Definition
Cognitive biases are unconscious mental shortcuts that influence our judgments and decisions. In recruitment, they lead us to favour certain candidates for wrong reasons (appearance, similarity to us, first impression) rather than their actual competencies. Even experienced recruiters are systematically influenced by these biases.
The Six Main Biases in Recruitment
Most Common Cognitive Biases
| Bias | Description | Concrete Example | Counter-measure |
|---|---|---|---|
| Confirmation bias | Seek to validate first impression | Ask questions to confirm positive initial view | Standardised evaluation grid |
| Halo effect | One quality masks defects | Top university → overestimate all competencies | Evaluate competency by competency |
| Similarity bias | Prefer candidates who resemble us | Same university, same interests = more confidence | Involve a different second interviewer |
| Anchoring bias | Focus on first information | First candidate becomes involuntary reference | Evaluate after all interviews |
| Availability bias | Overvalue recent or striking information | Striking anecdote masks average competencies | Immediate factual notes |
| Contrast effect | Comparison between candidates distorts judgment | After 3 poor profiles, mediocre 4th seems good | Pre-defined absolute criteria |
How to Limit Biases in Your Process
- 1
Standardise Interviews
Ask the same questions to all candidates, in the same order. No improvisation.
- 2
Use Evaluation Grids
Objective criteria defined in advance, scoring for each competency before deciding.
- 3
Anonymise CVs (Initial Screening)
Mask name, photo, address, age to focus on competencies and experience.
- 4
Make Collective Decisions
Cross-reference multiple views to dilute individual biases. Minimum 2 evaluators.
- 5
Measure Objectively
Assessments and practical tests to evaluate concretely rather than relying on impressions.
- 6
Step Back
Never decide immediately. Let 24 hours pass before confirming your choice.
Practical Anti-bias Tip
After each interview, ask yourself: 'What do I like about this candidate? Is it related to the role or personal criteria (likeability, similar background to mine)?' This simple question helps you become aware of your biases.
Does having cognitive biases mean being discriminatory?
No, having cognitive biases is normal and universal. Our brains function this way to process information quickly. The difference with discrimination is awareness and action: recognising your biases and implementing processes to limit them. Conscious discrimination is illegal; unconscious biases are human.
Do experienced recruiters have fewer biases?
Contrary to intuition, no. Experience can even reinforce certain biases (overconfidence in intuition, entrenched habits). Research shows experience alone isn't sufficient to reduce biases. The best recruiters structure their processes.
Is 100% objective recruitment possible?
No, nor should it be. Human judgment and feelings have their place, especially for assessing cultural fit. The goal is to limit biases on objective criteria (competencies, experience) and preserve informed subjectivity on human criteria (motivation, values).
How can I measure bias impact in my organisation?
Analyse your last 12 months of hires: what is the diversity of profiles recruited? Do all hires resemble the recruiter's profile? What is your trial period failure rate? A high rate can reveal biases. Compare whether evaluations are based on observable facts or impressions.
