In recruitment, fairness and inclusivity are crucial. Adverse impact, or disparate impact, is a key concept for talent acquisition managers and HR professionals to grasp. It refers to potential unintentional bias against certain demographic groups - like race, gender, or age - during the hiring process. This occurs when the selection rate for one group is significantly lower than that of the most favoured group, suggesting the process might be favouring some candidates over others.
How to Measure Adverse Impact
The most common method for measuring adverse impact is the Four-Fifths Rule. According to this rule, adverse impact is likely present if the selection rate for any group is less than 80% of the selection rate for the most favoured group.
Steps to Measure Adverse Impact:
- Identify Groups: Determine the demographic groups involved in your hiring process.
- Calculate Selection Rates: Selection Rate = (Number of selected candidates from a group) / (Number of applicants from that group)
- Compare Selection Rates: Divide each group's selection rate by that of the most highly selected group.
- Determine Adverse Impact: If the ratio for any group is below 80%, adverse impact might be present.
Example: If 20% of male applicants are hired, but only 10% of female applicants, the selection rate for women is 50% of the rate for men (10% / 20% = 0.5, or 50%). Since this is below 80%, this indicates a potential adverse impact.
Importance of Adverse Impact
Understanding adverse impact is vital for several reasons:
- Business Performance: Research suggests that the advantages of diversity amount to more than fairness and feel-good moments. Diversity can also help contribute to smarter teams, which can help drive the success of a business.
- Legal Compliance: Adverse impact can lead to discrimination claims, with legal repercussions under laws like the Equality Act 2010 (in the UK).
- Diversity and Inclusion: Measuring adverse impact helps identify and address biases, leading to a more diverse and inclusive workforce.
- Company Reputation: Commitment to fair hiring practices enhances your organisation’s reputation.
- Employee Morale and Retention: Fair recruitment practices ensure employees feel valued, improving morale and retention.
Improving Adverse Impact: Practical Steps
Once identified, it’s essential to address and mitigate adverse impact. Here are some strategies:
Review Job Descriptions: Ensure descriptions are inclusive and free from language that may unintentionally favour certain groups.

Standardise the Interview Process: Use structured interviews with the same questions for all candidates to reduce bias. Standardised scoring rubrics can also help.
Expand Sourcing Channels: Use a variety of sourcing channels, including those targeting underrepresented groups, to diversify your candidate pool.
Implement Blind Hiring: Remove personal information from resumes (e.g., names, genders) during initial screening to reduce unconscious bias.
Train Recruiters and Hiring Managers: Provide training on unconscious bias and diversity, helping your team recognise and mitigate biases.
Monitor and Audit Hiring Data: Regularly monitor hiring data for adverse impact. Continuous audits help identify and address emerging biases.
Use Technology Wisely: Leverage AI and data analytics to reduce bias in recruitment. Ensure these tools are designed to avoid perpetuating existing biases.
Conclusion
Adverse impact can be tricky to monitor but is a critical concept for talent acquisition managers and HR professionals. Regularly measuring and analysing recruitment processes helps identify biases and enables proactive steps to create a more inclusive workplace. Implementing strategies like structured interviews, diverse sourcing, and bias training can improve recruitment efficiency and contribute to a more diverse workforce. This not only helps with legal compliance and company reputation but also ensures equal opportunities for all candidates.
