that considers all candidates impartially based on their qualifications and experiences.

Halo Effect Bias

The halo effect bias occurs when a single positive trait or impression of a candidate overshadows other qualities, leading to biased assessments. During an interview, a candidate displays exceptional communication skills, answering questions confidently and articulately. This positive first impression creates a “halo” effect, causing the interviewer to overlook the candidate’s limited experience in the required technical skills for the role. Despite the lack of technical proficiency, the candidate is given a higher rating because of the initial positive impression.

Try to train interviewers to evaluate candidates holistically, considering all relevant qualifications, rather than being unduly influenced by a single positive aspect.

Horn Effect Bias

Horn effect bias occurs when a single negative aspect or impression of a candidate dominates the overall evaluation, resulting in an unfairly negative assessment. For example, a candidate arrives slightly late for an interview due to unexpected traffic congestion. The hiring manager becomes visibly annoyed by this delay and unconsciously carries that irritation throughout the interview. As a result, the manager forms a negative impression of the candidate’s professionalism and qualifications, even if the late arrival was a one-time occurrence.

Encourage interviewers to address specific issues or concerns rather than allowing a single negative impression to taint their overall assessment of the candidate.

Expectation Bias

Expectation bias arises when preconceived expectations about a candidate influence the interpretation of their performance. Say a hiring manager receives a resume from a candidate with a prestigious university degree and a history of working at renowned companies. The manager expects the candidate to perform exceptionally well in the interview. Consequently, the manager subconsciously interprets the candidate’s responses more favorably, attributing their performance to the initial high expectations rather than objective evaluation.

To avoid this, emphasize the importance of evaluating candidates based on their performance and qualifications for the specific role, rather than letting expectations unduly influence assessments.

Affect Bias

Affect bias occurs when emotions, either positive or negative, drive hiring decisions, leading to subjective and potentially biased judgments. For example, a candidate reminds the hiring manager of a former colleague with whom they had a strained working relationship. Despite the candidate’s qualifications, the manager unconsciously associates the negative emotions from the past relationship with the candidate and makes an unfairly negative hiring decision.

Focus on promoting emotional intelligence among hiring managers, helping them recognize and mitigate the influence of emotions on their decision-making.

Similarity Bias

Similarity bias involves favoring candidates who share a perceived connection or similarity with the interviewer, such as shared interests or backgrounds.

Real-World Example: An interviewer discovers that a candidate shares their passion for a particular hobby. The interview veers off-topic as the interviewer enthusiastically discusses this shared interest, inadvertently allowing the candidate’s qualifications to take a back seat. The candidate is rated more favorably due to this personal connection, even though the shared hobby has no relevance to the job.

Train interviewers to prioritize qualifications and competencies relevant to the job, ensuring that assessments are grounded in objective criteria rather than non-job-related similarities.

Overconfidence Bias

Overconfidence bias is the belief in one’s ability to choose the right candidate without considering diverse perspectives, leading to biased decision-making. Let’s say a hiring manager with extensive experience in a particular field is confident in their ability to identify top talent. They dismiss input from other team members and rely solely on their judgment to select a candidate. This overconfidence prevents the team from making a well-rounded decision and could lead to a suboptimal hire.

Be sure to implement a collaborative hiring process that incorporates multiple perspectives, promoting diversity of thought and reducing the risk of overconfidence affecting the outcome.

Affinity Bias

Affinity bias occurs when interviewers prefer candidates with whom they share commonalities or who make them feel comfortable, irrespective of qualifications. For example, a hiring manager finds out that a candidate shares their love for a specific sports team. This common interest creates a sense of affinity, and the manager unconsciously favors the candidate throughout the interview process, even though other candidates have superior qualifications.

Instead, promote diversity and inclusion in the hiring process, emphasizing that decisions should be based on objective criteria rather than personal connections or affinities.

Beauty Bias

Beauty bias involves favoring candidates who possess physical attractiveness, leading to the perception that they are more qualified for a role.

During a video interview, a candidate who adheres to conventional standards of physical beauty is given higher ratings than another candidate with equivalent qualifications but who doesn’t conform to these standards. The subconscious bias towards physical appearance skews the assessment in favor of the more conventionally attractive candidate.

Implement blind recruitment processes when feasible, placing emphasis on qualifications and competencies rather than physical appearance.

Conformity Bias

Conformity bias arises when peer pressure or group dynamics influence hiring decisions, resulting in choices that align with the group’s consensus. Groupthink contributes significantly to this bias, because it occurs when individuals conform to a collective decision, even if they have reservations, just to maintain group harmony and avoid conflict.

Real-World Example: Interviewers in a group setting begin to conform to the opinions of their colleagues, even when they have doubts about a candidate’s qualifications. They hesitate to voice their concerns to avoid disrupting the group’s cohesion.

Avoidance Strategy: Foster an open and diverse discussion during the hiring process, actively encouraging dissenting opinions and independent assessments to prevent groupthink and train interviewers to conduct independent assessments and decisions, providing guidance on recognizing and mitigating conformity bias.

Intuition Bias

Intuition bias involves relying on one’s gut feeling or instinct to make hiring decisions, often without concrete evidence or objective evaluation. For example, a hiring manager relies on their intuition to judge a candidate, bypassing a thorough assessment of qualifications. Despite a lack of data or evidence supporting the decision, the manager hires the candidate based on their gut feeling.

Be sure to emphasize the importance of evidence-based decision-making and introduce structured interview processes that prioritize data and job-related criteria over intuition.

Contrast Bias

Contrast bias manifests when interviewers compare candidates to their predecessors, rather than evaluating each candidate independently, leading to biased judgments.

Real-World Example: A strong candidate follows a weak candidate in the interview schedule. The contrast between the two candidates makes the strong candidate appear even more impressive by comparison, leading interviewers to rate them more favorably than they would have in isolation.

Avoidance Strategy: Train interviewers to evaluate candidates based on their own merits, divorced from comparisons to others, and employ consistent evaluation criteria.

Implicit Bias

Implicit bias refers to the subconscious stereotypes or negative attitudes that unconsciously affect decision-making, often without the individual’s awareness. Many hiring managers unconsciously favors candidates who share their ethnicity, even if it is unrelated to the job. This bias affects their decision-making without them realizing it.

Instead, offer training and awareness programs to help interviewers recognize and address their implicit biases. Implement blind recruitment processes to minimize opportunities for bias to creep into assessments.

Unconscious biases run deep in the recruitment and interviewing processes, undermining the quest for fair and objective hiring. To build diverse, inclusive, and high-performing teams, organizations must confront and mitigate these biases at their core. By providing awareness, comprehensive training, and instituting structured and objective evaluation procedures, companies can establish a hiring environment that genuinely values merit over personal biases. In doing so, organizations not only bolster their own success but also contribute to the broader mission of creating a just and equitable society.
